CHAPTER 7: Operation
7. Operation
7.1 Keyboard and Mouse Emulation
The ServSwitch™ Brand CAT5 KVM Micro Extender uses a microprocessor to
emulate the presence of a directly connected keyboard and mouse for the attached
PC. This means that you don’t have to connect a keyboard or mouse to the PC in
order for it to boot; in fact, the PC will boot with only the Local Unit connected.
This feature makes several other things possible:
• Your PC can operate continuously regardless of whether or not the Micro
Extender’s Remote Unit (or any local user equipment in a Dual-Access system)
is powered, connected, or even present.
• You can “hot-plug” or “hot-swap” keyboards and mice attached to the Extender
at any time; that is, you can unplug and replug the keyboard and mouse
without disrupting the operation of the PC.
• You can connect the Local Unit of one Micro Extender system to the Remote
Unit of a different Micro Extender system—effectively creating a KVM-
switching matrix—by swapping the systems’ interconnection cables. (We do
not recommend that you do this; if you feel that you need to, please call Black
Box for technical support first.)
7.2 Normal Operation and Keyboard Typematic Rate
The ServSwitch™ Brand CAT5 KVM Micro Extender should operate continuously
and transparently, maintaining the long-distance connection between the local
CPU or switch and the remote switch or monitor/keyboard/mouse user station.
Note that the remote keyboard’s typematic rate—the rate at which a held-down
character will repeat—is fixed at 30 characters per second, which is also the default
typematic value for Windows.
