OPERATION
INTRODUCTIONThis booklet describes how to use the ICS-102 and ICS-62 intercom stations and their digital equivalents, the ICS-102T and ICS-62T intercom stations. Station operators can use this manual after the Eclipse System has been correctly installed and configured.
DESCRIPTIONThe ICS-102/102T and ICS-62/62T intercom stations are each assembled in a small, 1-RU high (1.75 in. or 44.45 mm) chassis. The ICS-102/102T has ten selectors while the ICS-62/62T has six. Each station has the following features:
• Individually adjustable listen levels
• Fits in one rack unit (1.75 inches or 44.45 mm) of a standard equipment rack
• Built-in speaker and optional plug-in panel microphone
• Front-panel headset connector
• Call signalling capability
• Answer Back facility
• Local program input without front-panel control
• Programmable relay
• Mute relay
• Two logic inputs for external control of selected station functions
The station can both be equipped with the following options:
• XPL-12 and XPL-22 Expansion Panels
• OPT-100 Auxiliary Audio Output.
FRONT-PANEL CONTROLS AND INDICATORSThe front-panel controls and indicators include:
• Communication-error indicator
• Talk/listen selectors and indicators
• Answer Back facility
• Function buttons
This chapter describes how
to operate the ICS-102 and
ICS-62 intercom stations
and the ICS-102T and
ICS-62T digital stations.

C S - 1 0 2 / 6 2 I N T E R C O M S T A T I O N 1 - 1COMMUNICATION-ERROR INDICATORIf the station should lose data communication with the matrix frame, all of the red lights on the front of the station will flash slowly.
When data communication is restored, the station will automatically return to normal operation.
SPEAKER/HEADSET LEVEL CONTROLSTo adjust the speaker or headset volume, use the knob labeled “intercom,” as described below. The speaker volume can also be affected by three software-controlled functions: Page Override, Mute Level, and Listen Level Adjustment.
INTERCOM VOLUME CONTROLThe “intercom” volume control sets the overall level of all signals coming from the matrix frame, except for the page mode, which is controlled by an internal software function (see the next section “Page Override.”)
PAGE OVERRIDEPage override is a special function in the station in which the intercom volume defaults to a preset to a value when commanded to by the central matrix. Any fixed group can be assigned the page-override function through the configuration program.
The configuration program determines preset value for each station. If the preset value is lower than the setting of the front-panel volume control, the volume will be controlled by the front-panel control.
MUTE LEVELThis turns down the speaker level when any talk is active at the station. The amount of muting (measured in dB) is set by the configuration program for each station. This function helps prevent possible feedback. The maximum amount of muting is 15 dB below full volume. If the front panel control is set below that level, then muting will have no effect.
LISTEN LEVEL ADJUSTMENTThe level of any active listen path can be adjusted individually. Refer to “Listen-Level Mode” later in this chapter.
I C S - 1 0 2 / 6 2 I N T E R C O M S T A T I O N1 - 2
TALK/LISTEN SELECTORS AND INDICATORSThe following section describes the operation of the talk/listen selectors and their associated indicators.
SELECTOR OPERATIONThe selectors operate as both talk and listen selectors; they also work as volume controls when the station is in listen-level mode (see “Listen Level Mode” later in this chapter). Pressing a selector down accesses a talk label; pushing it up accesses a listen label. Pushing the talk selector down and quickly releasing it will “latch” the selector and the talk path will stay active until it is pressed again. Pressing and holding a talk selector causes the talk path to stay active only for as long as it is held down. Listen selectors operate in the same manner.
To prevent the selector on the station from latching in the talk position (local latch disable), or to prevent any station from latching a talk to the station (global latch disable) use the configuration program.
TALK AND LISTEN INDICATORSWhen a talk path is active, the red LED above the selector lights continuously. When a listen path is active, the green LED above the selector lights continuously.
MONITORING/EAVESDROPPING INDICATORSIf any other station begins monitoring a station, a beep (the monitoring-alert tone) will sound at the station.
