ISA Cards
Control 1, 2, 4, or 8 devices
from a single PC.
FEATURES
OVERVIEW
• Add up to eight serial ports to your
ISA bus.
• Cards available for RS-232, RS-422/485,
RS-530, V.35, Current Loop, and MIL-188
interfaces.
• Work with DOS, Windows®, or OS/2®.
• Cards with UARTs reach speeds up to
115.2 or even 460.8 kbps.
• Cards with Zilog™ chips achieve speeds
beyond 1 Mbps!
• Optically isolated cards protect devices
from spikes and surges.
If your PC is connected to multiple peripherals—such as
modems, data-entry terminals, and printers—you can use just
one interface card to add up to eight extra ports (depending
on which model you’re using). Best of all, you don’t need to
use all your PC’s slots.
We have ISA cards that work with many popular interface
and operating system standards. For details about the
supported interfaces, see the 1-, 2-, 4-, and 8-port ISA card
descriptions on the next two pages.
Suported operating systems include DOS, Windows
3.x/95/98/Me/XP, Windows 2000, Windows NT®, and OS/2.
ISA cards operate at different speeds, depending on the
type of card interface. Some ISA cards work without an additional line driver or converter. But other ISA cards (where
noted) must use the appropriate line drivers and receivers to
achieve the specified speeds. The noted ISA cards must also be
able to optimize the other factors that affect performance
(such as CPU, number of ports, cable length and quality, and
electrical interface).
A diagnostic software program (SSD) on the included
CD-ROM tells you if your card is configured correctly.
1-Port ISA Cards
The MIL-188 ISA card (IC179C) helps you link MIL devices to
your PC—up to 4000 feet (1219.2 m) away.
The Parallel and Serial RS-232/422/485 ISA card (IC602C)
supports both parallel and serial RS-232 and RS-422/485. On
the parallel side, the card handles data bidirectionally, so you
can transmit data in two directions and double your
throughput rate to more than 400 kbps. The card links RS-232
devices up to 50 feet (15.2 m) away and RS-422/485 devices up
to 4000 feet (1219.2 m) away.
The RS-422/485 ISA cards (IC050C, IC171C) support 9 IRQs.
2-Port ISA Cards
With the 2-port cards, you can add factory-automation
equipment, such as bar-code readers, scales, drill presses, time
clocks, and other devices to your PC.
The 2-port cards are available with an RS-232 interface
(IC110C) for sustained speeds up to 115.2 kbps. Or, select the
RS-232 High-Speed cards (IC130C, IC177C). They support
sustained data-transfer speeds of up to 460.8 kbps.
The IC130C and IC177C adapters can be configured as
COM1 through COM4 to provide an RS-232 interface for a
modem, mouse, or plotter, as well as a higher-speed interface
for ISDN applications or V.34 modems.
If you need a more flexible interface, select an RS-232/422/
485 card (IC113C). It operates via 2- or 4-wire connections.

The RS-422 mode runs point-to-point and supports up
to 10 receivers, and the RS-485 mode has the electrical
characteristics to support up to 32 drivers and 32 receivers
on one line.
For faster applications, choose an RS-422/485 card. They
feature 4 IRQs (IC600C), 11 IRQs and Autoenable (IC051C,
IC176C), or optical isolation (IC057C).
These cards automatically handle low-level RS-485 driver
maintenance via hardware, so integrating an RS-485 network
is simple—with little or no programming changes within
Windows and other protected-mode operating systems.
Because the cards incorporate unique hardware circuitry that
enables the RS-485 interface to appear to be RS-232, no additional software drivers are required. Installation is as easy as
picking an address and interrupt level. This means that initial
development can be targeted for RS-232, debugged, tested,
and then implemented as RS-485.
The optically isolated card (IC057C) eliminates the
effects of spikes, surges, and ground differences to protect
communications devices connected to the PC. Isolation
is important in installations in which equipment being
connected to the PC is either far from the PC or is on a
different power transformer circuit. The isolated RS-422/485
ISA card provides up to 500 VDC of isolation.
High-speed sync/async adapters (IC121C-R3–IC122C-R3,
IC120C-R4) feature two communication channels that use
the Zilog 85230 Enhanced Serial Communications Controller
(ESCC). Depending on the model you choose, you can link
your PC to TIA RS-232, TIA RS-530, or ITU-TSS V.35 devices.
DMA on the adapters supports data rates in excess of
1 Mbps (one million bits per second). Selectable port address
is also available on the adapters.
The RS-232 adapter (IC122C-R3) supports RS-232
connections with full modem-clocking options, providing
an industry-standard interface to synchronous data links,
modems, and other devices.
The IC120C-R4 adapter supports RS-530, which is RS-422/
485 on a 25-pin connector. RS-422 allows for extended
distance communication—5000 feet (1524 m) at 9600 bps—
with virtually error-free differential drive characteristics.
RS-485 is backward compatible with RS-422 but optimized
for multidrop applications: Multiple ports can be selectively
polled. RS-530 calls for RS-422 signals on a DB25 connector.
The RS-530 standard is broken into two interfaces (DTE and
DCE), much like RS-232. In addition to the asynchronous
modem-control signals on a standard PC serial port, RS-530
specifies synchronous clock signals, modem test signals, and
loopback signals.

