Although the analog two-way radio still occupies a large proportion in the field of professional wireless communication, the development of digitalization is an unquestionable trend. The NEXEDGE NX-840 digital mobile radio, which provides greater effective coverage and low noise, high-quality voice from clarity, and inherent privacy features, was born. Just as the market is eagerly awaiting Kenwood products, intuitive operation, superb performance and all-weather reliability can be standardized as expected. Not only that, the NX-840 has dual operating features: it offers both analog FM and NXDN digital modes, allowing users to smoothly transition from existing analog systems to the digital age.
NXDN Digital Standard
NX-710 is compliant with the NXDN digital technology standard and uses ultra-narrowband FDMA. The minimum spacing of digital channels can reach 6.25KHz. The frequency band use efficiency has been greatly improved.
NX-840 has a transmit power of 25W. The NX-840 UHF frequency range spans up to 70MHz.
In the analog mode, the 16-code voice scrambling encryption function helps ensure the security of communication. The high-security NXDN encryption algorithm can be used in digital mode.
32 channels/2 zones
NX-840 can be configured with two regular working zones, each providing up to 16 channels.
Digital/analog mode switchable
NX-840 combines analog and digital representations: The analog area operates on the 12.5kHV25kHz channel. The digital zone operates on the 6.25KHz/12.5kHz NXDN digital channel. Use a pre-programmed key to easily switch between the two work areas. The 6.25 kHz digital channel can effectively increase the utilization of the frequency band and provide a larger coverage than the horizontal channel.
NXDN digital regular mode
NEXEDGE digital regular mode provides 64 RAN codes (wireless access codes) for group calls and selective access to the repeater, just like QT/DQT in analog mode, ensuring fast connection and efficient communication.
By installing a GPS receiver module for the NX-840, the vehicle's accurate position data (from GPS satellites) can be sent to the central base station for fleet management to achieve automatic positioning of the vehicle.
External DB15 interface
DB15 interface socket is used to connect peripheral devices. Such as achieving ignition sensing. External switch and whistle alarm and other functions. The KCI-60 cable (optional) is compatible with the Molcx interface.
