cycle can begin as soon as the old one is either properly executed or is
discarded for any reason.
The signals required for a pulse depend upon the repeater access mode. If
the repeater is in Carrier Access Mode, then the controller will count pulses
at the COR input. If the repeater is in AND-PL Access Mode, then the
controller will count pulses that are made up of both COR and PL signals.
Execute macro "123" when four pulses are received. Each pulse must be
1/4 second long, and all four pulses must occur within 5 seconds. The
commands are:
(PW) 26 17 0123 *, which assigns macro "123"
(PW) 47 0 4 0025 0500 *, which assigns parameters
NOTE: "0025" x 10 ms = 250 ms = 1/4 second, and "0500" x 10 ms = 5000
ms = 5 seconds.
The controller calculates that 4 pulses at 1/4 second each equals one
second pulse time. The maximum dead zone is then 4 seconds, and no
pulse can exceed 4 1/4 seconds. The window will close if any of these
timers are exceeded.
The controller will respond with an error if the pulse count, multiplied by the
width, exceeds the window time.
