MOXA Uport 1250I

by | May 6, 2014 | USB to Serial Interface

Uport 1250I2-port RS-232/422/485 USB-to-serial converter with 2 KV isolation protection

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. This plug & play USB solution is perfect for mobile, instrumentation, and point-of sale applications.

Simplified, Hassle-free Serial Port Expansion

USB plug & play makes serial port expansion easy, and does not require IRQ, DMA, or I/O address resources. Users no longer need to open the chassis or power down the system to add COM ports, saving on setup time and cost.

Top Serial Performance

Moxa’s 20-plus years of experience in serial board design is now built into a new top performance CPU called MOXA ART. This chip equips the UPort™ 1250/1250I converters with USB 2.0 (Hi-Speed 480 Mbps), a 128-byte FIFO, on-chip hardware and software flow control, and burst data mode, making Moxa’s UPort™ converters the top performing USB-to-serial converters in the world.
