SERVSWITCH™ WIZARD MULTIMEDIA KVM EXTENDER
4.3 Configuring for a Serial Mouse
It is possible to connect a serial mouse and a CPU’s serial mouse port to the
Extender’s serial ports. If you do this, you must issue the hotkey command [H] [1]
[Enter] to force the Extender to use serial-mouse protocol unless the Extender is
still set to its factory-default configuration. This setting also forces 1200 bps, 8 data
bits, 1 stop bit, and no other handshaking (flow control)—it overrides all of the
Extender’s other RS-232 configuration settings (refer to
Section 5.11
for more
information about these).
We strongly recommend, however, that if you want to attach a CPU with a serial
mouse port, you use a PS/2 mouse cable (product code EVNPS03-MM) and PS/2
to RS-232 mouse-port adapter (product code FA314) to connect it to the
Extender’s PS/2 mouse port instead. This is because the Extender can emulate a
PS/2 mouse but can’t emulate a serial mouse, which becomes very important
during the PC’s boot process: A PC whose serial-mouse port is connected to the
Extender’s serial port might fail to boot properly if Unit B loses power or is
accidentally disconnected during bootup, which will never happen if you connect
the PC to the Extender’s PS/2 mouse port.
Refer to
Appendix B
for information about RS-232 cabling and for the pinout of
the Extender’s serial ports.
4.4 Setting a Password for the Extender
There are many situations where access to corporate file servers or sensitive
information needs to be controlled. In such circumstances, the ServSwitch Wizard
Multimedia KVM Extender’s Unit A and the attached CPU can be locked away in a
secure room or cabinet and controlled from the primary control station attached
to Unit B.
The Extender also has a password that you can set to prevent unauthorized use.
After setting a password, you can “lock” (disable) Unit B at any time by typing the
hotkey sequence together with the letter “L” at the primary keyboard: [Ctrl] + [Alt]
+ [L] if the hotkey sequence is set to its default value, for example. While Unit B is
locked, it doesn’t output video to the monitor or speakers or accept input from the
keyboard, mouse, or microphone, although the serial link remains enabled. The
Unit indicates that it’s locked by alternately flashing the Num Lock/Scroll Lock
LED pair and the Caps Lock LED on the attached primary keyboard. It can only be
unlocked if a user types in the password followed by [Enter] at the primary
keyboard. Locking Unit B has no effect on Unit A, so any control station attached
to Unit A should be secured in the same area as Unit A and its attached CPU.
