PC Cards with permanently attached cables and similar technical specifications are available (for more details, please visit our website).
Protected against surge voltages from –6.8V to +12V. Isolated 1500VDC or 1000VAC. Ground isolated ±50 V, DC to 60Hz.
Isochronous communication, custom baud rates, and 9-bit protocol.
Just the Ports You Need
Many applications need no more than
one or two serial communications ports, so
we have put our one-port serial cards on
page 155, our two-port cards here, and our
cards with more ports on page 157.
Failsafe Protection
To protect the integrity of your data,
the CYB-series RS-422/485 PCI and ISA
cards on this page offer failsafe open- and
short-circuit detection and protection.
Open circuits occur naturally in multi-
driver, multireceiver systems. They may
also happen unintentionally when system
wires are cut. Without failsafe open-circuit
detection, false start bits could corrupt
otherwise good data.
Short circuit conditions may damage
units on the line, corrupt data, or prevent
communication. Our on-board failsafe
protection keeps the line impedance from
going to zero, protecting the inputs of
receivers and the outputs of transmitters.
2 More Ports via PC Card or CompactFlash!
Providing two RS-232 or RS-422/485
ports, Type II PC cards offer full PCMCIA
plug-and-play, with autoconfiguring,
selectable interrupts, and full addressing.
They feature large 128-byte transmit and
receive FIFO buffers to prevent loss of data
and to simplify programming.
CYB 2422C supports (a) one talker and
many listeners; (b) many talkers and
listeners, full duplex; & (c) many talkers and
listeners, half duplex. In RS-422 mode, data
flow is software-controlled. RS-485 mode
features hardware controlled autogating.
The RS-422 card offers full modem control
of TX, RX, RTS, CTS, and GND signals.
Our new COML 2232F CompactFlash
card adds two RS-232 ports to any PC that
supports CompactFlash I/O devices. The
serial data and control lines are buffered
with isolated RS-232 drivers that allow the
RS-232 interfaces to be offset from the host
computer’s by up to ±50V. That’s ideal for
industrial environments, where long cables
can induce significant offset voltages.
2-port RS-232
PC Card
Speeds to 18 Mbps with Autogating in Half-Duplex Mode!
Add two RS-232 ports to your computer
without ever opening the case! Just install
the included drivers, slip the CompactFlash
™
card into its slot, connect the cables to
RS-232 devices, and you’re ready to roll!
With autogating and speeds to 18 megabaud,
our CYB 218MP card handles high-speed
RS-422/485 requirements with ease.
The only thing it doesn’t do is handle
data rates below 115 kbaud!

RS-232 is probably the most widely used
communication standard. The standard calls
for data rates up to 20kbps at distances less
than 50 feet, but speeds can be much higher.
An RS-232 device can have either a DTE (Data
Terminal Equipment) or DCE (Data Circuit
Terminating Equipment) interface circuit.
RS-422 is the best choice for applications
where data must travel over longer distances
(up to 4,000 feet), and where noise immunity
and high data integrity are more important.
The E
I
A-530 (RS-530) standard defines a
25-pin pinout for RS-422, as well as modem
control signals.
RS-485 is backward-compatible with RS-422,
but is optimized for multidrop networks.
Each RS-485 port can support up to 31
devices. RS-485 ports in Auto-Enable mode
appear to the host system as standard RS-232
ports, so additional drivers are unnecessary.

PCI-Bus Boards — use in either 3.3V or 5V PCI slots (CYB 218MP is 5V only); several cards include both standard (12cm) and low-profile (8cm) backplates
