Configuring SLC 5/01 and SLC 5/02 Processors
APS versions 2.0 and later support DH-485 point-to-point communication. Y ou can
connect APS to the SLC 500 processors using a 1747-PIC Interface Converter , a
1770-KF3 module, or 1747-KE module. A 1747-AIC Link Coupler is required for
DH-485 network communication.

Node Address
Each device on the DH-485 network must have a unique node address. The default
node address for APS is 0, and the default for the processors is 1. T
o change a
processor node address, write a value between 1 and 31 using the Who function.
The change is applied immediately.
Baud Rate
Each DH-485 network device must have a common baud rate. The table below
shows the available baud rates. Y ou must cycle power to apply the new baud rate.
Processor Baud Rate
Fixed and SLC 5/01 9600 or 19200
SLC 5/02 1200, 2400, 9600, or 19200
