2. Introduction
About Your Switch
The switch you’re about to install is one of the best low-cost investments you can
make for your system. You’ll extend the life of your peripherals and add hours to
your work month with the time you eliminate in cabling and recabling.
The switch itself is one of the most durable devices you’ll ever own—the all-
mechanical operation and self-cleaning wiper action make for resistance to wear, a
very low failure rate, and years of life.
Our switches come in versions for nearly every connector on the market. If you
have any special requirements, such as unusual connector configurations or special
pinning, call us. We can get you a custom switch for your application.
Before You Install…
It’s easy to install your switch. The procedure is simple—it should be almost
instinctive for anyone who has ever hooked up a PC, VCR, or stereo system.
But there are a few things to be careful about. Before you start your installation,
check this list of cautions:
•Unplug everything. You should use the same care when installing your switch
that you use for connecting a PC or speaker. Although the switch doesn’t draw
current, your devices do, so unplug the power for all of them before you begin.
•Consider surge protection. The switch will not actively resist power surges, and can
pass along enough energy from a major surge to damage your data or equip-
ment. You might want the protection of an in-line surge protector. Call for
details on the surge protector that best fits your system.
•Don’t use a manual switch with laser printers. The delicate circuitry in any laser
printer could be damaged by the small amount of energy that any manual
switch passes. If you need a switch for a laser printer, ask about our electronic
switches.

3. Installation
Where to Put the Switch
The switch can be put almost anywhere. The site should be flat, dry, and stable,
and you should be able to reach the knob on the front easily. You don’t have to
worry much about airflow—the switch won’t get very hot.
Cables
You’ll need seven lengths of cable. Check your manufacturer’s specifications for
information on pinning—DTE-to-DTE connections, for example, will require
cross-pinned cable. Call us if you need cables. We can supply them for almost any
application.
All the switches, except the MMJ Switch (SW694A), are pinned straight through—
they don’t switch any leads during the passage of your signal. The MMJ Switch uses
a special cross-pinning scheme that lets you use your existing cables to make
connections.
Setting Up the Switch
Gather your cables and follow these steps:
1. Set your switch in the site you’ve chosen.
2. Turn off the power to all the devices you’ll connect to the switch.
3. Turn your switch around so that the connectors are facing you. The connector
marked “C” is the common connector. Run a cable from that connector to the
common device you wish to share with your multiple devices.
4. The other connectors on the rear—A, B, D, E, F, and G—are for the multiple
devices. Run cables from the connectors to those devices.
5. Check your configuration against the diagram on the next page. Add power to
your devices, activate one after another, and switch between them to check
your connections.
