com.wiegand.<n>.physical.tpw
This variable is used to set or to interrogate the pulse width time (Tpw),
where the pulse width time is specified in microseconds. Values of 40 to
250 µs are valid. The default value is 50 µs. The variable will return a value
in the range 40 to 250 µs. n = 1 to 4.
Note that the WIM has a granularity of 5 µs and pulse_width_times will be
truncated to the nearest 5 µs.
Also note that these are nominal time values for 470Ω pull-up loads on the
Wiegand outputs. The pulse width time lengthens for higher values of pull-
ups, and shortens for lower values. This phenomenon is caused by Miller
capacitance on the loads. The 5 µs granularity on the pulse_width_time can
be used to tailor the pulse width to the required value.
