1 Introduction The NTI ST-nXm-U-HD (also known as NODEMUX-HD) is a multi-user / Universal Multi-Platform Matrix KVM switch, (n= numberof users, m= number of CPUs) with high density construction to require less rack space. It allows multiple users, up to 4, each witha keyboard, monitor, and mouse, to...

A cable for each CPU being connected to the switch: PS/2 CPU to Switch • VMTINT-xx-MM for video, keyboard and mouse interface OR SUN CPU to Switch • SMTINT-xx-MM for video, keyboard and mouse interface • 13W3M-15HDF ...
Page 7 - Additional Features
3 Additional Features • Users can work individually or share the same CPU. • Up to n users can work with m CPUs where n and m are the switch size acquired. • High density (similar to SCSI) input and output ports that interface cables plug into adapt to PS/2 and SUN platform devices. • Power cycle ci...
