Reduce Total Cost of Ownership
These days, peripherals are more likely to be connected by
Ethernet or USB. The problem is how to integrate these
different interfaces. The current solution is to connect all
devices using the open standard Ethernet and USB. The
total cost of ownership is reduced, not only on short term
hardware investment, but also on long term management
and integration cost. Upgrade your existing RS-232 or RS-
422/485 software with USB connectivity by using the reliable
Windows 98/ME/2000/XP/2003 driver.
RS-232/422/485 Support
UPort 1100/1400/1600 products are mobile, expandable,
and reliable USB-to-serial hubs. UPort 1100/1400/1600
hubs support full RS-232 modem data and control signals
(TxD, RxD, DTR, DSR, RTS, CTS, DCD) and male DB9
connectors can be used to connect serial devices to the hub.
RTS/CTS hardware flow control is also supported. UPort
1100/1400/1600 come with mini female DB9 to terminal
block accessories, which makes it easy to wire RS-422 and
RS-485 applications. 4-wire RS-422/485 and 2-wire RS-485
are also supported, providing a serial data rate of up to 921.6
Kbps, and a 128-byte FIFO.
USB Bus Power Supported
UPort 1400/1600 Series hubs support both bus power and
external power via an adaptor. Bus power is adapted for
laptop or workstation connections that support 500 mA
output for USB devices. External power is adapted for those
USB hubs that can only output 100 mA of current.
