Setting Up Serial Communication

Software Configuration and Control

The MGP 464 can be configured 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.

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.
