Entering the Startup Mode After batteries have been installed, power on the CD47C Time-Based Benchmarker by depressing the ON/OFF

power button which is located on the right side of the unit. If installed, unscrew the stainless steel switch cap to gain

access to the recessed power button. Once power is applied, the CD47C enters the STARTUP mode and displays

the CDI logo on the Backlit LCD and cycles the audible alarm along with the 16 high intensity LEDs, ON then OFF

twice. If removed, replace the power button switch cap to prevent accidental power disruptions of the CD47C while

it is in the field. Refer to Figure 5, Startup Screens.

Figure 5, Startup Screens

Before the CD47C proceeds to Startup Screen 2, it quickly retrieves its last configuration setting from non-volatile

flash memory. This configuration can be a combination of user and/or default values that are set through the Menu

System (refer to Accessing the Menus). Once the configuration has been read from memory, the CD47C initializes

and configures either the Bluetooth radio or the RS232 interface for file transfers. File transfers from the CD47C to

a computer running Marker software can be initiated only when the unit is in STARTUP and SUSPEND modes

(refer to Downloading Data). After the file transfer interface has been configured, the CD47C flashes the 16 LEDs

once and then sequences through Startup Screens 2 - 4. The screens are updated every three seconds and the

sequence will continue until the unit is placed into the Menu System or the RECORD mode. As an additional visual

aide to the user, a Startup LED, top left, will flash every time a STARTUP screen is advanced.

Startup Screen 3 and 4 provide the user with both unit configuration and status information. This information

should be verified by the operator prior to placing the unit in the RECORD mode.

Startup Screen 2

Figure 5, Startup Screens 2, instructions the operator to press the RECORD buttons simultaneously to place the unit

in the RECORD mode. Passages and Ignored events are detected and saved only when the unit is in the RECORD

mode.

Startup Screen 3

Figure 5, Startup Screens 3, displays the Signal to Noise ratio that the unit requires in order to record a pig passage.

The default value is 0.5:1, but is configurable through the Menu System. Also displayed is the battery voltage,

which is constantly measured and updated with the current value. It is recommended that new D-cell batteries be

installed prior to deploying the CD47C in the field. New batteries will typically indicate a voltage of 3 volts or

greater. Memory usage is the last value displayed. Erased, memory indicates 0.17% utilization due to the stored

configuration settings occupying memory space. Additional passages can be appended to previously recorded data,

however it is recommended that memory be erased prior to deploying the CD47C on a new run.

Startup Screen 4

Figure 5, Startup Screens 4, displays the firmware version that the unit is running under. Please contact CDI to

obtain the latest firmware version.

User Configuration Settings before entering the Record Mode

Before entering the CD47C‟s RECORD mode for the first time after power-ON, the unit‟s user configuration values

should be set through the Menu System (refer to Accessing the Menus for detailed discussion). Typical

configuration values that are adjusted for include: ACQUIRE POST GPS, LOCAL TIME ZONE, RECORD MODE,

and RESET FILE MEMORY.

Entering the Record Mode Passages and Ignored events are detected and saved to non-volatile memory only when the CD47C is in the

RECORD mode. The RECORD mode can be accessed by simultaneously pressing the RECORD buttons from

either the STARTUP screens or the SUSPEND mode. Every time that the unit enters the RECORD mode it will

compensate for environmental noise by setting new threshold levels for the Magnetic and/or Transmitter Channels.

If the unit enters the RECORD mode from the STARTUP screens it will also need to acquire an initial GPS time and

position before data can be recorded.

Determining Magnetic Environment

To minimize false triggers on the Magnetic and Transmitter Channels, the CD47C compensates for the

environmental noise at its current location by automatically adjusting the threshold levels of both channels. The

goal of this routine is to compensate for environmental noise, but maintain sensitivity so that actual pig passages can

be detected. If the CD47C is unable to accomplish this goal a warning message is displayed on the LCD, refer to

Figure 8 Compensating for Magnetic Environment fails.

