I tend to operate during times of the day that have poor satellite coverage. How can I plan around this?
Trimble provides a satellite coverage planning tool at www.trimble.com/GNSSPlanningOnline. Locate your location on the map, and this tool will indicate the number of satellites visible during the selected timeframe.
What cable is needed to export GPS from a 162/252/262/372 GPS receiver to a 3rd-party device?
There is a need for multiple GPS outputs from the 162, 252, 262, and 372 GPS receivers.
This is especially common when exporting GPS to a secondary control or logging system on an AccuGuide-equipped vehicle. This condition is found most often on tractors running AFS AccuGuide autoguidance and pulling a planter that runs row clutches via a second control system (not via the AFS Pro 600 or AFS Pro 700).
Use CNH part number ZTN55224 to export GPS signals from a 162, 252, 262, or 372 receiver to a 3rd-party device. This cable is designed to allow Port C to be utilized when Ports A and B are already in use (for example, when using RTK and the Joey radio). If Port A or Port B is unused, you may use cable 87298129 instead of ZTN55224.
On vehicles equipped with AFS AccuGuide, it is also possible to export a corrected GPS position directly from the NavII or NavIII controller to a 3rd-party device. Use cable 87298129, or, if the cable is completely inside the cab, use 380002422. Configure the GPS export via the Toolbox > NAV screen in the AFS Pro 700.
How do I order or renew an OmniSTAR differential signal subscription?
GPS differential correction signal (DGPS) subscriptions are now ordered and renewed directly though OmniSTAR Inc. Customer Service.
You may contact OmniSTAR Customer Service at 1-888-OMNISTAR, or contact your local Case IH dealer for assistance.
How do I need to configure my receiver's serial port to communicate with the AFS Pro 600 or AFS Pro 700?
The AFS Pro 600 and AFS Pro 700 require incoming GPS in the following format:
- Communication protocol: NMEA
- Baud rate: 4800 - 38400bps (38400 is preferred)
- Data bits: 8
- Parity: None
- Stop bits: 1
- Hertz rate 1 hz or 5 hz
- NMEA strings: Only GGA is required. GSV can be used to enable the constellation map in Diagnostics > GPS2.
