About the GPS receiver
The DGPS receiver is used to determine the exact position of a vehicle during field
work.
Meaning of the LED lights
The DGPS receiver has a status LED, which shows the quality of the connection:
▪ Red: DGPS receiver is connected to the terminal, but is unable to receive a GPS
signal.
▪ Orange: DGPS receiver can receive GPS signals, but has no differential signal.
Its accuracy is very low, and cannot be used for precision farming.
▪ Green: DGPS receiver can receive GPS signals and the differential signal.

◦ Never place your fingers between the magnetic pedestal of the GPS receiver
and a metal surface.
◦ Hold the GPS receiver firmly in your hands, but do not place your fingers under
the magnetic pedestal.
NOTICE
The GPS receiver needs an open view of the sky.
◦ Mount the GPS receiver on the roof of the vehicle cab.
◦ Avoid shadowing the GPS receiver's view of the sky.

Potential damage to the terminal from a short-circuit.
◦ Switch the terminal off before plugging in or removing the connector.
Procedure
3.2
Procedure
3.3
1. Find a suitable place on the vehicle roof. This place should be as far to the front
as possible and in the middle of the vehicle.
2. Use alcohol to clean the place where you will mount the DGPS receiver.
3. Stick the provided 3M double-sided adhesive tape onto the clean surface.
4. Clean the provided metal plate.
5. Remove the protective paper from the 3M adhesive plate and bond the metal
plate onto this.
6. Screw the magnetic pedestal onto the DGPS receiver.
7. Place the DGPS receiver with the magnetic pedestal onto the metal plate.
Connecting the GPS receiver to a terminal
This is how you connect the DGPS receiver to a terminal:
1. Switch off the terminal.
2. Guide the cable of the GPS receiver into the vehicle cab.
3. Find the appropriate RS232 connection on the terminal. Refer to the operating
instructions for the terminal to find out which connection this is. For the majority
of terminals from Müller-Elektronik, this is going to be port C.
4. During initial start-up it can take approx. 30 minutes until the DGPS receiver has
reception. At subsequent start-ups it will only take approx. 1-2 minutes.
Configuring the GPS receiver
The DGPS receiver can be configured differently for various terminals.
To find out about which parameters you must configure and how, read the operating
instructions for the terminal and the applications which will use the DGPS receiver.
