Setting Up Serial Communication
The MGP 464 has two serial communication ports: the RS-232/422 port, accessed
via a 9-pin female D-sub connector on the rear panel, and the Config port, a 2.5 mm
TRS connector on the front panel. These ports are used to connect to a host or
external controlling device, such as a computer or control system, which can
generate the proper command codes and recognize the processor’s responses.
Connector pin assignments
The 9-pin RS-232/422 connector on the rear panel (see the
illustration at right) has the following pin assignments:
The 2.5 mm TRS RS-232 connector on the front panel may be connected to a
