FeatUReS
USB connections have replaced serial connections as the preferred
method of linking peripheral devices to computers. Why? Because USB
offers increased bandwidth, lower costs than conventional I/O ports,
and the ability to connect devices externally.

your serial peripherals instead of installing a PCI or ISA card in your

USB Hubs
enable you to do just that.
These hubs are available with two, four, or eight ports for RS-232,
RS-422/RS-485, or RS-232/RS-422/RS-485 communications.
No matter which model you choose, the
USB Hubs
enable non-
USB serial peripherals to be connected to your PC’s USB bus while
preserving serial speeds (standard PC data rates of up to 921.6 kbps).
These high-speed capabilities are the result of the hubs’ two high-
speed FIFO buffers—a 128-byte FIFO buffer for data transmission
and a 384-byte FIFO buffer for data reception.

and a 384-byte FIFO buffer for data reception.
The hubs spare you from opening your computer case, and they
don’t require resources such as input/output (I/O) ports or IRQs. In
addition, your system doesn’t need to be USB, both in terms of
hardware and operating system.

Just think of the possible applications. Instead of plugging factory
automation devices into serial ports on a PC, you can attach them to
a hub and, in turn, connect the hub to your PC’s USB bus. Data rates
continue to transfer at serial connection speeds through the externally
attached serial devices.

The
USB Hubs
are ideal for connecting factory automation devices,
such as data loggers and industrial machinery, or any device that
depends on links that aren‘t affected by excessive noise or spikes
in voltage.

And, with these hubs, you not only get industrial-quality serial
connections, but automatic RS-485 data enable/disable along with a
DB9 connector that’s compatible with PCI and ISA RS-422 products.

You don‘t need much time to connect one of the hubs, either.
OVERVIEW
These compact units connect to peripheral serial devices in external
plug-and-play fashion. And they’re hot-swappable — you don‘t have
to turn off your PC to install one.

Setup is easy. The hubs are shipped with drivers on a CD-ROM.
Screen captures, including a ”new hardware found“ wizard, are used
to locate the appropriate drivers and, once they’re found, a pop-up
window indicates correct installation of the new ports and that the
hub’s hardware is ready for use.

Each port on a USB Hub can be individually configured to the
RS- interface of your choice. To do this, simply adjust DIP switches
and DIP shunts.

LEDs indicate whether USB is enabled and if there’s activity on any
hub ports. Upon hub installation, you can begin the setup utility and
use the included loopback plug to check communications between
TD and RD.
