Setting Description Details
Z4 1-Loop Pulsed Emulates a single-
loop system; only
indicates vehicle
presence—no
speed or duration
information.
Use this when you’re
using the SmartSensor
HD in a system that
was designed for
single inductive loops
and all you need is
vehicle presence;
this may be useful for
doing counts.
Z4 1-Loop Speed Emulates a single-
loop system; has a set
vehicle length of 15
feet, so the emphasis
is on speed.
Use this when you’re
using the SmartSensor
HD in a system that
was designed for
single inductive loops
and you are focused
on speeds.
Interval data only
HD (legacy) Emulates the interval
data from older
versions of this
sensor; it’s similar to
the HD format but
lacks speed bins and
direction bins, and
has fewer length bins.
Use this when
you’re using a newer
SmartSensor HD in
a system that was
designed for an older
SmartSensor HD.
RTMS Emulates RTMS
format.
Use this when you’re
using the SmartSensor
HD in a system that
was designed for an
RTMS X3.
Presence data only
Z4 Presence Outputs presence
data in the Z4 format.
Use this if your
application needs
the immediacy of
presence data,
and you need it to
communicate with
other Wavetronix
devices such as
contact closure cards.
Note.
Presence data
has lower latency
than event data, so
it may be useful for
applications that
need the quickest
possible data
reporting. However,
the trade-off is
lower accuracy. For
most applications,
event data is the
best choice.
