9.6. Deutsch 9-pin (J1939 Type 1) Cable [J1939-FIRE-CABLE]
Figure 88: neoVI RED 2 Deutsch 9-pin (J1939 Type 1) cable
This cable converts the female DB-25 on neoVI hardware devices or other cables to a Deutsch 9-pin (J1939) cable for use with commercial vehicles. It uses the standard J1939 pinout, including dual CAN channels.
NOTE: This cable does not support the neoVI BLUE with dual CAN, but may be used with it for single CAN J1939.

9.7. OBD Multi (Right Angle Connector) [NEOVI-OBD-MULTI-RIGHT]
Figure 89: neoVI RED 2 OBD Multi (Right Angle Connector)
This cable converts the DB-25M connector on many Intrepid hardware devices to a right-angled OBD-II connector, for applications where this is required. It differs from the NEOVI-OBD-1 in that its pinout matches the needs of most newer vehicles using multiple DW CAN channels.
Note that this cable is the same as the NEOVI-OBD-MULTI except for the shape of the OBD-II connector.
