Troubleshooting GPS-based
Seeding with SiteMate
1. No Rx rate appears on SiteMate
• has field been selected? Select VRT file (see
SiteMate Settings, Step 5)
• 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 rec-
ipe 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 103, page 80)
• double-check all cable connections
• check Nominal rates on both the SiteMate
(SiteMate Settings, Step 4), and on the GP
Controller Console (GP Settings, Step 2)
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 4), and on the GP
Controller Console (GP Settings, Step 2)
These must be set to the same number.
• Re-check GP calibration number, with meter-
ing wheel and row spacing.
• The recipe rates from SiteMate are in 4% in-
crements. If the two rates are within this 4%
range, the units are operating normally.
• Check the Conversion number (SiteMate Set-
tings, 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 SiteM-
ate Settings, Step 4 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 meter-
ing wheel and row spacing.
• Re-check planter monitor settings: calibration
number, row spacing, number of rows, swath
width, seed, etc.
• On small seeds and/or high rates, if population
monitor consistently indicates a lower popula-
tion than the GP Controller Console, contact
monitor manufacturer for performance specs
for that application.
6. 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 Connec-
tions-check GPS settings in Configure/Set-
tings/GPS settings/COM (typically COM1,
4800 Baud, 8 data bits, Parity None, and Stop
Bits 1)
