8. Reference: Connector Pinouts and Cable Signal Mappings

This section contains complete pinouts for the connectors on the neoVI FIRE 2, 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.

8.1. neoVI FIRE 2 Connector Pinouts

We’ll start with the pinouts for the connectors on the neoVI FIRE 2 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.
