RS-232 and RS-422 Remote Connections

The DXP switchers have two serial ports through which the DXPs can be configured via SIS
commands (serial commands that control the switcher through this connector).

NOTES:
If desired, you can connect an MKP 2000 or MKP 3000 remote control panel to this port.
See the user guide of either product for details.
RS-232 Config port (front panel)
The Config port is an additional RS-232 connector, located on the front panel. A host
device can be connected to this port for serial RS-232 control only. Protocol for the port is
the same as for the rear panel Remote RS232/RS422 port: 9600 baud, 8 data bits, 1 stop
bit, no parity, and no flow control.
