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 Con-
troller Console:
• Make sure GP Controller Console is set to VR
Mode (see Figure 29, page 15).
• 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 cup setting
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 4 for
calculating Nominal Rate).
5. Population Monitor rate does not match GP Con-
troller Console:
• Make certain that SiteMate and GP Controller Con-
sole agree. If not, see Troubleshooting step 4
above.
• Re-check GP calibration number, with cup setting
and row spacing.
• Re-check 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 population
than the GP Controller Console, contact monitor
manufacturer for performance specs for that appli-
cation.
6. GPS signal is not being received by SiteMate:
• Verify that GPS serial port (which is also the dock-
ing port) is not set to PC connection only (Start/Set-
tings/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).
• Click Data tab to view GPS details.
