2) The converter is connected to Units and/or to the onboard CAN-bus using CAN
connector (see 1.3 ) by means of Molex 6 pin connector and wires from the delivery set , in
accordance with the designation of the connectors contacts, the colour and marking of the
wires, according to table 3.

* Transit power supply for CANCrocodile / FMSCrocodile contactless readers for safe
connection of MasterCAN CAN2RS to CAN bus wires.
IMPORTANT: The presence of 120 Ohms terminal resistors between the wires
CAN LOW and CAN HIGH wires at the ends of CAN 2.0B (SAE J1939) communication
line is the obligatory condition for correct data transfer. In case of converter
connection to the
Telematics terminal that has no inbuilt terminal resistor, connect
S6 CW plugs (see delivery set and figure 7).
