CyberResearch’s COMHP series is
a complete line of PCI-bus serial cards
designed for RS-232/422/485 & EIA-530
communications at up to 460.8 kbps.
Most COMHP boards include either
the 16550 UART (1- and 2-port boards) or
16554 (4- and 8-port models) standard,
upgradeable to 16850 or 16950. Others
come with either 16850 or 16854
UARTs. 16850 & 16854 UARTs
feature a 128-byte data
buffer, which can
increase the speed at
which you can
acquire
data. A
larger
buffer
makes it
easier to
program
high-speed Windows
®
applications. 16850
& 16854 UARTs make
Windows programming
easy, because they
emulate 16550s — a
worthwhile upgrade for medium
and high-performance applications.
16950 UARTS add isochronous commu-
nications and 9-bit protocols, plus pro-
grammable choice of transmission speed
— recommended for savvy programmers.
Multiport boards are available in 2, 4,
and 8-channel models. Four-channel boards
include a cable breaking out the board’s
DB-37 (37-pin) connector to four DB-9 (9-pin)
connectors. Eight-channel boards include
a cable breaking out the 78-pin connector
to eight standard DB-9 connectors. You can
request cables that break out to DB-25 (25-
pin) connectors at no additional charge by
adding the suffix –D25 to the part num-
ber (see the footnotes below).
COMHP boards include
a WinNT setup
utility, drivers
for Win 95/98/
NT/2000/XP,
DOS, QNX and
Linux, as well
as detailed and
informative
user help files.
The drivers
maximize
your PC
system’s
internal
resources
through shar-
ing of interrupts
under Windows 95/98/
NT/2000/XP, so multiple I/O ports share
the same IRQ level. Each board comes
with a detailed user’s manual.
Our multimode boards can toggle
between RS-232, 422, 485, and EIA-530 (see
chart below for a list of support modes).
Please visit www.cyberresearch.com or
call for more information. Our applications
engineers will be happy to help you in
selecting the right board for your system.

RS-232 is probably the most widely used
communication standard. It is typically limited
to a data transfer rates up to 20kbps at dis-
tances less than 50 feet. An RS-232 device
can have either a DTE (Data Terminal Equipment)
or DCE (Data Circuit Terminating Equipment)
interface circuit. These boards are DTE devices.
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.
*Factory default setting.
Board requires +3.3V @ 200mA, +5V @ 400mA, +12V @ 32 mA, & –12V @ 30mA.
Cabling: COMHP 7401 / 7801 have cables w/ 4 or 8 DB-9 connectors; for cables w/ DB-25 connectors at no extra cost, add -D25 to the part no. (e.g., #COMHP 7801-D25).
Cables with DB-25 connectors are available for COMHP 7402, 7404, and 7804, at additional cost. See pages 178 and 185 for 37-pin terminal panels.
