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

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.) To enter Scan Mode press  from Command 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 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)
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 ). 
To enter Broadcast Mode press 
Broadcast Mode is
indicated by the illumination of the BROADCAST LED on the front panel. 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.
Normal Mode
 
When all of the KEEMUX mode LEDs are OFF the user is in Normal Mode, controlling the CPU to which the user is connected 
through the KEEMUX.
