Victron RS485 to USB Interface 1.8m Cable

DESCRIPTION

Victron RS485 to USB Interface Cable: Reliable Data Communication for Energy Monitoring

Purpose-Built for Victron Energy Meters and GX Devices

The Victron RS485 to USB Interface 1.8m Cable provides a direct, wired connection between Victron Energy Meters and GX monitoring devices. This cable enables stable, real-time data transfer for precise energy monitoring in off-grid, marine, and industrial power systems. Unlike generic USB-to-serial adapters, this interface is engineered specifically for the Victron ecosystem, ensuring seamless compatibility and reducing the risk of communication dropouts or data corruption.

With a 1.8-metre length, the cable offers practical flexibility for routing within enclosures or between components. The wire-ended design allows direct termination into screw terminals, eliminating the need for additional connectors and simplifying installation.

Engineered for Industrial Environments

Built with a 6-core UL2464 24 AWG (approx. 0.205 mm²) cable, this interface withstands harsh conditions. The operating temperature range of -40 °C to +85 °C ensures reliable performance in extreme heat or cold, making it suitable for engine rooms, outdoor cabinets, and remote installations. FCC, CE, and RoHS compliance confirms adherence to international safety and environmental standards.

The integrated USB 2.0 full-speed interface supports data rates up to 3 Mbaud, providing responsive, low-latency communication. This is critical for systems where accurate, timely data from energy meters informs battery management and load decisions.

Key Features

  • Direct connection for Victron Energy Meters to GX devices via RS485 protocol
  • 1.8-metre cable length for flexible installation without excess slack
  • Wire-ended termination with colour-coded conductors for straightforward wiring
  • 6-core UL2464 24 AWG (approx. 0.205 mm²) construction for durability and signal integrity
  • USB 2.0 full-speed interface with data rates up to 3 Mbaud
  • Wide operating temperature range: -40 °C to +85 °C
  • FCC, CE, and RoHS compliant for global use
  • Supports extension up to 100 metres between GX device and energy meter

Simplified Integration with Victron Systems

This cable is designed for plug-and-play operation with Victron GX devices such as the Cerbo GX and Color Control GX. The USB-A connector houses the RS485 interface electronics, while the stripped wire ends connect directly to the energy meter terminals. The colour coding follows Victron’s standard: orange (Data +), yellow (Data -), and black (GND). Three additional wires (red, green, brown) are included for future use or specific meter configurations, providing versatility without clutter.

For larger installations, the RS485 bus can be extended up to 100 metres using appropriate twisted-pair cabling, allowing energy meters to be placed far from the GX device without signal loss.

Why Choose a Victron Interface Over Generic Adapters?

Generic USB-to-RS485 converters often lack the precise impedance matching and signal conditioning required by Victron’s communication protocol. This can lead to intermittent data errors, unrecognised devices, or complete communication failure. The Victron interface is tested and validated for use with their energy meters, reducing troubleshooting time and ensuring data integrity from day one.

By using the correct interface, you protect your investment in Victron monitoring equipment and avoid the hidden costs of system downtime or inaccurate energy readings.

Applications

  • Connecting Victron Energy Meters (VM-3P75CT, VM-3P75CT-2, etc.) to Cerbo GX or Color Control GX
  • Marine and RV power monitoring systems requiring reliable data links
  • Off-grid solar installations with remote energy metering
  • Industrial battery monitoring and energy management

WARRANTY

Victron Energy Limited Warranty Policy

Direct Customers

Victron Energy provides the following warranty to any direct customer (OEM, distributor or dealer) in relation to any products that Victron Energy has directly sold to the direct customer. This warranty is not an end-user warranty between Victron Energy and an end-user, and end-users shall not have any rights or remedies under this limited warranty towards Victron Energy directly. The direct customer shall, in turn, ensure that the end-user is provided with a warranty identical to this warranty, subject to applicable local mandatory law.

End-Users

Victron Energy may also provide a warranty directly to end-users, in which case the below warranty conditions equally apply to such warranty. In that case, end-users shall claim their warranty at their place of purchase or through the original direct customer of Victron, which can be found through the support section on Victron’s website https://www.victronenergy.com/support. Hence, the direct customer shall on behalf of Victron Energy deal with any warranty claims made under any warranty that Victron Energy may provide directly to end-users. This support section on Victron’s website https://www.victronenergy.com/support will provide further guidance on the procedure for end-users to make a claim under this limited warranty.