To inhibit the monitoring-alert tone, use the configuration program.
CALL-WAITING INDICATORIf a station calls another station with a selector programmed for that label, the LED will rapidly flash red. This flashing is a call-waiting tally. To answer the incoming call, push the indicated talk selector. The call-waiting tally clears when the call is answered, or after the call is terminated and the answer-back time-out lapses.
If another station calls a station without a button programmed for that label, it will be placed in the answer-back stack (see “Removing Labels from the Answer-Back Stack.”)
IN-USE TALLY INDICATORIf a selector is assigned to a label and another station is currently using that label, the LED will double-flash once per second to indicate the label is in use. This tally must be enabled from the configuration software.
I C S - 1 0 2 / 6 2 I N T E R C O M S T A T I O N 1 - 3
TELEPHONE OFF-HOOK TALLY INDICATORWhen a telephone interface is assigned to a talk selector, the talk LED will flash once per second if that telephone is off the hook. This tally must be enabled from the configuration program.
RADIO RECEIVER ACTIVE TALLY INDICATORWhen a two-way radio interface port is assigned to a talk selector, the LED will flash once per second when that radio’s receiver is active. This tally must be enabled from the configuration program.
STATION CONNECTED TALLY INDICATORThis tally is used when a station is connected to the frame by a high-speed data line (such as an ISDN or T1 line) that might be inactive periodically. The red LED of any talk selector associated with that station will flash once per second when the station is on-line. This tally must be enabled from the configuration program.
AUDIO PRESENCE TALLY INDICATORWhen a label is assigned to a listen selector, the LED will flash once per second to indicate someone is talking on that channel. This tally must be enabled from the configuration program.
ANSWER-BACK FACILITYThe primary function of the answer-back facility is to answer calls from other stations or interfaces not assigned to a station’s selectors.
The following sections describe the use of the answer-back facility.
ANSWER BACK SELECTORYou use the Answer Back selector to answer calls from stations and interfaces that are not assigned to your station.
When a call from a station or interface not assigned to the station arrives:
• The calling station’s label will be placed in the answer-back stack.
• The red LED will flash.
These two conditions will continue until the call is answered, or until the answer-back time-out period lapses and the caller’s label is automatically removed. To answer the call, push the Answer Back selector. The red LED will turn off and the green LED will turn on, indicating an active talk path to the caller. The talk path is active for as long as the selector is held.
Note: The Answer Back selector cannot be latched; it is a momentary-only function.
Calls from stations or interfaces assigned to station selectors will only be indicated by their associated LEDs.
I C S - 1 0 2 / 6 2 I N T E R C O M S T A T I O N1 - 4
ANSWER-BACK LABEL SELECTIONIf another call comes in while using the answer-back selector:
• The user will hear the caller’s voice.
• The label will be placed in the answer-back stack.
To answer the next caller:
1. Push up on the Answer Back selector to remove the current caller’s label.2. Press down on the Answer Back selector to talk to the next caller.
REMOVING LABELS FROM THE ANSWER-BACK STACKAny label will be automatically removed from the stack if it is not answered within a certain time interval, which is set by the answer-back auto-clear time in the configuration program.
To manually remove the current caller’s label from the answer-back stack, push up on the Answer Back selector.
FUNCTION SELECTORSTwo dual-function toggle switches allow you to choose among the following four functions:
• Panel Mic
• Speaker On
• Mic On
• Listen Level
PANEL MIC SELECTORThis selector selects the panel or headset microphone. If a headset is plugged in, the station will automatically switch to headset microphone operation. If the headset is unplugged, the station will automatically switch back to panel microphone operation. The LED will be on when the panel microphone is active.
SPEAKER ON SELECTORThis selector functions only when a headset is plugged into the station. To toggle the speaker on and off, push the Speaker On selector. The LED indicates when the speaker is on.
