nit. NXU units connect communications equipment to a
digital network using VoIP (Voice over Internet Protocol) technology. NXU units use JPS’
proprietary technology, embodied in a family of hardware and software products that enable
voice communications devices to be interconnected via a network across the room or around the
world. VoIP is a means of digitizing voice signals and transmitting them over a digital network,
such as a LAN, WAN, or even the Internet itself.
The NXU-2B is standards-compliant and therefore supports standards-compliant web browsers,
including Microsoft Edge, Firefox, Chrome, Opera, and Safari. It’s always best to use the most
current version of any web browser.
The NXU-2B is intended for use with radio communications consoles, communications radios,
and JPS products such as the ACU-1000 Interconnect Unit. This general-purpose, stand-alone
device interfaces full duplex audio, one RS-232 port, and three status bits onto an Ethernet
network. A pair of NXU-2Bs can form a simple system that creates a transparent communications
link between the two. The NXU-2B at one end (usually the equipment end) is the
server
; the one
at the other end (usually the operator end) is the
client
. The audio, RS-232, and status bits are
transparently transferred between the server and the client.
Any NXU-2B can be set up as a server or as a client depending on system needs. The RS-232
interface allows for different baud rates between the server and the client.
The NXU-2B monitors its network connection and adjusts its parameters automatically to
provide optimum performance under varying network conditions. Front panel indicators display
the unit’s status. Configuration is done through the NXU-2B’s Ethernet port using a standard
web browser.
Designed for years of continuous operation in mission-critical applications and remote locations,
the NXU-2B has no moving parts and requires no periodic shutdown or maintenance. Startup
upon power on is under 10 seconds.
