NAVIS Voice operator workstation


Voice operator workstation model Navis with Unicom software

The operator interacts with the terminal through a touch screen monitor, in addition to the standard mouse and keyboard

The user will also have available, as standard equipment with the terminal, a pair of earphones (with microphone and PTT button),

and integrated speakers

Every operator can interact with the system through specific interfaces, with which it is possible to configure the parameters of the radio

resources available.

The operator can also verify the status of other operators in the network, can make full duplex calls to other terminals or PSTN lines,

and can communicate through text messages.

The main functions of the User Terminal are: 

● Telephone communications;

● Access to the remote radio devices in half duplex mode with transmission enabled by the PTT on the NavisTerminal

● Visualization of the parameters of the radio resource in use (radio type, frequency, channel, status and so on);

● Control of the radio resource in use with the possibility to change channel, frequency and other working parameters;

● Ability to control and manage up to four simultaneous communications;

● Simultaneous reception on several different channels;

● Possibility to send the audio to several conversations at the same time;

● BITE function;

● Possibility to assign and configure audio communication to any output device such as earphones, speakers, and so on.

VHF Coastal Transceiver with secure mode

VHF coastal transceiver model NTR-2224 with secure mode

NTR-2224 is an all-in-one marine VHF transceiver supporting narrowband FM/PM mode (with channel spacing of 25 kHz or 12,5 kHz) designed to comply for safety and general communications.
NTR-2224 has a form factor that enables installation into a standard four-unit rack-mountable module named NSU-1124. Each NSU-1124 can contain up to 4 radios.

Main features of VHF Coastal Transceiver
  • Secure mode
  • Full IP connectivity:
    Wide range of implemented protocols: independent TCP/IP connections (remote client or server), SNMP, SNTP, TFTP for automatic firmware upgrade, HTTP for Web access and remote management.
  • VoIP:
    Customizable VoIP session for audio streaming (including multicast)  and full-IP remote control.
  • Remote control via RS232 and RS422:
    Fully concurrent with IP and VoIP control.
  • BITE:
    Self-monitoring of internal parameters and auto-recovering when fault condition disappears (non-volatile alarm log memory). Alarm signalling on TCP/IP connections, RS232 and RS422, SNMP traps.
  • Data-link function:
    9600 bit/s on 25 kHz channels.
  • Full-duplex capable
  • 600-Ohm dedicated analog input, output and recorder lines
  • On-site operation:
    Keyboard, display and microphone plug for quick on-site tests.
  • Modularity:
    High modularity for easy maintenance.
  • Resilience:
    External structure in aluminium with high immunity to shock and vibrations.