MIC ON SELECTORThis selector activates the panel or headset microphone, whichever has been selected. The LED indicates when the microphone is on. If a talk is activated while the microphone is off, it will turn on.
I C S - 1 0 2 / 6 2 I N T E R C O M S T A T I O N 1 - 5
LISTEN LEVEL SELECTORThe Listen Level selector has four functions:
• Activating the listen-level mode
• Resetting the listen-level settings
• Sending call signals
• Releasing auto-answered telephone lines
Listen-Level Mode
To use the listen-level adjust mode, push (for less than 1 sec.) and quickly release the Listen Level selector.
The LEDs of all active listen selectors will begin to flash to indicate the function is on.
Note: Only active selectors can be adjusted in listen-level mode.
Use the selector associated with the intended label to increase (up) or decrease (down) the volume.
To exit, push the Listen Level selector or wait for the 3 sec. time-out.
Note: If the active listen path is pushed higher than the maximum value, the other paths will be driven down so that the desired path has more emphasis.
Listen Level Reset
To reset the Listen Level to default settings:
1. Press (for less than 1 sec.) and quickly release the Listen Level selector.2. Press and hold the Listen Level selector for 3 sec.3. Release the Listen Level selector.
Call Signals
To activate a call signal:
1. Push and hold (for at least 1 sec.) the Listen Level selector until the station indicates it is in Call Signal mode.
2. Push down the talk selector with the desired label.
The call signal will be sent each time the selector with that label assignment is pushed down and will remain so until the call-signal mode times out (about 5 sec.).
Call signals can be issued to any talk label assigned to a station’s talk/listen selectors. If more than one label is assigned to a selector, all labels will receive the signal. If a label is a fixed group, the entire group will receive the call signal. If the label is a party line, then every station listening on the party line will receive the call signal.
I C S - 1 0 2 / 6 2 I N T E R C O M S T A T I O N1 - 6
Remote Telephone Line Release
This function is available only if specifically enabled in the configuration program.
To hang up a telephone interface left off the hook:
1. Push and hold the Listen Level selector for at least 1 sec. to activate the call-signal mode.
2. While holding the Listen Level selector, press the talk selector of the desired telephone’s label.
3. Release the Listen Level selector.
Note: In addition to hanging up the telephone interface, this will deactivate any talk/listen selector set to the interface from anywhere in the system.
REAR-PANEL CONNECTORSThis section describes only those rear-panel functions directly affecting normal station operation. These include the functions available through the “Miscellaneous” connector and those added by the use of the “OPT-100 Auxiliary Audio” connector. The actual functions these inputs and outputs perform depend on the installation of the individual station. This section only describes the general use of these functions. For a more complete description, see the Installation chapter.
MISCELLANEOUS CONNECTORThe Miscellaneous connector includes the following functions:
• Logic input #1
• Logic input #2
• Programmable relay
• Mute relay
Logic Inputs #1 and #2
Each input can control one of several functions, determined through the configuration program. Typically, these inputs are connected to an external foot switch, a panel-mounted switch, or the logic output of another device.
The following functions are available:
• Mic On/Off—toggles the station’s microphone on and off.
• Mute Mic Output To Frame—turns off the audio from the station to the frame. It does not turn off the Hot Mic output
• Mic Off —momentarily turns off the station’s microphone.
• Answer Back Talk/Clear—functions the same as the station’s “Answer Back” selector. Holding down the switch activates a talk to a label in the answer-back stack. To clear the label, quickly press and release the switch.
I C S - 1 0 2 / 6 2 I N T E R C O M S T A T I O N 1 - 7
• Studio Announce—sends the output of the station’s selected microphone (panel or headset) to the station’s Studio Announce (SA) audio output, and activates the SA relay. The microphone output is not sent to the frame. The SA output and relay are only present if the station has the OPT-100 Auxiliary Audio I/O Option installed.
• Speaker OFF—turns off the station speaker, disabling all audible output from the station.
