WAVECONTROL SMP2, User Manual

Page: 89 / 97

Limitations and Timeout
The XML commands from the PC to the SMP2 can be up to 32768 bytes. The
SMP2 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
SMP2 will not send any response.
When connecting the USB to the computer, the SMP2 will interrupt listening the
fibre port.
Example of Commands
These examples have been automatically generated by the software SMP2
and should be sent unformatted (ie no spaces and line breaks between tags).
