Cable Signal Mapping
Table 20 contains the mapping of signals for the neoVI FIRE/RED J1939 cable. The signal
names for both connectors are shown and the table is based on the Deutsch 9-pin connector’s
pin order. Note that signals on the Deutsch 9-pin that are not used have been omitted from this
table.

6.7 neoVI FIRE 2 OBD Cable with DoIP Support Connector Pinouts and
Signal Mapping
This special OBD cable replaces the
neoVI 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
RAD-Galaxy Ethernet Cable Adapter
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 21 lists the pins of the DB-25 connector on this cable when used with the RAD-Galaxy.
Note that the LIN channel pin does not need to be used for DoIP Ethernet Activate on this
cable, though they are electrically connected.
