Satspeed 2 Interface
Description
The Satspeed 2 Interface converts GPS data to radar compatible speed pulse .
The Satspeed 2 interface will accept a standard NMEA GGA and VTG message from a GPS receiver and will
convert this message to a pulse output proportional to forward speed. The pulse output is compatible with the
output of most industry standard radar speed sensors. The RS232 output from a GPS receiver can be shared
between the Satspeed 2 interface and any other equipment using the GPS ( e.g. a guidance system)
Advantages
True ‘speed over ground’ calculated from up to 12 GPS satellites
Sensor and cabling installed away from moving parts and out of vulnerable areas.
Not influenced by wheel slip, wheel size, tyre pressures or vehicle load.
Not influenced by pitch or yaw of vehicle
Not influenced by moving crops
Sensor positioning / alignment not critical
Operates with any GPS receiver that outputs NMEA messages via serial RS232 port.
Does not need differential correction but accuracy is directly related to GPS receiver quality.
Specification
Power supply 10-30V dc
Output: npn open collector pulse.
S/SR/385-2-001/004 :- 35.60Hz/ km/hr = 128.16 pulses per metre = 57.42 Hz/mile/hr.
S/SR/385-2-002 :- 36.60Hz/ km/hr = 131.78 pulses per metre = 59.00 Hz/mile/hr.

[1] Alternative to DickeyJohn "iSpeed Interface" (uses the same SSF setting).
[2] If the speed reading is found to be half what it should be, the likely reason is because certain (earlier specification)
instruments require a SSF expressed as metres per 2pulses.
Satspeed 2 Operation
Limitation
This unit should not be fitted in situations where speed measurement <0.5km/hr isrequired,or there isconsistent
poor quality GPS reception.
On initial power-up, it may take up to 5 minutes depending on the reception, to output a ground speed signal.
When used on a regular basis (daily or weekly), the startup time may be 1-2 minutes.
Bear in mind also, that the ground speed signal may be temporarily lost depending on the terrain and ground
cover (e.g. under or behind trees), and that this will be more prevalent in areas with weaker reception from a
limited no. of satellites.
Operation
The unit will automatically find the baud rate and depending on GPS reception status, provide a forward speed
signal on power up.
NOTE: The forward speed reading will default to zero below 0.5km/hr.

On Off Power but no GPS signal (No forward speed reading)
On Flash* Power + Standalone GPS (should result in forward speed reading)
On On Power + Differential GPS (optimal performance)

General Installation Guidelines for the GPS Receiver
The GPS receiver has a magnetic base. A double-side adhesive foam pad and metal mounting plate isprovided in
the kit, to enable magnetic mounting onto non-magnetic surfaces.
Mount the antenna to give an unobstructed hemisphere of sky. This will ensure that GPS satellites are not
masked by parts of the vehicle, potentially reducing system performance.
Wherever possible, avoid drilling holes in the roof to avoid both water ingress and possibly wiring / air
conditioning equipment etc. If drilling is unavoidable, use silicone sealant around fixing and cable entry points.
Mount the antenna as far as possible from any equipment that can cause Electromagnetic Interference
(EMI)including DC motors (e.g. air conditioner), alternator, solenoids, CB radio, power cables, display units, or
other electronics. Excessive EMI will degrade system performance.
TIP: To detect possibly troublesome interference, tune a LW band portable radio off-station. With the aerial laid flat you
can then (hopefully) pick up the direction and source of the interference from the increase in noise. The antenna
can then be repositioned or if necessary, the source of the interference suppressed. If need be, contact RDS for
further advice on suppression methods.
Secure the antenna cable close to the antenna mounting (using cable ties) so that in the event the antenna is
knocked off it's magnetic mounting, it will be restrained and minimise the possibility of further damage.
Mount the antenna in the location for which you desire a position e.g. along the centre line of the vehicle and
as close as possible over the working interface.
NOTE: As this may well be impractical to achieve, the Pro-Series can be programmed via the ‘GENERAL PF SETUP‘
menu with ‘GPS ANTENNA OFFSETS’ to compensate for the difference in position of the antenna from the cutter
bar, spray boom etc (please refer to the "PSi PF Instruments Data Logging and Transfer" manual).
GPS 16 Setup (Standalone GPS input to PSi)
Connect the receiver to the top port on the PSi.
From the "SETUP" menu, select "Port Setup" and set the top port to "GPS Only".
From the "SETUP" menu, select the Speed Sensor Setup screen ( ), and select "NMEA VTG".
From the "General PF Setup" menu, select "GPS Baudrate" and select "19200".
After the initial power-on, allow up to 5 minutes for the receiver to automatically establish its position.
Subsequently the unit should establish position more quickly.
NOTE: The GPS icon at the top of the display indicates the status of the GPS signal.
