SCSI I/O devices are useful, are often powerful, and have

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

Our SCSI switches come in several varieties that can switch

between different numbers of SCSI buses. Choose from one 
4 x 2 Matrix Switch and two 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, pushbuttons, and LEDs 

to monitor and manage 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 admin-
istration 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, 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 6 x 4 Electronic Switches support up to 42 peripherals.

And the 4 x 2 Matrix Switch supports 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.

The 4 x 2 Matrix Switch and 6 x 4 Electronic Switches come

with adhesive feet (for placing them on a desk or another 
flat surface) and rackmount hardware (for mounting them 
in a standard 19" equipment rack).

One unit is available that supports Single-Ended Narrow

and Wide SCSI.

By using a switch and its electronic switching circuits, 

you can electrically make or break connections between
groups of four and two independent SCSI buses.

All switching is transparent and no SCSI ID is required 

for the units. You can daisychain up to sixty 4 x 2 SCSI Matrix
Switches (SC122A-R2) and control them with one serial port.

Two units are available that support either Differential

Narrow and Wide SCSI or Single-Ended Narrow and Wide
SCSI.

By using a switch and its electronic switching circuits, 

you can electrically make or break connections between
groups of six and four independent SCSI buses.

You can also daisychain up to 42 of these switches

together and control them via 1 serial port. All switching 
is transparent, and no SCSI ID is required.
