4. The extender will operate with either shielded STP FTP or unshielded UTP CAT5 Se cable However correctly installed shielded cable is preferred especially in electrically noisy environments because it resists interference more strongly limits ground potential differences and reduces emissions To benefit from shielded cable the shield connection must be maintained from end to end through any intervening patch cables panels and RJ45 connectors Please note that shielded cable is advised in order to maintain regulatory EMC compliance Can the extender system be used between buildings No Ground loops could damage the extender system and attached equipment Can multiple Local Remote Units be used by swapping the interconnection cable Local Units provide full keyboard and mouse emulation so it is possible to swap or switch the local remote interconnection to create a KVM matrix switch system Sometimes you may need to reset the keyboard and mouse by entering the appropriate command after a swap or switch Please call Technical Support before deploying such a system Can the extender be connected into our network Absolutely not Regardless of the cable similarities the data signals and voltages used by the extender are different from those used by Ethernet and other types of networks Connecting the extender to a LAN hub switch repeater or other network device or exposing it to the signal levels present on network d
