Genuine Victron long-run communication cable
A genuine 10-meter Victron Energy RJ45 cable for supported VE.Bus and VE.Can communication across large RV, marine, and off-grid installations.
The Victron RJ45 UTP Cable 10m is the official straight-through communication lead listed as part ASS030065011. At approximately 32.8 feet long, it provides the reach needed to connect supported inverter/chargers, GX devices, control panels, and networked equipment installed in separate rooms, bays, cabinets, or protected compartments—without joining multiple short patch cables.
Route critical system data across larger RVs, boats, cabins, and equipment rooms.
Modern inverter, charger, battery, and monitoring systems rely on dependable low-voltage communication. This genuine Victron Energy 10-meter RJ45 UTP cable provides the standard straight-through connection specified for supported VE.Bus and VE.Can links while allowing your power equipment and control hardware to be installed where each component fits best.
The RJ45 plug shape does not make every port interchangeable. Always verify the network type, port label, cable pinout, device firmware, CAN profile, and termination requirements in the applicable Victron and battery manuals before connecting equipment.
The 10-meter length equals approximately 32.81 feet. It is well suited to routes from an RV pass-through bay to an interior control cabinet, from a boat engine room to a protected helm electronics space, or from a remote inverter wall to a centrally mounted GX device.
Use this cable where the Victron equipment manual calls for a standard straight-through RJ45 UTP lead. Typical applications include VE.Bus links for MultiPlus, Quattro, compatible inverter/charger units, Digital Multi Control, Inverter Control, and MK3-USB, plus supported VE.Can device-to-GX connections.
Official 10-meter length. Straight-through wiring. Fewer troubleshooting variables.
Victron specifies straight-through RJ45 UTP cabling for supported VE.Bus and VE.Can products and explicitly warns against crossover cables. A properly manufactured third-party straight-through cable can work where a standard cable is specified, but choosing the genuine ASS030065011 preserves a known part number, factory termination, and exact length—valuable advantages when the cable will be concealed behind panels or routed through an entire vehicle or vessel.
The eight-conductor unshielded twisted-pair construction helps reduce cross-talk and electromagnetic interference compared with untwisted communication wire. Good routing, secure connectors, and correct network termination remain essential in electrically noisy RV, marine, and off-grid installations.
Factory-terminated straight-through RJ45 connectors simplify installation and eliminate the uncertainty of field-crimped ends. Push each connector fully into the correct port until the latch engages, then provide strain relief so the cable cannot tug on the equipment socket.
One continuous factory cable for equipment mounted far apart.
Matching RJ45 plugs do not guarantee matching communication wiring.
Use this cable only where the equipment documentation specifies a standard straight-through RJ45 UTP lead. A managed lithium battery may require a specially pinned CAN-bus BMS cable rather than this standard cable. Never use an RJ45 crossover cable, and never connect equipment based solely on connector appearance.
Exact part number, cable length, wiring format, and supported communication uses.
Test the full 33-foot route before closing walls, floors, panels, or equipment covers.
Power down equipment when required by the manuals, confirm the correct VE.Bus or VE.Can port, and insert each connector until its latch engages. Route the cable through protected pathways using broad bends and proper strain relief. Keep it away from sharp edges, high-heat surfaces, and strong interference sources where practical. For VE.Can, install the required terminators at the network ends and select the correct CAN profile on the GX device.
Frequently asked questions
This genuine Victron Energy cable carries communication data between supported Victron components. Common uses include VE.Bus links between MultiPlus, Quattro, and compatible inverter/charger devices; connections to Digital Multi Control, Inverter Control, or MK3-USB interfaces; and supported VE.Can device-to-GX connections.
Victron sells this exact 10-meter RJ45 UTP cable for supported communication applications. The twisted-pair construction helps reject interference, and 10 meters is an official factory length. Reliable operation still depends on using the correct ports, proper VE.Can termination where required, secure connectors, and sensible routing away from strong interference sources.
Ten meters equals approximately 32.81 feet, 393.7 inches, or about 33 feet. This length is useful when a battery bank, inverter/charger, or networked device is installed in a lower storage bay, engine room, or utility space while the GX device or control panel is mounted in a separate cabin or equipment area.
Only when the specific Epoch battery documentation calls for a standard straight-through RJ45 UTP cable in that exact connection. Some managed battery integrations require a specially pinned VE.Can-to-CAN-bus BMS cable or an Epoch-supplied communication harness. Follow the battery manual, port labels, CAN profile, and termination instructions for your exact model.
VE.Bus and VE.Can commonly use RJ45 connectors, but they are different communication networks and must be connected only as the equipment manuals specify. VE.Bus is commonly used by MultiPlus and Quattro inverter/chargers, while VE.Can is used by compatible CAN-network devices and managed battery interfaces. VE.Direct uses a smaller proprietary connector, so this RJ45 cable is not a VE.Direct cable.
An experienced installer can technically re-terminate a straight-through UTP cable, but Victron does not recommend making these communication cables yourself. A poor crimp or incorrect pin order can create intermittent, difficult-to-diagnose faults. Using the factory-terminated 10-meter cable preserves the known part, pinout, and connector quality.
A standard VE.Can daisy-chain must be terminated at both open ends with the correct VE.Can terminators. VE.Bus connections do not use those VE.Can terminators, and unused VE.Bus ports are generally left open. Managed battery networks can have model-specific termination requirements, so follow both the battery and GX device manuals.
Use a protected pathway with broad bends and strain relief, keep the cable clear of sharp edges and high-heat surfaces, and avoid long parallel runs directly against high-current DC or AC wiring where practical. Do not pull the cable by the RJ45 plug, crush it under panels, or tightly coil excess length around power conductors. Test communication before closing walls or equipment covers.
