Suitable Cable Types

DCell/DSC CAN Bus Cable

The Cable requirements are dependent on the bit rate of the CAN bus and the required distances. Special care is
required for bit rates of over 500Kbps not only in the choice of cable used but how the bus wiring is organised ie the
requirement for very small stub lengths for high bit rates.
For low bit rates the requirements can be specified as follows
A suitable type is BICC Brand-Rex BE56723 (also equivalent to Belden type 8723).
In the UK, this is available from Farnell, part number 118-2117.
For bit rates above 500Kbps the following is recommended
Belden B3084A
Belden B8132

Indication Of Maximum Bus Length

The following indication is for the communications lines only. It does not include the power lines, which may limit
the length further due to voltage drops and initial power supply level.
