To be able to control the ServSwitch Duo from either of two separate locations at
any given time, you have to connect keyboards, monitors, and mice to both of the
Switch’s control ports, A and B. The Switch sends the video from the currently
selected computer to both monitors at the same time, but it will accept only one
source of keyboard and mouse data at a time, so only one of the control ports at a
time can be in active control. The other port is automatically disabled, although
the video continues to be displayed. This port can be given keyboard and mouse
control (that is, control can be “switched over”) when there has been no keyboard
or mouse activity on the currently active control port for a certain period of time,
called the “switchover timeout.” You can set the switchover timeout to any of seven
intervals, from 2 seconds to 10 minutes, using the “S” command (type
[S][digit][Enter]):
S1 Keyboard and mouse control can be switched over from control port A to
control port B, or vice versa, when the currently active port has been idle
for 2 seconds (default)
S2 5 seconds
S3 10 seconds
S4 30 seconds
S5 1 minute
S6 5 minutes
S7 10 minutes

WITCHING
In the ServSwitch Duo’s factory-default state, you can use a three-button PS/2
mouse or an IntelliMouse to cycle through the Switch’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 ServSwitch Duo, 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
ServSwitch Duo 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 Switch the [U][3] or [U][5] command.
