NTI NODEMUX MULTI-USER UNIVERSAL KVM SWITCH RACK MOUNTING INSTRUCTIONS This NTI switch was designed to be directly mounted to a rack. It includes a mounting flange to make attachment easy. Install 4 cage nuts (supplied) to the rack in locations that line up with the holes (or slots) in the mounting flange on the NTI switch. Then secure the NTI switch to the rack using four #10-32 screws (supplied). Be sure to tighten all mounting screws securely.
NTI NODEMUX MULTI-USER UNIVERSAL KVM SWITCH INSTALLATION & CONFIGURATION Power OFF all CPUs that will be connected to the NTI Switch before connecting or disconnecting any cables. WARNING! CPUs may be damaged if cables are connected or disconnected while power is ON. 1. Connect the monitors to the ports labeled "MONITOR x" on the rear of the NODEMUX.
NTI NODEMUX MULTI-USER UNIVERSAL KVM SWITCH 2. Connect the keyboards to the ports labeled "USER x" on the rear of the NTI Switch. (See Figure 3) Use the proper interface cables. (See also Cable Selection Guide on page 10.) Insure that the monitors and related keyboards have the same port numbers. FYI: If it is desired for only a monitor to be connected to a set of user ports, an NTI keyboard cable (VKTINT-1 for example) must also be connected to the keyboard port for that user.
NTI NODEMUX MULTI-USER UNIVERSAL KVM SWITCH 4. Connect a VEXT-xx-MM (and adapter if needed) from the video port of the CPU to a port labeled "VIDEO x" on the NODEMUX with the same port number as the keyboard. Make sure the CPU is connected to a "CPU x" port and a "VIDEO x" port with the same number. Otherwise the user's typing may be going to one CPU, but the user will be viewing a different CPU on the monitor.

NTI NODEMUX MULTI-USER UNIVERSAL KVM SWITCH USING THE NTI NODEMUX UNIVERSAL KVM SWITCH Basic Operation The NODEMUX enables a user or several users to access any CPU at any time. Users can even share a CPU and work on the same project – each from their own console. Resolution is supported through 1900x1200 with no degradation – guaranteed. A Liquid Crystal Display (LCD) on the front panel indicates the port to which the user is attached.
NTI NODEMUX MULTI-USER UNIVERSAL 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 NODEMUX MULTI-USER UNIVERSAL KVM SWITCH OSD Modes Available With Security Enabled User Login User login mode requires a user to login with a user name and password from the list created by the Administrator. Key Alphanumeric Backspace Enter Esc Function Adds a character to the user name/password. Removes previous character from the user name/password Submit user name/password Exit USER LOGIN and return to previous mode. This function is only available if security is not currently active.
NTI NODEMUX MULTI-USER UNIVERSAL KVM SWITCH Port Status Port status mode (press from Administration mode menu) allows the administrator to view extended status information about the port selected in Administration mode. The information available here can also be found on the main COMMAND menu, except when multiple users are connected to a single CPU. In that event, while the main COMMAND menu simply lists the number of users connected, the specific users connected can be seen here.
NTI NODEMUX MULTI-USER UNIVERSAL KVM SWITCH User Name List The User name list (press from the Administration Options menu) displays the list of users and provides control for adding new users, changing or assigning user passwords, and changing access rights for any given user. The user names have a maximum size of 12 characters, may not include spaces, and are not case sensitive. The passwords have a maximum size of 15 characters, may not include spaces, and are case sensitive.
