Instant Plug & Play
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.
