29 VDC operation:
Examples of max. cable lengths in meters for different
cable types and source impedance.
Note Remember that the total max. cable length from the mini-C to the
last unit on the CAN bus
must never exceed 200 m
! See The
CAN backbone on page 32.

a. This is not the calculated length, but the max. CAN cable length from the
mini-C to the last unit on the CAN bus. You must take into consideration the
length of the cable from the T-connector to the power supply (max. 6 m),
and the length of cables from the mini-C to the last unit on the CAN bus
(max. 200 m).
