The line driver/receiver module is a plug-in module that mounts in one slot
of the two-slot chassis. Card guides on the top and bottom of the rack and
locking tabs at the front hold the module securely. The module's edge
connector receives DC operating voltage from an integral power supply.
Two 15-pin connectors are mounted on the front of each module, one male
and one female. Two I/O Interconnect Cables (cat. no. 1778CR) or Belden
8723, connect the A (male) connectors of the four required modules (figure
4). One 1770-CW1 cable connects the PLC-2 family processor with the B
(female) connectors on the modules at one end of the link. A 1770-CW2
cable connects the B (female) connectors on the modules at the other end
of the link with the industrial terminal.
A red LED indicator is mounted on the module front plate and lights when
you connect the first line driver/receiver module to the second line
driver/receiver module.
