Introduction Introduction The NTI ST-nXm-U-HD (also known as NODEMUX-HD) is a multi-user / Universal Multi-Platform Matrix KVM switch, (n= number of users, m= number of CPUs) with high density construction to require less rack space. It allows multiple users, up to 4, each with a keyboard, monitor, and mouse, to communicate directly with any PS/2 or SUN workstation connected to the switch. A single switch can connect to 16 CPUs or up to 256 CPUs when switches are cascaded.
Interface cables and adapters are not included and must be purchased separately.
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 circuit control allows the NTI switch to be powered OFF, then ON, at any time without affecting the attached CPUs.
Installation Installation Turn OFF power to all CPUs that will be connected to the NTI ST-nXm-U-HD switch before connecting or disconnecting any cables. 1. If using RS-232 Control see RS-232 section for more information. 2. Connect the monitors to the 15HD female connector ends of the VMTINT-xx or SMTINT-xx cables, depending upon what type of devices will be connected (PS/2 or SUN). See Fig. 1. 3.

Using the ST-nXm-U-HD Switch Using the ST-nXm-U-HD Switch Basic Operation This unit enables any user to access any CPU at any time with no restrictions or limitations. 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.
OSDControl Control OSD 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.
User Login Mode User Login Mode requires a user to login with a user name and password from the list created by the administrator. With security enabled, the user will be locked to the current CPU and the login screen will remain on the monitor until the user logs in.
Figure 4- Administration Mode Menu Function: Keystroke: Enter User Name List Mode U Selects the idle time in minutes T - Exit Administration Mode and return to previous mode (0-2) x (0-9) x - - (0-9) x (xxx from 002 to 255. ie. t002 would set the time out period for 2 minutes. 000 will disable it. ) Esc Port Status Mode Port Status mode enables the administrator to view extended status information about the port selected in Administration mode.
Administrator Password (cont'd) Function: Keystroke: Save new password. (The administrator will be prompted for a Yes or No confirmation) Enter Return to Administration Mode (If Password string and Verify Password string are different, this command will have no effect, enabling the administrator to correct the password) Esc User Name List To enter the User Name List press from the Administration Mode menu. The User Name List (see Fig. 6) enables the administrator to see a list of users.
User Access Functions Command Mode In order to control the switch with the keyboard, Command Mode must be enabled. To enable Command Mode from the keyboard: Press (ACCENT ~ Ctrl KEY) + ` All the status lights on the keyboard will illuminate to indicate that Command Mode is enabled. At this point, the Command Mode menu will be displayed. The Command Mode menu (see Fig. 7) lists all CPUs by name and port number. Only 8 ports are listed on the screen at a time.
Command Mode (Cont'd) Function: Keystroke: Enter Edit Mode (Only available if administrator is logged in) Ctrl + E Selects scan time in seconds Ctrl + T - Enter Maintenance Mode Ctrl + M Display Help Menu Select a specific port Ctrl Home Select the last port on the switch End Enter Search Mode, add a character to search string and select the CPU’s name that matches best. A-Z 0-9 Exit Command Mode - (0-9) x - (0-9) x - (0-9) x (xxx from 002 to 255. ie.
Edit Mode To activate Edit Mode press + from the Command Mode menu. Edit Mode allows only the administrator to modify the names of the CPUs connected to the switch. Names of CPUs can be up to 12 characters in length. Characters typed can be upper or lower case. After changes have been made the administrator will be prompted by the menu to save the changes. Answer "Y" to save changes and answer "N" to continue using previously entered port names.
Search Mode (cont'd) Function: Keystroke: Select the next port Add a character to the search string and select the best matching CPU name A-Z 0-9 Exit Search Mode, return to Command mode Esc (Type any alphabetical or numeric character) or Enter Maintenance Mode To enter Maintenance Mode (see Fig. 8) press + from the Command Mode menu. Maintenance Mode enables a user to customize the On Screen Display to their requirements.
Maintenance Mode (Cont'd) Function: Log current user out and return to User Login Mode. Save OSD window parameters for the port Return to Command Mode Keystroke: Q (Only displayed when security is active) Enter Esc NOTE: Based on different scan rates, the OSD window may appear in different areas of the monitor as different CPU ports are selected.
SUN’s Startup Keys With a Sun CPU attached to the switch, the following emergency startup keys are supported: Key Function Stop Bypass POST Stop-A Abort Stop-D Enter diagnostic mode Stop-F Enter Forth on TTYA instead of probing Stop-N Reset NVRAM contents to default values This switch will also support other startup commands not listed above.
RS232 Control RS232 Control Remote Connection The RS232 Interface is designed to control the switch via serial (RS232) daisy chain connection from any CPU or other controller with an RS232 communications port. There is, however, a restriction that must be followed: A program must be used that will send an entire command line all at once, not character by character. HyperTerminal program in WINDOWS cannot be used, as it sends each character one at a time.

Matrix Switcher's Control Program For Windows 9X, NT, and 2000 The Matrix Switcher's Control Program is an easy and powerful graphical program that controls NTI matrix switches through an RS232 interface. The Matrix Switcher's Control Program is on a 3-1/4" floppy disc packaged with the ST-nXm-U-HD switch. The Matrix Switcher's Control Program is installed by typing SETUP.EXE at the A:\ prompt. To install the Matrix Switcher's Control Program 1. At the DOS prompt, type A:\ and press 2.
ST-MX Expansion Units STMX Expansion Units In order to be able to expand the current ST-nXm-U-HD product or go beyond the 8/16 CPU limit on the ST-nXm-U-HD, the STMX expansion unit can be used to combine, or bank, multiple switches together to be controlled from one central workstation. Each user that desires to use the switch in this fashion will require a ST-MX-xx unit.
