3.2. Reset
At the bottom of S660N receiver, there is a small key besides to Power button, that is the Reset key mainly used to
force turning off receiver if there is something block with power button to switch off the receiver.
For example, if the receiver cant be switched off by power button, use this key to force switching off receiver, then
restart the unit in normal way.
3.3. Self-check
Self-check is an important operation for south receiver during its use on the field. If there is something abnormal on
receiver or the receiver doesnt work properly, performing self-check operation for receiver will be helpful on
judging roughly what happen to the receiver.
Self-check operation is easy to perform on S660N receiver, keep pressing power button for a while (about 8
seconds) until all of indicators light up together, at this moment, release power button and the receiver is
performing self-check procedure, then the indicator will light up one by one from right to left, after that the
self-check is completed and the receiver will get into normal state, starts to track satellites.

Chapter ⅣInternal Web UI Operation
4.1. Overview
Because of using the smart embedded Linux operating system and SOUTH intelligent cloud technology, S660N is
allowed configuring and monitoring the status of itself in real-time on internal web UI. And the accessing way not
only supports the WIFI connection, but also supports the USB connection to computer with the help of LEMO port.
4.1.1. WIFI hotspot connection mode
First of all, the WIFI hotspot is default broadcasted by S660N, search the WIFI hotspot with the name of
SOUTH_xxxx using smartphone, tablet or laptop, then establish the WIFI connection and input the default IP
(10.1.1.1) into explorer, apply the default username and password for login.
For example, search the WIFI hotspot broadcasted by a S660N receiver using laptop PC, choose the WIFI hotspot
and click on connect button to establish the connection without password.
After that, run IE explorer on computer and input the default IP into address bar, after a while, the system login
interface is refreshed, then apply the default username and password for login.

S660N GNSS Network RTK Receiver
4.1.2. USB connection mode
On this mode, the LEMO port of S660N must work as an Ethernet port, then internal web UI shall be accessed via
L7U50 cable connects to computer.
The LEMO port of S660N is default set as Ethernet function, then connect S660N receiver to computer via L7U50
cable. Run the IE explorer on computer and type IP 192.168.155.155 into IP address bar, then input the default
username (admin) and password (admin) for login.

S660N GNSS Network RTK Receiver
At the first time to connect to a computer, a corresponding driver is required to install to the computer, then this
function could be activated.

S660N GNSS Network RTK Receiver
NOTE: The driver can be downloaded from official website automatically or please contact with us for more
supports.

S660N GNSS Network RTK Receiver
If the driver has been successfully installed, the LEMO port of S660N will be recognized as Linux USB
Ethernet/RNDIS Gadget, and a local area connection will generate in Network Connections on the computer.
For example, Local Area Connection 138 generates after connecting S660N receiver to computer via LEMO
Ethernet port.
However, sometimes the computer cannot detect the receiver by LEMO Ethernet port because there is something
wrong with acquiring IP automatically, therefore, we need to do something to avoid such problem, we can set a
fixed LAN IP for the connection: right click on the local area connection which is new generated, choose properties
to call out the local area connection properties window.
Then double click on Internet Protocol Version 4 (TCP/IPv4) option or click on properties button to call out
Internet Protocol Version 4 (TCP/IPv4) properties window, set the fixed LAN IP address as shown in following,
then click OK button and confirm the settings, return to the IE browser and use the IP address 192.168.155.155 to
access the internal web UI.

S660N GNSS Network RTK Receiver
4.2. Web UI Main Interface
As shown in the following screenshot, this is the main interface of web UI of S660 while login, it contains the
common used operation menu and the information window including detail information and settings.
For example, the operation menu is listed at the left column that includes Status, Configuration, Satellite
