  • Page 49: Serial Port Packaging Mechanism

    Flow Calculation When USR-N540 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.

  • Page 50: Synchronous Baud Rate (Rfc2217)

    ① If there is no overflow, m bytes data must be transmitted within n seconds, then the transmitting time of M bytes data: If n >2T, then data will not overflow, USR-N540 can work normally. Just need keep n>T under baud rate 9600. 3.7.10. Synchronous baud rate (RFC2217) For encryption during data transmission, devices change data bytes, baud rate, parity and so on.

    2. When serial parameter changes is needed, it send RFC 2217 packet. USR-N540 receive the command from network and revise serial parameter accordingly, do not transmit the RFC2217 command transparently. 3.7.11. Keep-Alive When USR-N540’s network is abnormal, it can judge the status in time and disconnect. And connect to server once network recovers. 3.7.12.
