Figure 2.4 1747-C13 Cable Connection
The 1747-C13 cable acts only as a communication link and does not carry 24V dc
power. The 24V dc can come from either the processor or an outside power
source. The 1747-C10 or 1747-C11 cable carries 24V dc power from the
processor to the link coupler. (The 1747-C10 and 1747-C11 are interchangeable.)
A cable connected to the outside power source carries 24V dc from the outside
power source to the link coupler.
The module and SLC 500 CPU act as two separate nodes on the DH485 network.
Refer to the following sections for additional information on some of the
components shown in the previous figures.
1747-AIC Isolated Link Coupler
The 1747-AIC Isolated Link Coupler allows you to link modules to the DH485
network. Figure 2.2 and Figure 2.3 show a DH485 network with the module and
a personal computer linked to the network through a 1747-AIC link coupler.
1747-PIC Interface/Converter
Use the 1747-PIC Interface/Converter to convert the RS-232 signals from the
personal computer’s serial port to RS-485 signal format. Figure 2.2 shows the
interface/converter integrating a personal computer with the BASIC development
software to the module across a DH485 network.

IMPORTANT
When using the BASIC development software to interface with
the module through the 1747-PIC, the BASIC development
software must be configured for DH485 communication through
the configuration and terminal selection menus. Refer to the
BASIC Development Software Programming Manual (publication
number 1746-PM001A-US-P) for additional information.
