KOS Update | :vokal, :kontroller, :konductor, DMI-KLANG

How do you want to update?

There are different ways to update new generation KLANG hardware. Choose your preference below.

Installing Update from a USB drive (default)

1. Prepare USB Drive

Any USB stick with 2 GB or more can be used. Plug the USB stick into

your Computer. Format it to a single FAT/FAT32 partition.

PLEASE SEE www.klang.com/format on how to format and partion.

2. Download KOS Update Files

Download Latest KOS for your product from here…

3. Copy KOS Update Files

Copy the two KOS update files to the USB stick’s root directory.

a) KLANG-00-CompletePackage-xx.yy.zz.KLANGupdate2 and

b) failsafe.ub

4. Initiate Update Procedure

Power off KLANG hardware.

Insert USB stick to USB port of KLANG hardware.

:vokal

Power on device WHILE pushing and holding the RESET/UPDATE button until Status LED switches from BLUE to WHITE (approx. 3 seconds).

The LED will blink and might change color a few times (approx 5-15 min).

Wait until Status LED turns to PURPLE.

DMI-KLANG

Power on device WHILE pushing and holding the RESET/UPDATE button until Status LED switches from BLUE to WHITE (approx. 3 seconds).

The LED will blink and might change color a few times (approx 5-15 min).

Wait until Status LED turns to PURPLE.

:kontroller

Power on device WHILE holding down the CONFIG button until displays

indicate update process. Wait for progress until device has booted.

:konductor

Power on device WHILE pushing and holding the RESET/UPDATE button until display indicates KOS USB update procedure (approx. 3 seconds).

The display will show the progress and might change color a few times (approx 5-15 min).

Wait until device has fully booted.

Over-the-Air (OTA) Update from Internet

First make sure the device you want to update is at least running KOS 5.1.x. If the KOS version installed is older than KOS 5.1.x, the only way to update the KOS is via USB.

Login with KLANG:app to the device.

Go to CONFIG > INFO > SET > Update Firmware from Web to…

Enter the serial number of the device and click OK to proceed.

Check the progress of the download process in the INFO screen.

The device will then reboot automatically, install the update and reboot with the new KOS version.

Update :kontroller to KOS of a Processor (PULL)

First make sure the device you want to update is at least running KOS 5.1.x. If the KOS version installed is older than KOS 5.1.x, the only way to update the KOS is via USB.

For :fabrik and :vier, download the :kontroller KOS version and copy both update files to an empty USB drive as if you would perform a USB update. Insert this USB drive into :fabrik and :vier and then :kontroller can download from there.

Login with KLANG:app to :kontroller

Go to CONFIG > INFO > SET > Update KOS to match

Check the the download progress in the INFO screen.

The device will then reboot automatically, install the update and reboot with the new KOS version.

Auto Update :kontroller to KOS of a Processor (PUSH)

First make sure the device you want to update is at least running KOS 5.1.x. If the KOS version installed is older than KOS 5.1.x, the only way to update the KOS is via USB.

Connect a :kontroller to a :vokal, :konductor or DMI-KLANG and :kontroller can access the KOS version installed on that device. The :kontrollers need to be logged in to a mix of the processor for the auto update procedure.

Login with KLANG:app to the processor.

Go to CONFIG > INFO > SET > Enable Kontroller Auto Update

All :kontrollers logged into a mix on this processor will perform an update if the KOS version on the processor is newer than the KOS version currently installed on the :kontroller. Depending on the number of :kontrollers on the network the download process might take a while and :kontrollers might retry to update if a previous attempt was not successful.

The processor will push the update to all :kontrollers until the processor is rebooted.


Something went wrong – Troubleshooting

Here are some tips and tricks if the update procedure does not start right away.

If KOS 5.1 or later is installed on the device already, there is a detailed LED color sequence (DMI-KLANG, :vokal) during the update phase, to help troubleshoot. The color changes a first time when the button press is detected from blue to white, a next time when a USB drive was successfully detected from white to yellow and a third time when the update files were detected on the USB drive from yellow to cyan (light blue). During the update the LED flashes white with different speeds. On :kontroller and :konductor the progress is shown on the display.

Prior to KOS 5.1 the LED color changes a first time from BLUE to WHITE when the button press is detected. During the update the LED flashes white with different speeds. On :kontroller and :konductor the progress is shown on the display.

The LED will directly turn orange and then purple if the update attempt failed and it will boot the currently installed KOS instead.

Make sure that you use a thin object with a diameter smaller than 3mm to push the recessed Update/Reset Button and that you feel the button click.

Check USB drive in KOS. Let the KLANG processor fully boot. Connect with KLANG:app to it and go to CONFIG > INFO > Copy LOG to USB. Carefully check the overlay message if the transfer to USB was successful or not. If it was successful it means the USB drive works in KOS and it is very likely to work well during the update. If the transfer was not successful, see below.

Try a different USB drive. Use another drive with a size between 4-16 GB. Not all USB drives behave identical so it is worth trying different ones. Check if it works in KOS (see step above).

Check format and especially the partition of the USB drive. Details here…
