4 Connect the power cable to the VGA Splitter power port.
As it receives VGA signals from the VGA source, the VGA
Splitter splits the signal, sending the original signal to the
Frame Grabber and a high-quality copy of the signal to the
VGA display device.
Troubleshooting
If the VGA OUT port is not receiving a VGA signal but the VGA
OUT (fault tolerant) port is, make sure the VGA Splitter is
receiving power.
If neither of the VGA OUT ports are receiving a VGA signal,
check all connections to the VGA Splitter. You should also verify
that the VGA source is operating correctly and that the VGA
display devices are receiving power.
