NXU-2: Latest Software Upgrade

This page contains instructions for updating the firmware in the NXU-2 to version 3.0 with WAIS support. The link below contains a ZIP file containing the new firmware file and a NXU-2 firmware update program.

This update adds some new features formerly found only in the NXU-2A. These are Connectionless (WAIS) and Multicast Modes, QoS Support, and the ability to designate different VoIP ports for the Server and the Client. See the NXU-2A manual for details on these features.

Note: The Server Port must now be designated on the Client Configuration Page in order for a link to be established. Set to match the Server’s actual VoIP port (usually 1221). A “0” setting will not link.
