  • Page 57: Serialcommand Handling

    6.0 SERIAL COMMAND HANDLING Command Time OutThe host computer should set a serial time out at approximately 100mS. This allows the DSP to process the incoming message, and transmit a response. The DSP will initiate a reply to incoming messages in approximately 1-2mS, with a worst case of 5mS. Buffer Flushing The DSP will flush the incoming serial data buffer every time an STX is received.
