1. Quick Start
1.1.
Test Hardware Environment
Serial data between PC and G800 in transparent transmission (LAN interface)
Computer visits Internet through G800 (4G interface)
USR-G800 router is used to realize the function of connecting to 4G network for users, while users do
not need to concern the details, which can work after simple setting. Parameter setting can be achieved
through router built-in web page, permanent stored for once setting.
This chapter is introduction of quick get start, we suggest users read this chapter and operate one time
according to the instructions, then users will have a systemic understanding for this 4G router product, while
users can also choose those interested chapters to read according to their need.
Questions can be submitted to our customer support center: http://h.usr.cn
As G800 possesses multiple communicating interfaces, we choose the below two functions to test.
Connect router’s RS232 port with computer’s RS232 port through female to female serial extended line,
meanwhile, make connection between LAN port with PC by RJ45 cable.
Regarding to connection of serial port, G800’s serial port is RS232 level which needs to connect to
computer’s own RS232 interface, or through USB-RS232 converter to connect to computer (Note: Both of the
two types of connection should use female to female cross serial lines), hardware connection is as below

Testing Software:
Open the testing software “USR-TCP232-Test.exe”, please refer to the following picture:
Com Setting Side:
Port Number: Check the computer’s currently used port number COM4 (find it in device manager)
Baud Rate: 115200 (Default value of G800 router)
Click Open
Net Setting Side:
Protocol: TCP Client ( G800 work as TCP server, so PC have to be worked as TCP client)
Server IP:192.168.1.1 ( G800’s IP address)
Server Port: 8899
Click connect, if there is no mistake for the above processes, TCP connection can be built.
Click send buttons in the two sides, corresponding data can be received in the opposite side.
At this point, data transmission can be tested between serial port and network:
Data from serial port to network: PC’s serial port->router serial port->router ethernet (wifi) ->PC network
Data from network to serial port: PC network->router ethernet (wifi) ->router serial port->PC serial port
