IC-M510BB 21 Black Box VHF with Black Command Mic 3 Command Mic PortsIcom's IC-M510BB is perfect for boats that need AIS to receive functionality without taking up precious helm space. The supplied black CommandMic provides all the safety and communication functions for commercial and leisure boaters. Clean Installation for Limited Helm SpaceThe IC-M510BB consists of a CommandMic and a black box RF unit. Use the CommandMic for all operations, including DSC. Install the RF unit out of sight, placing it up to 60 ft (18.3 m)* away from the CommandMic.*Two OPC-1541 cables are required for the 60 ft installationCommandMic StationsAdd up to two additional CommandMic microphones for boats requiring two or three comms stations. Extend communication points around the boat, including the cockpit, flybridge, and tower. Access the intercom functions for one-to-all or one-to-one communications on the boat. AIS ReceiveThe IC-M510BB includes an integrated AIS receiver, perfect for remote station information via the CommandMic, or integrated into the NMEA 2000 bus to display radar and chart plotter information on an MFD (Multi-Function Display).DSC Functionality and Remote ControlIn addition to the conveniently located DSC button on the back of every CommandMic, the IC-M510BB introduces a dedicated DSC Remote Control (EN 300 338-8 compatible) terminal, allowing a connection to an external device to centralize emergency communications control. NMEA200 and NMEA 0183-HSThe NMEA 2000 network provides plug-and-play data communication to interconnect other marine equipment, such as an MFD (Multi-Function Display). The radio can send AIS, GNSS (GPS) position, DSC call, and radio channels to other equipment. Class D DSC FunctionalityOn the back of every CommandMic is a conveniently located DSC button. Once triggered, the IC-M510BB transmits a DSC alert signal to nearby vessels with the MMSI* and GPS location of your vessel. *MMSI number must be obtained and programmed for each vessel/radio. Loud One-Way RX HailerThe built-in 15W amplifier increases the audio output of an external hailer speaker. The one-way RX hailer function enables you to broadcast radio traffic through the hailer speaker, allowing you to listen to it on the deck or tower. You can also hear foghorn patterns from the hailer speaker. Active Noise CancellingThe Active Noise Cancellation function digitally removes background noise from transmitted and received audio to provide clear communication in noisy maritime environments.
