The neoNub Blue OBD-II (J1962) adapter converts the DB-25M connector on neoVI devices to a standard OBD-II connector.
The neoNub Blue provides many advantages over other
- Eliminates a Cable: Mounting the neoNub on a neoVI device means you don't need the cable portion of the OBD II cable, saving space and weight.
- Standard Connector: The DB-25 is an "off-the-shelf" standard connector that can be purchased at local electronics stores for convenience.
- Fully-Populated: All 16 OBD-II signals are linked to the DB-25 connector; most OBD-II solutions only populate part of the cable. For example, many won't support both Single Wire CAN and Keyword 2000.
- Reduces OBD-II Connector Wear: The OBD-II connector is designed for relatively few connection cycles, which can lead to wear-out on test vehicles or benches. The neoNub can be left on the vehicle, allowing you to connect and disconnect the more robust DB-25 connector easily.
The standard pinout of the neoNub Blue meets OBD-II requirements, including those that add CAN and GMLAN.
WARNING: Make sure to check your OBD-II connector for any
non-standard layouts that may interfere with the signaling on the neoVI
