Switching Modes
The GV-NET/IO Card provides two modes for users to expand its capability: I/O Box Mode
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.
Note: It is required to install the USB driver. For details, see Installing USB Driver later in the
Installation Guide.

Extended Connections
Via the RS-485 connectors, up to 4 GV-NET/IO Cards can be chained together when the GV-
NET/IO Card is on the I/O Box mode. For extended connections, the address assignment is
shown below.
Note: When the GV-NET/IO Card is set to the I/O Box Mode, it can have extended
connections with GV-I/O Boxes.

Installing USB Driver
To use the USB function, it is required to install the driver on the PC. Follow these steps to
install the driver:
1. Insert the software DVD. It will run automatically and pop up a window.
2. Click Install GeoVision USB Devices Driver. This dialog box appears.
3. Click Install to install the drivers. When the installation is complete, this message will
appear: Install Successfully.
4. Click Exit to close the dialog box and restart the PC.
To verify the drivers are installed correctly, go to Windows Device Manager after restarting
the PC. Expanding the Ports field, you should see Prolific USB-to-Serial Comm Port or
XR21B1411 USB UART depending on the version of the driver. The COM number in the
parenthesis indicates the COM port currently in use.
Note: If you unplug the GV-NET/IO Card from the PC and connect another GV-Net/IO
Card to the same USB port, the COM port may still be changed. Access the Windows
Device Manager again to look up the new COM port number.