Figure 6 Increasing the Threshold Overcomes Magnetic Noise

Background Magnetic Interference (Noise)

Operating Sensitivity Level (Threshold)

Initial Sensitivity Level (Threshold)


of 20

The task of compensating for the environment noise begins by setting the thresholds to initial values, magnetic

threshold = 0 and transmitter threshold = 10. Then a timer with an initial setting of 45 seconds begins to count

down. During the countdown, if a channel detects a false trigger, its threshold is increased by 2 and the timer is

reset back to 45 seconds. The routine has successfully completed when the thresholds have been adjusted to

minimize environmental noise and the timer has counted down to zero, refer to Figure 7, Determining Magnetic

Environment.

Figure 7, Determining Magnetic Environment

To help speed up the routine and make it more efficient, the CD47C will only monitor the active channels as set in

the Menu System (refer to Accessing the Menus). If the RECORD mode is set for both magnetic and transmitter

detection, then both channels will have their thresholds compensated for. Otherwise, only the active channel,

magnetic only or transmitter only will have its threshold adjusted for when compensating for environmental noise.

If time warrants, the process can be bypassed by simultaneously pressing the RECORD buttons. If this is the first

time that the compensation routine has run, bypassing will set the thresholds to magnetic = 10 and transmitter = 30,

otherwise the thresholds are set to the values obtained from the previous time that the routine was able to run to

completion.

Figure 8, Compensating for Magnetic Environment fails

If the Magnetic Environment routine fails, either the CD47C needs to move to a quieter location and restarted or the

excessive noise source needs to be eliminated.

Acquiring Initial GPS Time and Position

GPS information is used in all of the CD47C‟s time calculations for pig passages, and is a necessary step for the

CD47C to function properly in the field. If the CD47C enters the RECORD mode from the STARTUP screens it

will need to acquire an initial GPS time and position before data can be recorded. Once the Magnetic Environment

test is complete, the CD47C will immediately begin to acquire an initial GPS time and position, refer to Figure 9,

Acquiring Initial GPS Time and Position.

The CD47C will first attempt to acquire an accurate GPS time and then an accurate GPS position. The CD47C‟s

internal GPS module needs to receive the signals from at least 4 orbiting GPS satellites to acquire valid GPS time

and position. If the module receives less than 4, the Satellite Signal is Unacceptable message will be displayed on

the LCD. If the module receives the signal from 4 or more satellites, the Satellite Signal is Acceptable message will

be displayed on the LCD. The LCD display and button side of the CD47C needs to have clear access to an open sky

for its internal GPS module to perform properly and receive enough satellite signals to acquire GPS time and

position.

Press RECORD simultaneously to load default threshold values


of 20

Figure 9, Acquiring Initial GPS Time and Position

While acquiring GPS time and position, if communications with the internal GPS module is valid, a series of

sequencing asterisks will be displayed on the LCD. The series is a constantly repeating pattern of 0 to 3 asterisks,

incrementing every 1 to 3 seconds. If the series fails to increment, internal communication problems with the GPS

module are occurring. If problems arise, the CD47C should first be powered OFF, battery voltages checked and if

necessary, the batteries replaced. Next, power the unit back ON and reenter the RECORD mode by pressing the

RECORD buttons simultaneously. If internal GPS communication problems still persists the unit will need to be

taken out of service and repaired.

After approximately 20 minutes, if the CD47C is unable to obtain valid GPS information due to problems with

either the communication to its GPS module or the module is unable to acquire enough satellites needed for

obtaining accurate GPS time and position, a warning message will be displayed, refer to Figure 10, Warning

Message if Acquiring GPS Fails.

Figure 10, Warning Message if Acquiring GPS Fails

Detecting Pig Passages

Once environmental noise has been compensated for by adjusting threshold levels and an initial GPS time and

position has been obtained, the CD47C is in the RECORD mode. The CD47C‟s Magnetic and/or Transmitter

Channels are now active and any Passages or Ignored events that are detected are saved to non-volatile Flash

memory.

When the CD47C is in the RECORD mode, the LCD display will sequence through two screens every five seconds.

