4. Operation
4.1 Front Panel
4.1.1 LED Indicators
The LED turns green when the connected computer is powered on. Its
corresponding LED lights red when a connected computer is currently selected.
4.1.2 Push Buttons
For the KV9702A, press the “SELECT” button to switch PC port between the two
connected computers, and wait for 2–3 seconds after each PC port switching,
then you can press the button for switching PC port again.
For the KV9704A, each button on the front panel is associated with a connected
computer for selection. Press one of the buttons to select the connected
computer, and wait for 2–3 seconds after each port switching, then you can press
another button for switching PC port again.
4.1.3 Auto Scan
For the KV9704A model only, the system automatically scans through the active
computers in sequence with a fixed interval (see Scan Time in Section 4.1.4).
To activate Auto Scan, press front-panel push buttons “3” and “4"”simultaneous-
ly. The port LED flashes during Auto Scan. Auto Scan is effective for active com-
puters only. To exit the Auto Scan mode, just tap any one of the push buttons.
4.1.4 Scan Time
Set the scan time duration to 3, 8, 15, or 30 seconds.
For the KV9704A model only, to change the Scan Time, press both front-panel
buttons “1” and “2” simultaneously. The unit responds with beep(s) 1, 2, 3, or 4
times for Scan Time of 3, 8, 15 or 30 seconds respectively.
NOTE: Scan Time is set to 3 seconds by default after blackout or reboot.
4.2 Hotkey Commands
A Hotkey command is a short keyboard sequence used to select a computer,
activate a computer scan, etc. The KVM switch interprets keystrokes for hotkeys
all the time. A hotkey sequence starts with two left Ctrl keystrokes (successively in
0.9 seconds) followed by one or two more keystrokes. A built-in buzzer generates
a high-pitched beep for a correct hotkey command; otherwise, one low-pitched
beep is generated for error, and the bad key sequence will not be forwarded to
the selected computer.
