6.1 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. Download and install the USB Driver from the website.
2. Click Install to install the drivers. When the installation is complete, this message will
appear: Install Successfully.
3. 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 XR21B1411 USB UART. The COM
number in the parenthesis indicates the COM port currently in use.
Note: If you unplug the GV-I/O Box 16 Ports from the PC and connect another GV-I/O
Box 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.

1. Addresses 0 and A to F are NOT functional.
2. Assign the addresses when the power is off.
3. If you want to change the assigned address of the connected GV-I/O
Box, set the switch to the new address and re-plug the power
adaptor.

6.3 Extending Transmission over the Distance
When the transmission signals between the RS-485 communications become weak over the
distance, switch on the Terminal Resistance Switches to maintain their stability. Three
conditions below illustrate the typical scenarios in which the Terminal Resistance Switches
should be switched on.
1. Multiple pieces of GV-I/O Box are connected with the PC through one single
RS-485 cable.
After you connect multiple pieces of GV-I/O Box with the PC, only switch on the Terminal
Resistance Switches in the first and last connected pieces of GV-I/O Box.

Note: If you connect GV-IO Box 4 Ports V1.2 as the first device to the PC, do not use
the USB cable. Instead, use the RS-485 cable and you need the optional device GV-
Hub, GV-COM, GV-NET Card or GV-NET/IO, to connect the RS-485 device to the PC.
2. Multiple pieces of GV-I/O Box are connected with the PC through a RS-485
converter.
After you connect multiple pieces of GV-I/O Box with the PC through a RS-485 converter,
such as GV-NET/IO Card and GV-Hub, insert a Terminal Resistor in the converter and
switch on the Terminal Resistance Switch of the last connected GV-I/O Box.

3. Multiple pieces of GV-I/O Box are connected with the PC through separate RS-485
cables.
After you connect multiple pieces of GV-I/O Box with the PC through separate RS-485
cables, switch on Terminal Resistance Switches of the connected piece of GV-I/O Box at
the end of each cable.

The default setting of the Switch is OFF. To switch on the Terminal
Resistance Switch, push the switch downward.

7. Accessing GV-I/O Box 16 Ports over Networks
You can link the GV-I/O Box to GV-DVR / NVR / VMS, GV-ASManager and GV-Control
Center over networks for I/O management. While accessing the GV-I/O Box, make sure the
connected network is stable and the following system requirement is met:
Microsoft Internet Explorer 8.0 or later
There are three ways to set up GV-I/O Box on a network:
1. By default, when the GV-I/O Box is connected to a network with DHCP server, a
dynamic IP address is assigned to the GV-I/O Box.
2. When the DHCP server on your network is unavailable or disabled, the GV-I/O Box is
accessible by the default IP 192.168.0.100. See 7.1 Fixed IP Connection for details.
3. You may also use the DDNS (Dynamic Doman Name system) instead of an IP address
to access the GV-I/O Box. For details on the domain name service, see 7.2 DHCP
Connection.
Note: Notice these specifications for GeoVision software applications:
1. GV-I/O Box is linked to GV-DVR / NVR / VMS by using the Virtual I/O function. GV-
DVR / NVR / VMS supports up to 9 I/O modules which include real and virtual I/O
devices linked through the network.
2. Up to 16 connections from GeoVision software are allowed to control one GV-I/O Box.

7.1 Fixed IP Connection
To assign GV-I/O Box to a fixed IP:
1. Open an Internet browser, and type the default IP address https://192.168.0.100. The
login dialog box appears.
2. Type default value admin for both Username and Password, and click OK. This page
appears.
3. In the Machine Name field, edit the name of the connected GV-I/O Box.
4. Click Disable. Type the static IP address information, including IP Address, Subnet
Mask, Default Gateway and Domain Name Server.
5. Click Submit. When the setting is complete, the Status field will indicate Register
Success. Then GV-I/O Box can be accessed through the fixed IP address.
Note: If want to use the domain name instead of an IP address, you may use the Domain
Name Service. For details on domain name service, see 7.2 DHCP Connection.
