Detailed description

MasterBus RJ45-terminator frá MASTERVOLT, vörunúmer 77040000, er óvirkt viðamót sem nauðsynlegt er fyrir heilindi og bestu mögulegar vinnsluhæfni allra MasterBus-netja. Hönnunin er fyrir MasterVOLT-kerfi fyrir orkustjórnun og samskipti á sjó og er þessi terminator ómissandi til að tryggja ótruflaða virkni og háa gagnaflutningshraða innan netsins.

Virknisvið og samþætting í MasterBus-neti

Aðalhlutverk terminatorsins er að koma í veg fyrir óæskileg endurvarp á merki á endum netsins. Án viðeigandi terminator er hætta á að rafmerki endurvarpi á endum rafleiðara, sem getur valdið truflunum, gölluðum gögnum og verulegri minnkun á vinnsluhæfni netsins. MasterBus RJ45-terminator starfar sem viðnám til að stilla viðnám, gleypir merkið á endanum á línunni og tryggir þannig hreina og stöðuga sendingu. Hann er í grundvallaratriðum sambærilegur við viðnámsterminatora í NMEA 2000- eða CAN bus-netum, en sérstaklega hannaður fyrir MasterBus-samskiptastaðal MASTERVOLT.

Samræmi og áreiðanleiki

Þetta viðamót er framleitt af Advanced Systems Group EMEA B.V. undir vörumerkinu MASTERVOLT og er í samræmi við evrópskar og breskar reglugerðir. Það uppfyllir meðal annars RoHS-reglugerðina (2011/65/EU og breytingar (EU) 2015/863) og RoHS-reglugerðina 2012 í Bretlandi (SI 2012 No 3032), sem staðfestir að ekki séu til skaðleg efni. Samræmi er lýst samkvæmt staðlinum EN 63000:2018 (NEN-EN-IEC 63000:2018 en) varðandi mat á rafrásum og rafeindatækjum. Þetta samræmi tryggir traust og örugga samþættingu í skipastöðum, sem er vott um gæði fyrir viðamót sem eru þó óáberandi en lífsnauðsynleg fyrir samskipti alls kerfisins.

« The essential component for the stability of your MasterBus network »

Although often overlooked, the MasterBus RJ45 terminator is a fundamental component for the stability and performance of any Mastervolt system based on the MasterBus protocol. Its role is to prevent signal reflection at the ends of the bus, a phenomenon that, if left unchecked, can cause sporadic communication errors, network slowdowns, or even complete system failures. In a marine environment where data reliability is critical for energy management and safety, the correct integration of these terminators is non-negotiable. Using original MASTERVOLT components, RoHS and UKCA/CE certified, ensures perfect compatibility and electrical performance compliant with the manufacturer's specifications, essential for the longevity and efficiency of the installation.

Frequently asked questions

Need help? Contact us

What is a MasterBus RJ45 terminator used for?

The MasterBus RJ45 terminator is an essential component for the proper operation of your MasterBus network. It is installed at each end of the communication bus to prevent signal reflections that can cause interference and data errors. By absorbing the signal at the end of the line, it ensures stable communication and high throughput across the entire network.

Is the MasterBus RJ45 terminator required on my network?

Yes, using a terminator at each end of the MasterBus network is strongly recommended, if not mandatory, to ensure the system operates correctly. Without termination, electrical signals can reflect off the cable ends, leading to data loss, slowdowns, and erratic operation of connected devices.

Can I use a NMEA 2000 terminator instead of the MasterBus terminator?

No, it is not recommended to use a NMEA 2000 terminator instead of the MasterBus RJ45 terminator. While both networks use similar connectors, their electrical specifications and communication protocols may differ. The MasterBus terminator is specifically designed for the impedance and characteristics of the MASTERVOLT MasterBus network, ensuring proper termination and optimal performance.

Is the MasterBus RJ45 terminator compatible with all Mastervolt equipment?

Yes, the MasterBus RJ45 terminator is designed to be compatible with all Mastervolt MasterBus network devices. It is a standard component of the system, used to terminate the communication bus. It works with all Mastervolt devices that connect via the MasterBus protocol, such as chargers, inverters, control panels, and battery monitors.

How to install the MasterBus RJ45 terminator?

Installing the MasterBus RJ45 terminator is very simple. Just plug it into a free female RJ45 port located at the end of your MasterBus network. No tools or software configuration are required. Ensure the terminator is properly seated to guarantee reliable electrical contact.

What is the difference between a MasterBus cable and a terminator?

The MasterBus cable is used to physically connect the various devices together to form the communication network. The terminator, on the other hand, is a small connector that plugs into the end of the network to absorb the signal and prevent interference. In short, the cable carries the signal, while the terminator properly terminates it.

Is the MasterBus RJ45 terminator supplied with a cable?

No, the MasterBus RJ45 terminator is a standalone component and does not include a cable. It is a small connector that plugs directly into an RJ45 port. You must use MasterBus cables (references 77040020, 77040050, etc.) to interconnect your devices.

Can I make my own MasterBus terminator?

Do not build your own MasterBus terminator. Terminating a communication network requires a resistor of precise value (usually 120 ohms for CAN networks, but this may vary) and flawless manufacturing quality to avoid signal issues. A non-compliant terminator could cause network malfunctions. Use the official MASTERVOLT terminator instead.

What happens if I forget to install a terminator on my MasterBus network?

If you forget to install a terminator at one end of your MasterBus network, you risk communication issues. Signals may reflect, causing interference, data errors, slowdowns, or even a complete loss of communication between devices. The network may become unstable, and some equipment may not be detected.

Is the MasterBus RJ45 terminator compatible with CAN bus networks?

Although MasterBus is based on a technology similar to CAN bus, it uses a proprietary MASTERVOLT protocol. The MasterBus RJ45 terminator is specifically designed for this protocol. It is not guaranteed to function correctly on a standard CAN bus network (such as NMEA 2000) and vice versa. For a MasterBus network, use only the MASTERVOLT terminator.

Is the MasterBus RJ45 terminator waterproof?

The available documentation does not specify an IP rating (water or dust resistance) for the MasterBus RJ45 terminator. Like any electronic connector, it should be installed in a dry location, protected from water splashes, preferably inside an electrical panel or a protective enclosure.

Can I use the MasterBus RJ45 terminator on an NMEA 2000 network?

No, the MasterBus RJ45 terminator is specifically designed for MASTERVOLT’s proprietary MasterBus network. The NMEA 2000 network uses different connectors and impedance (typically T-connectors and 120 ohm resistors integrated into terminators). Using a MasterBus terminator on an NMEA 2000 network is incompatible and could damage the equipment.

How do I know if my MasterBus terminator is faulty?

A faulty MasterBus terminator can manifest as intermittent communication issues on your network: devices no longer responding, data errors, or a network that works intermittently. As there is no visual diagnosis, the best way to check is to replace it with a new terminator and see if the issues disappear. You can also measure its resistance with a multimeter (it should be around 120 ohms).

Is the MasterBus RJ45 terminator supplied with a warranty?

As a MASTERVOLT product, the MasterBus RJ45 terminator is covered by the legal conformity warranty. For more details on specific warranty conditions, please refer to our site’s general sales terms or contact our customer service. The exact duration and terms may vary.

Is the MasterBus RJ45 terminator a certified product?

Yes, the MasterBus RJ45 terminator is certified. It complies with the European RoHS directive (2011/65/EU and amendment (EU) 2015/863) regarding the restriction of hazardous substances. It also holds a UKCA declaration of conformity for the British market (SI 2012 No 3032). Compliance is declared according to standard EN 63000:2018.
