UART setting parameters: 115200, 8, 1 None
Enable heartbeat packet: www.usr.cn, time: 30s
Note: RS232 and RS485 share 1 UART, choose one of them to use.
Test Steps:
1. Open setup software, select the UART parameters, such as serial port number, baud rate and open
serial port, see below image:
2. Power on, then the POWER led will be on, several seconds later, the GPRS led will be on, and then
LINK1 led will be on.
<Note>
Do keep module default settings in this process.
Meaning of LEDs
POWER “on” means normal power supply, “off” means power supply failure
GPRS
“on” means attached, “off” means attach failure
LINK1
“on” means socket A has connected to server, “off” means not connect
3. Wait for LINKA led on, send data to module via serial port.
For example, if you send “http://www.usr.cn”, at the same time, the DATA led will be on for a while.
Then, you will get “http://www.usr.cn” in the receiving window from our test server.
