WARNING!
If a serial mouse port is being used on a PC to connect a serial CPU to an NTI switch, do not use a generic 9D-to-6mD
adapter (Fig. 12) to make connection to the PS/2 cable-- use a VOPEX-IM9D (Fig. 13) to convert the signal from the serial port to PS/2.
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. Turn OFF power to the ST-2U 2-Port KVM Switch.
Using the NTI ST-2U 2-Port Universal KVM Switch
Control over the CPUs attached to the NTI ST-2U 2-Port Universal KVM switch is achieved through operation of the ST-2U 2-Port
Universal KVM switch. Once the ST-2U 2-Port Universal KVM switch is properly connected, the ST-2U 2-Port Universal KVM switch will
enable a connection to be made between the CPUs attached to its CPUx and DEVx ports and the keyboard, monitor, and mouse
attached to the MONITOR and USER ports. The lights on the control panel of the ST-2U 2-Port Universal KVM switch will illuminate
depending on which port (and subsequent associated CPU) is being connected to the keyboard, monitor, and mouse. The ST-2U 2-Port
Universal KVM switch can be operated by the front control panel or by keyboard control.
Front Panel Control
Pressing momentarily the “CPU SELECT” button on the front panel will toggle between CPU 1 and CPU 2 and connect the selected
CPU to the keyboard, monitor, and mouse.
Pressing and holding in the "CPU SELECT" button on the front panel for more than 2 seconds will cause the switch to cycle through
all modes of operation: COMMAND, SCAN, BROADCAST, and NORMAL modes. Release the button when the desired mode has been
selected. All three LEDs above the numeric keypad of your keyboard will illuminate to indicate that Command Mode is enabled. When the
LEDs resume their previous state of operation (LEDs illuminated only because CapsLock, NumLock, and/or ScrollLock are ON), the user
is in Normal Mode controlling directly the CPU to which the user is connected through the ST-2U 2-Port Universal KVM switch.
Keyboard Control
Keyboard control of the ST-2U 2 Port Universal KVM switch can be achieved through Command Mode. Command Mode is
operated by using keyboard commands as instructed under “Command Mode” on page 8. By pressing <Ctrl> + <`> (accent key), the
user can enter Command Mode. Once in Command Mode, typing a series of commands will cause the 2-Port Universal KVM switch to
connect the user to any one CPU connected to the switch. Pressing the <Esc> key will exit Command Mode.
