Vehicle Network and Power Connections

Two connectors on the FIRE 2 are used to attach it to vehicle networks. The HD-26 connector
on the left side of the device provides primary power input to the neoVI FIRE 2 and also carries
most of the network channels. This is also where your OBD cable is attached, either directly or
indirectly. The µDB-9 connector on the other side of the device carries LIN and miscellaneous
I/O channels, which you may or may not need depending on your application.
The connection steps are listed in a specific order chosen to make the process intuitive, and
to prioritize the power connection so you can verify quickly that the FIRE 2 is operational.
However, the steps can be performed in any order you find convenient.
HD-26 and OBD Cable Connections to FIRE 2
The connections made here will depend on which OBD cable, if any, you are using with the
FIRE 2.
If you are using no OBD cable, or any OBD cable other than the FIRE 2 OBD Cable with DoIP
Support:
1. Attach FIRE 2 Ethernet Cable Adapter to HD-26 Connector: Attach the HD-26 female
connector on the network interface cable to the HD-26 male connector on the neoVI
FIRE 2. Tighten the thumbscrews so the cable remains securely attached (Figure 52).
