1747-PIC Interface/Converter/1747-AIC Isolated Link Coupler
Use the 1747-PIC interface/converter to convert the RS-232 signals from
the personal computer’s serial port to DH-485 format. This figure shows
the interface/converter integrating a personal computer with the PBASE
software to the BASIC module across a DH-485 network.

The 1747-AIC isolated link coupler allows you to link modules to the
DH-485 network.

Important: When using PBASE to interface with the BASIC module
through the 1747–PIC, the BASIC development software must be
configured for DH-485 communication through the configuration and
terminal selection menus. Refer to the BASIC Development Software
Programming Manual (publication number 1746-6.2) for additional
information.
