Chapter 2. Logging to the Device
This chapter describes how to configure TCP/IP settings on your computer, and how to login to the
Device. In addition, it briefly describes the layout of the Device’s Web interface.
2.1 Configuring Your Computer
To configure the Device via Web UI, you need to properly configure TCP/IP settings on the computer
that you use to manage the Device. To achieve this, follow below steps:
Step 1 Connect the computer to a LAN port of the Device.
Step 2 Install TCP/IP protocol on your computer. If it is already installed, please skip this step.
Step 3 Do one the following step to configure TCP/IP settings on your computer:
(1) If you want to set the IP address and other settings manually, select Use the
following IP address, set the IP address to an unused one in the 192.168.1.0/24
subnet, subnet mask to 255.255.255.0, and default gateway to 192.168.1.1. Note:
the Device’s default LAN IP address is 192.168.1.252 with a subnet mask of
255.255.255.0.
(2) If a DHCP server is available on your network, and you want IP settings to be
assigned automatically, select Obtain an IP address automatically and Obtain
DNS server address automatically.
Step 4 Use the Ping command to verify network connectivity between the computer and the
Device. Open the command line interface on the computer, type ping 192.168.1.252, and
then press Enter.
A successful ping will look like this.

UTT Technologies Logging to the Device
http://www.uttglobal.com Page 9
An unsuccessful ping will look like this.
If the Ping command is successful, the connection between the computer and the Device is working
properly. If the Ping command fails, please follow these steps:
