4 Wire Data with Contact Closure Card Connectors
Connect fiber optic cable
Fiber Link cards are equipped with two optical connectors. Connect fibers to the transmitter and receiver
marked TX and RX. Connect the transmitter (TX) fiber on one card to the receiver (RX) fiber on the other
card and vice versa. Always route fiber cable loosely, avoiding tight bends.
Connect 4 wire data pairs
The analog voice-frequency data transmission supports full duplex constant transmission up to 9600 bps.
The module has a contact output that corresponds to the contact input on the opposite end module.
The copper pairs from the CO or PBX connect to the green SEND/INPUT and RECEIVE/OUTPUT screw-
down terminals on the CO Card.
The copper pairs from the remote terminal connect to the green SEND/INPUT and RECEIVE/OUTPUT
screw-down terminals on the Sub Card.
Connect contact closure leads
Connect the contact closure leads to the black contact closure INPUT and green Contact Closure
OUTPUT screw terminals. The INPUT of one side corresponds to the OUTPUT at the other end. The
contact input is a dry contact only. Output is a normally open contact only.

Contact Closure Connection Diagram
Contact closure operation status may be determined from the 2 status LED’s. The red LED is ON when
the input is active, and OFF when no input is present. The yellow LED is ON when the contact closure
output is closed, and OFF when the output is open.
