Page 14: Cascading
CASCADING The NTI ST-xU Universal KVM switch can be expanded to access up to 152 CPUs by cascading multiple units together. Up to 8 SUN, MAC, or Universal switches can be connected into an ST-xU Universal KVM switch’s CPU ports, as shown in Fig. 14. The NODEMUX connected to the monitor and input devices must be configured as the “MASTER”... -
Page 15: Configuration
Cascading is not available if the Touch-Screen Support option (page 25) is installed. Configuration All units are configured using switches 1 thru 6 of the 8-position dip-switch (located on the front of each unit) according to Tables 1 and 2. (Switches 7 and 8 are configured for the keyboard on page 5.) NOTE: Dip-switches are only found in legacy NODEMUX switches. -

Page 17: Operation
By pressing <Ctrl> + <`> (accent key), the user can enter Command Mode (either Basic, or OSD). Once in Command Mode, typing a series of commands will cause the Universal KVM switch to connect the user to any one CPU connected to the switch. -
Page 18: Figure 17- Video And Device Connections Identified With Port Numbers
FYI: If switches are cascaded (such as that illustrated in Fig. 14 on page 10), it will be necessary to make note of which port each CPU is connected to on each slave KVM switch and which port each slave KVM switch is connected to on the master KVM switch. -
Page 19: Scan Mode
Scan Mode When in Scan Mode the switch scans to each port with a CPU powered-ON. (The SCAN LED on the front panel will illuminate and remain ON while in Scan Mode. ) The port with the CPU powered-ON remains active while in use. When the switch becomes idle for the configured time-out period (default time out period is 5 seconds) the switch will connect to the next powered-ON CPU port. -

Page 22: Exit Switch Configuration Mode
In the event the setting is changed by mistake to "slave unit", to change it back to a "stand alone" switch, factory default settings must be restored via a terminal connected to the RS232 control port. See RS232 Control on page 26 for how to restore default settings. -
Page 23: User Name List
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH User Name List The User Name List 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. User names may be up to 12 characters long, may not contain spaces, and are not case sensitive. -
Page 24: Figure 22- Command Mode Menus
The On Screen Display menu will automatically appear on the monitor in addition to illuminating the indicator LEDs on the KVM switch. This provides a visual way to control the NODEMUX using the keyboard, monitor, and mouse. With Touch Screen support (optional), the OSD menu can be entered by tapping 3 times on the monitor. -

Figure 31- Switch Configuration Mode screen In the event the setting is changed from "stand alone" to "slave", when the switch is power cycled the OSD menu will no longer work. To restore the setting back to "stand alone", factory default settings must be restored via a terminal connected to the RS232 control port. -

(See Fig. 32). For each additional NODEMUX connected, another Matrix-Y-1 cable will be required. If the NODEMUX is one of two or more switches being controlled via RS232, and if the NODEMUX is not that last switch in the series of switches controlled, then this setting should be changed to "DISABLED". -

Page 36: Keyboard-To-Cpu Translation
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH KEYBOARD-TO-CPU TRANSLATION The NTI NODEMUX enables the mixture of otherwise incompatible devices and CPUs to control each other. It accomplishes this by performing keyboard-to-CPU translations automatically (i.e. connect a MAC keyboard and mouse to a PS/2 type CPU). The chart below shows the key commands that will be recognized and translated for the different types of CPUs. -
Page 37: How To Disable Operating Modes
Should it be necessary to replace the keyboard of one platform with a keyboard of a different platform, the dip-switches will need to be re-configured accordingly. To do this; 1. Power-down the ST-xU by following the proper power-down sequence. That is, turn the CPUs OFF first, then the NTI switch. -

The CPU does not sense activity while in the OSD menu. GENERAL NOTE: Verify that the port 1 LED (on the front panel of the KVM switch) illuminates when the power switch is turned ON. If it doesn’t, call NTI for assistance.
