Each ServSwitch Wizard MP uses a special “query code” to detect whether or not it
is connected in a cascade to another ServSwitch Wizard MP (or to a ServSwitch
Wizard MP LP, ServSwitch Wizard MP Pro, or ServSwitch Duo). By default, your
Wizard MP uses query code “AD” hex; this code should be fine for most
applications. However, older ServSwitch Duos with firmware versions earlier than
1.09 always use query code “EF” hex, and because it is essential that all of the
switches in a ServSwitch Wizard MP/Duo cascade use the same query code, you’ll
need to change the Wizard MP’s query code to “EF” if any of those older Duos are
hooked up to your cascade.

If any IBM PC compatible CPUs are attached to your ServSwitch Wizard MP, you
might want to consider how you want the Wizard MP to handle the mouse. In the
Wizard MP’s factory-default state, you can use a three-button PS/2 mouse or an
IntelliMouse to cycle through the Wizard MP’s CPU channels. To switch to the
next channel, simply hold down the center or “wheel” button on the mouse, then
press its left button. If you don’t want to use this feature—particularly if it’s going
to conflict with mouse-controlled application functions—you can disable it by
sending the [U][2], [U][3], or [U][5] command. If the third button on a three-
button mouse is being used to switch the Wizard MP, it won’t be available for use
with PC software, although the wheel on an IntelliMouse can be used for both
switching and software with no problems. For this reason, we’ve included the
[U][1], [U][2], and [U][4] command options, which cause the Wizard MP to
report to the attached PCs that they are attached to a 2-button mouse. If you want
to use all the functions of a 3-button mouse or IntelliMouse for your PC software,
you should send the Wizard MP the [U][3] or [U][5] command.
The ServSwitch Wizard MP supports “Internet mice” that are compatible with
the Microsoft IntelliMouse. These are fitted with a wheel or other type of scrolling
control and sometimes have additional buttons. Many such mice are available from
several different manufacturers.
You can connect either a standard PS/2 mouse or an IntelliMouse compatible
mouse to the Wizard MP’s control port. You can configure your CPUs using
Microsoft PS/2 or IntelliMouse drivers in any combination as required.
