Config port
— This configuration port on a 2.5 mm TRS connector is an alternative to
the RS-232/422 port on the MGP Pro rear panel. However, unlike the rear panel port, it
supports only RS-232 (see
Rear Panel Features
on page 6 for a description of the rear
panel RS-232/422 port).
Both of the MGP Pro serial ports are used for system configuration and control.
Commands are received through these ports from the computer, 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 is available from Extron and can be used
to connect your computer to this port. Figure 12 shows the configuration and pin
assignments of this cable.
