NTI NODEMUX SERIES UNIVERSAL KVM SWITCH
15
FYI: If the Touch Screen Support option is present, the user can also exit the Main Command mode menu by tapping
once on "ESC-EXIT" on the screen, or by using a finger to align the cursor with a port number and removing the finger.
Aligning the cursor with a port and removing the finger will connect the user with the selected port in addition to exiting
Command Mode.
The mouse can also be used to control Command Mode. The mouse cursor can be moved to the Scan, Help, and Exit fields
where the user can then click on the left mouse button to perform that function. Ports listed on the screen can be selected by
moving the cursor onto that port and clicking. Clicking twice on a selected port will switch to that port and exit Command Mode.
To change the displayed ports on the screen simply click on the up and down arrows located to the right of the port names
displayed.
Note: The “port” mentioned in the command functions of Command Mode refers to the combination of the video (VIDEO
x) and device (CPU x) connections of like numbers that a CPU is connected to (i.e. the CPU that is connected to VIDEO
1 and CPU 1 will be identified as PORT 1 or P01). See Fig. 14.

Scan Mode
When in Command Mode, press < Ctrl>-<S> to toggle Scan Mode ON/OFF. The Command Mode main menu will indicate with
“SCAN-ON” or “SCAN-OFF”.
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. Also, the Command Mode main menu will show “SCAN - ON”. ) 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 above for configuring the scan
time-out period.
Note: The keyboard and mouse must remain idle for the full scan time-out period before the switch will connect to the
next active port.
Broadcast Mode
(use with extreme caution or commands intended for one CPU will be sent to all CPUs)
When in Command Mode, press <
Ctrl>-<B> to toggle Broadcast Mode ON/OFF. The Command Mode main menu will indicate
with “BROADCAST-ON” or “BROADCAST-OFF”.
Broadcast Mode allows the operator to send keystrokes to all active CPUs simultaneously (even those CPUs the user cannot
connect to due to lack of security access). Broadcast Mode is indicated by the illumination of the BROADCAST LED on the front
panel, and by “BROADCAST – ON” in the Command Mode main menu. The BROADCAST LED will remain ON while in
Broadcast Mode. However, Broadcast Mode has some critical requirements:
• BROADCAST LED must be OFF when booting any attached CPUs.
• BROADCAST LED must be ON and COMMAND LED must be OFF for keystrokes to reach attached CPUs.
Broadcast Mode is not supported by any ports that have MAC CPUs attached.
Normal Mode
When all of the NODEMUX mode LEDs are OFF the user is in Normal Mode, controlling the CPU to which the user is connected
through the NODEMUX.
