  • Page 26: Serial Configuration Mode

    There are two different ways to enter ISP mode. One is to apply LOW signal to ISP pin for over 1 second, the other is to apply power on CSE-M53G while ISP pin is connected to GND. Entering the ISP mode is used for two purposes in the below chapters(4.6.1/4.6.2).

  • Page 27: Communication Modes

    Communication Modes 5.1 TCP Server In this mode, CSE-M53G functions as a TCP server. CSE-M53G listens to a TCP connection from remote host. Once a host tries to connect to CSE-M53G, its responses that request. After the connection is established, CSE-M53G converts the raw data from the serial port to TCP/IP data and sends them to the network and vice versa.
