The solution of the following applies to all products with a network port  

Scenario Description

My  LAN is not 192.168.1.Xnetwork segment, it  is 192.168.10.X network segment, subnet mask is, gateway is, I bought your product, and want connect to my LAN, how to do?

2.       Prepare a switch or router and paragraphs cable;

3.       Switch or router energized, the first cable into the Computer´s internet port and switch interfaces, the second cable into the 1W340 device network port and switch interfaces;

4.       Set the computer´s IP for fixed IPand modify the computer´s IP192.168.1.X(X<255, for example192.168.1.28)subnet mask is is192.168.1.1

8.       Router or switch is connected to 192.168.10.X the LAN, or connect the device directly to 192.168.10.X LAN switch or router above;

9.       Change the computer´s IP address back the original (for example:, subnet mask is, gateway is

10.   Open 1W340 softwareselect the device
