Hotkey commands

Hotkey command is a short keyboard sequence to select a computer, to activate computer scan, etc. The KVM switch interprets keystrokes for hotkeys all the time. A hotkey sequence starts with two left <CTRL> keystrokes followed by one or two more keystrokes. A built-in buzzer generates a high-pitch beep for correct hotkey command; otherwise, one low-pitch beep for error and the bad key sequence will not be forwarded to the selected computer.

The short form hotkey menu can be turned on as an OSD function (<F4>: more\Hotkey Menu) every time the left <CTRL> key is pressed twice.

L-CTRL: is the <CTRL> key located at the left side of the

keyboard.

1~8/A~H: are the number keys '1' ~ '8' at the upper row of the

keyboard and character keys 'A' ~ 'H' case insensitive. Do not use the keypad at the right of

the keyboard.

% To select a computer by hotkey command, you must know its port

number, which is determined by the KVM Switch connection. For a computer connected to a Master, the label of 1~8 or A~H represent its port. For a computer connected to a Slave, two characters represent its port. The first character is the port number of the Master unit (1~8) and the second one is the port number of the Slave (1~8 or A~H). Please note that only

Master's 'PC 1' ~'PC 8' ports can be connected to a Slave Left Ctrl + left Ctrl + 7 Selects a computer connected to port 7 of the Master. Left Ctrl + left Ctrl + 6 + C

-------------------- Cascade Configuration

Connection

Before connecting a device (a computer or a Slave KVM Switch) to a KVM Switch under power, you must turn off the device.

Note: The Master must have equal or more 'PC x' ports than that of the Slave, i.e., if an 8-port switch is the master, a 4-port or an 8-port switch can be a Slave, but not a 16-port one. PS/2-only models can be cascaded with USB-PS/2 combo models.

The ports labeled "PC 1"~”PC 8” can be connected to either a computer or a Slave's CONSOLE port, as shown in figure 10. The ports “PC A"~”PC H” can only be connected to computers.

Figure 11: All 4-port KVM Switches in cascade

The maximum number of computers controlled by a master/slave configuration with all 8-port units is 64 -- with 8 Slaves and each Slave connects to 8 computers, see figure 12.

Figure 10: Slave console connection

Note: Use only 1-to-3 (PS/2) cables for connection between the Master’s PC ports and a Slave’s CONSOLE port in cascade application.

The maximum number of computers controlled by a master/slave configuration with all 4-port units is 16 -- with 4 Slaves and each Slave connects to 4 computers, see figure 11.

Figure 12: All 8-port KVM Switches in cascade

The maximum number of computers controlled by a master/slave configuration with all 16-port units is 136 -- with 8 units of 16-port Slaves (to "PC 1"~”PC 8”) and each Slave connects to 16 computers;

LevelOne

plus 8 more computers directly connect to the Master (to "PC A"~”PC H”), see figure 13.

Figure 13: All 16-port KVM Switches in cascade

For OSD menu:

After connection completes, you should re-activate the OSD menu to check if the Master recognizes the Slaves. A triangle mark (!) is placed to the right of the channel name indicating the port is connected to a Slave not a computer. A number to the left of the triangle mark indicates the Slave model, i.e. 8! for an 8-port Switch.

Change Configuration while Running

A device (a computer or a KVM Switch) at any 'PC x' port can be changed at any time after initial power-up. If you change any one of the “PC 1” to “PC 8” ports connection from a computer to a Slave KVM switch or vice versa, or replace the devices of a port; the OSD

will update this change the next time it is activated.

Note: Any new device must be turned off before it is connected to the Master.
