Page 31: Communication Modes
Communication Modes TCP Server In this mode CSW-H85F listens to a request of TCP connection from remote hosts. Once a host tries connecting to CSW-H85F, it accepts a connection. After the connection is established, CSW-H85F converts the raw data from the serial port to TCP/IP data and sends it to the network and vice versa. -
