FTB-1v2 and FTB-1v2 Pro 451
Properties
For example, if you receive this response (here,
values are expressed in decimal instead of binary
for easier readability):
# 2 1 3 7 5 8 9 2 ...
The byte that immediately follows the # contains
2, which means that you have to read the two
following bytes to know the length (in bytes) of
the retrieved data. The bytes indicate 1 and 3.
The length will then be 13 bytes. The actual
response will begin at byte number 5, in this
case.
Possible error(s) Timeout: This error will occur if the allowed
delay has expired before the preceding Write
operation could send a response to the output
queue. For information on timeout setting, see
Initialize on page 451.
QueryUnterminated: This error will occur if the
output queue is empty (for example, no query
has been made previously).
