User´s Manual - I+ME ACTIA GmbH

The CAN Setup window above shows how to put in BTR values manually.
Custom:
Click in this box to enable the BTR input fields.
BTR 0 + 1:
Put in the Hex Values for the desired Baud Rate or to adjust the Sample point. The Baud Rate will be
calculated and shown depending on the inputted BTR values.
Note: the user has to put in the BTR values for the SJA 1000 CAN Controller used by CAT.
It is not possible to try out any BTR values and see what
transfer speed you can get! There are too many values that are not possible and can
put the CAN chip in an erratic state. Take only exact calculated values
that take care of the BTR restrictions. See also in the SJA1000 data sheet.
Here are the values that are already predefined (to be selected by Baud Rate):
BTR0 / 1 – Speed [kbps]
40 14 – 1000
80 25 – 800
c0 49 – 500
c1 49 – 250
c3 49 – 125
c3 5c – 100
c6 36 – 95.2
85 2b – 83.333
c3 7f – 80
c5 5a – 75
c7 49 – 62.5