• PTT: Activate All Talk Keys—implements a push-to-talk function for all talk selectors. When the logic input is active, the station operates normally. When the logic input is deactivated, all active talk selectors are disabled. Any controls (relays, etc.) assigned to the labels are activated or deactivated along with their assigned labels. The LED indicators associated with the active talk selectors operate normally regardless of the PTT status. This input only controls latched talks.
• Activate Talk Switch #1— equivalent to pressing the station’s first (leftmost) talk selector; a momentary and latching activation.
• Activate Talk Switch #2—equivalent to pressing the station’s second talk selector; a momentary and latching activation.
• Activate Listen Labels Button—equivalent to pressing the “Listen Labels” button to display listen labels on any display expansion panel (XPL-12 or XPL-22) connected to the station.
• PTT: Activate Two-Way Radio Keys—implements a push-to-talk function for all two-way radio talk selectors. When the logic input is active, the station operates normally. When the logic input is deactivated, all active two-way radio talk selectors are disabled. Any controls (relays, etc.) assigned to the labels are activated or deactivated along with their assigned labels. The LED indicators associated with the active two-way radio talk selectors operate normally regardless of the PTT status. This input only controls latched talks.
Programmable Relay
Each Eclipse system station includes a relay controlled by the system program and independent of the local station function. This relay can be assigned to any label(s) in the system, which will activate whenever a talk or listen is set to that label(s). If activating the relay is the only action desired, assign the relay to a “control” label. See the Eclipse Configuration System Manual for more details.
The relay can activate an external device, such as an applause light in a studio, a cue light, or a security door lock. Any programmable relay in the system can be activated from any station in the system, including a direct-inward-access caller.
Mute Relay
The mute relay is activated whenever any talk selector is activated at the station. The mute relay is commonly wired such that whenever it is activated, the volume of the monitor speaker in that room is decreased (muted).

OPT-100 AUXILIARY AUDIO OPTIONThe OPT-100 Auxiliary Audio option provides the following features:
• Hot Mic output
• SA audio and relay outputs
• Auxiliary audio line level output.
Hot Mic Output
The Hot Mic output is a balanced, line-level, transformer-isolated feed of the signal from the currently selected microphone (panel or headset). The Hot Mic output is active regardless of whether the station has talk paths set and regardless of the front-panel’s control settings.
Studio/Stage Announce Audio and Relay Outputs
The SA output is a balanced, line-level, transformer-isolated feed with the same signal sent to the Hot Mic output, except it is only active when the SA button on the station’s front panel is pressed or when activated by Logic Input #1 or #2, which is configured for the Studio Announce Function.
Auxiliary Audio Line Level Output
The Auxiliary Audio Line Level output is a balanced, line-level, transformer-isolated feed of the input to the station’s internal speaker. For example, this output could be used to feed an external amplifier connected to loudspeakers.
EXPANSION PANEL OPERATIONOptional expansion panels provide additional selectors that operate the same way as a station’s selectors, including talk, listen, tally, and error indication.
The XPL-12 expansion panel provides 10 additional keys, while the XPL-22 provides 20 additional keys. Each expansion panel offers illuminated 5-character labels for every key.
Only one rack unit (1RU) of a standard Electronics Industry Association equipment rack is required for each expansion panel. The panels’ compact size makes them ideal for use in TV control rooms, edit suites, mobile OB vans, and any other location where many talk/listen keys are necessary but space it at a premium.

INSTALLATION
INTRODUCTIONThis chapter describes the installation of the ICS-102/ICS-102T and ICS-62/62T intercom stations, including:
• Station placement
• Wiring
• Mains AC power
• Adjustments
• Configuration
• Accessory panels
MOUNTING STATIONSLocate all intercom stations at comfortable heights for operation and leave at least 2 inches (51 mm) of clearance behind the rear of the station’s chassis to allow for cable connectors.
Accessory panels, that are intended to expand or enhance station operation, are usually mounted next to or near the station with which they are associated. Leave at least 2 inches (51 mm) of clearance behind the rear of the station to allow for cable connectors.
