USING TACHOGRAPH

FM6320 device can read tachograph data. User can connect FM to vehicle unit tachograph
device. Supported devices are: Siemens VDO (DTCO 1381) and Stoneridge Tachograph (SE5000).

14.1 Connecting to tachograph

Connection to tachograph (Figure 63):
 Before connecting tachograph wires, it is required to measure CAN line resistance
while tachograph is switched off:
 Turn off the vehicle ignition;
 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.
