3. Source = Aux On / Aux Off
These commands are issued when the Aux button is pushed. When the
Aux On command is sent, the Aux button illuminates, and vice versa.
These commands can be used for additional projector control, or to
toggle the VSA-32’s relay to raise/lower a screen, etc.
4. Power = On
This command will be issued when the Power button is pressed and the
Power button LED is off. This command would normally tell the projector
to power on.
Note: We recommend inserting a 15-45 second wait after the power on
serial command to allow the projector to completely power up before
sending it more serial commands. (The time to wait will vary with the
projector model)
5. Power = Off
This command will be issued when the Power button is pressed and the
Power button LED is on. This command would normally tell the projector
to power off.
Note: We recommend inserting a 45-90 second wait to allow the
projector to completely power off before sending it more serial
commands. (The time to wait will vary with the projector model)
