and NET/IO Card Mode. With a mode-switch jumper to insert on the 2-pin header, you can
switch between modes.
NET/IO Card Mode (default): With the switch jumper inserted, this default mode acts as a GV-
NET/IO Card . It is required to connect the GV-NET/IO Card to the GV-Video Capture Card for
usage.
I/O Box Mode: Without the switch jumper inserted, the GV-NET/IO Card can work as an
independent device. It is NOT necessary to connect to the GV Video Capture Card for usage.
