10Config port — This configuration port on a 2.5 mm TRS connector is an alternative to the RS-232/422 port on the MGP rear panel; however, unlike the rear panel port, it supports only RS-232. (For a description of the rear panel

RS-232/422 port, see “Rear Panel Features” in chapter 2, “Installation”).

Both of the MGP’s serial ports are used for system configuration and control. Commands are received through these ports from the PC, using SIS commands or the Windows-based control software. Both serial ports can be active at the same time.

The protocol for this configuration port is as follows:

•9600 baud

•8 data bits

•1 stop bit

•No parity

•Always RS-232

An optional 2.5 mm TRS configuration cable (part #70-335-01) is available from Extron and can be used to connect your computer to this port.

The diagram on the next page shows this cable’s configuration and pin assignments.
