The network debugging assistant is a very suitable TCP/UDP debugging tool. Users of the network debugging assistant may not know the detailed operations of how to test the GPRS communication of the pos machine. So today I will explain the steps of using the network debugging assistant to test the GPRS communication of the pos machine. Oh, I hope it helps everyone.

First, configure the port corresponding to the computer host on the router and log in to the router. Here is the method of configuring the port on the Feiyustar router. In the advanced options - port mapping - add the port corresponding to the host.

After setting the parameters, click Connect. At this time, the network assistant has been started.

Log in to the router, select System Status->Network Interface, and query the IP address connected to the router

The POS machine is turned on, and the IP is set to the router IP in the GPRS settings, and the port is the port configured on the router. It is consistent with the port on the network debug assistant

After all parameters are configured, communication can be started. The POS machine makes a communication connection. The network debugging assistant receives the message sent by the POS machine. Enter the message on the network debugging assistant and click Send. The POS machine receives the message and a prompt pops up. interface, the whole process is complete.

Here are you to share the network debug assistant test POS machine GPRS communication method. Friends in need, please come and read this article!
