USB OEM - add-on module

USB slave interface for retrofitting

By using the W&T USB interface module you can convert any serial terminal device into a USB device without having to delve into the development of hardware and complicated driver problems.



  • Equip your serial terminal devices with a modern USB slave interface
    with no development on your part:
    Simply add a tiny interface module
  • USB 2.0 Full Speed Device (12 Mbit/s)
  • Common solution for Windows, Linux and Mac:
    • Addressable as virtual COM interface under
      Windows 98 / Me / 2000 / XP / Server 2003 / Vista / Server 2008 (x86 and x64)
    • Adds an access possibility to the USB device using DLL function invocations
    • Supports Mac OS 8, OS 9 and OS X
    • Supports Linux without additional drivers for kernel version 2.4.0 and higher
  • Supports all serial data and handshake lines
    • RxD, TxD, RTS, CTS, DSR, DTR, DCD, RI

Background information:

The USB add-on module has everything you need for fast interface migration: Complete driver support for all common operating systems and a hardware concept which is based on the proven FTDI USB-UART family.

The USB device can be accessed either through a serial port (VCP) or from your own programs by invoking DLL functions. These go far beyond the function scope of the VCP solution and allow for virtually free configuration of the port. For additional information, please send us an e-mail.
