<big>Before connecting tachograph wires, it is required to measure CAN line resistance
while tachograph is switched off:<br /></big>
1. Turn off the vehicle ignition;<br />
2. Measure resistance between the C5 (CAN2 H) and C7 (CAN2 L) contacts;<br />
3. If the multimeter shows ~120 Ohms, skip the next step;<br />
4. If the multimeter shows kilo Ohms resistance then it is needed to connect tachograph C8 (CAN-RES) and C7 (CAN2 L) contacts with wire and then perform further actions;<br />
5. Re-measure the resistance of the line – it has to be ~120 Ohms.<br />
6. Connect CAN2 L and CAN2 H wires to tachograph (C5 (CAN2 H) and C7 (CAN2 L))<br />
• All of the same level CAN-L and CAN-H wires must be interlaced with each other.<br />

• CAN wires need to be installed as far as possible from GSM antenna.<br />
