The SuperSwitch™ Advantage . . .
The SuperSwitch is a powerful and versatile, yet
low cost, microprocessor controlled switch. This
peripheral sharing unit interconnects up to nine
computers and peripherals using common serial
and parallel interfaces.
The SuperSwitch allows several computers or
terminals to have shared access to peripheral
devices, such as a printer, a plotter, a modem, or
host computer. Peripheral device selection is
done either automatically by sending data to the
default destination or by sending a code to select
a new destination. Any port may communicate to
any other port. Pairs of ports may communicate
simultaneously.
The units can be daisy-chained for expansion. The
versatility of the SuperSwitch makes it a practical
investment for the budget-conscious.
Connect up to 9 peripherals

Typical Application
Introduction SuperSwitch, a powerful, yet low-cost,
peripheral sharing unit interconnects up to nine computers
and peripherals using common serial and parallel
interfaces. Here are some of the features that make it a
practical investment for the budget-conscious.
Basic Concepts This versatile microprocessor controlled
switch has seven serial and two parallel ports for
connecting any combination of computers and
peripherals. Destinations are selected using an easy pop-
up menu, keyboard commands, batch files, or by other
ways. SuperSwitch activates the port connection when
you send data from your application or print program. Data
from each port is sent to its destination immediately if the
destination device is available. If the destination device is
busy, the data is queued by priority for its turn to access
the device.
Buffer Memory The SuperSwitch buffer is dynamically
allocated. As the data in the buffer is sent to its
destination, the buffer is reclaimed to be used again.
Allocating memory in this way protects against lockout
and ensures that large jobs always have adequate memory
available. It also maximizes productivity by returning
control of the computer to the operator faster and by
significantly reducing printing time. SuperSwitch’s 64K
buffer is expandable to 1Mb.
Cables You connect SuperSwitch to your equipment
using standard cabling with DB25 serial connectors and 36
pin female Centronics parallel connectors. Cables are
ordered by length and the type of device that is being
connected. Please refer to the cabling section for further
information.
Configuration SuperSwitch is configured through a PC
connected to port 0 using simple installation software
provided. A pop-up configuration menu displays setup
parameters for all ports and allows you to change them as
needed. You choose whether each port is to be connected
to a computer, printer, plotter, or modem. Other settings
for each port are its name, default destination, and priority.
For serial ports you also assign its communication
settings. Configuration is stored in the switch’s non-
volatile memory.
