The video input cables are generally HD15 (VGA) male to male

(such as PC’s COM) you would need a Male/Female DB9 Serial Cable.
. Inputs & Outputs
The VS-2A has 2 video and audio inputs: PC 1 Input and PC 2 Input.
The unit has 1 video and audio output: SW Output. There is a local video
and audio output, which is a loop-out for PC 1 Input: Local.
. Connecting the VS-2A
Connect your video and audio sources such as computer or notebook PC
to PC 1 Input and PC 2 Input. If the loop-out for input #1 is desired, it
can be connected to local video and audio.
Connect the display device such as a monitor (or a video projector) to the
switched video and audio outputs (SW Output).
Connect the included power supply to the VS-2A.
Select the desired mode of operation including the priority for your video
and audio output using the front panel switched buttons. If preferred, the
selection can also be done through RS-232 serial commands by
connecting a DB9 RS-232 Serial cable to your PC and the VS-2A.