The screens inform the user of the last acquired GPS position and that the unit is actively waiting to detect pig

passages, refer to Figure 11, Detecting Pig Passages. Both screens contain information regarding the unit‟s startup

time, the current time, and if present, the time that the last pig passage was detected and stored into memory. As an

additional visual aide to the user, a RECORD mode LED, bottom right, will flash every time a screen is advanced.

Figure 11, Detecting Pig Passages

Analyzing Events Screen

When in the RECORD mode, the CD47C will only detect the signal of the active channel(s). The active channel(s)

can be set in the Menu System (refer to Accessing the Menus) to be MAGNETIC only, TRANSMITTER only, or

BOTH. When the duration of the detected signals from the active channel is long enough, as when a pig passage

occurs, the CD47C begins to save the received data to its non-volatile memory. As the data is being saved the LCD

backlight comes on and the LCD informs the user that the CD47C is analyzing a magnetic disturbance, refer to

Figure 12, Analyzing Magnetic Disturbances.

If the total duration of the detected signal is long enough and its signal to noise ratio is acceptable, the CD47C posts

the disturbance as a valid pig passage. Once the pig has passed and is out of range of being detected by the

CD47C‟s active channel, the CD47C closes the saved passage record by storing additional information that is used

by CDI‟s Marker software. This additional record information is necessary and valuable when analyzing the

CD47C‟s data. The information includes: Time, Position, Battery Voltage, Temperature, Number of previously

stored Ignored Events, Threshold Values, Firmware Version, Serial Number, S/N ratio, GPS Version, etc.

Ignored Events Screen

When in the RECORD mode, if the duration of the signal is too BRIEF, the magnetic disturbance is considered not

to be an actual pig passage, but instead possible noise and the data is saved in non-volatile memory as an Ignored

Event. If the duration of the detected signal is long enough but exceeds the limits of the signal to noise ratio, the

magnetic disturbance is considered too NOISY and the data is saved as an Ignored Event, refer to Figure 13, Ignored

Events. Typically, environmental noise is cancelled out when the active channel(s) thresholds are set prior to

entering the RECORD mode. However, while waiting for a pig passage to occur, environmental conditions and

sources of noise can change, resulting in false triggering of the active channel(s).

OR

Figure 13, Ignored Events

The information saved from a resulting Ignored Event includes: the Time that the event was detected, Date, too

Brief or too Noisy, Battery Voltage, Temperature, Peak Signal Level, etc. The Ignored Event record information is

necessary and valuable when analyzing the CD47C‟s data in CDI‟s Marker software. Only when the data is

analyzed can the event be truly classified as an Ignored Event.

Post GPS Screen

When in the RECORD mode and Post GPS is enabled in the Menu System (refer to Accessing the Menus), the

CD47C will attempt to acquire new GPS information after a valid pig passage has been detected, refer to Figure 14,

Acquiring a Post GPS. Although obtaining a Post GPS after every passage is not absolutely necessary, under certain

circumstances it can enhance the time calculations during data analysis. There is a minute amount of drift to the

CD47C‟s internal clock, which can accumulate between long intervals of GPS acquisitions. Every time that the

CD47C acquires new GPS information, it resets its internal clock, thus minimizing any possible drift.

Figure 14, Acquiring a Post GPS

When the CD47C is configured to acquire a Post GPS, the routine can be bypassed at the operator‟s discretion by

simultaneously pressing the BYPASS buttons. Bypassing the routine can be helpful if time is of the essence and the

unit needs to be placed in the SUSPEND mode and moved to a new location. When the routine is bypassed, the

CD47C performs as if Post GPS was not enabled and no passage data is lost.

Entering the Suspend Mode The CD47C can safely be moved to another location when in the SUSPEND mode. Although still present, detected

signals from the active channel(s) are ignored, preventing any additional data being stored to memory, refer to

Figure 15, Suspend Mode. The SUSPEND mode can even be accessed while the CD47C is analyzing a magnetic

disturbance, refer to Figure 12, Analyzing Magnetic Disturbances. This can be helpful, if the operator inadvertently

creates a false disturbance while trying to place the unit into the SUSPEND mode or if the unit is accidently moved

before being placed in suspend. To enter the SUSPEND mode, press the PAUSE buttons simultaneously.

