Connecting the Main Channel
4-wire Version - Terminal Block
A 5-screw terminal block is located at the rear panel (see Figures 2-2
and 2-7). Five wires, marked TX-A, TX-B, RX-A, RX-B and CHASSIS GND
connect transmit and receive wires and the cable shield (if available).
To connect the main link with the terminal block, proceed as follows:
1. Connect TX connectors at the local unit to RX connectors at the
opposite unit.
2. Connect RX connectors at the local unit to TX connectors at the
opposite unit.
3. Connect the ground wires, if necessary.
4-Wire Version - RJ-45 Jack
Pinout for this version is given in Appendix B.
Dual-Fiber Version
Two SMA or ST connectors, marked TX and RX, are located on the rear
panel. To connect the interface, proceed as follows:
1. Remove the protective caps from the connectors and keep them in a
safe place for later use.
2. Clean both connectors to remove dust accumulated during shipment
(using ethanol or a similar cleaning fluid).
3. Connect the transmit fiber to the TX connector and the receive fiber to
the RX connector, and secure the fastening nuts.
At the remote unit, the transmit fiber must be connected to RX and the
receive fiber to TX.
Caution
Do not overtighten the fiber-optic connectors.

Power
AC power is supplied to the FLM-1 through a 1.5 m (5 ft) cord terminated
by a grounded 3-wire plug. The AC cord is fused at the rear panel AC
power receptacle of the unit. A slow-blow fuse of 0.1A is required for
230 VAC operation, and a slow-blow 0.2A fuse for 115 VAC operation.
