OPC-1540 connection cable

The OPC-1540 cable is used to connect remote accessories, such as the HM-162E control microphone, to your Icom marine VHF radio. It carries power and communication signals.

This connection cable measures exactly 6 meters in length, providing good flexibility to connect the radio base unit to the helm station.

The OPC-1540 cable is an official accessory specifically designed for use with Icom marine VHF installations.

This cable is ideal and specifically designed to connect the Icom HM-162E remote control microphone to your main VHF base.

Yes, the system is modular. You can add one or two additional extension cables of model OPC-1541 (each also 6 meters long) to increase the distance of your installation.

By combining the OPC-1540 base cable with two OPC-1541 extensions, you can achieve a maximum total offset of 18 meters.

Yes, the OPC-1540 cable harness includes the necessary wires to directly connect a waterproof external speaker for sound on your deck or cockpit.

For the audio connection, the identification is straightforward:

The yellow wire corresponds to the audio hot lead.The black wire corresponds to the audio ground.

Yes, it is designed for marine environments. It connects the radio base located inside the cabin to an external helm station exposed to the elements.

Yes, the cable provides reliable and simultaneous transmission of communication signals (audio and control) as well as electrical power to the remote accessory.

A standard marine electrician's toolkit is sufficient. You will need wire strippers and waterproof connectors (or heat-shrink tubing) to securely connect the speaker to the audio wires and prevent corrosion.

The modular design of Icom’s OPC-1540 connection cable provides several key benefits for marine VHF installations, particularly in complex setups:

Increased mounting flexibility: This cable is specifically designed to offer high flexibility when installing remote accessories, such as the HM-162E control microphone. It allows you to position these components optimally on your boat, even when the main transceiver is located far away.Extension of remote distance: Unlike standard wiring, which is often limited in length, the OPC-1540 can be paired with one or two OPC-1541 extension cables (each 6 meters long). This allows for a maximum remote distance of 18 meters, enabling you to install a communication station at a significant distance from the radio base.Adaptation to complex configurations: This modular architecture is ideal for vessels requiring a remote pilot or communication station, ensuring reliable transmission of communication and power signals over longer distances.Integration and scalability of the Icom system: The cable fits within a logic of integration and scalability of Icom systems, facilitating a clean and efficient installation for communications and connection of external speakers.

No, it is strongly recommended to use the official Icom OPC-1540 cable. It has the specific connectors, the correct number of pins, and adequate shielding to ensure proper VHF operation.

You can connect a maximum of two OPC-1541 extension cables in series with your OPC-1540 cable to ensure the integrity of the audio signal and data.

No, connecting an external speaker amplifies the receive audio on deck, working in synergy with your remote control station for improved audibility.

This is a 6-metre black cable with the Icom reference OPC-1540. It is distinguished by its specific connectors for VHF and microphone, as well as the presence of two bare wires (yellow and black) dedicated to audio.

Yes, this cable transmits all control signals. It allows channel changes, volume adjustment, or use of ASN/DSC functions directly from the remote HM-162E microphone.

Yes, as a marine VHF installation accessory from the Icom brand, its sheath and connectors are designed to withstand harsh conditions and the salty air of the marine environment.

The system is optimized for 5W RMS (10W Peak) speakers. Using a much more powerful speaker is not recommended, as the VHF's internal amplifier will not deliver the necessary power to drive it properly.