Accessory panels can be located as far as 25 ft. (7.6 m) away from the station. A 6-ft. (1.8 m) cable is supplied to connect them.
WIRINGThis section provides detailed wiring diagrams for all stations’ wiring systems.
Eclipse uses either a twisted, 4-pair transmission, a single-pair twisted, or a coax scheme between the station and the frame using the industry standard RJ-45 connector. Refer to Installing an Eclipse Matrix System: An Overview for RJ-45 connector installation and use, and the type of cable needed for connection between stations and frames.
Most stations have a DB-15M and an RJ-45 connector to connect them to the frame. Stations with only a DB-15M connector include a kit containing one DB-15F/RJ-45 adapter. The adapter allows the use of RJ-45 connectors on both ends of the connection between the frame and the station.
Connections to external devices via the Miscellaneous connector, use the included DB-15M connector to construct one or more cables to connect external devices to the station.

I C S - 1 0 2 / 6 2 I N T E R C O M S T A T I O N 2 - 1
The following sections describe connecting the station to the matrix frame, and all the connections between the station and local devices. Each of the following sections describes cable and station connector wiring:
• Analog matrix frame to station wiring
• Digital matrix frame to station wiring
• Matrix station Miscellaneous connector wiring
• OPT-100 Auxiliary Audio I/O option
• Binaural headset wiring
ANALOG MATRIX FRAME TO STATION WIRINGThe analog audio RS-422 data communications module (COM-10) uses a 4-pair wiring scheme between the frame and stations. This module requires an MVX-A16 card in the frame.
Although some Matrix Stations have a DB-15M (male) connector for connection to the Matrix frame, most have a built-in RJ-45 connector. For those stations with a DB-15 male connector, Clear-Com provides a properly wired DB-15F (female) to RJ-45 adapter for direct connection with RJ-45 terminated cables. Additionally, stations configured for digital communication are equipped with a BNC.
Four-pair analog wiring is typically wired with shielded CAT5 RJ-45 cable.
• Pair 1 transmits analog audio from the matrix port to the station.
• Pair 2 transmits RS-422 data from the station back to the matrix card port.
• Pair 3 transmits analog audio from the station to the matrix card port.
• Pair 4 transmits RS-422 data from the matrix port back to the station.

DIGITAL MATRIX FRAME TO STATION WIRINGThe ICS-102T and ICS-62T stations differ from the ICS-102 and ICS-62 stations because they contain an internal digital audio/data communications module (COM-20) that works in conjunction with the DIG-2 digital interface module to connect digital stations to the matrix.
The DIG-2 digital interface module offers two options for wiring the frame to intercom stations. One option is a single pair of double shielded (braid and foil) 24 AWG conductor CAT-6 Enhanced STP cable with RJ-45 connectors.
The second option, available because only one pair is required, is 75-ohm (RG59) braid shielded coax cable. For this option, a BNC-16 adaptor is required.
In addition, each station may require other connector wiring, depending on what options and accessories are installed.
Note: For more information on the DIG-2 digital interface and the DIF-102 frame which houses it, refer to the DIF-102/DIG-2 manual in the Eclipse set of manuals.
Single-Pair Digital
Single-pair digital wiring requires double-shielded 24 AWG conductor CAT-6E enhanced STP cable with RJ-45 connectors. Pair 1 transmits and receives multiplexed audio or data between the matrix port and the station.
Note: Ensure that the Select switch on the station’s rear panel is in the correct position for the intended use.
Figure 3: Matrix Frame to Digital Station Wiring Using RJ-45
Coax Digital
Coax digital wiring requires double-shielded 24 AWG conductor CAT-6 Enhanced STP cable connected to a 75-ohm (RG59) braid- shielded coax cable with a BNC-16 adaptor.
Pair 1 transmits and receives multiplexed digital and analog between the matrix port and the station.

The following sections discuss how to wire the various functions available on the “Miscellaneous” connector.
