GV-NET Card V3.2
The GV-NET Card is a RS-485 / RS-232 interface converter. This Card connects to the RS232 port or USB port on your computer, and allows RS-485 devices, such as PTZ domes, to
be connected through the Card.
System Requirements
If the GV-NET/IO Card is listed as Prolific USB-to-Serial Comm Port under Windows
Device Manager, GV-System version 8.2 or above is required. If the GV-NET/IO Card is
listed as XR21B1411 USB UART under Windows Device Manager, GV-System version
8.5.7.0 or above is required.
To see how to check the device name under Windows Device Manager, refer to Installing
USB Driver later in this Installation Guide.

Connections with Two Video Capture Cards
If your system is equipped with two video capture cards, connect the GV-NET/IO Card to the
video capture card of 1-16 channels.
Connections in NET/IO Card Mode
For the connections in the NET/IO Card Mode, please follow the instructions below:
• It is required to connect the GV-NET/IO Card to GV-Video Capture Card with the 20-Pin
Ribbon Cable.
• If you want to connect the GV-NET/IO Card to RS-485 devices, you have three ways of
connections. See below.
Three Ways of Connections of GV-NET/IO Card and RS-485 Devices:
1. You can connect a RJ-11 to DB9 Cable to the PC's COM Port when a RS-485 device is
connected. (Allowed for AC/DC Output Voltage)

Connections In I/O Box Mode
For the connections in the I/O Box Mode, please follow the instructions below:
• It is not necessary to connect the GV-NET/IO Card to GV-Video Capture Card.
• Connect the GV-NET/IO Card to the PC by one of the following three ways.
Note: When you want to use any of GV-I/O 12-In Card and GV-I/O 12-Out Card with GV-Net/IO
Card, it is required to use both of 12-In Card and 12-Out Card together for work.

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.

Extended Connections
Via the RS-485 connectors, up to 4 GV-NET/IO Cards can be chained together when the GVNET/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.
