
Measure resistance between the C5 (CAN2 H) and C7 (CAN2 L) contacts;

If the multimeter shows ~120 Ohms, skip the next step;

If the multimeter shows kiloOhms resistance then it is needed to connect
tachograph C8 (CAN-RES) and C7 (CAN2 L) contacts with wire and then perform
further actions;

Re-measure the resistance of the line – it has to be ~120 Ohms.

Connect CAN2 L and CAN2 H wires to tachograph (C5 (CAN2 H) and C7 (CAN2
L))

All of the same level CAN-L and CAN-H wires must be interlaced with each other.

CAN wires need to be installed as far as possible from GSM antenna.
Figure 106 Adding contact on tachograph connector

Tachograph D8 and adapter K-Line connectors connected directly.

Tachograph mounted on vehicles does not have D8 contact. In order to add it, you
have to undo the hooks and add the contacts (Figure 106). Contact code in Farnell
system: 927368-1.

Direct GND connection is required only if vehicle and tachograph grounds are not
merged. (It can be checked using multimeter. Connection between different
grounds should be 0 volts)
NOTE! Connecting to Stoneridge tachograph, for K-Line data, this configuration must take place:
1. Insert Company card in tachograph.
2. Configure tachograph in this way:
Menu->Settings->Parameters->D8 data format->SRE
Each described Vehicle Data element is packed to standard AVL packet and sent to
server. Parameter values are sent depending on configuration element ID that is described in „K
LINE ID“column (IO parameter ID).