Figure 5: Miscellaneous Connector Pinout
External Program Feed Input
The external program feed input allows the station operator to simultaneously monitor audio from an external source and intercom audio.
The input is designed to accept a balanced, line-level audio feed at a nominal level of 0 dB. The program feed input passes through the station’s “Program” volume control before being mixed with the audio at the station. The program

feed (program audio) can be heard on the station’s speaker and headset; it cannot be heard by other stations in the Matrix system.
To connect an external program feed to the station:
1. Connect the balanced audio pair to pins 1 and 9.2. Connect a shield or ground connection if available to the connector’s pin 2
(see Figure 8).
Logic Input #1 and #2
Each input can control one of several functions, determined through the configuration program. Typically, these inputs are connected to an external foot switch, a panel-mounted switch, or the logic output of another device.
The following functions are available:
• Mic On/Off—toggles the station’s microphone on and off.
• Mute Mic Output To Frame—turns off the audio from the station to the frame. It does not turn off the Hot Mic output (described in “OPT-100 Auxiliary Audio I/O Option” on page 2-8). For an example of how to use this option, see “External Program Feed Input” on page 2-4).
• Mic Off —momentarily turns off the station’s microphone.
• Answer Back Talk/Clear—the same functions as the station’s “Answer Back” key. Holding down the switch activates a talk to a label in the answer-back stack. To clear the label, quickly press and release the switch.
• Studio Announce—sends the output of the station’s selected microphone (panel or headset) to the station’s Studio Announce (SA) audio output, and activates the SA relay. The microphone output is not sent to the frame. The SA output and relay are only present if the station has the OPT-100 Auxiliary Audio I/O Option installed. (The SA options are described in “OPT-100 Auxiliary Audio I/O Option” on page 2-8).
• Speaker OFF—turns off the station speaker, disabling all audible output from the station.
• PTT: Activate All Talk Keys (Push To Talk)—when enabled from the configuration program and the logic input is active, the station behaves normally. When this function (logic level) is deactivated, it disables activation of all talk labels, implementing a push-to-talk function for the station. Any controls (relays, etc.) assigned to the labels are activated or deactivated along with their assigned labels. The LED indicators associated with the active labels behave normally regardless of this input’s activity. This input controls momentary and latched talks.
• Activate Talk Switch #1—equivalent to pressing the station’s first (leftmost) talk selector; a momentary and latching activation.
• Activate Talk Switch #2—equivalent to pressing the station’s second talk selector; a momentary and latching activation.
• Activate Listen Labels Button—equivalent to pressing the “Listens” button on the keypad; all modes of the “Listens” button are supported.
I C S - 1 0 2 / 6 2 I N T E R C O M S T A T I O N 2 - 5
• PTT: Activate Two-Way Radio Keys—implements a push-to-talk function for all two-way radio talk selectors. When the logic input is active, the station operates normally. When the logic input is deactivated, all active two-way radio talk selectors are disabled. Any controls (relays, etc.) assigned to the labels are activated or deactivated along with their assigned labels. The LED indicators associated with the active two-way radio talk selectors operate normally regardless of the PTT status. This input only controls latched talks.
Use normally open type switches to activate the logic inputs. Connect the switches as follows (see Figure 8):• Logic input #1—pins 4 to 5 (pin 4 = ground)
• Logic input #2—Pins 11 to 12 (pin 11 = ground)
Note: Do not apply external voltage to the logic inputs.
Mute Relay Contacts
The mute relay is activated whenever any talk selector is activated at the station. The mute relay is commonly wired such that whenever it is activated, the volume of the monitor speaker in that room is decreased (muted). See Figure 8.
Both normally open and normally closed contacts are provided. They are rated at 1 Amp at 24 VDC. This relay is not designed for switching mains AC line voltage. To switch an external device running on mains AC line voltage, use an external relay (or other switching mechanism) activated by this relay.
