6.7 Communication
6.7.1 Connection between the Correlator and the sensors
Short range radio is used for communication between the Correlator and the sensors
(Power transmitters and Multi sensors).
Analogue short range radio is used for Online measurements. Digital short range radio
is used for Offline measurements. Therefore, the Correlator is equipped with two radio
antennas.
Antenna 1 ... Digital radio
Antenna 2 ... Analogue radio
6.7.2 Connection between the Correlator and the computer
The included VK 77 connection cable is used to connect the Correlator to a PC/laptop.
This connection is needed for
• correlation data transfer to the computer
• firmware update file transfer to the Correlator
To connect the Correlator to a computer, proceed as follows:
Step Description
1
In the main menu, tap the button .
2 In the displayed menu, tap the Connect Correlator to PC button.
3
Establish the cable connection.
Connect the round plug of the cable to the USB/GPS socket of the Correlator.
Observe the markings on the plug and socket. You must feel the plug engage.
4 Tap the Connect button on the Correlator.
Result: The connection is established. The Correlator is automatically detected
by the computer as a mass storage device. As soon as the Connected message
on the Correlator’s screen appears, data can be transferred.
If no connection is made, check the cable connection again. If necessary, disconnect
the Correlator from the computer, restart it or perform a reset, and follow steps 1 to 4
once again.
To end the connection, select the Disconnect button on the Correlator. As soon as the
Disconnected message appears, the connection cable can be removed.
6.8 Hardware reset
If the Correlator stops responding to inputs (neither from touch screen nor from rotary
encoder or pushbuttons), a hardware reset can be performed.
Hold down the rotary encoder and the ESC pushbutton at the same time for
about one second. The Correlator restarts automatically. This usually rectifies the
malfunction.
If the device still malfunctions after resetting the device, try the following: Hold down the
rotary encoder and the ESC pushbutton at the same time for about 3 seconds. The
Correlator switches off. Wait about a minute before switching the Correlator back on.
The Correlator should now function correctly again.
