USBM232-xxx RS232 Mouse Adapter   by Versalent   Home

Converts a wired USB mouse to an RS232 mouse for your non-USB system!
Uses any standard wired USB mouse converting it to an RS232 Serial Mouse for general use with any UART system. USBM232 is the first device to provide a simple USB HID host which can communicate with a standard USB mouse and convert the mouse movement (USB) reports to standard ASCII RS232 characters for use with any host via a serial UART. Can be ordered in DCE or DTE* pin configurations (both with DB9 female).

USBM232 Datasheet by Versalent
FEATURES
  • Converts a USB mouse to an RS232-output mouse
  • Your system does not need USB .. it receives RS232 characters
  • Uses a 2-button mouse for x-y movement, buttons clicks and scroll wheel
  • Outputs ASCII characters or MS Serial Mouse standard or extended output
  • RS-232 Connection To Host W/Selectable Baud/Parity. Baud rates from 600 to 115k
  • Operates on 5VDC, or 6-12VDC,or w/optional wall adapter
APPLICATIONS
  • Systems without USB support, or no HID drivers
  • Embedded systems needing mouse input via UART
 DESCRIPTION

       USBM232 is a 2.6" X 1.7" X 0.8" module which provides translation of the wired USB mouse signals to serial RS232 characters. This allows even small microcontroller systems to incorporate USB mice without any of the development complexity of USB and HID drivers. The RS232 (ASCII or binary) messages for each mouse movement or click are short so as to minimize transfer latency for fast mouse movement.    Manual available here

Typically works with all wired mice which do NOT require special drivers to operate on a PC. Although some mice include a driver CD for special features, many work with the default Microsoft OS USB drivers and these will work with the USBM232. Validated with:

  • HP 672652-001 (Model MOFYUO)
  • Dell OKD944
  • Logitech M90
  • 3D Optical Mouse
Software Utilities available for download

USBM232 Tester Application .. installs on your PC to set mode, sensitivity, and view mouse data.

USBM232-xxx is available with various power source and RS-232 options to provide the flexibility to mate to a variety of systems without additional adapters.
*All units whether DTE or DCE provide DB9 female connector. Small M/M adapters available for conversion.