Programmable Relay Contacts
Each station includes a relay controlled by the system program and independent of the local station function. This relay can be assigned to any label(s) in the system, which will activate whenever a talk or listen is set to that label(s). If activating the relay is the only action desired, assign the relay to a Control label. See the Eclipse Configuration System Manual for more details.
The relay can activate an external device, such as an applause light in a studio, a cue light, or a security door lock. Any programmable relay in the system can be activated from any station in the system, including a direct-inward-access caller. Figure 8 shows the wiring of the relay contacts to the Miscellaneous connector.
Both normally open and normally closed contacts are provided. They are rated at 1 Amp at 24 V DC. This relay is not designed for switching mains AC line voltage. To switch an external device running on mains AC line voltage, use an external relay (or other switching mechanism) activated by this relay.

OPT-100 AUXILIARY AUDIO I/O OPTIONThe OPT-100 Auxiliary Audio option provides the following features:• Hot Mic output
• SA audio and relay outputs
• Auxiliary audio line level output
Figure 9 shows the pinout for the intercom station’s DB-15F Auxiliary Audio I/O connector. Following are descriptions and wiring information for the OPT-100 Auxiliary Audio I/O option.
Figure 6: Auxiliary I/O Connector
Hot Mic Output
The Hot Mic output is a balanced, line-level, transformer-isolated feed of the signal from the currently selected microphone (panel or headset). The Hot Mic output is active regardless of whether the station has talk paths set and regardless of the front-panel’s control settings.
Connect to pins 8 and 15 for a balanced output. Pin 7 is available as a shield or ground source (see Figure 9).
Studio/Stage Announce Audio and Relay Outputs
The SA output is a balanced, line-level, transformer-isolated feed with the same signal sent to the Hot Mic output, except it is only active when the SA button on the station’s front panel is pressed or when activated by Logic Input #1 or #2, which is configured for the Studio Announce Function.
Connect to pins 1 and 9 for a balanced SA audio output. Pin 2 is available as a shield or ground source (see Figure 9).

Both normally open and normally closed contacts are provided. They are rated at 1 Amp at 24 VDC. This relay is not designed for switching mains AC line voltage. To switch an external device running on mains AC line voltage, use an external relay (or other switching mechanism) activated by this relay (see Figure 9). The following table shows the pins available for the SA relay.
Auxiliary Audio Line Level Output
The Auxiliary Audio Line Level output is a balanced, line-level, transformer-isolated feed of the input to the station’s internal speaker. For example, this output could be used to feed an external amplifier connected to loudspeakers.
Connect to pins 6 and 13 for a balanced output. Pin 14 is available as a shield or ground source (see Figure 9).
MAINS AC POWERThe ICS-102/ICS-102T stations and ICS-62/ICS-62T stations can be powered by any source supplying between 12 and 16 V RMS AC at 750 mA. The stations are shipped with a wall-mountable transformer that provides 14 V RMS AC to the station.
Two types of transformers are available: one operates on a mains AC input power of 117 V (part number 730166) and the other operates on a mains AC input power of 220 V (part number 820049). Make sure to specify the proper transformer when ordering the station.
To connect the transformer, route the cord from the transformer’s secondary to the station’s “AC Power Input” connector on the rear panel. This is a 2.1 mm coax connector. When routing the cord make sure to use the stress relief on the rear panel.
The power input to the station is internally protected with a 0.9 a “poly fuse,” a self-healing fuse that will recover when the fault is removed.

ADJUSTMENTSThe following station parameters are adjustable either internally on the station’s main PCB, or externally by selecting options in the configuration program:
• Headset sidetone (main PCB)
• Panel microphone gain (main PCB)
• Speaker mute (configuration program)
• Page volume level (configuration program)
• Station-to-matrix card baud rate (configuration program)
All these parameters are set to factory defaults. Most stations should operate at these default settings; however, some applications may require readjustment.
HEADSET SIDETONESidetone is the sound of the user’s voice in his headset.
