Setting Up Serial Communication
The MGP 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
computer via the optional 9-pin D to 2.5 mm stereo mini TRS RS-232 cable
(part #70-335-01). The pin assignments are shown below.
