A/V mute modes are activated via SIS commands sent to the CTR 8. The COM port then
sends SIS commands to the switcher. The table below shows the different commands that
the COM port sends for each A/V mute mode.

LED Responses for Video Muting
The CTR 8 allows button LED responses to indicate when video is muted. Button LEDs are
controlled by the Tally Output signal. The CTR 8 offers three different LED modes, which are
set by sending SIS commands to the Remote RS-232 port.
•
LED Mode 0 = LED of selected input is always on (Default)
•
LED Mode 1 = LED of selected input turns Off when muted
•
LED Mode 2 = LED of selected input blinks when muted
NOTE:
LED mode can be set only when A/V Mute Mode is 1, 2, or 3. If A/V Mute Mode
is 0, LED mode is 0.
