Victron RS232 to USB Converter Cable

DESCRIPTION

Victron RS232 to USB Interface Cable for Reliable Data Communication

Seamless Connectivity Between Legacy RS232 Devices and Modern USB Systems

The Victron RS232 to USB Converter Cable provides a dependable bridge between Victron equipment featuring an RS232 port and computers or GX devices with USB inputs. Engineered for industrial and datacommunication applications, this cable ensures stable signal conversion for configuration, monitoring, and system integration tasks. Its shielded design minimises electromagnetic interference, making it suitable for environments where data integrity is critical.

Whether you are configuring a Victron inverter/charger, integrating a battery monitor into a larger energy management system, or performing firmware updates, this converter cable delivers consistent performance. The plug-and-play nature reduces setup time, while the robust construction withstands the demands of field use.

Key Features

  • Converts RS232 serial signals to USB for direct connection to modern hardware
  • Shielded cable with silver braided jacket protects against signal noise and physical wear
  • Male DB9 RS232 connector and standard USB Type-A connector for broad compatibility
  • Compact, lightweight design for easy transport and installation in tight spaces
  • Compatible with Victron products featuring an RS232 interface, including inverter/chargers and battery monitors

Built for Industrial and Mobile Environments

Unlike generic USB-to-serial adapters, this Victron cable is purpose-built for the specific voltage levels and communication protocols used in Victron energy systems. The clear-jacketed silver braided shielding reduces the risk of data corruption caused by nearby power cables or radio frequency interference—a common challenge in off-grid solar installations, marine engine rooms, and vehicle-based setups. The moulded strain relief on both connectors extends cable life by preventing breakage at stress points.

For installers and system integrators, this reliability translates to fewer troubleshooting callbacks and more consistent system performance. The cable’s length provides flexibility in equipment layout without excessive slack that could create trip hazards or snag points.

Applications

  • Configuring Victron inverter/chargers and solar charge controllers via VE.Configure software
  • Connecting a Victron battery monitor to a PC for data logging and analysis
  • Integrating legacy RS232-based Victron devices into a Victron GX system (e.g., Cerbo GX) that lacks a native RS232 port
  • Performing firmware updates on compatible Victron hardware
  • Industrial automation setups requiring reliable serial-to-USB conversion

Why Choose the Victron RS232 to USB Cable?

Using a standard, non-Victron USB-to-serial adapter can lead to communication errors, driver conflicts, or even hardware damage if voltage levels are mismatched. This Victron cable is validated for use with their product range, reducing the risk of compatibility issues. The integrated electronics handle signal level conversion accurately, ensuring that commands and data are transmitted without corruption. For professionals who depend on precise energy management, this reliability is essential.

Additionally, the cable’s shielded construction helps maintain signal integrity over longer cable runs compared to unshielded alternatives. This is particularly beneficial in installations where the computer or GX device must be located some distance from the Victron equipment.

Get Connected with Confidence

Equip your toolkit with the Victron RS232 to USB Converter Cable and streamline your Victron system configuration and monitoring. Whether you are a marine electrician, off-grid solar installer, or DIY enthusiast, this cable provides the reliable link you need. Add it to your order today and ensure seamless communication between your Victron devices and USB-enabled hardware.

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.

As a general policy, Victron Energy does not recommend the use of any of its products in life support applications where failure or malfunction of Victron Energy's product can be reasonably expected to cause the failure of the life support device or to significantly affect its safety or effectiveness. Victron Energy does not recommend the use of any of its products in direct patient care. Victron Energy will not knowingly sell its products for use in such applications unless it receives in writing assurances satisfactory to Victron Energy that the risks of injury or damage have been minimized, the customer assumes all such risks, and the liability of Victron Energy is adequately protected under the circumstances.

Warranty on repairs for products outside their warranty period

The warranty period on products that are outside their warranty period and have been repaired by Victron Energy or one of the Victron Energy Repair centres is six (6) months from delivery. The same applies to spare parts and circuit boards that have been supplied or repaired by Victron Energy.

Transport
