Model: MW-LITER3
TWELITE R3 is an adapter that connects TWELITE to a PC via USB. It is used for detailed application configuration and programming.

1 - TWELITE R3 Datasheet

Latest Edition
TWELITE R3 is an adapter that connects TWELITE models with a 7P interface, such as TWELITE CUE and TWELITE ARIA, to a PC via USB. It enables communication with TWELITE CUE/ARIA over USB and is also used for application configuration and programming.

Features

  • Compatible with TWELITE series such as TWELITE CUE and TWELITE ARIA
  • Enables configuration and rewriting of applications for TWELITE series on a PC
  • Can supply power to TWELITE from a mobile battery or USB power source
  • Compliant with RoHS, conforming to new environmental standards

Components

  • USB Connector Type: USB Type-C
    The manufacturer of the USB connector used is subject to change without notice.
  • USB-UART Conversion IC: FTDI FT230XQ
