SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER
7.Operation
7.1Keyboard and Mouse Emulation
The ServSwitch™ Brand CAT5 KVM and KVM/Serial/Audio Micro Extenders use 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 different CPUs to different Remote Units at different times in order to create a “switched” KVM-extension system. You can do this by moving cable between patch-panel ports or directly between Extender Units, although you should do this as infrequently as possible to avoid wearing out the connectors on your cable and devices. Or you can use a CAT5 switch, but the switch must carry all eight wires (maintaining the twists between the wire pairs) and must have enough bandwidth to support your system’s video demands. Please call Black Box Technical Support to discuss your application before installing such a system.
7.2 Normal Operation and Keyboard Typematic Rate
With the exception of the shared-access features of the Dual-Access model (see Sections 7.3.3 and 7.3.4), the Micro Extender should operate continuously and transparently, maintaining the long-distance connection between the local CPU or KVM switch and the remote user station or KVM switch. 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.
