MOXA UPort 1250 USB to 2-port RS-232/422/485 Serial Hub

Condition: New

The UPort® 1250/1250I USB-to-serial converters allow you to connect 2 RS-232/422/485 devices to your laptop or workstation through the USB (Universal Serial Bus) port.These plug & play USB solutions are perfect for mobile, instrumentation, and point-of sale applications.

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

Hi-Speed USB 2.0 for up to 480 Mbps USB transmission
921.6 kbps maximum baudrate for super fast data transmission
128-byte FIFO and on-chip H/W, S/W flow control
15N high retention type B connector
Drivers provided for Windows, WinCE, and Linux
LEDs for easy monitoring
15 kV ESD protection for all serial ports
Locking power cord for the UPort 1250I
