Control 8 or More Serial Devices from One USB Port!
Our USBS 1000 Serial Communications Converters make it easy for newer
computers with USB ports to communicate with older serial-port devices. All of
the classic serial protocols are covered: RS-232, RS-422, RS-485, and even
RS-530. Because USB data speeds are so high, by using our USBH series hubs to
attach more than one USBS unit per USB port, one downstream USB port can support
up to 16 serial ports.
USBS 1000 converters allow you to establish serial communications without
ever opening up you computer case. They also eliminate the need for such system
resources as I/O ports and IRQs to support serial communications. The series of
USB converters require a computer system that supports v1.1 USB, both in
hardware and operating system, and they come with drivers for Windows®:
98/2000/XP; Windows NT4 drivers free upon request.
The series automatically configure themselves. After you install the included
software, your computer automatically recognizes all models and configures them.
You can add or delete any number of USBS converters without ever reconfiguring
your system or fussing with jumpers and DIP switches!
Our USBS 1000 models are powered from the USB cable, so you need no
additional power supplies. However, required current can be as high as 1 amphere
on 16-port models. All USBS models should normally be connected to a
self-powered hub that is capable of supplying 500mA of current per port. Note
that the 16-port USBS 1216 requires two upstream USB ports.
Some of our USBS 1000 series converters offer surge protection for additional
safety in tough industrial environments. We recommend these surge-protected
models for all applications where speeds less than 461 kpbs and buffers no
larger than 16 bytes are appropriate.
