RS-485
Connect Cable to the
DH-485 Port The DH485 port can communicate to user devices through the
DH-485 Communication mode. Use a 1747-C11, 1747-C10, or
1747-C13 interface cable to connect the module to a link coupler
interfaced with the DH-485 network.
If you use the 1747-C11 or 1747-C10 cable, it connects between the
DH-485 port on the module and the J1 (CPU) connector on the link
coupler. Power for the link coupler will come from the interface
module.
Refer to page A-1 for more information.
Connect to the DH-485 Port via the 1747-C11 Cable
If you use the 1747-C13 cable, it connects between the DH-485 port
on the module and the J2 (Peripheral) connector on the link coupler.
Power for the link coupler must be provided from some other source.
