RS232
The AMAV switcher can be controlled via the RS232 serial control port to
allow for interfacing to a PC, Crestron or similar third party control system.
The serial communication parameters are 9600 baud, 8 bit, No Parity and
1 stop bit – this is often referred to as 9600 8N1. When the unit recognises
a complete command it will perform the requested action – there is no
delimiter character required.
The unit does not send out a message when a value is changed from the
front panel or by IR control. If the unit needs to be controlled from the front
panel in addition to the RS232 control, you would need to regularly poll the
units’ status to ensure the control system accurately refl ected the current
settings.

STANDBY MODE
Note: Turning the unit System Power Off over RS232 will blank
the displays leaving only the Power Switch LED on. Hard
resetting the unit when in System Power Off mode will return the
unit to normal operation and unlock the front panel.
Even while the unit is turned off by RS232 it will continue to accept and act
upon switching commands. This allows you to set up a ‘scene’ before soft
powering on the unit and enabling the video outputs. The unit will still return
status and change messages in response to commands sent while in System
Power Off mode.
