Figure 1.7 DH485 Network Configuration
The 1747-PIC interface/converter converts the RS-232 signals from the
personal computer RS-232 serial port to RS-485 format. The 1747-AIC
link coupler links the converted signals with the DH485 network and
port DH485 on the module. Port DH485 must be configured as the
program port in order to communicate with PBASE software via the
DH485 network.
See Chapter 3 for additional information on port configuration.

IMPORTANT
Each module requires a link coupler port to interface
it with the DH485 network.
When using the BASIC development software to
interface with the module, 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 1746-PM001, for additional information.
