DETECTOR SIMULATION NOTE: For Testing Only
Not a Field Function.
DETECTOR SIMULATION MODE (MM-2-2-6-6-4)
MODE
0 = OFF, 1= Input and system level, 2= System level only
DETECTOR VOLUMES (MM-2-2-6-6-4-PGDN, etc.)

SAT FLOW
PRCNT SAT
*TOTAL VOL
SAT FLOW = Vehicles per hour, max volume when flow unimpeded.
PRCNT SAT = % of above vehicle per hour rate used to compute volume.
*TOTAL VOL = NOT AN ENTRY, computed by LMD based on above % of SAT.
DET PULSE WIDTH & GATE PH’S (MM-2-2-6-6-4-PGDN, etc.)

PULSE MS
GATE PHS
PULSE MS = Duration of each call pulse in Milliseconds (1000 = 1 sec).
GATE PHS RANGE: 1-8 = Phase 1-8, 9-12 = Overlap A-D
Note: Gate phases cause simulation to act like a real stop bar detector. Rather
than just issue calls continuously at a fixed rate, the calls are accumulated when
the gate phase (or overlap) is red, then discharges them after the phase is green.

QUE DET
QUE CNT
QUE DET = Designated DET that is “upstream” from primary DET (column head)
QUE CNT = Number of counts (during red) on QUE DET before it goes steady on
(as if vehicles backed up to it and stopped). Can be used for Adaptive Split.
