Software Conguration and Control
PRELIMINARY
The MGP can be congured and controlled by software via the following interfaces:
RS-232 or RS-422 (Simple Instruction Set [SIS•
™
] commands or Windows
®
-
based control software)
LAN (Web pages, SIS commands, or Windows-based control software)
•
This chapter discusses the use of the SIS commands and how to access the
Windows-based control software. For instructions on using the Windows-based
control software, refer to the software's Help program. See chapter 5, "HTML
Configuration and Control," for information on using the Web pages.
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 Cong 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.