Figure 15, Suspend Mode

When the CD47C is in the SUSPEND mode, the LCD display will sequence through a series of two screens every

five seconds. The first screen informs the user that passage detections are suspended and the CD47C can be moved

without generating false triggers. The second screen instructs the user to press the RECORD buttons simultaneously

to resume recording pig passages. Both SUSPEND mode screens contain, if present, the time and date of the last

pig passage that was detected by the unit. As an additional visual aide to the user, a SUSPEND mode LED, bottom

right, will toggle on and off every time a screen is advanced.

Downloading CD47C data while in the Suspend Mode

The CD47C will allow for data downloads to CDI‟s Marker software only when the unit is in either the STARTUP

mode or the SUSPEND mode. When the CD47C is in the RECORD mode, its sole task is to detect pig passages.

The CD47C can be configured to download data from its non-volatile memory using either a serial download cable

or its internal Bluetooth transmitter (refer to Downloading Data). The user can select the method of downloading

data in the Menu System (refer to Accessing the Menus).

Synchronizing to GPS time while in the Suspend Mode

The CD47C is capable of synchronizing external devices such as, pc‟s, laptops, tools, etc. to its acquired GPS time.

The CD47C will automatically perform this operation via a serial download cable, only if the acquired GPS time is

less than one hour old. This one hour restriction ensures the accuracy of the GPS time. A newer GPS time can be

acquired by either restarting the unit and acquiring a new initial GPS time or by selecting GET GPS NOW in the

Menu System (refer to Accessing the Menus).

The cable used for synchronization is the same cable that is used for data downloads. The serial download cable has

a four pin circular connector on one end and a standard DB9 serial connector on the other. The circular connector

mates to a bulkhead connector on the side of the CD47C and the DB9 to the device that is to be synchronized. The

serial cable uses a standard RS232 configuration for TX, RX, and Ground, plus an additional Pulse per Second

(PPS) signal from the GPS module on pin 9 of the DB9. The serial interface is configured for 9600, 8, E, 1 and the

protocol used to request and receive the GPS time and date packets is described in the CDI document “Requesting

the GPS time from a CD47”, which is available upon request.

Accessing the Menus The Menu System allows the operator to customize the CD47C‟s default settings, initiate special functions, or

perform basic housekeeping routines. The unit‟s operating configuration can be a combination of user and default

settings that are set through the Menu System. The configuration settings whether user defined or default are saved

into the CD47C‟s nonvolatile Flash memory and are retained when the unit is powered off. The Menu System

consists of three top level LCD screens that can be navigated through by using the Button Bar assigned UP/DOWN

pushbuttons, refer to Figure 16, Top Level Menu Screens. As the operator moves UP/DOWN through the Menu

System, a reverse field cursor indicates the active menu item on the Menu screen. Pressing the ENTER button for

the active menu item selects that item and the CD47C drops into its associated Submenu Screen, thus allowing the

operator to change its value.

When no buttons are pressed for 20 seconds, the CD47C will exit out of the Menu System due to inactivity and

return to the operating mode it was in prior to entering the Menus. The operator can also exit from either the top

level Menus or Submenus at any time by pressing the ESCAPE button. No changes are made to the Submenu item

if the operator presses ESCAPE before the ENTER button is pressed.

Figure 16, Top Level Menu Screens

Submenu Screens

There is a Submenu Screen for every menu item of the three top level Menu Screens. It is at the Submenu level that

the menu item‟s value is changed.

