FEATURES
• Provide an easily configurable interface
that’s simple to connect.
• Some models meet a variety of
interface standards.
• Advanced buffered UARTs for faster
data transmission.
• Low-profile models fit in the PCI slots
of newer, slimmer PCs.

models.
• Drivers for all Windows operating
systems are included.
Connect up to 31 RS-485 devices to each port
on the Quad-Port RS-232/422/485 PCI Card.
OVERVIEW
When you need to add extra PCI ports to your personal
computer, select a PCI card from Black Box. All our
cards feature speedy buffered Universal Asynchronous
Receiver/Transmitters (UARTs); these are integrated circuits
that convert bytes from the computer bus into serial bits
for transmission.
The cards are designed to maximize DOS, Linux
®
, OS/2®,
QNX, Windows
®
95/98/Me/XP, Windows 2000, Windows NT®,
and UNIX
®
communications. Windows drivers, utilities, INF
files, and help files are included to simplify installation.
Configure the cards’ ports as RS-232 for standard serial
COM-port requirements, and you can use a card for modems,
printers, plotters, and similar devices.
The RS-232 adapters support distances between devices of
up to 50 feet (15.2 m).
Use RS-422 mode for long-distance device connections that
require noise immunity and high data integrity (like industrial
automation and control applications).
Or, select RS-485 and capture data from multiple
peripherals in an RS-485 multidrop network. This communications link between multiple locations uses multiple local
exchange carriers. Up to 31 RS-485 devices can be connected
to each port to automate your data collection.
The RS-422/485 cards support distances between devices
of up to 4000 feet (1219.2 m).
In both RS-232 and RS-422 modes, the PCI cards work
seamlessly with your standard operating system’s serial driver.
In RS-485 mode, the cards’ special autoenable feature allows
the RS-485 ports to be viewed by the operating system as
a COM port. This enables you to use a standard COM driver
(instead of a custom software driver) for your high-speed
RS-485 connections. It also makes the cards compatible
with DOS and Windows 95/98 or Windows NT.
These PCI cards are easy to set up and use. Install
an adapter in any of the PCI expansion slots on your PC.
Configuring a card is just a matter of setting one or a few
jumper straps. I/O addresses and IRQs are automatically
assigned by your PC motherboard’s BIOS. And, because
these cards slide into any standard PCI slots, you don’t have
to install a data-conversion box. They’re ideal for field use!
Integration problems are a thing of the past with the
adapters. They support all PCI interrupts, providing a wider
range of IRQs that will be assigned by the BIOS when
installing.
All card versions come with serial utility test software
to aid in troubleshooting hardware conflicts. The software’s
easy-to-use diagnostic program even verifies your installation.
