    IP correctly. Otherwise, communication will not be possible. PD9 work as TCP Client, It connects to the target IP/Port automatically,will not accept other connection request. When 302 is used as the TCP Client, it is recommended to set the local port number of 302 to 0. In this way, 302 can access the server with a random port number, which can solve the problem of reconnection failure caused by the server determining that the connection state is abnormal.

    4.6.3. The number of the client connected Then the PD9 work in the TCP server mode, the max number of client to connect is 8, default is 4,the max number can be configuring as you want, which is be convenient for use. When the the number connecting clients more than 4, we should control the total data flow in 2.5KB/s if we need to send and receive meanwhile(not more than 200 bite/s).

  • Page 27: Serial Port Packaging Mechanism

    Flow Calculation When PD9 receives data from network and then send to serial port, as the limit of serial port speed, user have to control the flow, if not the problem of data overflow on serial port side will occur. So data flow is required to calculated when sending data from network to serial port.
