Important
Only authorised resellers are allowed to connect the LINK 510 to the digital tachograph.
Make sure that the ground potential of the LINK 510 is identical to the ground potential of
the digital tachograph.
If the tachograph with the covered connectors is sealed, the seal must only be removed
by an authorised tachograph installer.
Using the input IN 1 for idle time reporting
Your LINK 510 can report idle times to WEBFLEET when the engine is running for longer
than five minutes and the vehicle is not moving. This requires configuration in TomTom
WEBFLEET.
The input IN 1 must be connected to a signal indicating the activity of the engine, for
example alternator, engine, etc. The input IN 1 must be active when the engine is running.
For detailed information on how to connect the relevant signal to IN 1, see
Wiring digital
inputs
on page 30.
Using the input IN 1 for changing the logbook mode
Your LINK 510 can report logbook-relevant information to WEBFLEET. Using the input IN
1 you can change the logbook mode between private and business trips. This requires
configuration in TomTom WEBFLEET.
The input IN 1 must be connected to a switch indicating the trip mode. If the input IN 1 is
active the logbook mode is set to Private trip. If no or a low voltage applies to the input IN
1 the logbook mode is set to Business trip. For detailed information on how to connect IN
1, see

Wiring digital inputs
The digital inputs of the LINK 510 operate according to the principle of a voltage detector.
Voltages below 2 Volts are definitively interpreted as being low and voltages higher than
3 Volts are definitively interpreted as being high. The maximum permissible input voltage
is 30 Volts. Low/high switching (increasing input voltage) typically occurs at 2.8 Volts.
High/low switching (decreasing input voltage) typically occurs at 2.1 Volts. The hysteresis
of 0.7 Volts is to avoid rapid switching.
Interference voltages at the digital inputs must remain below 2 Volts. In order to guarantee
this, the input wire of the connecting cable should never remain unconnected. If a digital
input is not being used, the input wire must be connected to ground (GND). To evaluate a
switch, this switch needs to be designed as a change-over switch, switching the digital