Acquiring Post GPS

Figure 17, Acquiring Post GPS

In Figure 17, Acquiring Post GPS, the UP/DOWN arrow pushbuttons are used to toggle between NO/YES and

pressing ENTER selects and saves the setting. Selecting „YES‟, the CD47C will attempt to acquire new GPS

information after a valid pig passage has been detected. Once the new GPS information has been acquired, the

CD47C‟s internal clock is reset, it‟s time slaved to the new GPS time, and the new GPS information is saved into

nonvolatile memory. Although the CD47C‟s internal clock is highly accurate, acquiring new GPS information can

enhance the time calculations during data analysis. The default Post GPS setting is YES.

Setting the Local Time Zone

Figure 18, Setting the Local Time Zone

In Figure 18, Setting the Local Time Zone, the UP/DOWN arrow pushbuttons are used to increase/decrease the Time

Zone setting and pressing ENTER selects and saves the setting. Setting the Time Zone only affects the local time

that is displayed on the LCD module. It is solely for the operator‟s convenience and does not affect the times stored

by the unit for pig passages. CDI‟s Marker software, used for CD47C data analysis, uses the GMT times that the

CD47C records in its nonvolatile memory. Setting the Time Zone to zero will display the pure GMT time. The

default Time Zone setting is -6, the Time Zone for CDI in Tulsa, Oklahoma.

Setting Threshold Levels

Figure 19, Setting Threshold Levels

In Figure 19, Setting Threshold Levels, the UP/DOWN arrow pushbuttons are used to increase/decrease the

threshold level for the Magnetic and/or Transmitter Channels. Refer to Determining Magnetic Environment for an

understanding of and reason for the need to set the threshold levels. Although the procedure is performed

automatically by the CD47C prior to recoding data, the operator has the ability to bypass the routine and load either

fixed bypass values, or previously determined values, or the values that have been set in the Menu System. The

Menu System will allow the operator to first set the Magnetic threshold value and secondly to set the Transmitter

threshold value. Pressing ENTER will select and save the new setting, pressing ESCAPE will retain the previous

setting. The fixed Bypass Threshold settings are MAGNETIC: 10 and TRANSMITTER: 30.

Setting the Signal to Noise Ratio

In Figure 20, Setting the Signal to Noise Ratio, the UP/DOWN arrow pushbuttons are used to increase/decrease the

Signal to Noise Ratio. The Signal to Noise Ratio is one of the parameters used to validate a magnetic event as being

a pig passage. Increasing the ratio puts a tighter restriction on validating a magnetic event as being a pig passage.

Decreasing the ratio loosens the restriction, making it easier to classify a magnetic event as being a pig passage. The

operator needs to be careful not to set the ratio too high (true passages will be posted as IGNORED EVENTS) or too

low (Noise will be posted as PIG PASSAGES). The default Signal to Noise setting is 0.5 : 1.0.

Setting Delay ON when coming out of Suspend

Figure 21, Delay ON when coming out of Suspend

In Figure 21, Delay ON when coming out of Suspend, the UP/DOWN arrow pushbuttons are used to

increase/decrease the delay time. The delay time can be adjusted from 0 to 24 hours. The first hour can be set in

increments of 10 minutes; afterwards the delay time is incremented by the hour. The delay time setting becomes

active when the unit is in the SUSPEND mode and the RECORD buttons are pressed. Then, the delay time begins

to count down to zero, which is visible on the LCD display. When the countdown reaches 0, the CD47C returns to

its normal operation, setting thresholds values and detecting passages. The countdown can be bypassed by pressing

the RECORD buttons simultaneously. A new delay time needs to be entered for each Delay ON routine. The

default Delay ON setting is 00:00:00.

Setting the Active Receive Channel(s)

In Figure 22, Setting the Active Receive Channel(s), the UP/DOWN arrow pushbuttons are used to cycle the

selection of the Active Channel(s) from BOTH, MAGNETIC, TRANSMITTER. Any Passages or Ignored events

that are detected by the Active Channel(s) is saved to non-volatile Flash memory. Any data on a channel that is not

active is ignored. The default Active Receive Channel(s) setting is BOTH.

