Extra-long Victron system networking
Route reliable Victron communications across large RVs, marine vessels, equipment rooms, and off-grid properties with one genuine, factory-terminated 20-meter cable.
The Victron RJ45 UTP cable 20m is the exact ASS030065031 accessory for long-run VE.Bus and supported VE.Can connections. At approximately 65.6 feet, this genuine Victron Energy cable gives installers the reach to connect equipment located in separate bays, cabins, engine rooms, control panels, or utility spaces without adding intermediate couplers or improvised extensions.
Connect equipment across a large RV, boat, workshop, or off-grid property without piecing together shorter network cords.
The extended length supports routes from a lower equipment bay to an interior control cabinet, from a marine engine room to a helm station, or from a detached inverter room to a nearby monitoring location. Measure the complete routed path—including service loops and bends—before ordering.
A single 20m cable can simplify troubleshooting and cable management by reducing the need for inline couplers, field crimps, or multiple patch leads hidden behind walls and bulkheads.
Use the correct network, port, pinout, and termination for every connected device.
Use for supported connections involving Digital Multi Control, Inverter Control, the MK3-USB interface, multiple VE.Bus devices, and a GX device. This is a common long-run choice when a MultiPlus or Quattro installation is located away from the monitoring panel.
Use for supported VE.Can links to a Cerbo GX, Ekrano GX, or other compatible GX device. A VE.Can daisy-chain requires proper termination at both open ends; the cable length does not eliminate that requirement.
Do not connect an Epoch or third-party battery to a GX device based only on matching RJ45 sockets. Some managed batteries use a standard straight-through cable, while others require a specially pinned CAN-bus BMS cable or manufacturer-supplied harness. Follow the exact battery manual.
The cable uses RJ45 unshielded twisted-pair construction with a straight-through pinout. A crossover cable must not be substituted for Victron VE.Bus or VE.Can communication.
For dependable troubleshooting and support, retain the factory connectors whenever possible. Poor field crimps can create intermittent faults that are difficult to diagnose, especially when the cable is hidden inside a finished RV or vessel.

Frequently asked questions
This genuine Victron Energy cable carries communication data between supported Victron components. Common uses include VE.Bus links between compatible MultiPlus or Quattro inverter/chargers, connections to Digital Multi Control, Inverter Control, or MK3-USB interfaces, and supported VE.Can device-to-GX connections.
Twenty meters equals approximately 65.6 feet or 787.4 inches. This extra-long reach is useful when a battery bank, inverter/charger, or networked device is installed in an engine room, basement bay, utility room, or solar shed while the GX device or control panel is mounted much farther away.
No. Twenty meters is an official Victron-manufactured length for this RJ45 UTP cable family. Reliable operation still depends on using the correct ports and network type, keeping the straight-through factory connectors intact, securing the cable properly, applying the required VE.Can termination, and following the routing guidance in the connected-device manuals.
Keep communication wiring separated from AC conductors and high-current DC cables where practical, especially over a long parallel route. If the paths must cross, cross them at approximately 90 degrees, protect the cable from sharp edges, and follow applicable electrical and marine installation standards.
Only when the documentation for that exact Epoch battery and Victron system specifies a standard straight-through RJ45 UTP cable. Some managed-battery integrations require a specially pinned VE.Can-to-CAN-bus BMS cable or an Epoch-supplied communication harness. Never connect the devices solely because both ports use an RJ45 connector.
VE.Bus is commonly used by compatible Victron inverter/chargers and related control devices. VE.Can is a CAN-bus network used by compatible GX devices and supported CAN products, and it requires termination at the two open ends. VE.Direct uses a smaller proprietary connector and requires a VE.Direct cable, so this RJ45 cable is not a substitute for VE.Direct wiring.
Cutting and re-terminating the cable is not recommended. Poor RJ45 crimps are a common source of intermittent communication faults that can be difficult to diagnose. For the most supportable installation, retain the factory-terminated cable and manage any excess length with a protected service loop.
Yes. Cable length does not replace network termination. A VE.Can daisy chain needs a terminator at each open end. VE.Bus connections do not use VE.Can terminators, so first confirm which network and ports you are installing.
It is a straight-through RJ45 UTP cable. Do not substitute a crossover cable, because crossover wiring is not suitable for Victron VE.Bus or VE.Can equipment.
Confirm the exact port type, network profile, cable pinout, termination method, and device-manufacturer instructions before installation. RJ45 describes the connector shape—not universal electrical compatibility. This cable carries communication data and does not replace required battery power cabling, fuses, breakers, or system protection.
