How to Configure the Cellular Modem USR-GPRS232-730?
2020-05-18

Question:

I have bought a cellular modem USR-GPRS232-730 from your shop en.usr.cn , please tell me how to configure the cellular modem? 

 

Answer:

The main function of our USR-GPRS232-730 is network transparent transmission, but our cloud platform receives data by MODBUS RTU protocol. Are you uploading your data to our cloud platform? Or just want to use our test server: test.usr.cn for basic testing?
 

If you want to use the test server for basic testing, you can follow the default settings in the setup software. When sending data from the serial port, the test server will return the same data to your serial port.

If you need to connect to our cloud platform, you can refer to this article: https://www.usriot.com/news/modbus-rtu-test-of-cellular-modem-usr-gprs232-734.html
