Atlona AT COMP 44M - Manual (Page 8)

Note: Turning the unit System Power Off over RS232 will distinguish the LED display leaving only the Power
Switch LED on. The Video and Audio outputs will also mute. While the unit is turned off by RS232 it will
continue to accept and act upon switching commands. For example, if the unit is in the OFF Mode
(via RS232) and you send a command to switch an input to an output, that route will complete and the
video and audio will now appear on that channel only. The front panel LED for that particular output will
also show the input selected (for that single output channel only). The remaining LED’s will remain off
and video and audio outputs muted. The unit will still return status and change messages in response
to commands sent while in Power Off state. A hard reset command (SBALLRST) will return the unit to
normal operation and also unlock the front panel.
