- Page 5 OEM speedometers tend to use SPEED 1. OEM GM cruise controls will like the CRUISE signal when the GPS-50-2 output is set to “4”, while the CRS-2000/3000 modules from Dakota Digital need to be configured for the correct pulses, a square wave signal by turning SW 10 on in the cruise module.

Hold the switch beside the GPS-50-2 display while turning the key on. The display will show the current revision code while this is held. Release the switch. Press and release the switch until “”...
- Page 7 Setup VFD3 / VFD3X Using speed from the GPS-50-2 without a BIM-01-x connected ➢ Connect the GPS-50-2 to the instrument system control box with the supplied BIM power/data cable(s). • Hold SW1 (I) for the VFD3 control box, and turn key on.
- Page 8 Using speed from the GPS-50-2 without a BIM-01-x connected GPS-50-2 BIM speed MUST be enabled. See page 15 for details. ➢ Connect the GPS-50-2 to the instrument system control box with the supplied BIM power/data cable(s). • Hold SW1 (I) for the VHX control box, and turn key on.
- Page 9 GPS-50-2 BIM speed MUST be enabled. See page 15 for details. **HDX/RTX systems can be configured with the Dakota Digital app for Apple and Android devices** • Connect the GPS-50-2 to the instrument system control box with the supplied BIM power/data cables. • Entering setup: HDX –...
- Page 10 To eliminate the “PLEASE SET SPEED” messages, the speed calibration can usually be done with the adjust mode without even driving the car. When the GPS-50-2 is sending out the correct test signal, the speedometer should be reading 60 MPH (96 km/h) or be adjusted to 60 MPH (96 km/h).
- Page 11 Aluminum VFD3, and STR boxes = 8,000 PPM - • Once the GPS-50-2 is set to the correct pulse rate, follow the speed setup in the appropriate system manual(s) for the Adjust Mode, or use the app for HDX and RTX.
- Page 12 Set Speed Output / Test mode to 8,000 PPM - • Once the GPS-50-2 is set to the correct pulse rate, follow the speed setup in the appropriate speedometer manual for the Adjust Mode. o Sometimes the speed may not read 60 MPH (96 km/h), adjust so they match.
- Page 13 Cruise control operation with the GPS-50-2 While a transmission or wheel-based speed signal is ideal for operating a cruise control, the GPS-50-2 can be used when this is not available. If the optional remote antenna is not used, special care must be taken in selecting the mounting location for the GPS-50-2 so that it can get a clear view of the satellites.

- Page 15 Having multiple BIMs like the GPS-50-2 and BIM-19-2 (air pressure) could have a conflict with the Altimeter and Tank pressure, as they both use channel 16. Changing the GPS-50-2 Altimeter ID to 9 or 10 will avoid any conflicts with the five pressure channels in the BIM-19-2.
