Outback S2 User manual
Overview
The Outback S2TM includes a ground speed interface (GSI)
port on the back of the console. The internal GSI module, as
factory installed, is pre-activated with a one-time
subscription code. The GSI module converts the GPS
velocity signal of the Outback S2TM to a doppler radar
compatible pulse output. This output may be used as the
ground speed input to any agricultural 3rd-party
monitor/controller designed for use with a DICKEY-john
RVS-II radar gun (or equivalent).
Installation - General Application
1. First install the Outback S2TM and any other Outback
products as normal. Refer to the respective products owner’s
manual for proper installation.
2. Locate the GSI cable, P/N: 051-0128, included in this kit.
3. Connect the smaller 6 pin connector end of the GSI cable
to the GSI port on the rear panel of the Outback S2TM
console. Twist connector firmly until it snaps into place.
4. Connect the larger 4 pin connector end of the GSI cable to
the rate controller speed input. An adapter cable may be
required. See the reverse side of this page for controller
specific instructions.
5. Power up the rate controller, the Outback S2TM, and any
other Outback consoles. Once the Outback S2TM has acquired
GPS (or DGPS), and the vehicle is moving between 1 MPH
and 60 MPH, the internal GSI module will send output
pulses to the rate controller.
6. It is necessary to calibrate the rate controller speed input
signal. Refer to the owner’s manual provided with the rate
controller for proper speed input calibration.

Pulse Output Signal Specifications
The GSI pulse output signal and connector is equivalent to a
DICKEY-john RVS II radar gun. The output is a square wave
(Ground to +12 VDC Battery) with a frequency proportional to
GPS estimated ground speed, 44.21 Hz per MPH speed.
Minimum ground speed is 1 MPH, below which the output
frequency is zero. Maximum ground speed is 60 MPH, above
which the output frequency is zero.
The pulse output connector is a 4-pin AMP #206429-1:
Pin 1 = Ground
Pin 2 = Pulse Output Signal
Pin 3 = +12 VDC Battery
Pin 4 = No Connection
The mating cable connector is a 4-pin AMP #206430-2.

Installation - Raven SCS 440 / 450 / 700
This kit includes a special adapter cable to connect the GSI pulse
output to a Raven SCS 440, 450, or 700 controller, PGM. E or
later.
1. Locate the Raven / GSI interface cable. Connect the 3 pin
connector to the speed input plug of the rate controller console.
Connect the 4 pin connector to the GSI “PULSE OUT” connector.
Connect the single red wire to the orange, +12 VDC switched,
wire on the Raven console cable.
2. Program the Raven console for ground speed input type SP2
(radar sensor).
3. Enter an initial SPEED CAL value of 838.
4. Perform a speed calibration test and adjust the initial SPEED
CAL value as required. Refer to the Raven operator’s manual for
proper calibration procedure.
