NOTE:

If harness repair/analysis is performed, MOST bus Twist Pair unshielded wire should be 0.35 mm² (22 AWG) wire with at least one twist per each 1 45/64 inch (45 mm) and must not be untwisted for more than 3 15/16 of an inch (10 cm).

The following conditions need to be met to ensure a valid continuity:

Untwisted length for all MOST 50 circuits at each wire harness connector should be no longer 50 mm max (25 mm preferred).
When wire repairs are made, a minimum 25 twists/meter for all MOST 50 circuits.
MOST 50 has specific receive and transmit I/O.

The transmit of one module is connected to receive of the next module in ring topology.
