4.1.1 Overview
The UMCG is designed with two network ports NET1 and NET2.
•Default IP address of NET1: 192.168.0.100
•Default IP address of NET2: 192.168.13.127
Access the WEB interface through the NET1 port by default.
IP addresses of "NET1" and "NET2" should be on different network segments.
If otherwise, communication error occurs.If the IP address of NET2 must be
192.168.0.X, modify the IP address of NET1 to be on another network segment
first.

•Connect PC to NET1 of the UMCG by using a network cable. (NNoottiiccee: Do not enable
the DHCP function of NET1.)
•Set the IP address of the PC to be on the same network segment as that of the
UMCG. It is recommended to set the IP address of the PC to 192.168.0.125, and the
subnet mask to 255.255.255.0.
