Communication Issues

I have the USB cable attached but there is no “USB-Serial” COM Port connection available in the list of available
COM ports.

 Unplug the KNK from your computer. Go to this link and download the driver for the KNK Maxx.:
http://knkusa.com/resources/
 Once you have downloaded and installed the driver, reboot your computer. When your computer has
finished restarting, reconnect the KNK to your computer. You should get a pop-up that will finish the
installation. If you continue to have trouble, contact your KNK dealer or KNKUSA.

When I tried to cut, I got an error message that said: “Overlapped I/O Operation is in Progress”
 Verify the correct listing is selected in the Serial Port menu. With Bluetooth connections, try the other
port in the menu. Refer to the last part of Section 1.11.1 for the COM Ports expected with various
connections used.
 Verify that the USB cable or Serial Cable is securely plugged into your KNK and into the computer.

When I tried to cut, nothing happened, no error messages either.
 Make sure your cutter is online.
 Make sure you have KNK Maxx Air selected.

 Check the baud rate on the machine to make sure it matches what is selected in the window.

When I tried to cut, I receive an error message that said: “An error occurred when trying to communicate with
the target device. The semaphore timeout period has expired.”
 Something interfered with the transfer of the data via Bluetooth. Try cutting again. Make sure your
computer is still within range of the Maxx Air.

 The Latency Timer setting needs to be changed on the Com Port assignment. To do this, watch the
video called “Communication Fix” at this link: http://www.iloveknk.com/FreeVideos/Support/

I’ve reinstalled the driver and change the Latency Timer, but my computer keeps losing the connection to the
KNK.

 You may need to change the power settings for the USB ports. To do this, go to Windows Control
Panel>System and Security>Power Options. Click on Change Plan Settings and then Change
Advanced Power Settings. In the Advance Power Settings window, click on the + next to USB
Settings. Make sure the USB Selective suspend setting is Disabled.

 If the KNK still becomes disconnected, make sure you are using the latest plugin. These are available at
