Before you begin  
Port Numbering  
Each CPU port on the KVM is assigned a port number (1, 2 for the GCS1802 and 1,2,3,4 for the  
GCS1804). The CPU port numbers are marked on the rear panel of the switch.  
The Port ID of a computer is the same as the CPU port number on the KVM. For example, a computer  
connected to CPU port 2 has a Port ID of 2. The Port ID is used to specify which computer gets the KVM,  
USB hub, and audio focus when using the Hotkey or OSD direct port selection method.  
Hot Plugging  
The KVM supports USB hot plugging – with no need to shut the unit down, components can be removed  
and added to the installation by unplugging or connecting their cables from the USB hub ports.  
16  
 
Power Off and Restart  
If it becomes necessary to Power Off the KVM, do the following:  
1. Power off the switch.  
Unplug the KVM cables from the switchs rear panel.  
Unplug the switchs power cable.  
2. Wait 10 seconds, then reconnect the KVM cables.  
3. Reconnect the switchs power adapter.

Scan Mode compliant keystrokes can be input. You must exit Auto Scan in order to regain normal  
control of the console. The audio and USB ports do not switch, but remain at the port in which Auto  
Scan was invoked  
Skip Mode  
This feature allows switching between computers to monitor them manually. You can dwell on a particular  
port for as long or as little as you like as opposed to Auto Scanning, which automatically switches after a  
xed interval. To invoke Skip, key in the following Hotkey combination:  
24  
 
1. [Scroll Lock] + [Scroll Lock] + [Arrow] Where [Arrow] refers to one of the Arrow keys. After you  
press [Arrow], you automatically enter Skip, you can switch ports as follows:  
Skips from the current port to the previous port.  
Skips from the current port to the next port.  
Skips from the current port to the last port (Port 4 on the GCS1804)  
Skips from the current port to the rst port (Port 1).  
Once you are in Skip, you can keep on skipping by pressing the Arrow keys. You do not have to use  
the [Scroll Lock] [Scroll Lock]combination again.  
While Skip is in effect, ordinary keyboard and mouse functions are suspended – only Skip compliant  
keystrokes can be input. You must exit Skip in order to regain normal control of the console.  
To exit Skip, press [Esc] or [Spacebar].
