If you need information on how to set up your network, see form 1796, the Guide to Networking
Opto 22 Products. This guide provides detailed information on how to make your groov network
more secure by separating control network traffic from the computer network. It also describes how
to directly communicate with groov over the Internet using a virtual private network (VPN) or with
port forwarding (PF). While PF is easier to set up, a VPN is recommended because it is more secure.
Assigning a Static IP Address
If you do not have a DHCP server, you’ll need to configure a static address to either ETH0 or ETH1.
Otherwise there may be communication errors.
NOTE: If you are using a laptop computer to assign an IP address, make sure you disable Windows’ Internet
Connection Sharing (ICS). If you don’t, the laptop will act like a DHCP server and assign a dynamic address.
You’ll need to get the following networking information from your IT department:
• IPv4 address—A unique, fixed (static) IP address.
For example: 172.18.234.1
• Netmask—Identifies the subnetwork.
For example: 255.255.225.0
• Gateway (optional)— Identifies the route to the Internet.
For example: 172.18.1.1
1. Click the Configure Network Interfaces icon in Quick Start.
2. Click the wired Ethernet connection you want to configure.
NOTE: Use ETH0 as the main network connection. Only use ETH1 if you have segmented networks.
