INSTALLATION INSTRUCTIONS FOR XRD-8050

All that is required for normal operation of the FIBERLINK XRD-8050 stand-

alone unit is to connect signal, power and the fiber optic cables between units

and to set the internal DIP switches for the correct mode of operation.

Installation Procedure

The following procedure is intended to simplify the installation of the XRD-

8050 unit. Be sure to follow all steps carefully and to double check all connec-

tions. Specific details regarding the various functions follow this procedure.

1) Connect the traffic signal controller to be used to the DB-25S signal

connector on the XRD-8050. The mating plug is a standard DB-25P and the

pin connections are tabulated in the "SIGNAL CONNECTIONS" section

that follows.

2) Connect operating power to the 3 position terminal block on the XRD-8050

as per the information in the "POWER SUPPLY CONNECTIONS" section

that follows.

3) Remove the top cover on the unit and set the ANTI-STREAMING and

MASTER/LOCAL switches as required per the information in the appropri-

ate section that follows.

4) Connect the XRD-8050 units being used together with fiber optic cable. Be

certain that the proper "transmit" (T1 or T2) connector of one unit is

connected to the proper "receive" (R1 or R2) connector of the other units.

Note the information in the "OPTICAL FIBER" section that follows.

5) The system should now be operational.

Note that the transmitting element in the "-7"

single-mode version of the XRD-8050 uses a solid

state Laser Diode located in the optical connector on

the unit. This device emits invisible infra-red radiation

which may be harmful to human eyes. As a result,

direct viewing of this radiation should be avoided.
