188 Setting Up the DH-485 Network
Configuring the SLC 5/03, SLC 5/04, and SLC 5/05 Channel 0 for
DH485 Protocol
The RS-232 port (channel 0) of the SLC 5/03, SLC 5/04, and SLC 5/05
processor can be configured for DH485 protocol. Refer to your
programming software user manual for software configuration
information.
You can connect channel 0 of the SLC 5/03, SLC 5/04, and SLC 5/05
processors to a DH485 network using the 1747-CP3 cable and a
1761-NET-AIC Advanced Interface Converter (AIC+). In this case, the
AIC+ must be powered with 24V dc. The 1746-P1, 1746-P2, 1746-P4,
1746-P5, and 1746-P6 power supplies provide 24V dc user power
which may be used to power the AIC+.
