of the selected input has been adjusted to the –10 dBV internal reference level.)

Front Panel Security Lockout (Executive Mode)

The front panel security lockout limits the operation of the switcher from the
front panel and optional IR remote control. When the switcher is locked, the Enter
button, I/O button (video, audio, or video and audio selection), and all of the
front panel audio gain and attenuation functions are disabled. The front panel
input and output buttons continue to allow ties to be viewed, but ties cannot be
created.
The front panel security lockout also disables the IR remote sensor to lock out
remote control functions.
Press and hold the Enter button and the Preset button simultaneously for
approximately 2 seconds to toggle the lock on and off.

Selected SIS Commands

The table below shows a partial list of SIS commands the you can use for operation and configuration of the switcher.
For a complete listing, see the MVX Matrix Switchers User Guide. Run the following commands from a PC connected to the
RS-232 port (item d on page 1). Set gain (G) and set attenuation (g) are the only case sensitive commands
