High-Performance, Extendable Black Box VHF Radio That Supports Your Communication and Safety for Your Boat

Installation Example

Clean Installation for Limited Helm Space

Installation example

The IC-M510BB consists of a multi-piece, CommandMic™ and black box configuration. All operations including DSC, can be made from the CommandMic™, HM-195, and the RF unit can be installed in an out-of-sight place, up to 60 ft (18.3 m)* away from the CommandMic™.

* Two OPC-1541 optional cables are required for 60 ft installation.

Install Up to Three Stations on Board, VHF Radio Available at Your Favorite Positions

Up to three CommandMic™ stations are available with the  IC-M510BB providing access to the VHF radio and Intercom functions. When using the Intercom function, you can select either one-to-all or one-to-one communication.

NMEA 2000® and NMEA 0183®-HS Provides Data Integration on Your Boat

NMEA 2000® connector

NMEA 2000® network provides plug-and-play data communication to inter-connect with other marine equipment such as an MFD (Multi-Function Display). The radio can send GNSS (GPS) position, AIS, DSC call, and radio channel to other equipment.

Integrated AIS Receiver Monitors the Movement of Other Ships

The integrated AIS receiver helps you to find ships heading toward your boat and gives you an alert for collision avoidance. You can make an individual DSC call to a selected ship from the AIS screens.

DSC Remote Control Interface for PC Console Software (EN 300 338-8 Compatible)

The IC-M510BB has a dedicated DSC Remote Control (EN 300 338-8 Compatible) terminal, allowing connection to a PC console software or external device. You will be able to centralize emergency communications control.

Two Minutes Voice Recording Function for Playback Last Call

The last call voice recording function automatically saves up to two minutes of an incoming call. You will not miss incoming messages.

Active Noise Cancelling - No Need to Shout into Your Microphone

The Active Noise Cancelling digitally removes background noise from both transmit and receive audio and provides clear communication in a noisy maritime environment.

Built-in Class D DSC, “Distress” Button Can be a Lifesaver in an Emergency Situation

With just a press of the “DISTRESS” button, the built-in DSC (Digital Selective Calling) system can digitally transmit distress information to the Coast Guard and/or other vessels. The DSC watch function continuously monitors the DSC channel (Ch. 70) for added safety and security.

Loud 1-Way RX Hailer for Radio Watch on the Deck or Tower

Optional SP-37

A built-in 15 W* amplifier increases the audio output to an external hailer speaker. The 1-way RX hailer function enables you to keep watch of the radio traffic on the deck or tower through the hailer speaker. You can also sound foghorn patterns from the hailer speaker.

* 13 W for the Europe Version.
