Basic Operation
Manual Switching
There are three convenient methods to access the computers: Manual – which
involves pressing the port selection touch panel located on the unit’s front
panel; Mouse port-switching, and Hotkey – which involves entering
combinations from the keyboard. Hotkey port selection and Mouse portswitching are discussed in the next chapter.
For manual port selection:
Š To bring complete focus (audio, KVM, and USB) to a computer, either:
a) press the port selection touch panel that corresponds to that computer;
or: b) press the Mode touch panel once (the Mode touch panel three icons
flash) and then press the port selection touch panel that corresponds to that
computer. All three port icons light up.
Š To bring only the KVM focus to a computer, press the Mode touch panel
twice (the Mode touch panel KVM icon flashes), and then press the port
selection touch panel that corresponds to that computer. The port’s KVM
icon lights up.
Š To bring only the audio focus to a computer, press the Mode touch panel
three times (the Mode touch panel audio icon flashes), and then press the
port selection touch panel that corresponds to that computer. The port’s
audio icon lights up.
Š To bring only the USB focus to a computer, press the Mode touch panel
four times (the Mode touch panel USB icon flashes), and then press the
port selection touch panel that corresponds to that computer. The port’s
USB icon lights up.
Note: 1. Press and release either port selection touch panel to stop Auto
Scan Mode (See Auto Scanning, page 19). The KVM focus goes
to the computer attached to the corresponding port of the touch
panel you pressed.
2. If a port is not selected within five seconds of pushing the Mode
touch panel, the Mode touch panel will power off.

CS1942 / CS1944 User Manual
Hot Plugging
The CS1942 / CS1944 supports USB hot plugging – components can be
removed and added back into the installation by unplugging their cables from
the USB hub ports without the need to shut the unit down.
Powering Off and Restarting
If it becomes necessary to Power Off the unit, before starting it back up you
must do the following:
1. Shut down all the computers that are attached to the switch.
2. Unplug the switch’s power adapter cable.
3. Wait 10 seconds, then plug the switch’s power adapter cable back in.
4. After the switch is up, Power On the computers.
Port ID Numbering
Each KVM port on the CS1942 / CS1944 switch is assigned a port number (1
and 2 on the CS1942; 1, 2, 3, and 4 on the CS1944). The port numbers are
marked on the rear and side panels of the switch (see CS1942 / CS1944 Rear
View, page 8, for details).
The Port ID of a computer is derived from the KVM port number it is
connected to. For example, a computer connected to KVM port 2 has a Port ID
of 2.
The Port ID is used to specify which computer gets the KVM USB peripheral,
and audio focus with the Hotkey port selection method (see Port Switching,
page 17, for details).
16
Chapter 4
Keyboard Port Operation
The CS1942 / CS1944 provides an extensive, easy-to-use, hotkey function that
makes it convenient to control and configure your KVM installation from the
keyboard. Hotkeys provide asynchronous (independent) switching of the
KVM, USB hub and audio focus. If you wish, you can give one computer the
KVM console focus, another the USB hub focus and the other(s) the audio
focus.
Port Switching
All port switches begin with tapping the Scroll Lock key twice. The tables
below describe the actions that each combination performs.
Note: If using the Scroll Lock key conflicts with other programs running on
the computer, the Ctrl key can be used, instead. See Alternate Port
Switching Keys, page 21, for details.
