TROUBLESHOOTING FOR KPG-36X AND KPG-46X
This troubleshooting document helps you diagnose and resolve potential problems with your PC. Also, the document
addresses some of the more common problems previously experienced by KPG-36X or KPG-46X users.
If you do not find a solution to your problem in this document, contact technical support for further assistance.
Note: “PC” represents Personal Computer in this document.
For KPG-36X or KPG-46X, there is a switch to select between [USB] and [UART].
Which one do I select?
If KPG-36X or KPG-46X is connected to the NX-5000 series and the NX-3000 series,
switching to [USB] is recommended. (Also can be used even if [UART] is selected.)
For models other than the NX-5000 series and the NX-3000 series, refer to the user's
manual of the model and if no description related to switching between [USB] and
[UART] is found, use after switching to [UART].
Question
Answer
There are 2 drivers for installing. Which one do I use?
For KPG-36X or KPG-46X, there is a switch to select between [USB] and [UART].
If [UART] is selected, install "CP210x_VCP_Windows".
If [USB] is selected, install "Kenwood_Type_1_USB_Driver".
What do I do if KPG-36X or KPG-46X does not work properly on my PC?
Although the cause cannot be specified, the problem may be overcome by one of the
following methods.
●Solution 1
Make sure that the installation of KPG-36X or KPG-46X driver has completed
successfully.
●Solution 2
If there are multiple USB ports on the PC, connect KPG-36X or KPG-46X
to a different USB port. If a USB port on the front panel is used, connect
KPG-36X or KPG-46X to a USB port on the back panel
●Solution 3
If KPG-36X or KPG-46X does not work properly, restart Windows or disconnect
KPG-36X or KPG-46X from the USB port and re-connect it to the port.
●Solution 4
If any USB device other than KPG-36X or KPG-46X is connected to a USB
port, disconnect the device, and then re-connect KPG-36X or KPG-46X.
●Solution 5
If you have a USB hub with an external power supply, connect KPG-36X or
KPG-46X to the PC via the USB hub.
●Solution 6
If sliding the SW of KPG-36X or KPG-46X to [USB], the transceiver is not
recognized as a COM port if the transceiver is not turned ON.
Check again after turning the transceiver ON and then restarting the PC.
If the transceiver is still not recognized, slide the SW to [UART].

TROUBLESHOOTING FOR KPG-36X AND KPG-46X
How do I change the COM number for KPG-36X or KPG-46X.
Normally, a new COM number is automatically assigned to KPG-36X or KPG-46X in the
existing PC environment.
Depending on the PC, multiple communications ports for items such as a built-in
modem or an infrared device are available. In this case, the next available COM number
is assigned to KPG-36X or KPG-46X .
Follow the procedure below to change the automatically assigned COM number.
●Solution ( If sliding the SW of KPG-36X/ 46X to [UART] )
1. Start up the PC, and then make sure that Windows 7, Windows 8.1, or Windows 10
is properly running.
2. Make sure that the installation of the KPG-36X or KPG-46X driver has completed.
3. Connect KPG-36X or KPG-46X to a USB port on the PC.
4. For Windows 7: Click Windows "Start" button, and then click the "Search programs
or files" box. Enter “cmd.exe” by using a keyboard, right-click “cmd.exe” in the
searched program list, and then click “Run as Administrator”.
The command prompt starts.
For Windows 8.1, and Windows 10 : Right click Windows "Start" button, and
then click "Search". Enter “Command Prompt” by using a keyboard, right-
click “Command Prompt” in the searched program list, and then click “Run as
Administrator”.
The command prompt starts.
5. Enter the following commands and then start the Device Manager.
set devmgr_show_nonpresent_devices=1
cd c:\windows\system32
start devmgmt.msc
6. Right-click “Silicon Labs CP210x USB to UART Bridge (COMx)” in the Device
Manager > “Ports (COM & LPT)”, and then select “Properties”.
7. Click the Port Settings tab and then click the “Advanced” button.
8.
Select the desired COM port number from the COM Port Number dropdown list.
A COM port number with (in use), such as “COMx (in use)” cannot be selected
since the number is being used by another device. If a COM port number with
(in use) is selected, the message “This COM name is being used by another
device (such as another com port or modem). Using duplicate names can
lead to inaccessible devices and changed settings. Do you want to continue?”
appears.
If you wish to use a COM port number with (in use), make the number available by
disabling the device using the COM port number in advance.
9. Click the “OK” button.
Note:
◆If installation information on a device that no longer physically exists (or a modem
card that was installed before but is now disconnected) is retained, the COM port
assigned to the device may become “in use”.
◆The administrative privilege is required to do the above operations.

Is KPG-36X or KPG-46X equivalent to the serial cable (KPG-22A, KPG-36A, KPG-
43A, or KPG-46A) in terms of the time required for writing and reading data?
If sliding the SW of KPG-36X or KPG-46X to [USB], the time required for
communication depends largely on the PC used.
Also, it may take longer if the firmware is written by using KPG-36X or KPG-46X and
the corresponding Fpro (Version 6.30 or later) or KFL (Version 1.22 or later).
