REFERENCE GUIDE
(Create a .shp recipe file in FarmWorks Site Pro, SMS
2.0, SSToolbox, or other software that will create a .shp
file, and transfer it to SiteMate.)
SiteMate Settings: (version 8.12)
1. Select CONFIGURE Tab. Select SETTINGS. Se-
lect VARIABLE RATE SETUP. Select NEW. Type in
GP PPC. Under CONTROLLER TYPE, select
Rawson from the scroll-down list. Under COMM
PORT select the port number for the serial card or
flash jacket port.
2. Select MAP tab. Enter DEFAULT rate. This will be
the rate that SiteMate will call for if GPS signal is
lost or you are outside the map area. Note: if GPS
signal is interrupted, or if you are outside the map
area, GP Controller will continue applying rate it
was set at when signal was interrupted, until signal
is regained, or another rate is set manually. If pow-
er to the SiteMate is interrupted, you will need to
restart the recipe to return to VR. In the CONVER-
SION window, enter the conversion rate as follows:
if your recipe (.shp file) is written using the entire
number as the desired rate, i.e. 30,000 seeds/acre
on the recipe means 30,000 seeds/acre is the de-
sired rate, enter both the Map Unit and Controller
Unit as 1. If the recipe is written using a different
number, i.e. 30 on the recipe means a population
of 30,000, then you will need to enter the conver-
sion multiple—in that case 1 Map Unit = 1,000
Controller Units.
3. Under the APP tab, enter the Feed Delay as 3 sec-
onds. Enter the Following Distance (the offset from
the Great Plains meters from the GPS) as follows:
for 15’ and 20’ the distance from the opener to the
hitch pin is 18’; for the 30’ model the distance is
26’; Add the distance from the hitch pin to your
GPS location. Enter the total distance in the Fol-
lowing Distance window. Enter the Swath Width of
the Great Plains unit.
4. Under the CTRL tab, enter the Nominal Rate as
follows: Divide the highest rate on your recipe by
1.6. This is your Nominal rate. For example, if your
highest rate is 200,000 the nominal is 125,000. If
your highest rate is 32, your nominal rate is 20. En-
ter the Step as 4%. Exit VRA Controller Setup by
clicking OK button to save the settings.
5. Under FILE, Open VRT and select the Rx Map
(recipe) for the field. Press the SETUP button and
select the GP PPC controller option that you have
set up using these Settings Instructions.
6. Press GO. The Rx rate window shows the rate that
is being sent to the GP Precision Population Con-
troller. The APPLIED window shows the rate that
the GP Controller is applying.

ally. To return to VR, simply touch the On/VR key to
