9. Reference: Connector Pinouts and Cable Signal Mappings
This section contains complete pinouts for the connectors on the neoVI ION, 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.
Note that the USB cable is industry standard and not covered here.
9.1. neoVI ION Connector Pinouts
We’ll start with the pinouts for the connectors on the neoVI ION itself.
HD-26 Connector Pinout
A list of pin assignments for the HD-26 connector can be found in Table 4, with pin numbering for the connector illustrated in Figure 86.

9.2. ION Ethernet Cable Adapter Connector Pinouts and Signal Mapping
The primary cable for connecting the ION 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 ION and uses the same pinout shown in Table 4; the others are described below, followed by a signal mapping table.
