Thank you for purchasing the VGA-2 input selector. The VGA-2 is a high
bandwidth 2 input RGBhv input selector allowing two different contents to
be shared with a single input on a monitor or projector. The unit features
both a manual mode and automatic mode to meet all of your installation
requirements.

Power Connections
The VGA-2 requires 9-24vdc at 100ma in continuous operation.
The startup current draw is 800ma for 50 milliseconds so your power supply
must be able to supply that initial current rush. Most wall transformer supplies
are able to supply the current required. Some regulated supplies may limit
the inrush current well and may not work unless they are rated above 800ma
continuous duty.
Operating via Infrared Control
The VGA-2 can be controlled via IR remote signals. The IR input connection
through the terminal block allows the VGA-2 to be hardwired into the IR
repeater system. The VGA-2 will operate on any repeater system that is
based on 0vdc for no IR signal and +5 to +12vdc for an active IR signal. The
VGA-2 infrared commands operate at 38KHz.
When an IR code is being received through either method, the IR confirm
LED will blink
Teaching IR Commands
The VGA-2 is capable of teaching it's 38KHz IR control codes to most
models of learning remotes and controllers. The teaching emitter will output
the code for an input selection when a source selection button is pressed on
the unit.

Placing the VGA-2 into Automatic Mode
The VGA-2 ships with the default mode set as manual control. This allows
infrared, dc voltage and pushbutton control of the unit.
The VGA-2 can be operated in an automatic mode that will switch to the B
input on detecting a video signal. When the signal is no longer present on the
B input the VGA-2 will switch back to the A input.
To change the VGA-2 into the automatic mode a jumper inside the unit needs
to be placed across two terminals. The default has the jumper attached to
just one of the terminals.
