Figure 1.9 DH485 Network Configuration Using a 1747-C13 Cable
The 1747-C13 cable acts only as a communication link and does not carry 24V dc
power. The 1747-C10 or 1747-C11 cable carries 24V dc power from the processor
to the link coupler as shown above. (The 1747-C10 cable and 1747-C11 cable are
interchangeable.)
You can also supply power to the link coupler by connecting the 1747-C10 or
1747-C11 cable from the link coupler to the module and not to the processor.
The 1784-KR DH485 Interface Card enables the personal computer to
communicate with the DH485 network. The DH485 data link connector on the
1784-KR card and port DH485 on your module are interfaced with the DH485
network through a 1747-AIC link coupler.
Port DH485 must be configured as the program port in this configuration. See
chapter 3 for additional information on port configuration.

IMPORTANT
When the 1747-C13 cable is used, you can connect the center
port on any link coupler on the network directly to the module.
This may reduce the number of link couplers that you need.
(Compare the amount of equipment shown in figures 1.8 and
1.9.)
