GPS Troubleshooting
Troubleshooting GPS with SiteMate
1. No Rx rate appears on SiteMate
• Has field been selected? Select VRT file (see
SiteMate Settings, step 7, page 57)
• Check recipe to verify that it is valid by viewing
Attributes for each zone in SiteMate
• If recipe calls for zero rate as the default, do you
have GPS signal, or are you outside of field?
2. Rx rate appears on SiteMate, but no Applied Rate.
• Make sure “Go” button on SiteMate is pressed.
(button should read “Stop” when recipe is being
sent to GP Console)
• You must be planting in order for Applied Rate to
appear.
3. Rx rate appears on SiteMate but not on GP
Controller Console.
• Make sure GP Controller Console is set to VR
Mode (see Figure 40 on page 41).
• Double-check all cable connections
• Check Nominal rates on both the SiteMate
(SiteMate Settings, step 6, page 57), and on the
GP Controller Console (GP Settings, step 3,
page 58) These must be set to the same number.
4. Rates on GP Controller Console and on SiteMate do
not match.
• Check Nominal rates on both the SiteMate
(SiteMate Settings, step 6, page 57), and on the
GP Controller Console (GP Settings, step 3,
page 58) These must be set to the same number.
• Re-check GP calibration number, with metering
wheel and row spacing.
• The recipe rates from SiteMate are in 4%
increments. If the two rates are within this 4%
range, the units are operating normally.
• Check the Conversion number (SiteMate Settings,
Step 2). If the recipe requires a target conversion
number, i.e. the recipe is for 25 which means
25,000 seeds/acre, the target conversion number
will be 1000. In this case the Nominal Rate in
SiteMate and the GP Console should be near
25,000. See SiteMate Settings, step 6, page 57
for calculating Nominal Rate.
5. Population Monitor rate does not match GP
Controller Console.
• Make certain that SiteMate and GP Controller
Console agree. If not, see Troubleshooting step 4.
• Re-check GP calibration number, with metering
wheel and row spacing.
• Re-check planter monitor settings: calibration
number, row spacing, number of rows, swath
width, seed, etc.
• GPS signal is not being received by SiteMate:
• Verify that GPS serial port (which is also the
docking port) is not set to PC connection only
(Start/Settings/Communications/PC
Connections-check GPS settings in
Configure/Settings/GPS settings/COM (typically
COM1, 4800 Baud, 8 data bits, Parity None, and
Stop Bits 1)
