Presentation Applications
Another interesting use of KVM switches is for presentations that use data from several computer sources to
one or more monitors. NTI’s Video Matrix Switch allows up to 32 video sources to output to any or all of up
to eight monitors. This unit, which NTI builds to order, supports either 100 or 200MHz bandwidths and
resolutions through to 1900x1200 with no degradation.
Switch control is also made-to-order by NTI: infrared wireless remote, or RS232 (which requires a DIPswitch
configuration.)
The KVM switch unit uses output ports for up to eight monitors for presentation display. The unit also
contains the desired number of input ports (up to 32) for each computer that will send data to the presentation
monitors. NTI also installs the appropriate connector for the selected control method.
 For wired remote units, the presenter selects an output cluster that also indicates the input selection.
 For infrared remote units, the presenter first selects an output destination, then selects the input source.
 RS232 interface meets RS232C standards. Any host computer can control the system, but the program
must send an entire command line at once (not character by character). HyperTerminal in Windows does
not work with this system.
