Cabling Requirements for the NI 9866

This section deals with cabling specifications, termination
resistors, cable lengths, and the number of LIN nodes that can
exist in a system.

Cable Specifications

LIN cables should meet the physical medium requirement of a
bus RC time constant of 5 µs. For detailed formulas for
calculating this value, refer to the Line Characteristics section of
the LIN specification. Belden cable (3084A) and other
unterminated CAN/Serial quality cables meet these requirements
and should be suitable for most applications.

Cable Lengths

The maximum allowable cable length is 40 m, per the LIN
specification.

Number of LIN Devices

The maximum number of devices on a LIN bus is 16, per the LIN
specification.
