. Operating the VSA-31-SP
To operate the VSA-31-SP, first press the power button. The power
button on the VSA-31-SP will now light up. If you have uploaded a serial
command for the “Power = On” command then that serial command will
now be issued to the projector. Next, select an input 1-3 by pressing the
corresponding button. The button you just pressed will light up and the
serial command associated with that button will be sent to the projector. In
addition to issuing serial commands to the projector the VSA-31-SP
Transmitter will also switch the source of the video being transmitted to
the Receiver to the input you just selected. Only 1 video source will be
transmitted to the VSA-31-SP at any given time. Volume is adjusted by
selecting either A/V or Mic with the “Vol Sel” button and turning the
volume knob. You will see the volume level indicated by the volume LED
bar. Volume level is adjusted per input and saved in memory for each
input.
Pressing the “POWER ON” button while a source is on will result in the
POWER = ON serial string being sent to the projector and then the
corresponding SRCx=ON serial string being sent. This is done so the
projector and the VSA-31-SP panel remain synchronized.
If the microphone has been disabled in the optional settings, the user is
prevented from changing the “Vol Sel” button, adjusting the microphone
volume or changing the microphone mute status. If microphone operation
is desired, it must be enabled via the GUI.
. Resetting the VSA-31-SP
If for any reason you need to reset the VSA-31-SP, press buttons 1 and 3
simultaneously and the unit will reset. This will not result in the loss of
any serial command programming; this will only reboot the unit. All the
serial commands are still stored in the unit. You may need to press the
power on button and reselect the input you wish to display depending on
the optional settings used.
