This is where we keep our download links for K-charts, Firmware, software etc. The links will take you to our server on Dropbox where we store all large files. Dropbox is a cloud system that provides server storage for companies to store large files. Small files can be sent via an attachment to an email message but large files (typically greater than 10 meg) cannot be sent this way so we upload our large files to the Dropbox cloud and by following the link that Dropbox gives to us for each file that we save on their server you are able to download the file from Dropbox. This service is completely free to you. Download speed will depend upon your own internet speed.

Tips and general stuff about using Onwa products under construction
Apart from providing links to download the files we also provide explanation, guidance, and tips that we feel may help you to complete the download process and also, where a software application may not be completely straightforward to use, some guidance through the process. If you are downloading files and software and you feel that an explanation is needed where it isn’t provided or that our explanation could be improved please message me, Alan Vick, either by way of a message on this website or by email to firstname.lastname@example.org. ‘Tips and other general stuff’ is something we will be developing so if you have any questions regarding using an Onwa product please let me know so that this can be included.
Downloading and installing the files.
Click the link button. You will be presented with a .tuf file (for firmware and charts). Download the file. In your downloads list see the file (note that you cannot open .tuf files as Window will not recognise them). Copy the file and save to an SD card, up to 16gb is OK. When saved, place into your plotters card reader. Power on the plotter and the update will be recognised before the plotter boots. Accept the upgrade and the file will load into your plotter. When completed switch off and remove the SD card.
FIRMWARE: this edition of firmware was released in December 2022
K-combo later G versions – check the serial no. of your ONWA KCombo-7, if after the model number, there is a letter G, then it is a G hardware Version. G versions have different sounder hardware. Be careful that you use the right K-combo version
Some versions of Mk3 and Mk4 KP1299 (all variants) may not accept an update to current firmware. If your 1299 Mk3 or 4 will not respond to the new firmware a small file is needed to be loaded into the plotter first before loading firmware.
Procedure: Download the small file to an SD card, put the SD card into the plotters’ card reader and start the plotter. File will be loaded. Proceed then with the actual firmware upgrade.
K-charts were introduced in 2018 as K-chart3.1 built in charts to replace K-chart2. The K3.1 charts are generally better for most areas than K-chart2. Unfortunately the size and complexity of the K-chart3.1 produced quite serious lag when used in 7 inch models. Kp38 and 39 particularly were slowed to the point where the plotters were difficult to use. K-combo and Kp708 versions with their better hardware were usable and KP1299 models with their very superior hardware and memory were OK. In 2022 there was an improvement in the design of the K-chart to version 3.2. This was in the form of a ‘tweak’ to the charts which improved the lag across the whole model range although for KP38 and KP39, whilst improved, it is still noticeable.
To activate K-chart3.2 requires a menu change – change map choice to K-shart3. If you have been using an SD card version of K-chart2 then you also must change map source to built in.
Here are the links for K-chart3.2:note that the area images covered by each chart is for version 3.1 and may be slightly smaller since the 3.2 change

How to program the 200A and 200AS, note that this procedure requires a serial to USB dongle that works – many don’t and the process will fail. This is why AVES Marine provides a free programming service to anyone who buys from us. We have serial dongles that work if you want to program your 200A/AS
