OVERVIEW
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.
And wouldn’t you prefer to use an external connection to
connect your serial peripherals instead of installing a PCI or
ISA card in your system? BLACK BOX

USB Hubs enable you
to do just that.
These hubs are available with two, four, or eight ports for RS232, 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.
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. These compact units connect to peripheral serial
devices in external plug-and-play fashion. And they’re hotswappable—you don‘t have to turn off your PC to install one.
Setup is easy. The hubs are shipped with drivers on a CDROM. 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.
When testing in loopback mode, a port LED flashes and
the interface screen displays echoed data (in the form of a hex
pattern and ASCII data strings) to verify the hub’s readiness
for use in your application.
