The UPort? 1450 converters are compatible with new and legacy serial devices, and are 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? 1450/1450I 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 perform far better than the competition.
