Cable MasterBus 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 network control peripherals.

This ultra-short 20-centimetre length is ideal for daisy-chaining devices installed side by side in an electrical panel. It minimizes clutter and avoids 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 T-connector.

No, in addition to 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. The connection is made by a simple secure snap-in.

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

The interconnecting 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 close 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 be required.

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

It is strongly discouraged to cut or modify this pre-assembled cable. Any modification could degrade data transmission quality and cause network failures. If you need 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 inverters require their own dedicated power wiring; the MasterBus cable is only used for their communication.

No, this product (reference 77040020) includes only the 0.2 m communication cable. MasterBus terminators are sold separately or may sometimes be supplied 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 detect 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 run 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 in the same electrical enclosure.
