Victron MK2.2b VE.Bus to RS232 Interface | ASS030120210

The Victron MK2.2b is a wired interface that converts VE.Bus communication to RS232 serial protocol, letting a PC connect directly to VE.Bus-equipped inverters and inverter/chargers. It's the tool installers reach for when configuring or updating firmware on Victron's MultiPlus and Quattro ranges through VEConfigure and VEFlash.

Key features

• Protocol conversion, VE.Bus to RS232 for direct PC connectivity.
• Compatibility, works with Victron VE.Bus inverters and inverter/chargers, including MultiPlus and Quattro.
• Software support, enables configuration via VEConfigure and firmware updates via VEFlash.
• Weight, 40g, easy to keep in a tool kit.
• Identifiers, SKU ASS030120210, GTIN 8719076019404.

Product overview

RS232 remains the standard interface for VEConfigure and VEFlash, and the MK2.2b handles the VE.Bus side of that connection. Installers use it to set system parameters, adjust charge curves, configure parallel or three-phase multi-unit systems, and push firmware updates in the field.

Laptops and modern PCs without a native RS232 port will need a separate USB-to-RS232 adapter alongside this interface. The MK2.2b only performs the VE.Bus-to-RS232 conversion; it does not provide USB connectivity itself, and it is not a substitute for the VE.Bus Smart Dongle or other wireless monitoring accessories.

Applications

• Configuring Victron MultiPlus and Quattro inverter/chargers with VEConfigure.
• Uploading firmware to VE.Bus devices with VEFlash.
• Setting up parallel and three-phase multi-unit systems needing direct serial configuration.
• Field diagnostics and parameter adjustments by qualified installers.

What's in the box

• 1 x Victron MK2.2b VE.Bus to RS232 interface

Installation notes

This is a configuration and programming tool rather than a permanent installation component, intended for use by qualified installers familiar with VE.Bus systems. Confirm the correct Victron software version is installed on the PC before use, and add a USB-to-RS232 adapter if the host computer lacks a native RS232 port.