To adjust sidetone:
1. Remove the station cover. 2. Find the sidetone control (marked “P2 Sidetone”) on the main PCB. See
Figure 10. 3. Connect a headset to the station.4. While speaking into the headset microphone, use a small screwdriver to turn
the sidetone control until the sidetone is at the desired level. 5. Re-install the station cover.
Figure 7: Sidetone and Panel Microphone Gain Adjustment Controls
PANEL MICROPHONE GAINYou can adjust the preamplifier gain of the panel microphone over a range of 0 to 10 dB; the maximum is the panel microphone gain’s default setting. However, if two stations are talking to each other at the same time with the panel microphone gain set to maximum, feedback may occur even if the speaker mute (see the “Speaker Mute” section, next) is set to maximum. In this case, it will be necessary to turn the panel microphone gain down. Similarly, in some noisy environments it may be necessary to turn the panel microphone gain down and have the operator talk more closely into the microphone.
I C S - 1 0 2 / 6 2 I N T E R C O M S T A T I O N 2 - 9
To adjust the panel microphone gain:
1. Remove the station cover. 2. Use a small screwdriver to adjust the control marked “P1” on the Main PCB.
See Figure 10. 3. Reinstall the station’s cover.
SPEAKER MUTEWhen a panel microphone and a speaker are used together, feedback is possible. To reduce this possibility, the station software will mute (turn down) the speaker level by some predetermined amount when both the microphone and speaker are enabled. The speaker mute can be adjusted from 0 to 15 dB; its default setting is 6 dB.
Refer to the Eclipse Configuration System Instruction Manual for instructions on muting the speaker.
PAGE VOLUME LEVELWhen Page Override is assigned to a label, the audio level at the destination station(s) is predetermined. This function allows talking to someone even if his station’s volume control is off. Two things will happen when a station activates such a label:
• If the destination speaker was off, it will turn on.
• The station’s speaker output will be at the predetermined level regardless of the “Intercom” volume control setting, unless this control is set higher than the predetermined level.
The page volume level can be adjusted within a range of 0 to 10, equivalent to the front-panel control settings of 0 equals off and 10 equals full pot. The page volume level’s default setting is 5.
Refer to the Eclipse Configuration System Instruction Manual for instructions on using Page Override.
STATION-TO-MATRIX CARD BAUD RATEThe RS-422 serial data communication between a station and other devices can operate at standard (19.2 k baud, the default) and long-line (9600 baud) baud rates. Use long-line only if encountering problems with the standard baud rate.
The baud rate is set from the configuration program and the station automatically adapts.

MAINTENANCE
INTRODUCTIONThis chapter provides station microprocessor resetting instructions, troubleshooting guidelines, schematics, assembly drawings, and component lists for the ICS-102/ICS-102T intercom station.
The station operates at 14 VAC, supplied from an external transformer. Transformers can be ordered for either 117 VAC or 220 VAC.
STATION RESETThe station’s microprocessor has a reset button located in an unmarked hole just below the “Intercoms” knob on the left side of the unit’s front panel. If the station is acting erratically, try resetting it by doing one of the following:
• Insert a small screwdriver or a stiff piece of wire (such as a bent paper clip) into the hole and push the reset button.
• Unplug the station from AC power and reconnect.
TroubleshootingWhen experiencing the symptoms listed below, attempt the following solutions in the order outlined. The solutions are listed in order of difficulty with the first being the most simple and easy.
• The station’s LEDs and push-button lights fail to light.
1. Check mains AC power into the station.2. Ensure the external power supply is properly connected to the station.3. Replace the station.
• The LED indicator above a selector key does not light when the key is pressed.
1. Ensure the selector key has a label assigned to it (the LED indicator will not light without an assigned label).
2. Reset the station.3. Replace the station.
• The station appears to activate talk paths, but other stations can’t hear the station operator.
1. Check “Mic On/Off” and “Panel Mic” buttons to ensure the intended microphone is selected and on.
