Extron Electronics MTPX Plus Series User Guide - Manual (Page 24)

Remote Connection
Connect a host device, such as a computer, touch panel control, or RS-232 capable PDA to
the switcher via the remote port of your switcher.
NOTE: The port can operate at 9600, 19200, 38400, or 115200 baud rates. Models
other than the MTPX Plus 128 can support either the RS-232 or RS-422 serial
communication protocol (see “
Selecting the Rear Panel Remote Port
Protocol and Baud Rate ” in the “Operation” section to configure the Remote
port from the front panel).
If desired, connect an MKP 2000 or MKP 3000 remote control panel to the Remote
connector of the switcher. Refer to the MKP 2000 Remote Control Panel User Guide or the
MKP 3000 Remote Control Panel User Guide for details.
