S

CSI I/O devices are useful,
often powerful, and have some

of the best available data-transfer
rates. But they can be expensive,
too. And some of them, such as
tape drives and scanners, are
only used occasionally. Rather
than buying one for each user,
share them.

Our SCSI switches come in

several varieties that can switch
between different numbers of
SCSI buses. Choose from 2 x 2 or
4 x 2 Matrix Switches and 6 x 4
Electronic Switches.

These crosspoint switches

are transparent to your system
operation. That means they can
connect any bus on one “side” of
the switch to any bus on the other
side, with no delay and no need
for a SCSI ID.

You can use LCD-panel

menus, push buttons, and LEDs to
do monitoring and management

Key Features

SCSI MATRIX AND SCSI ELECTRONIC SWITCHES

from a switch’s front panel.
Menus serve a wide variety of
functions. They can be used to
switch or terminate SCSI ports,
display SCSI port status, enable or
disable daisychaining, number the
switches in a daisychain, display
the internal temperature, set a
maximum temperature limit, lock
or unlock the front panel, and
display the firmware version.

However, you’ll probably find

it more convenient to manage a
switch remotely by attaching it to
your LAN or to an administration
computer’s serial port. (The
switches include a serial cable
and adapter for this purpose.)
From an admin computer, you
can send ASCII commands that
duplicate all of a switch’s LCD
menu functions. Plus you can
send commands to set or report
alarm conditions, to report port
performance, to yank on the SCSI

reset line, or to lock or unlock the
computer’s serial port.

For complete convenience

and management, all SCSI Matrix
and Electronic Switches include a
CD-ROM of Windows

®

based GUI

control software that makes your
job even easier. You can replace
the ASCII commands with simple
radio buttons and checkboxes! 

The 2 x 2 Matrix Switches

support up to 32 peripherals.
If you think that’s a lot, check
out the 6 x 4 Electronic
Switches—they support up to 42
peripherals. And the 4 x 2 Matrix
Switches support as many as 60
peripherals! All models can be
daisychained through their serial
ports for larger or more complex
installations, or just for more
centralized control. LCD-panel
menus also set the serial ports’
data rate at 9600 bps or 19.2 kbps.
