National Instruments - select this if your system has a National Instruments brand PCI-CAN/2 interface
card.
Softing - select this if you are using a compatible Softing brand CAN BUS interface card

Dewetron DAQ - select this option if your system has any 16-bit ORION card with the CAN option
Dewetron DSA - select this option if your system has any 22- or 24-bit ORION card with the CAN option
⇒ Note - if your DEWESoft license does not include the CAN option, you will not be able to proceed with hardware
setup after selecting a real CAN interface card. Please contact Dewetron for a license upgrade.
After doing the hardware setup, please visit the CH SETUP screens and click on the CAN icon, which will
appear there in the toolbar.
At rst you will have no channels or messages being shown. This is normal.
Notice that there are buttons for CAN0 and CAN1. That is because there are two CAN interfaces in nearly
every system. Your system could even have more -- in which case you will have additional buttons for CAN2,
CAN3, etc. The maximum is 8 interfaces in one Dewetron system.
It is essential to select the correct SPEED of the bus, in kBaud. Dewetron CAN hardware supports speeds
up to 1 Mb (1,000,000 bits per second). 500 kb is the default.
⇒ Selecting a wrong SPEED of the CAN bus can actually interfere with certain systems, so please take care to select
the correct one.
Setting up your channels
It is important to know that the CAN data stream does not contain any information about the channels that
are being conveyed within the 64-bit messages. Therefore you need to know the conguration. Most car
companies are very secretive about the CAN message layout, and do not release this information. Dewetron
