NTI NODEMUX SERIES UNIVERSAL KVM SWITCH OPERATION Control over the CPUs attached to the NODEMUX is achieved through operation of the NODEMUX. Once the NODEMUX is properly connected, the NODEMUX will enable a connection to be made between the CPUs attached to its "VIDEO x" and "CPU x" ports and the keyboard, monitor, and mouse attached to the "MONITOR" and "DEVICES" ports.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH Command Functions (Cont'd) Function: Keystroke: Toggle Scan Mode ON and OFF S Toggle Broadcast Mode ON and OFF B Sets scan time-out period for each port.

T P - (0-2) x (0-9) x (0-9) x - (0-9) x - (xxx from 002 to 255. ie. t002 would set the time-out period for 2 seconds) (0-9) x - (Pxx would be P01, P02, etc.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH 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. See Command Mode section on page 13 for configuring the scan time out period.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH When a standard user powers up the system a security screen may appear as setup by the administrator. The user will need to login to the system by following the instructions below for the USER LOGIN. If the user does not know the appropriate user name and password (setup by the administrator), contact the system administrator for this information.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH Switch Configuration Switch Configuration enables the administrator to configure the NODEMUX to be used as a stand alone switch or as one of the switches in a cascaded system. Switch Configuration is also used to setup the communication settings for RS232 communication with a remotely connected terminal through the RS232 port. For the Switch Configuration Mode menu, press from the Administration Mode menu (page 16). Be careful with this field.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH Note: After configuring an NODEMUX as a slave unit, when the power is cycled the slave NODEMUX will only be controllable through the master NODEMUX it is connected to. Direct OSD menu control of the slave unit will no longer be possible. 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.
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. Passwords may be up to 15 characters long, may not contain spaces, and are case sensitive.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH 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.

NTI NODEMUX SERIES UNIVERSAL KVM SWITCH Unit Address and Loop Back To allow multiple units to be controlled from a single terminal port, the RS232 control interface is designed to allow "daisy chaining" up to 15 units. By setting the appropriate RS232 dip switches, each unit can be given a unique address (1-15). Then the unit will only respond to commands on the bus if its address is embedded in the command. Use the table below to set the unit address.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH Loop Back In order for an RS232 command and a response to the command to be viewed at the terminal screen, the NODEMUX must have its Loop Back feature enabled. More than one NODEMUX may be connected to a terminal at a time. To do so, a Matrix-Y-1 cable (available from NTI) must be used. (See Fig. 32). For each additional NODEMUX connected, another Matrix-Y-1 cable will be required.

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.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH Keyboard Replacement 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. 2. Replace the keyboard. 3. Re-configure the switches (see Fig. 3 on page 5.) and then power up, following the proper power-up sequence.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH For models ST-xU (no OSD): 1. Make sure the ST-xU is completely disconnected from all CPU components. Be sure to unplug the ST-xU from the electrical outlet. 2. Remove the two philips-head screws from the underside of the ST-xU and set the ST-xU on a firm and flat surface, bottom down (see Fig. 37).
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH 6. Carefully loosen the video board from the standoffs. With it loosened, grasp firmly the video board and front panel at the same time and slide the front panel up out of the slots in the plastic case that support it. Once the panel is clear of the case, pivot the assembly back approximately 1", just enough to expose the jumper block. (See Fig. 39.) Be careful not to dislodge the connection of the ribbon connecting the LED board to the digital board.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH NOTE: Before proceeding, it is important to discharge any static charge you may be carrying by touching any large metal object (away from the ST-xU-O). 4. Firmly grasp the front and rear panel and slide the entire assembly out of the lower case. 5. Remove the jack screws from the video and monitor connectors on the rear panel. Remove the rear panel from the assembly. 6. The uppermost board is the video board.
NTI NODEMUX SERIES UNIVERSAL KVM SWITCH Configuring the Jumper Block Once the jumper block is exposed, apply a jumper across the appropriate pins to disable the desired mode(s) according to the chart below. Pin Designation Mode KCMD Command Mode* BRDC Broadcast Mode SCAN Scan Mode *Note: Putting a jumper across pins KCMD to disable Command Mode will also disable Broadcast and Scan Modes.