If the end-user is a consumer – a natural person who is acting for purposes which are outside that person's trade, business, craft or profession – the following applies. The rights and remedies granted to the consumer under this limited warranty are without prejudice to the consumer’s statutory rights. Furthermore, the consumer is entitled by law to remedies from the seller free of charge in the event of a lack of conformity of the goods (such as repair, replacement, price reduction or rescission), which remedies are not affected by this limited warranty.

Warranty

Victron Energy warrants its products to be free from defects in workmanship and materials for a period of 5 years from the date of purchase by the original end-user, with a maximum of 66 months from the Victron Energy invoice date. Exceptions on this are: lead-acid batteries: 2 years from date of purchase by the original end-user, with a maximum of 30 months from the Victron Energy invoice date, Lithium batteries: 3 years from date of purchase by the original end-user, with a maximum of 42 months from the Victron Energy invoice date. In addition to this, proof of correct battery usage is required when making a battery warranty claim.

For a 10% surcharge on the current net price for products that came with a 5-year warranty, an additional 5 years of warranty can be purchased by Victron’s direct customers, bringing the total warranty to 10 years. Warranty extensions need to be applied for ultimately one year before the expiration of the original term. Victron may ask proof that the product was still functional at the time of purchase of the extended warranty.

During the warranty period, Victron Energy will, at its discretion, repair, replace or (partly) credit the defective product free of charge. The warranty does not include performing or reimbursing de‐installation, transportation, and re‐installation.

This warranty will be considered void if the unit has suffered any physical damage or alteration, either internally or externally, and does not cover damages arising from improper use like:

  • Reversed battery polarity.
  • Inadequate connection.
  • Mechanical shock or deformation.
  • Contact with liquid or oxidation by condensation.
  • Use in an inappropriate environment (dust, corrosive vapour, humidity, high temperature, biological infestation, etc.).
  • Breakage or damage due to lightning.
  • Connection terminals and screws destroyed or other damages, like overheating, due to insufficient tightening.
  • For any electronic breakage except due to lightning (reverse polarity, over‐voltage due to external cause), the state of the internal control diode and/or the input/output X and Y capacitors determine the warranty.

This warranty will not apply where the product has been misused, neglected, improperly installed, or repaired by anyone other than Victron Energy or one of its authorized Repair Centres. In order to qualify for the warranty, the product must not be disassembled or modified.

This warranty and our warranty obligations thereunder (repair, replacement or credit) are the direct customer’s and, if applicable, the end-user’s sole rights and remedies and our sole obligations with respect to any defective and/or non-conforming product or breach of warranty and is subject to and without prejudice to the limitations of liability in this warranty.

Victron Energy shall not be liable for damages, whether direct, incidental, special, or consequential, even caused by negligence or fault.

As a product requires service, it must be brought back to the place of purchase. In case no contact can be made with the merchant, or if he is either unable or not allowed to provide service, direct contact should be made with Victron Energy through the support section on Victron’s website.

In case Victron Energy replaces a product, it will own the replaced product. Victron Energy owns all parts removed from repaired products. Victron Energy uses new or reconditioned parts made by various manufacturers when performing warranty repairs or building replacement products.

If Victron Energy repairs or replaces a part of a product, its warranty term is not extended: the warranty will apply for the remaining term of the original warranty term. For example, if Victron Energy replaces a product with a 5-year warranty after 3 years, the warranty of this product will apply for another 2 years, with a minimum of 6 months.

All remedies and the measure for damages are limited to the above. Victron Energy shall in no event be liable for consequential, incidental, contingent or special damages, even if having been advised of the probability of such damages.

The foregoing limited warranty provided by Victron Energy is in lieu of any other warranties, express or implied arising by law, course of dealing, course of performance, usage of trade or otherwise, of any kind whatsoever including, without limitation, warranties of merchantability or fitness for a particular purpose, with respect to any product. The above is without prejudice to the arrangement for consumers detailed above.
