Anbau- und Bedienungsanleitung - Connecting the GPS Receiver to the terminal

Connecting the GPS Receiver to the terminal

Preconditions

Each GPS receiver which is connected to the terminal must fulfil the conditions in the table below. GPS receivers which can be purchased from Müller Elektronik fulfil these conditions.

Technical requirements for using the DGPS Receiver

Operating voltage:	Supply voltage of the terminal – 1.5 V
Current consumption	Maximum 200 mA (at 70°C)
GPS standard	NMEA 0183
Refresh rates and signals	5 Hz (GPGGA, GPVTG)
Refresh rates and signals	1 Hz (GPGSA, GPZDA)
Transmission rate	19200 baud
Data bits	8
Parity	no
Stop bits	1
Flow control	none

		CAUTION
	Damage to the equipment caused by short circuit Pin 4 of port C is live. The voltage depends on the operating voltage of the terminal and is used to supply the DGPS Receiver from Müller Elektronik. Other GPS Receivers may suffer damage if connected to this port. Before connecting a different GPS Receiver: 1. Check what voltage the terminal is connected to (12 V or 24 V). 2. Check the pin assignment of the GPS Receiver. 3. Check the allowable voltage for the GPS Receiver. 4. Compare the terminal voltage to the allowable voltage for the GPS Receiver. 5. Compare the pin assignment. 6. Only connect the GPS Receiver to the terminal, if the voltage range and pin assignment of both devices don't differ from each other.

During initial start-up it can take approx. 30 minutes until the GPS Receiver has reception. At subsequent start-ups it will only take approx. 1-2 minutes.

Procedure

þ: The GPS receiver is mounted on the roof of the tractor.

þ: You have activated a suitable driver.

1.: - Switch off the terminal.

2.: Guide the connection cable from the GPS receiver into the cab.

3.: CAUTION! Ensure that the cable is not laid across sharp edges or at risk of becoming bent. Lay the cable in a place where nobody can trip over it.

4.: Connect the connecting cable of the GPS receiver to port C on the terminal.
