Extron electronic MGP 464 DI manual Preliminary, MGP 464 Operation

The virtual input buttons are arranged in five columns of three buttons each, reflecting the arrangement of the virtual input connectors on the rear panel. Component video sources must be connected to all three input connectors in a column; S-video sources must be connected to the top two connectors in the column. Composite video sources can be plugged into any connector in the column.

Like the buttons for the four fully configurable inputs, the virtual input buttons light when pressed. When you press an input button connected to a component video source, all three buttons in its column light. If you press a button connected to an S-video source, the top two buttons in the column light. When a composite video source is selected, only one button lights.

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
