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
0.2 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.

Appendix A: Troubleshooting
Appendix A. Troubleshooting
Make sure that all cables associated with each computer are well-seated and
labeled to avoid confusion when connected to the unit.
The unit has built-in power protection that works automatically when needed.
When it works, USB communication halts and the only way to restart the unit
properly is to remove all power sources (USB cables and power adapter), wait a
few seconds, then apply power sources, and start again.
A.1 Problems/Causes/Solutions
Symptom: Keyboard or mouse does not work.
Causes:
• In Auto Scan, keyboard and mouse are not operable (press Left-CTRL twice to
abort).
• Too many keyboards or mouse drivers are installed.
Solutions:
• Press any front-panel button to select a computer, then use the keyboard and
mouse.
• Remove all unnecessary keyboards and mouse drivers.
Symptom: Newly-installed USB device does not work.
Causes:
• Improper device driver.
• Device consumes too much power.
• Device consumes too much power instantaneously.
• Improper device initialization.
• When the unit works under self-power (that is, no power supply is added), it
supports a maximum of 100 mA as per USB specifications.
Solutions:
• Re-install the device driver.
• The device should be self-powered. Add a power adapter to the device.
Page 22
724-746-5500 | blackbox.com
Appendix A: Troubleshooting
• If the device does not have a power jack, add a power adapter with 9–12 VDC
and less that 1-A current rating to the unit.
• Make sure the USB cable is well-seated for good communications.
• Remove all power sources to the unit by unplugging all USB A–B cables and the
power adapter; then start all over again.
• Select the computer by push button, restart the computer, and try again.
Symptom: Computer hangs up while switching computers.
Causes: Device initialization or enumeration takes too much time.
Solutions:
• Wait at least five seconds before computer switching to ensure proper USB
communication.
• Turn off the device driver (not the keyboard or the mouse) before computer
switching.
Symptom: Auto Scan does not switch PC automatically, and the unit beeps.
Causes: All PCs are off or only one PC is turned on. Scan mode works for
powered-on computers only.
Solution: Turn on computers.
Symptom: No video signal when users plug and unplug the DisplayPort
connector or switch from port to port.
Cause: Some DVI video cards do not respond to the signal switch
simultaneously.
Solutions:
• Make sure that you have plugged a monitor to the console’s DVI port before
plugging/unplugging the PC’s video connector(s).
• Wait for a few seconds.
Page 23
724-746-5500 | blackbox.com
Appendix A: Troubleshooting
Symptom: The resolution is poor.
Cause: The unit’s video settings are not set properly
Solution: To adjust the optimal video strength corresponding to the length or
quality of the DVI cable, press the “FUNC” button combined with other push
buttons.
NOTE: The “FUNC” button is included only on the KV9634A.
Symptom: When switching between computer ports, the DVI monitor displays
“No Signal.”
Cause: Computer has gone into sleep mode or was not booted up while the
console was selected on that specific computer.
Solution: If the DVI video drivers are not installed, or are installed
incorrectly, the computer cannot be brought out of sleep mode by
using the keyboard and mouse. Also, when booting up a computer,
the respective port needs to be selected until the OS has fully booted
up. DisplayPort technology requires knowing exactly what is connected
when it initializes its video signal.
A.2 Contacting Black Box
