Some versions of the NavQPlus do not include the IX Ethernet interface . They will have part numbers that have -XE in their part numbering indicating "no ethernet"
i.e. 8MPNAVQ-4GB-XE or
part number 8MPNAVQ-8GB-XE
IX industrial ethernet defines a new rugged and small connector type for traditional 100BaseTX and 1000BaseTX interfaces. These traditionally would use RJ45 with plastic clips whereas IX industrial is primarily metal shell and clip design. The signals used are exactly the same and only the connector changes to the IX connector. Both IX-to-IX cables as well as IX-to-RJ45 cables are available off the shelf.. Plugging an IX-to-RJ45 cable into the NavQPlus will allow you to connect via ethernet to a laptop. An IX-to-IX would allow connection to the NXP MR-T1ETH8 ethernet switch board or similar industrial equipment. Note that the MR-T1ETH8 was was also made for mobile robotics with the intention of demonstrating the NavQPlus being able to connect to a multitude of T1 devices such as Automotive Radar modules and cameras. The IX Ethernet interface on NavQPlus is capable of gigabit 1000BaseTX speeds.
There are two boards from the mobile robotics team that can also convert from T1 Ethernet back to a 100BaseTX:
