THEORY OF OPERATION
The 3210 Series Timers are completely
self-contained race timing systems made with
the latest technology CMOS circuit components
to provide a highly accurate timing solution. The
system contains an internal quartz crystal clock to
maintain time accuracy and display of race results
to one thousandth of a second.
Power is supplied to the timer console and
track sensor components of the 3210 by the
12VDC automotive battery connected to the
RED and BLACK alligator clips, cigarette lighter
adapter, or an AC adapter. An absolute minimum
of 11.0VDC is required for reliable operation of
the system. Under normal conditions, charged
batteries will operate for several days of racing
without requiring a recharge.
The Beam Emitters and Track Sensors
operate on invisible (to the unaided human eye)
Infra Red (IR) light. The coded light frequencies
are constantly received by the Track Sensors until
a car interrupts reception ('breaks' the beam).
Connections to the console can be hard wired or
wirelessly connected via T-Link track electronics.
The IR Beam Emitter to Track Sensor
transmission operates on Line-of-Sight principles.
This makes alignment of these units critical. Tips
are provided to aid alignment on surfaces that
are other than ideal. These units will operate
over a wide range of conditions but should not be
operated beyond the specification parameters (less
than 4 ft or more than 50 ft).
Once the system is properly set up and
aligned on the racing surface, the timer console
will 'monitor' the track sensors each time a run
is made.
PACKAGE COMPONENTS
The Timer MB is sold in hard wire versions
(3210D), wireless versions (3210D-W) and with
slower response IR beams (3210DS and 3210DS-
W with '58' beams).

NOTE: Sensors and Emitters work in pairs;
5040 emitters work with 5140 sensors and slow
response 5058 emitters work with 5158 sensors.
Do not mix sensor pairings!
POWER REQUIREMENTS
You will need these additional items to
operate your 3210 Series timing system:
1 - 12VDC auto battery for Console
8 - 'AA' batteries for Beam Emitters
NOTE: Operating the timer from a battery
connected to a charger or running car engine will
result in an over voltage condition and damage
the timer.
