NTI UNIMUX MULTI-USER KVM SWITCH USING THE NTI UNIMUX USB KVM SWITCH Basic Operation The UNIMUX switch enables a user or several users to access any CPU at any time. A CPU can be shared so that more than one user can use a CPU and work on the same project – each from their own console. Resolution is 1900x1200 with no degradation – guaranteed. The front panel LCD indicates the port to which each user is attached.
NTI UNIMUX MULTI-USER KVM SWITCH OSD CONTROL OSD superimposes a menu system on the user’s video screen with a list of all connected CPUs. OSD allows CPUs to be named (with up to 12 character names). OSD then allows selection of CPUs by that name. Connected CPUs can be listed by name or by port number. OSD Search Mode enables the user to type in the first few characters of the CPU's name and the OSD will locate it. HELP screens assist with all OSD functions.
NTI UNIMUX MULTI-USER KVM SWITCH Initial startup When the UNIMUX is first powered ON, a splash screen similar to the following will appear: Press any key and the UNIMUX will connect you to the first CPU port with a connected CPU that is powered ON.