Setting the LCD Contrast

Figure 23, Setting the LCD Contrast

In Figure 23, Setting the LCD Contrast, the UP/DOWN arrow pushbuttons are used to increase/decrease the contrast

setting of the LCD display. Pressing ENTER accepts the setting, pressing ESCAPE retains the current setting. The

default LCD Contrast setting is 36.

Setting the Serial Number

Figure 24, Setting the Serial Number

In Figure 24, Setting the Serial Number, the UP/DOWN arrow pushbuttons are used to increase/decrease the

CD47C‟s Serial Number. The unit‟s Serial Number is displayed on the LCD display and is used by CDI‟s Marker

Software to identify the CD47C and tag its data when downloading for analysis. The Serial Number of every

CD47C is initially set by CDI during production. While CDI has other means it can use to track a CD47C that has

had its Serial Number changed, operators should use caution when using this feature.

Acquiring Current GPS Information

Figure 25, Acquiring Current GPS Information

In Figure 25, Acquiring Current GPS Information, the UP/DOWN arrow pushbuttons are used to toggle between

NO/YES and pressing ENTER selects and saves the setting. After selecting „YES‟, the CD47C will immediately

attempt to acquire new GPS information. Once the new GPS information has been acquired, the CD47C‟s internal

clock is reset, it‟s time slaved to the new GPS time, and the new GPS information is saved into nonvolatile memory.


of 20

Although the CD47C‟s internal clock is highly accurate, acquiring new GPS information can enhance the time

calculations during data analysis.

Selecting the Device for Downloading Data

Figure 26, Selecting the Device for Downloading Data

In Figure 26, Selecting the Device for Downloading Data, the UP/DOWN arrow pushbuttons are used to toggle

between RS232 (serial download cable) or Bluetooth (wireless). Pressing ENTER selects and saves the setting. The

CD47C is equipped with an internal Bluetooth transmitter, while the serial download cable is a standalone cable that

mates to the CD47C and the serial port of a personal computer or laptop. Refer to Downloading Data for detailed

information. The default Device for Downloading Data is Bluetooth.

Resetting File Memory – deletes memory and retains current configuration

Figure 27, Deleting Data while keeping Current Configuration

In Figure 27, Deleting Data while keeping Current Configuration, the UP/DOWN arrow pushbuttons are used to

toggle between NO/YES and pressing ENTER immediately initiates the selection. When file memory is reset, all

data stored in nonvolatile memory is erased, however the CD47C‟s current configuration is retained. Warning – All

Data is Erased!

Restoring Defaults – deletes memory and restores default configuration

Figure 28, Deleting Data and Restoring Defaults

In Figure 28, Deleting Data and Restoring Defaults, the UP/DOWN arrow pushbuttons are used to toggle between

Downloading Data Downloading data to CDI‟s Marker software can be accomplished when the CD47C is in either the STARTUP

mode or the SUSPEND mode. The CD47C can be configured to download data from its non-volatile memory using

either a RS232 serial download cable or wirelessly using its internal Bluetooth transmitter. The user can select the

device for downloading data in the Menu System (refer to Accessing the Menus). When the CD47C is configured

for RS232 serial cable downloads, a download cable icon is displayed in the Configuration Column of the LCD

display, refer to Figure 29, Suspend Mode and Configured for RS232. When the CD47C is configured for Bluetooth

downloads, a Bluetooth icon is displayed in the Configuration Column of the LCD, refer to Figure 31, Suspend

Mode and Configured for Bluetooth. The Configuration Column of the LCD is viewable when the CD47C is in the

RECORD and SUSPEND modes.

Downloading data from a CD47C requires that CDI Marker software, version 3.179 or newer, be installed on either

a pc or laptop computer. Version 3.179 or subsequent versions can be installed on computers running Microsoft

Windows 98 2nd Edition/2000/XP SP2/Vista operating systems. Version 3.179 or subsequent versions are backward

compatible with earlier versions of the CD47 Benchmarkers. Customers that already have Marker installed can

determine its version by going to About Marker… from the Help pull down menu. A CD with the latest version of

Marker is shipped with new orders of the CD47C. CDI also provides customers with an internet link of the latest

version for immediate download. An extensive help section in Marker can assist the operator if any issues arise

during data downloads or normal operation.

