4.3. Priority Selection in Auto Mode
The priority button is used to select the priority as NONE or as INPUT
1.
This priority selection only applies to Auto
mode. If INP 1 priority is
selected, the AC1032A-2A will automatically select ‘Input 1' whenever
it detects the presence of video at ‘Input 1’ connector, regardless of
what is happening at the ‘Input 2’ connector.
For example, if the ‘Output’ is playing the video & audio from ‘Input
2’ and video from ‘Input 1’ is detected, the output of the AC1032A-2A
will change to select ‘Input 1’ video immediately. With priority set to
none, the unit stays selected to the current input as long as it is
detecting video there.
4.4 Long Cable Equalization
The use of long DVI cables can cause the ‘Video’ image to degrade to
unacceptable levels.
By pressing and holding BOTH
the ‘Mode SELECT’ and ‘Priority
SELECT’ buttons for 3 seconds, the video boost circuit will be enabled
and the LED’s will flash momentarily acknowledging the selection was
changed. Both of the GREEN LED’s flash when the BOOST is
enabled and the RED LED’s flash when the BOOST is disabled.
4.5 RS-232 Control Port Usage
The AC1032A-2A can also be controlled via a serial device. The unit
operates at a baud rate of 4800 bps. From the serial port, you have full
control over the operation of the switched output, mode, and priority
buttons.
The AC1032A-2A will output a menu to the serial port on power-up.
This menu can also be displayed when the appropriate command is sent
to the AC1032A-2A via the serial port. To view the menu, an ASCII
serial terminal or terminal emulator software is needed. An example is
Microsoft Windows HyperTerminal (generally found in the
Accessories -> Communication folder)
