MasterBus kabel 0,2 m

This cable connects MasterBus-compatible devices within your power installation. It serves two main functions:

High-speed data transfer between devices.
Power supply for small control peripherals on the network.

This ultra-short 20 cm length is ideal for daisy-chaining devices installed side by side in an electrical panel. It minimizes clutter and prevents unnecessary wiring loops.

No, this cable is specifically designed for Mastervolt's proprietary MasterBus communication protocol. Unlike the NMEA 2000 network, the MasterBus architecture does not require T-connectors.

No, the MasterBus system is based on a decentralized architecture. Each compatible device comes standard with two communication ports, allowing this cable to be connected directly from one device to another without a complex splitter.

No, in addition to providing high-speed data communication between your devices, the MasterBus cable also supplies power to low-power peripheral equipment such as displays or interfaces.

Installation is very simple: just insert each end of the cable into one of the two MasterBus communication ports available on your Mastervolt equipment. Connection is made via a simple secure snap-in mechanism.

The 0.2 m MasterBus cable is extremely light. It weighs only 20 grams, adding no weight constraint to your onboard electrical installation.

The interconnect cable does not replace a terminator. In any MasterBus network architecture, it is mandatory to install a MasterBus terminator (reference 77040000) at each end of your device chain to terminate the network.

This cable is compatible with all Mastervolt equipment featuring native MasterBus communication ports. If one of your devices does not have this port, a specific MasterBus interface will then be required.

Yes, this communication cable is specifically manufactured to withstand demanding marine environments. It ensures reliable signal transmission without interference for power management onboard your boat.

Yes. The MasterBus 0.2 m cable is CE and UKCA certified. It also complies with the RoHS directive (EN 63000:2018), which restricts the use of hazardous substances in electrical equipment.

Cutting or modifying this pre-assembled cable is strongly discouraged. Any alteration could degrade data transmission quality and cause network failures. If you require a custom length, Mastervolt offers a DIY kit.

No, the MasterBus cable only powers small control or monitoring peripherals. High-power devices such as chargers and converters require their own dedicated power wiring; the MasterBus cable is only used for their communication.

No, this product (reference 77040020) only includes the 0.2 m communication cable. MasterBus terminators are sold separately or are sometimes supplied as standard with certain major devices from the brand.

No, the MasterBus cable is fully bidirectional. You can connect either end to a MasterBus port on any device; the system will automatically recognize the connection and data flow.

Yes, the MasterBus cable is dedicated to the communication network (data transfer and low-voltage power supply for interfaces). It integrates perfectly with Mastervolt systems, whether your overall system is 12V, 24V or 48V.

No, the MasterBus network must always be installed in a line (daisy-chain) and must never form a loop or star topology. This 0.2 m cable is designed specifically to continue the line cleanly between two adjacent devices.

The official manufacturer reference from Mastervolt for this MasterBus communication cable with a length of 0.2 meters is 77040020.

Yes, its flexibility allows it to be routed through protective conduits. However, its very short length of 20 cm makes it primarily suitable for direct and exposed connections between two devices located side by side within the same electrical enclosure.
