bbbb = low alarm trip level 0 - 1023, at or below which a
housekeeping alarm is raised. cccc = high alarm trip level 0 -
1023, at or above which a housekeeping alarm is raised.
dd = low dwell time, ee = high dwell time, value 1 -255 = no. of
10ms periods, 0 = no dwell time (react immediately)

- - Up or Down: byte aa = ASCII + (decimal 43) to increase channel
number, ASCII - (decimal 45) to reduce channel number.
Channel No.: byte ff contains binary value 0 to 99, the number of
the channel to go to in the direction indicated. (+0 and -0 are
identical)
Channel change will occur after the acknowledge message has
been sent.
