Safety Information

Operation of any radio transmitting equipment including cellular phones

may interfere with the functionality of medical devices. Consult the

manufacturer of the medical devices if you have any questions. Otherelectronic equipment, especially inadequately shielded telecommunica-

tion and audio systems may also be subject to interference. Ensure

adequate distance from such equipment to minimize interference.

Only authorized personnel should install or service the unit described in

this manual. Faulty installation or service may be dangerous and may

invalidate the warranty.

Basic Installation

Physical installation of the IT-550 cellular gateway:

The IT-550 cellular gateway is housed in an aluminum 19" rack mountchassis. Both the front and the back panel are hinged to allow easy

access to the GSM SIM cards on the channel boards inside.

Securely mount the IT-550 unit in a 19" rack as shown in diagram 1.

Rear PanelFront Panel

Diagram 1: IT-550 Rack Mounting

Allow sufficient space in the front and back for access to the

channel boards.

The power dissipation of the IT-550 is up to 300 watts, make sure toprovide enough air flow access to avoid overheating of the unit.

Special consideration of air flow is required when stacking several

IT-550 gateways or other equipment in a confined space.

Antenna Installation:

The IT-550 cellular gateway includes directional yagi antennas which

provide optimized performance for the IT-550 cellular gateway.

Lay out the antenna locations so that the distance between any

2 antennas is not less then 90cm (3ft) as shown in diagram 2.

Antennas should be kept at least 2m (6ft) apart from any telecom

equipment, cables or cable ducts to avoid interference and noiseproblems.

Make sure the antennas point in direction of the cellular base station.

Mount antennas in vertical direction as shown in diagram 3.

Antenna Installation (cont.):

Use 50 ohm coax cable to connect the antennas to the IT-550

unit. Preferred cabletype is RG-58 for cable length of less then6m (20ft). and RG-213 for a cable length of up to 20m (60ft).

For longer cable runs please contact Flosys technical support.

Mount the coax connectors to the cable. Use a TNC connector at

the antenna end and a BNC connector at the gateway end. Check

for shorts and continuity.

Connect the cables to the antennas.

Connect the cables to the antenna ports on the IT-550 gateway as

shown in diagram 4.

Ethernet connection:

The IT-550 cellular gateway has a 10/100baseT Ethernet

connection to connect it to the configuration and managementconsole.

The connector is a regular Cat-5 modular 8 pin connector as shown

in diagram 7.

Connect either to a Ethernet hub/switch with a straight Cat-5 cable

or connect directly to a Ethernet-NIC in the configuration computer

via a Cat-5 crossover cable.

The initial ethernet TCP/IP setup will be done via the installation

software.

Power connection:

The IT-550 cellular gateway is equipped with a universal AC power

supply.

Mains voltage can be either 110 Vac or 230 Vac 5060 Hz. The

power supply will adjust automatically.

Power consumption is Max. 300 watts. (1.5 3.0 Amp).

Use the included power cord to connect the IT-550 cellular gateway

to a properly fused and grounded AC outlet.

The use of an external UPS (Uninterruptible Power Supply) is highly

recommended to avoid problems with power outages, spikes and

power surges.

The power connector includes the main power switch and the

primary fuse (type 5x20mm 5A / 250V) as shown in diagram 8.

SIM Card Installation:

The IT-550 cellular gateway is capable of utilizing up to 12 SIM cards

per channel. The SIM cards can be rotated manually or automatically byeither timeand / or remaining credit in the case of prepaid cards.

Open the front panel by unscrewing the 3 screws on the top edge of

the panel. Hinge the panel down.

Insert the SIM cards in the SIM card reader slots as shown in

diagram 9.

Open the rear panel and hinge it down. Take care that the wiring

does not get tangled up.

Insert the SIM cards in the SIM card reader slots in the samemanner as used in loading the front SIM card readers.

Start at the top left channel board for channel 17 and continue to

the bottom right board for channel 32 as shown in diagram 11.

Channel 31 and 32 are spare channels which can be activated from

the Configuration Software.

Close the front and rear panel.

The IT-550 cellular gateway is now ready for operation.

NOTE:When the green LED right of a SIM card slot is lit then the SIM

card is currently selectedand in use removing it may disrupt a current

call in progress.


15/20


Troubleshooting

No function at all:

Check that power switch on the back panel is set to ON.

Check that power cord is plugged in and outlet has power.

Check if both green LEDs located on the power supplies on the

back panel are lit. If not check main fuse if fuse is blown replace

with a new fuse (5A/250V).

Red Alarm on T1/E1 interface:

A Red Alarm indicates total loss of connection on a T1 or E1 span.

Check that the T1 / E1 cable is properly plugged into the T1/E1 port

(white port) on the IT-550 and on the proper connector on the

terminating equipment.

Check if either a straight or a cross-connect cable is necessary for

proper operation with your equipment.

If cross-connect is required use a RJ-48 cross-connect cable.

A regular Ethernet Cat-5 cross-connect cable will NOT work.

Poor GSM receive signal:

Check if only a group of channels or all channels are affected by the

poor receiving signal condition.

If only a group of channels (i.e. Ch:1-4) has poor reception:

Check the respective anenna cabling and connectors.

Make sure connectors are fastened tightly.

Check the antenna cable for proper crimping of the connectors.

Check the direction of the antenna pointing towards the GSM

basestation tower.

If all channels are affected by poor GSM signal reception.

Make sure the antennas point in the direction of the GSM

basestation tower.

Check that the antennas are mounted with their directors in a

vertical position.


16/20


Buzzing noise during calls:

If there is buzzing noise during phone calls very likely this is caused

by interference from the GSM transmitter antennas.

Make sure the antennas are at least 6ft / 2m apart from any telecom

equipment, cables or cable ducts to avoid interference and noise

problems.

Make sure the IT-550 cellular gateway is properly grounded.