RS232 Serial Cable Downloads

The serial download cable, available from CDI, has a four pin circular connector on one end and a standard DB9

male serial connector on the other. The circular connector mates to a bulkhead connector on the side of the CD47C

and the DB9 to a computer or laptop that has CDI‟s Marker software installed on it. Marker software automatically

handles all serial port settings and the download communications protocol with the CD47C. The user only has to

inform Marker, in the download dialogue window, which serial port to use, refer to Figure 30, Marker Screenshot

during Serial Cable Download.

Figure 29, Suspend Mode and Configured for RS232

The CD47C is equipped with a Bluetooth Version 2.0 serial module that supports wireless downloads. The module

is a Class 1 device with a possible range of 300 meters. The actual download range may be reduced by the

limitations of the pc/laptop computer‟s Bluetooth device and/or environmental conditions. The pc/laptop computer

running Marker software needs to be equipped with a properly installed and functioning internal or external

Bluetooth device. CDI can provide its customers with an external USB Bluetooth module or recommend a

compatible device.

Wireless downloads from the CD47C are both safe and secure. Maintaining security was paramount during the

design of the Bluetooth interface for both the CD47C and Marker software. First, Marker only recognizes CD47C

Bluetooth devices and ignores all others. Second, pairing of devices requires a specific and proprietary passkey.

Third, the transmitted data is encrypted. Fourth, the data format and communication protocol is unique and

application specific. This means that the CD47C‟s Bluetooth device does not conform to typical Bluetooth profiles

and is therefore more secure.

The user can select the Bluetooth device for downloading data in the Menu System (refer to Accessing the Menus).

Once Bluetooth is selected, the CD47C will automatically configure and control all wireless downloads. The only

user intervention required is to issue the START TRANSFER in Marker software.

When the Bluetooth module is discoverable, can be detected by a computer running Marker software, the CD47C‟s

top second from right side LED is turned ON. During Bluetooth downloads, the CD47C‟s top third from right side

LED flashes ON/OFF for each data block that is transferred to Marker. The flashing LED provides an additional

visual conformation to the user that a download is in progress and that data is being transferred successfully.

Bootloader – updating the CD47C’s operating system Warning - caution should be used when accessing the Bootloader, the CD47C’s operating system could be

erased!

The purpose of the Bootloader is to erase the operating system that is currently in memory and replace it with a new

one. The Bootloader allows customers to update the CD47C‟s operating system quickly and easily using the RS232

download cable and the serial port of a personal computer or laptop.

A terminal emulation program that supports communications over the COM port will need to be installed on the

personal computer or laptop. HyperTerminal is an emulation program that is supplied with Microsoft Windows and

is suitable. In the emulation program, configure the COM port for: Bits per second – 57600, Data bits – 8, Parity –

None, Stop bits – 1, Flow control – None, and select the COM port that the download cable is plugged into.

A CDI supplied .hex file contains the CD47C‟s operating system. The .hex file is small, under 200K, so it can

easily be attached in emails for quick distribution to customers and downloads to the CD47C.

Use the following procedure to update the CD47C‟s operating system:

1. Connect the download cable to the CD47C and serial port of the pc/laptop.

2. Configure and select the COM port in the terminal emulation program, 57600, 8N1, NONE.

3. While pressing the CD47C‟s LEFT most GREEN pushbutton power ON the unit.

4. Verify that LDRv1.1>_ is displayed in the emulation program.

Warning – the following step will erase the operating system!

5. Press the CD47C‟s RIGHT most RED pushbutton.

6. In the emulation program, select Transfer, Send Text File and select the CDI supplied .hex file.

The CD47C will issue a series of beeps during the download and the process will take about 30 seconds to complete.

Once the download is complete the CD47C will immediately begin its normal startup routine, beeping twice and

displaying the CDI logo on the LCD display. Verify that the Firmware Version displayed in the CD47C‟s startup

window agrees with the version of the downloaded .hex file.
