2.6. Serial-to-network data conversion

2.6.1. Module as TCP Server

Figure 9

TCP Server

In this mode, the module monitors the specified port and waits for the TCP Client to connect.

After connection, all TCP data is sent directly to the serial port, and the data from the serial port is
sent to all TCP Clients. When the module is used as a TCP Server, it supports up to 5 A TCP Client
connects to the TCP Server

2.6.2. Module as TCP Client

Figure 10

TCP Client

In this mode, the module will actively connect to the specified IP and port. All data sent from

the TCP Server will be sent directly to the serial port, and the data from the serial port will be sent to
