The original standard, or SCSI-1, is based on an eight-bit bus with a
synchronous transfer rate of up to 5MB/s. For SCSI-1, FCAI provides 50-pin high density
(1.27 mm pitch) connectors in various configurations. SCSI-2, or "Wide SCSI," is
based on a 16-bit bus and SCSI-3, or "Fast SCSI," supports up to 10MB/s transfer
rate. FCAI offers SCSI-2 and –3 connectors in the same high-density configurations as
for SCSI-1, but with 68 pins.
A
SCSI bus can connect up to seven devices to a single controller on the computer bus.
Single-ended SCSI supports up to six meters of cable and differential supports up to 25
meters of cable. And when the signal reaches the end of the cable, terminate it! FCAI
offers both single-ended and differential external terminators to maintain signal
integrity.

and I/O connectors, backshells and accessories, consult the product finder under

Up on USB
It looks like the Universal Serial Bus is finally on a roll. We’re
already seeing systems with a USB port and experts predict that by the end of 1998, USB
peripherals will begin appearing on retailers shelves. The most common devices will
include game controllers, keyboards, CD-ROMs, mice and scanners.

The
USB bus enables users to connect up to 127 peripherals on a single port and supports both
isochronous and asynchronous data transfers. It offers the ability to add devices, with
automatic configuration, or remove them, while the PC is running. In addition, USB can
directly support fax machines and telephones. Using USB, a telephone can link directly to
the PC, yet retain its phone line connection as well.
In short, USB represents versatility and simplicity, which is good news
for most PC users. So if your device doesn’t include a USB port, chances are the user
will opt for another device that does. Be sure and check out FCAI's line of USB connectors
and input devices.
FCAI
offers myriad connectors in its FCN-230 series that meet SCSI 1, 2 and 3 standards. Its
offering of Small Computer System Interface, or SCSI, connectors provide a standard
system-level interface between a computer and an intelligent device, such as a hard disk,
floppy disk or CD-ROM and many others.
