RS-232
Atlona’s AT-COMP-88M can be controlled via the RS-232 serial control port to allow for interfacing to a
PC. The serial communication parameters are 9600 baud, 8 bit, No Parity and 1 stop bit - this is often
referred to as 9600 8N1.

iter character required. The unit does not send out a message when a value is changed from the front
panel or IR control. If this unit needs to be controlled via the front panel in addition to the RS232 control,

STANDBY MODE
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.
