The UPort® 1600-16 USB-to-serial converters allow you to connect 16 RS-232 or RS-232/422/485 devices to your laptop or workstation through the USB (Universal Serial Bus) port. The UPort® 1600-16 converters are compatible with new and legacy serial devices, and are perfect for instrumentation, and manufacturing applications.


Typical Application—TFT-LCD Manufacturing

Manufacturing TFT-LCD (thin film transistor liquid crystal display) panels is a complicated and highly technical process. The three major stages in TFT-LCD panel production are the array, LC cell, and module assembly processes. In addition, each finished panel must also pass a series of quality inspection tests, which include defect inspection and lighting tests. The most challenging part of the TFT-LCD manufacturing process is achieving zero fault tolerance for high quality and productivity. One of our customers needed a USB-to-serial solution to transmit data between a host and quality inspection equipment in the TFT-LCD manufacturing process. In such a demanding manufacturing environment, adopting multiple ports and Moxa’s ruggedly designed UPort® 1650-16 USB-to-serial converter proved to be the best option. The UPort® 1650-16 has the following features:

  • Standard 19-inch rackmount size and metal housing for
  • industrial-grade requirements
  • Up to 16 ports for easy USB-to-serial expansion
  • 3-in-1 serial ports for a cost-effective solution
  • True USB 2.0 Hi-Speed transmission for greater productivity
  • 128-byte FIFO and on-chip hardware and software flow control to ensure stable data transmission during inspection
  • Each serial port has its own LED indicator for easy troubleshooting
