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.

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.
