Victron RJ45 UTP Cable 0.9m - ASS030064921
Genuine Victron communication cable
A genuine 0.9-meter Victron RJ45 UTP cable for clean, reliable VE.Bus and VE.Can communication links.
The Victron RJ45 UTP Cable 0.9m is the official straight-through data cable for supported Victron Energy communication connections. At approximately 3 feet long, it provides practical routing between nearby devices such as MultiPlus or Quattro inverter/chargers, GX devices, control panels, MK3-USB interfaces, and compatible VE.Can equipment—without leaving excessive cable loops on an RV, marine, or off-grid electrical board.
Reliable data transfer starts with the correct cable and the correct port.
Advanced power systems depend on uninterrupted communication between inverter/chargers, GX devices, control panels, and compatible networked equipment. This genuine Victron Energy RJ45 cable provides the standard straight-through UTP connection specified for supported VE.Bus and VE.Can links, helping avoid the uncertainty of an unknown pinout, crossover cable, or poorly terminated field-made lead.
Always match the cable to the device manual and port label. RJ45 is only the connector shape; VE.Bus, VE.Can, BMS-Can, Ethernet, and special battery communication ports are not automatically interchangeable.
Use this cable for Victron connections that explicitly call for a standard RJ45 UTP lead. Common examples include VE.Bus links between a MultiPlus, Quattro, compatible inverter, or GX device; connections to Digital Multi Control, Inverter Control, or MK3-USB interfaces; and supported VE.Can device-to-GX connections.
The 0.9-meter length equals approximately 2.95 feet. It gives installers practical slack for routing between nearby devices mounted on the same solar backboard, inverter bay, electrical panel, or protected equipment compartment without creating a large coil of excess data cable.
Known part number. Known straight-through wiring. Fewer troubleshooting variables.
Victron systems use a straight-through RJ45 UTP cable—not a crossover cable. A correctly manufactured third-party straight-through cable may work in supported applications, but the genuine ASS030064921 gives you a known Victron part, factory-terminated connectors, and the exact 0.9-meter length. That removes one major variable when diagnosing VE.Bus or VE.Can communication faults in an RV, boat, mobile power system, or off-grid installation.
The cable uses eight conductors arranged as unshielded twisted pairs. Twisting the conductors helps reduce susceptibility to electromagnetic interference and crosstalk—important when data wiring shares an equipment area with chargers, inverters, DC cabling, and other electrical hardware.
Pre-terminated RJ45 connectors click into compatible ports for fast installation with no cutting, crimping, or pinout work. In mobile systems, route and support the cable so the connectors are not placed under tension, pinched, or exposed to abrasion.

Do not assume this standard straight-through cable is the correct battery communication lead simply because both devices use RJ45 sockets. Many managed lithium battery connections require a specially pinned VE.Can-to-CAN-bus BMS cable or a manufacturer-supplied communication harness. For an Epoch-to-Victron integration, follow the exact Epoch battery manual and Victron port instructions for that model. Use ASS030064921 only when the documentation specifically calls for a standard straight-through RJ45 UTP cable.
Exact part details and supported communication uses.
Match the network, port, pinout, and termination method before connecting.
Power down equipment when required by the device manuals, verify that you are using the correct VE.Bus or VE.Can port, and push each RJ45 connector fully into place until the latch engages. Keep the cable separated from sharp edges and high-heat surfaces, add strain relief where needed, and never force an RJ45 connector into an unrelated Ethernet, BMS-Can, or specially pinned battery port.
Frequently asked questions
This genuine Victron Energy cable carries communication data between supported Victron components. Common uses include connecting VE.Bus inverter/chargers such as MultiPlus or Quattro units to a compatible GX device, linking Digital Multi Control or Inverter Control panels, connecting an MK3-USB interface, and making supported VE.Can device-to-GX connections.
A 0.9-meter cable is approximately 35.4 inches or 2.95 feet—just under 3 feet. It is well suited to short equipment-board runs where the connected devices are close enough to avoid a longer coil of unused cable.
A properly manufactured straight-through RJ45 UTP cable can work in Victron connections that call for a standard cable, but a crossover cable cannot. The genuine Victron ASS030064921 removes uncertainty about the part number, wiring format, connector termination, and cable length. Never select a cable based only on the fact that the plug looks like Ethernet.
Only when the specific Epoch battery documentation calls for a standard straight-through RJ45 UTP cable in that position. Many managed battery-to-GX connections require a specially pinned VE.Can-to-CAN-bus BMS cable or an Epoch-supplied communication harness. Follow the exact battery manual, port labels, DIP-switch instructions, and Victron CAN profile for your model.
It is a straight-through RJ45 UTP cable. Each pin connects to the same pin number at the opposite end. Crossover cables are not suitable for normal Victron VE.Bus or VE.Can connections.
For a standard VE.Can daisy-chain network, install the correct VE.Can terminator at each open end of the network. VE.Bus connections do not use those blue VE.Can terminators; unused VE.Bus ports should remain open. Managed battery networks may have different termination requirements, so follow the battery and GX device manuals.