OVERVIEW (CONTINUED)
The IC121C-R3 incorporates the V.35 connector specification, relying on balanced twisted-pair cabling from the
board to the twisted-pair device. V.35 is used for high-speed
applications up to the 1-Mbps range and beyond.
4-Port ISA Cards
4-port RS-232 and RS-422/485 cards are available. Cards
with Interrupt Status Port (ISP), like the IC102C-R2, provide
greater throughput when servicing multiple ports (IRQ
sharing) on a single interrupt line.
The RS-422/485 card with 9 IRQs and autoenable
(IC058C-R2) enables the RS-485 transmitter during character
transmission.
The IC102C-R2 reaches maximum speeds of up to
115.2 kbps sustained or 460.8 kbps burst. For higher-speed
applications (up to 460.8 kbps sustained), order the IC058C-R2.
8-Port ISA Cards
These cards work with RS-232 interfaces with ISP. (ISP
enables IRQ sharing for higher throughput.) The IC112C-R3
supports sustained speeds of up to 115.2 kbps or burst speeds
of up to 460.8 kbps. The IC182C is designed for sustained
speeds of up to 460.8 kbps.

According to a survey by Data Communications
magazine, 90% of network managers surveyed say
that getting the technical support they need is extremely
important when choosing a vendor. But even though
network managers pay anywhere from 10 to 20% of their
overall purchase price for a basic service and support
contract, the technical support and service they receive
falls far short of their expectations—and certainly isn’t
worth what they paid.
At Black Box, we guarantee the best value and the
best support. You can even consult our Technical Support
Experts before you buy if you need help selecting just
the right component for your application.

Technically Speaking
With more people using the Internet, new demands have
been placed on computer serial ports. Many PC serial ports
aren’t equipped to handle the level of buffering required for
newer data rates. But advanced UARTs—such as the 16550,
16650, 16750, and 16850—go a long way toward satisfying
the requirements.
Each card has either a UART or an ESCC chip. Universal
Asynchronous Receiver/Transmitters (UARTs) are asynchronous
integrated circuits that convert bytes from the computer bus
into serial bits for transmission. Zilog chips (Enhanced Synchronous Communications Controller, or ESCC) are synchronous
integrated circuits.
I/O addresses and IRQs
All the UARTs in the ISA cards are buffered, so the CPU is
not constantly interrupted to process data.
The adapter is automatically assigned I/O addresses and
IRQs by the motherboard. Only the IRQ address can be
modified by the user.
16550 UART
Used in the IC602C, IC050C, IC110C, IC113C, IC600C, IC051C,
and IC057C, the 16550 features a 16-byte input and output
First-In, First-Out (FIFO) buffer that holds the characters for
the transmitter and receiver. The FIFO allows you to obtain
higher data rates while reducing the frequency of processor
interrupts. The IC602C supports speeds up to 400 kbps. All
other models with 16550 UARTs support sustained data rates
up to 115.2 kbps or bursts of data up to 460.8 kbps.
16554 and 16C554 UARTs
If you order the IC112C-R3, you’ll receive a card with two
16554 UARTs that contain four 16550 UARTs, each with a
16-byte FIFO buffer. (The total buffer for the eight ports is
128 bytes.) The IC102C-R2 has a 16C554 UART, which contains
two 16550 UARTs, each with a 16-byte buffer. (The total card
buffer for the four ports is 64 bytes.)

724-746-5500

16650 UART
A 32-byte FIFO buffer is the IC130C’s UART’s main feature.
It can handle sustained data rates up to 460.8 kbps. However,
you must use the appropriate line drivers and receivers and
be able to optimize the other factors that affect performance
(such as CPU, number of ports, cable length and quality, and
electrical interface).
16750 UART
The IC058C-R2 has a 16750 UART and a 64-byte FIFO
buffer. It also features sustained baud rates of 460.8 kbps,
but delivers better performance because of its larger buffer.
16850 UART
The most popular UART, 16850, is used in IC179C, IC171C,
IC177C, and IC176C. The 16850 UART has a 128-byte FIFO
buffer for each port. This UART features sustained speeds of
up to 460.8 kbps.
The 16850 UART has FIFO UARTs that enhance communications. They help you avoid the many I/O problems seen
in a multitasking environment—like data overruns or
underruns—that occur when the UART buffering isn’t large
enough to handle the incoming data. These, of course, can
interrupt performance and affect your communications.
The 16850 chip also supports an isochronous scheme,
which is asynchronous framing with an added clock signal.
This scheme allows for much higher data rates and digital-line
use (ISDN, T1) where a clock is supplied for data multiplexing.
And you can get high-speed communications with a simple
communications interface that responds to standard
communication calls.
16854 UART
The IC182C has 16854 UARTs. A 16854 UART contains four
16850 UARTs, each with a 128-byte FIFO buffer.
Zilog 85230 ESCC
The IC121C-R3, IC120C-R4, and IC121C-R3 cards use ESCCs.
This chip operates at speeds of 100 kbps to 1.2288 Mbps.
