To specify the time in seconds that a configured queue unit input
must be inactive before its output which was previously active is
cleared.
The count weighting factor for each count unit is the number of
internal counts required to cause the reply bit to change state. The
data is selected using the table below. The value used depends on
the maximum vehicle flow rate at each count site, generally a
weighting factor of approximately twice the maximum flow will be
required.

The occupancy weighting factor is the number of internal counts
required to cause the reply bit to change state. The value is
selected using the table above (see GCF command). The internal
count rate is 25 Hz for 100% occupancy so a weighting factor of 32
is normally used, giving a change of state every 1.28 seconds.
