NTI NODEMUX SERIES UNIVERSAL KVM SWITCH INTRODUCTION The NTI ST-2U 2-PORT UNIVERSAL KVM Switch allows a single keyboard, monitor, and mouse to communicate directly with any two PC, MAC or SUN CPUs connected to the switch. These CPUs can be file servers, network managers, etc. The microprocessor driven circuitry in the NTI switch allows all CPUs to boot simultaneously without keyboard or mouse error.

NTI NODEMUX SERIES UNIVERSAL KVM SWITCH INSTALLATION 1. Turn OFF power to all CPUs that will be connected to the NTI ST-2U 2-Port Universal KVM Switch before connecting or disconnecting any cables to or from them. Warning! Damage to the CPU may result if power is not turned OFF before connecting or disconnecting cables. 2. Configure the ST-2U for the keyboard type being used as per Fig. 1 below (SUN, PS/2 or MAC).

NTI NODEMUX SERIES UNIVERSAL KVM SWITCH • MAC- Attach a MKTINT-xx-MM cable between the keyboard port of the CPU and a 8 pin miniDIN female "CPU x" port on the ST-2U switch. Using a 15DM-15HDF adapter, attach a VEXT-xx-MM cable between the video port on the CPU and a 15HD female "VIDEO x" port on the ST-2U switch. (See Fig. 8.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH WARNING! If a serial mouse port is being used on a PC to connect a serial CPU to an ST-2U switch, do not use a generic 9D-to-6mD adapter to make connection to the PS/2 cable-- use a VOPEX-IM9D to convert the signal from the serial port to PS/2. (See Fig.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH Units with touch screen support (optional) 1. Connect the 15HD male connector from a VGA multi-scan monitor to the port labeled MONITOR on the rear of the NTI ST-2UTS switch. If a touch-screen type monitor is being used, connect the 9D male serial connector from the touch-screen monitor to the port in the USER set labeled SERIAL on the rear of the NTI ST-2U-TS switch. (See Fig. 12.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH Power Up/Down POWER-UP SEQUENCE 1. Plug the jack at the cable end of the AC adapter into the ST-2U. 2. Plug the transformer end of the AC adapter into a power outlet. 3. Turn on the ST-2U. 4. Turn ON power to the monitor attached to the ST-2U. 5. Turn ON power to either or both CPUs attached to the ST-2U. POWER-DOWN SEQUENCE 1. Turn OFF power to either or both CPUs attached to the ST-2U. 2. Turn OFF power to the monitor attached to the ST-2U. 3.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH When the COMMAND LED is illuminated, all 3 LEDs on the numeric keypad of the keyboard will illuminate (if they aren't already due to CapsLock, NumLock, and ScrollLock) to indicate Command Mode is enabled and the following functions are available: (NOTE: The user must exit Command Mode in order to type to a CPU. To exit Command Mode, press the key.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH USB CPU SUPPORT (Optional) Introduction The NTI ST-2U-U UNIVERSAL KVM Switch has 2 additional female USB type B ports that allow USB compatible CPUs (SUN, MAC, or WINxx) to be connected to the switch. General Notes The ST-2U-U should have all cables attached before powering up. If no cable is plugged into either of the 8 pin miniDIN CPU ports labeled CPU 1 or CPU 2 (see Fig.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH PLEASE NOTE: It is necessary to configure a Sun CPU such that the Sleep Mode is not enabled. If a Sun CPU goes into sleep mode either automatically or manually, the user must reboot the Sun CPU in order to resume use of the Sun CPU. To disable the Sleep Mode, perform the following steps: 1. Select "Power Manager" 2. Look for "Device Idle Time Before Power Saving Starts" 3. Select "Always ON" 4. Look for "Override Device Idle Time For:" 5.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH Dipswitches The dipswitches located next to the RS232 connection (Fig. 8) are used to configure the baud rate and address of the NODEMUX. The default baud rate is 9600. The default address is 1. Use the charts below to change the baud rate and address as needed. OFF 12345678 ON Figure 17- RS232 Dipswitches BAUD RATE The baud rate can be changed by powering down the unit, changing the DIP switch, and then powering back up. This table shows how to set the baud rate.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH If Matrix Options is selected, the following menu, which has 7 options, is displayed: MATRIX OPTIONS 1. Reset single unit - reset single matrix to power-up defaults (not applicable) 2. Reset all units - reset all daisy chained matrix units (not applicable) 3. Change single output - connect an input to one output 4. Change all outputs - connect an input to all outputs 5. Read single output - read which input is connected to an output 6.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH AUDIO SUPPORT (Optional) Audio support provides the following additional features: • Audio signals from the same CPU that keyboard, mouse, and video signals are from can be received by the user. • Audio inputs accept any standard line level audio (1Vrms or 2.5Vp-p). • Audio outputs are capable of driving an 8 Ohm speaker load with 200mW of continuous RMS power.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH KEYBOARD-TO-CPU TRANSLATION The NTI ST-2U Universal KVM switch enables the connection of otherwise incompatible peripheral computer components to each other. This is accomplished by performing keyboard-to-CPU translations automatically (i.e. connect a MAC keyboard and mouse to a PS/2 type CPU). The charts below show the key commands that will be recognized and translated for the different types of CPUs.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH TROUBLESHOOTING If the ST-2U 2-Port Universal KVM switch is not working properly, consider the suggestions below to see if a solution can be found. • • • • Verify that all cables are securely connected. Verify that the CPU is connected to a Keyboard port and Video port with the same CPU port number. If a CPU seems to be locked up, press the “CPU SELECT” button a couple of times.
