MAN #650519:B
Initial setup
Once the module is mounted securely and wired, there are a few internal tasks the GPS module will complete on its own.
First, the module needs time to acquire and track the satellites. This typically won’t work inside a steel building, so have
the vehicle outside to speed up the process. There is a dot in the upper right of the display that will be on steady or on
and flashing any time the key is on. The dot in the top center of the display will be on steady once it has gotten a GPS
satellite fix. The unit won’t operate until it gets a fix and this may take 1 – 15 minutes depending on various things. This
delay is only for the initial GPS fix. After this it will typically begin operating within a few seconds of turning the key on.
The second step is to let the internal acceleration sensor learn how it is mounted in the vehicle. You can mount it
securely in any position you want. When you are sitting still it learns which way is up. In order to learn which way is the
front of the vehicle you need to accelerate or decelerate on a straight stretch of road. Accelerate or decelerate for at least
2.5 seconds and make sure your speed changes by at least 10 mph. This procedure only needs to be done initially and
doesn’t need to be repeated unless you move the module to a different mounting location.
If you move it to a new mounting location or a different vehicle, enter the setup menu and select the
rst
option to speed
up learning the new mounting position.
Dakota Digital display data usage
The speed outputs can each be used in place of a separate transmission connection to the gauge control unit. The clock
is based on the accurate GPS time and only the hours need to be set to match it to your time zone. The compass
requires no setup or calibration for the vehicle and is accurate any time the vehicle is moving. The altimeter is calculated
from the GPS position data to give your current elevation. Each of these can be individually turned on or off.
The compass and altimeter may not display correctly unless the gauge control has the following firmware version or
higher:
VFD3:
SE46
VFD3X:
SE55
VHX:
C VX04.009
(control box firmware must end in “.009” or higher)
D V***.006
(display firmware must end in “.006” or higher)
The compass, clock, and altimeter will be displayed in the message center.
Using speed from the GPS-50-2 without a BIM-01-x connected
•
Make sure the BIM units are all connected to the gauge control box with the supplied BIM power/data cables.
•
Hold the SW1 switch from the gauge system control box while turning the key on. The message display should
show SETUP.
•
Release SW1. The message display should show SPEED.
•
Press and hold SW1. The message display should show SENDER. Release SW1.
•
Press and release SW1 until BUS is displayed.
•
Press and release SW1 until DONE is displayed.
•
Turn the key off.
•
Next, press and hold the switch on the GPS-50-2 while turning the key on. The GPS-50-2 display should show
the current software revision.
•
Release the switch. The display should show “
