Typical Application—Connecting Instruments in a Medical Lab

In medical labs, research scientists typically collect large quantities of data from many samples using a variety of different instruments. Most research devices have parameters that can be accessed via a serial port for convenient reconfiguration. Laptops are often used as convenient and space-efficient computing solutions in medical labs, but most modern laptops no longer offer serial ports and only come equipped with USB ports. This presents a connectivity issue unless the USB ports can be expanded into serial ports.
Moxa’s solution is the UPort® 1250, which is an RS-232/422/485 USB-to-serial converter that can be used to connect 2 serial interface instruments to a computer’s USB port, and is particularly convenient for medical researchers since advanced technical expertise is not required. The UPort® 1250 has the following features:

  • 2 serial ports for easy USB-to-serial expansion
  • True USB 2.0 high-speed transmission
  • 128-byte FIFO and on-chip hardware and software flow control to ensure stable data transmission
  • Easy troubleshooting with LED indicators for each serial port
  • Compatible with both laptops and desktop PCs
