Limitations and Timeout
The XML commands from the PC to the SMP3 can be up to 32768 bytes. The
SMP3 expects to receive complete commands in less than 3 seconds (counting
from the time of receipt of the first byte); If after this time it does not have a
full and valid response, an error message is sent and discards the
information received so far. If you send a message without the initial “<“ XML
tag, the SMP3 will not send any response.
When connecting the USB to the computer, the SMP3 will interrupt listening the
fibre port.
Example of Commands
These examples have been automatically generated by the software SMP3
and should be sent unformatted (ie no spaces and line breaks between tags).
