VME-CAN2 configuration

Remember that there are 4 possible card configurations named 0 to 3.

The configuration of the VME-CAN2 card is done by setting jumpers on the card. In the following ASCII diagrams each pin is represented as an o. A jumper is shown as a line connecting two pins e.g. o-o. Jumper-blocks are shown with pin 1 in the upper-left corner. The location of the jumpers can be found by the markings on the VME-CAN2 card or by the card’s hardware manual.

Jumpers that have always to be set that way

Here is the ascii diagram:

J1: o o  (standard non-
      |   privileged
    o o   data access)

     o
     o

SW1: 0 CAN Net 1 Id: 0
SW2: 0 Bitrate for CAN Net 1, factory setting
SW3: 1 CAN Net 2 Id: 1
SW4: 0 Bitrate for CAN Net 2, factory setting
