1-10 Module and Development Software Overview
Figure 1.7 shows the module interfaced with a DH485 network through a
1747-AIC Isolated Link Coupler. The link coupler also provides an interface to the
DH485 network for a personal computer with the BASIC Development Software.
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 number 1746-PM001A-US-P) for additional
information.
