Wire to the DH485 Port

The DH485 port can communicate to user devices through the DH485
Communication mode. Use a 1747-C10, 1747-C11, or 1747-C13 interface cable to
connect the module to a link coupler interfaced with the DH485 network.

If you use the 1747-C10 or 1747-C11 cable, it connects between the DH485 port on
the interface module and the J1 (CPU) connector on the link coupler. Power for the
link coupler comes from the interface module.

If you use the 1747-C13 cable, connect it between the DH485 port on the interface
module and the J2 (Peripheral) connector on the link coupler. Power for the link
coupler must be provided from the SLC 500 module DH485 port or external power
source.
