9. Reference: Connector Pinouts and Cable Signal Mappings
This section contains complete pinouts for the connectors on the IVNT-03, as well as those on the network interface cables used to attach to it. For your convenience, tables are also provided that show the mappings of signals between pin numbers on the connectors of each network cable.
9.1. neoVI FIRE 2 Connector Pinouts
We’ll start with the pinouts for the connectors on the FIRE 2 itself.
HD-26 Connector Pinout

µDB-9 Connector Pinout
The pinout for the µDB-9 connector on the FIRE 2 can be seen in Figure 21. Note that the I/O channel numbering (which skips 3 and 4) is designed to ensure backward compatibility with the original neoVI FIRE.

9.2. FIRE 2 Ethernet Cable Adapter Connector Pinouts and Signal Mapping
The primary cable for connecting the Fire 2 to vehicle networks has four connectors: HD-26, DB-25, DB-9 and RJ-45. The HD-26 connector mates to the HD-26 on the FIRE 2 uses the same pinout shown in Figure 21; the others are described below, followed by a signal mapping table.
DB-25 Connector Pinout
This table lists the pins of the DB-25 connector on the FIRE 2 Ethernet Cable Adapter.

Cable Signal Mapping
For easy reference, Table 9 shows the mapping of signals for the FIRE 2 Ethernet Cable Adapter, by pin order on the HD-26 that connects to the IVNT-03.
9.3. neoVI-OBD-1 Cable Connector Pinouts and Signal Mapping
This OBD cable contains a DB-25 connector that mates to the DB-25 on the FIRE 2 Ethernet Cable Adapter and an OBD-II / J1962 connector for your vehicle or bench.
DB-25 Connector Pinout
Table 10 shows the pinout of the DB-25 connector on the neoVI-OBD-1.
Figure 25: neoVI-OBD-1 Cable DB-25 Connector Pinout
OBD-II / J1962 Connector Pinout
Table 11 contains the pinout for the OBD-II / J1962 connector on this cable.
Figure 26: neoVI-OBD-1 Cable OBD-II / J1962 Connector Pinout. The table shows standard signals for the OBD-II connector; this includes J1850, which is not supported by the IVNT-03.
Cable Signal Mapping
Table 12 contains the mapping of signals for the neoVI-OBD-1 cable. The signal names for both connectors are shown and the table is based on the OBD-II connector’s pin order.

9.4. neoVI-OBD-MULTI (Regular and Right Angle) Cable Connector Pinouts and Signal Mapping
These two cables have the same pinouts and signal mappings, as they differ only in the physical construction of the OBD-II connector.

OBD-II / J1962 Connector Pinout
The pinout for the OBD-II / J1962 connector on this cable can be found in Table 14.
Figure 29: neoVI-OBD-MULTI Cable OBD-II / J1962 Connector Pinout. The table shows standard signals for the OBD-II connector; this includes J1850, which is not supported by the IVNT-03.
Cable Signal Mapping
Table 15 contains the mapping of signals for the neoVI-OBD-MULTI regular and right angle cables. The signal names for both connectors are shown and the table is based on the OBD-II connector’s pin order.

9.5. neoVI FIRE/RED J1939 Cable Connector Pinouts and Signal Mapping
This cable converts the neoVI DB-25 connector to a 9-pin Deutsch connector for use in commercial vehicles.
DB-25 Connector Pinout
Table 16 contains the pinout of the DB-25 connector for this cable.

9.6. FIRE 2 OBD Cable with DoIP Support Connector Pinouts and Signal Mapping
This special OBD cable replaces the FIRE 2 Ethernet Cable Adapter and contains HD-26, DB- 25, DB-9 and OBD-II connectors. The HD-26 connector mates to the HD-26 on the FIRE 2 and uses the same pinout shown in Table 4; the other connectors are described below, along with a signal mapping table.
DB-25 Connector Pinout
Table 19 lists the pins of the DB-25 connector on this cable.
