This Quick Start provides basic instructions for getting your RAC Geo installed and operating. For more de-
tailed instructions, the complete User's Manual can be downloaded at www.jamartech.com/manuals.
What is the RAC Geo II?
The JAMAR Technologies Road Analysis Computer
(RAC) Geo II is an accurate, easy-to-use distance measur-
ing instrument (DMI) that incorporates GPS technology.
The RAC Geo II has been designed with features to pro-
vide you with a versatile and functional instrument that
can be learned in a very short time. This cost-effective
unit saves time & money by allowing personnel to measure distance, accurate up to 1 foot per mile, while recording GPS coordinates
of roadway features.
How does it work?
The RAC Geo II has an on-board GPS receiver built into the unit. Once it locks onto the GPS satellites, it can track movement. Power
is provided by a 12V auto adapter, which makes the unit completely portable from vehicle to vehicle. (Power can also come from
any existing DMI power wiring if you already have this.)
While the on-board GPS receiver will track distance, we recommend the use of the external GPS antenna for the best accuracy. This
screws into the top of the Geo II and comes with the unit.
Accuracy using GPS-based distance measuring is approximately 1 foot per 1000 feet. In addition to distance measuring, the RAC
Geo II also has the unique ability to track and store GPS coordinates using the on-board GPS receiver. The GPS coordinates of road
features (intersections, bridges, signs, guardrails, etc.) can then either be internally stored for download to the RACPro software, or
read directly off the RAC's display.
Installing the RAC Instrument
The compact case design of the RAC Geo allows mounting of it in a number of convenient loca-
tions. Popular locations include on the front of the dashboard, above or below the dashboard,
or on the windshield using the optional windshield mounting bracket. Wherever you decide to
mount the instrument, remember it should be within easy reach and the display should be visible
without obstructions.
It is most common to mount the RAC to the front of the dashboard using the Velcro provided.
Two plastic 'L' brackets are also provided to facilitate mounting to the top of the dashboard if that
is your preferred location. For best results, attach the 'L' bracket so that the bottom of the 'L' is facing away from the RAC as shown
in the figure here.
Using the two 'L' brackets allows you to compensate for curved dashboards even
if it requires the RAC to be mounted on a left or right slope.
Note: While the RAC Geo II is designed to withstand very high temperatures, we
recommend disconnecting the RAC and storing it in the glove box or below the
dash if the vehicle will be left for long periods of time in direct sunlight and high
temperatures.
