Devices on the bus are normally interconnected by cables with dual
male/female connectors at each end to allow easy cable stacking. The
24 conductor cable pinouts are shown in Figure A-2. Signal levels are
0 and 3.3 Vdc with 0 being the logic true level. Cable connectors are
modified Amphenol 24 pin Blue ribbon style connectors (57-30240)
with metric jack screws.
