3.4.6 SERIAL COMMAND HANDLING

3.4.6.1 Command Time Out

The 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.

3.4.6.2 Buffer Flushing

The DSP will flush the incoming serial data buffer every time an
STX is received. This provides a mechanism to clear the receive
buffer of partial or corrupt messages.

3.4.6.3 Handshaking

The only handshaking implemented on the host interface, is built in
to the implementation of this protocol. That is, the host must initiate
all communications. If the supply receives a program command, an
acknowledge message is sent back to the host via the “;” message.
If the host does not receive an acknowledge within the time out
window, the host should consider the message lost or the device
off-line.

Similarly, if the supply receives a request command, the requested
data is sent back to the host. If the host does not receive the
requested data within the time out window, the host should
consider the message lost or the device off-line.

This essentially uses the full-duplex channel in a half-duplex
communication mode.
