Product Overview
The GPS-50-2 can be used to provide an accurate speedometer signal with a Dakota Digital instrument system as well as
many factory and aftermarket speedometers.
•
Has built in GPS antenna for compact design.
•
When coupled with a Dakota Digital system with a BIM cable, the unit can provide speed, compass, clock,
altimeter, and optional air temp functions.
•
There are two interface (I/O) ports on the module for use with a Dakota Digital instrument system; either one can
be connected to the control box or a BIM-series module, allowing several units to be daisy chained together.
•
The GPS-50-2 cannot be connected to any BIM-01-2 module.
•
Additionally, there are two speedometer outputs for standard speedometers plus a dedicated cruise control speed
output.
o
The speed output values cannot be fine-tuned and represent commonly seen vehicle speed
signals.
o
Fine tuning speeds for non-Dakota Digital gauges will require the SGI-100BT also.
•
The optional SEN-15-1 outside air temperature sensor can be connected when a Dakota Digital instrument
system is connected to provide an outside air temperature reading.
•
The optional remote antenna 600041, (mounted on top of the dash), can enhance signal reception if the module is
hidden under the dash, and improves cruise control operation.
•
Cruise speed output can operate some OEM cruise modules, the CRS-3000 cruise module, and most aftermarket
cruise modules.
The GPS speed signal can be momentarily incorrect due to interference from overpasses, tunnels, and nearby structures.
To avoid this problem, the system stabilizes the speedometer reading by constantly comparing it with an internal
acceleration sensor.
When the key is off, the system goes into a very low power standby mode and only occasionally wakes up to update GPS
readings so that it is ready to start operating as soon as the key is turned on.
If using a BIM-01-2 series with a Dakota Digital dash, the GPS-50-2 must be wired as a
standalone, (page 5) without using the BIM cable.
Display Legend
The dots in the LED display can tell us if the GPS-50-2 is seeking satellites or has acquired connection.
The upper left dot indicates several operations:
▪
Slow flashing dot, key off
– trying to connect, or stay connected, to satellites.
▪
Slow flashing dot, key on
– trying to connect to satellites.
▪
Solid dot
– contact made. Good if used as a standalone GPS unit without a BIM cable
o
If using a BIM cable to a dash system, no communication with dash, (check BIM cable)
▪
Steady flashing dot
– acquired satellite connection and communicating with dash system with BIM cable
Upper right dot
– comes on solid only with key on, indicating at least four satellites are acquired.
Lower right dot
– activates when the accelerator takes over when satellite signal is temporally lost
