Gpi Control - Datavideo DVK­100 Mk II Instruction Manual

To grab the freeze frame image press the Still button. The Still button will be illuminated
red, it will remain red while the freeze frame is being held. You will see the Foreground

GPI Control
The DVK­100 has a GPI In and Out port.
The GPI In will allow remote switching between the CAM­1 and CAM­2 Inputs.
The GPI In Socket is 3.5mm. Wire a cable as follows:
If the switch is closed the DVK­100 will switch to CAM­1, if the switch is open it will switch to CAM­2.
The GPI Out Socket will replicate the GPI In socket, like a loop through. You could use this to control a
second device simultaneously; or maybe to remotely monitor which channel is active (CAM­1 or CAM­2)
The GPI Out will also switch when the CAM­1 or CAM­2 buttons are pressed, CAM­1 is open circuit, CAM­2
is closed circuit. It would be possible to use the GPI Out to start / stop a device each time you switch from
CAM­1 to CAM­2, or possibly switch devices.
