3 WEB UI
There are two ways to login the WEB interface, which are Ethernet port login and WIFI login. The
WEB interface content of the two login modes is same.
(1) Ethernet port login : Connect the RJ45 network port with the computer host, and enter the IP on
the NET20 PLUS display in the browser for NET20 PLUS access. Enter the user name and password
in the pop-up dialog box, and the default username and password are : admin - password.

3.3.1 Reference Station
This page mainly sets the reference station, antenna, and reference station parameters, as shown in
gure 3-8.
Figure 3-8
Reference station coordinates : If you do not need a known coordinate to start reference station,
then click the “Load Current Position” as a reference station coordinate. However, if you need a
known coordinate to start reference station, please input the known point coordinates in accordance
with the appropriate format. The web access port is 80. After setting mapping in the router device,
then you can access the NET20 PLUS by Internet.

3.3.5 Ntrip Server
In this page, the user could set the transmission content and the server for the NET20 PLUS reference
station.
Figure 3-13
3.3.4 Network
This page is mainly set for the data link method used by NET20 PLUS, as shown in gure 3-11.
DHCP : If the model DHCP is enable, the NET20 PLUS receiver will auto get IP address, otherwise it
uses the static IP.
WIFI hotspot : After power on WIFI hotspot, then you can use other devices with WIFI function to
search and connect to this NET20 PLUS receiver. The hotspot is named by driver serial. You don’t
need to input password when connect to the WIFI hotspot. Access NET20 PLUS by IP address
192.168.10.1. The hotspot only play the role of control and can’t access internet.
WIFI Client : When selecting WIFI client, in SSID box input a name of WIFI hotspot can be used for
the search, and in the Password box input the password for connecting to WIFI hotspot, then submit.
After connecting to the connection WIFI, the password can be seen in system terminal or panel
interface (the displayed place will be different in different versions).
