GPRS connectivity issues
Blue LED Flashing once per second
A SIM card is present however the unit is unable to initiate communication with
the GPRS network. Initially check all of your GPRS settings (see Page 19). If the
unit still fails to connect first try repowering the unit. If the unit still fails then
you can view the status of connectivity in the digiConnect Current Status
window. The code displayed will show the stage of connection.
You must make sure that the SIM card is not PIN locked and that the contract
allows you to pass Internet data. This is often termed ‘data enabled SIM’.
Blue LED flashing twice per second
Indicates that the device has got onto the Internet but is not registered on a
digicentral server or your digicentral server settings are incorrect.
Blue LED is OFF but the ignition is ON
If the ignition is ON and the Blue LED disappears after a few minutes or more
then try moving the unit away from any other communication sources.
Examples would be things like online weighing, tracking, or onboard
computers. Such devices can interfere with each others signals.
Green LED flashing or OFF
You may not have a connection to CAN2. This could be caused by one of the
following;
1.
Ignition is OFF.
2.
The secondary CAN is not enabled (see page 8).
3.
The Tachograph is too old or of the wrong type (see page 4).
4.
The cabling is faulty. Try another loom.

Troubleshooting Continued
Correct positioning of your digiDL-B or BT
If the Blue LED is flashing and you know that all APN Settings and server
settings are correct then try temporarily moving the digiDL-B / BT away from
other sources towards the confines of the vehicle cabin. In theory, if your
problem is reception then the Blue LED should now go solid.
Now the challenge is to find a position where the digiDL-B or BT is far enough
away from the source of interference.
To assist with positioning of the digiDL-B or BT we produce a 1 metre in line
extension cable with code DDL-TCX. These cables can be daisy-chained to
create yet more length if required.
Such occurrences are rare but with vehicles becoming busier with comms
equipment positioning needs to be more carefully considered.
