3.1 Installation of the CAN bus connection
Before the CAN bus to PC adapter is put into operation, the 9-pole Sub-Min-D-Plug and the COMBICON plug
must be connected using a CAN bus cable. The COMBICON plug can then be connected to the CAN bus
interface of an E•LDS component (e.g. AL 300, CI 3000). Special details for the connection to the CAN bus
(specification of conductor type, permissible conductor length, necessary terminating resistor and correct
routing) are described in detail in the chapter Introduction.
The following 3 steps are required:
1.
Connect the CAN bus cable to the Sub-Min-D plug (see table 3.1-1 and picture 3.1-1)..

If the adapter is at the end of the CAN bus line, a
terminating resistor
must
be inserted between pin 2 and
pin 7: R = 100 Ohm / 0.25 W (see picture 3.1-1)
