Service socket for VCADS Pro

General

In principle, the machine electronics are based on all communi‐

cation between control units in the system taking place via two

data buses. The machine's control units are connected to the

buses to enable communication with each other.

Communication between the different control units as well as

reporting from control units to service sockets takes place on data

buses CAN1/J1939 and J1587/1708.

The buses follow SAE standards and consist of two pair-twisted

cables. The purpose of the twisted cabling is to protect the bus

from electrical interference.

If an error or malfunction should occur in any system, a signal is

sent out on the information bus which makes it possible to read

off the information either in the information display or with VCADS

Pro. In VCADS Pro, MID-designations (Message Identification

Description) are used for the control units.

The figure above shows the principle for how the control units and

service sockets are connected to the buses.
