ATEN VK211 RS-232/CONTACT TO USB Keyboard Converter

Overview

The ATEN VK211 is a specialized converter designed to bridge legacy RS-232 serial data or simple contact closure signals into USB keyboard input. This unit is rack-mountable, making it suitable for integration into control room environments or server racks where direct keyboard emulation from serial devices is required. It simplifies the process of connecting devices that lack native USB or modern serial interfaces to computers or systems expecting keyboard input. The VK211 model supports firmware upgrades, ensuring potential future enhancements or bug fixes.

Compatibility

This converter is designed to emulate a standard USB keyboard. It is compatible with any host system that supports USB Human Interface Device (HID) keyboards, including Windows, macOS, and Linux operating systems. The RS-232 input allows for connection to a wide range of industrial equipment, network devices, or custom-built systems that output serial data. The contact closure input enables integration with simple switches, buttons, or trigger mechanisms that can activate keyboard emulation commands.

Installation Notes

The VK211 features a rack-mountable form factor for easy integration into standard server racks. It requires an optional power source via a USB Micro B female port. A pushbutton toggle switch is included for remote control and can be used to enter learning mode by pressing and holding for 3 seconds. The device operates within a humidity range of 0-80% RH, non-condensing. Firmware upgrades are managed via a provided zip file, indicating a need for a USB connection to a host system for maintenance.
