Wow, I haven't looked at this thread for a while, assuming the forum would notify me of new posts and now I come back and everything is solved! Great job RhdZ!

I have been looking around for a good value electronic load and being able to log data on a computer has been an important criteria. More or less a showstopper if no software exists.
Reading about your software development Interflexo is really making me consider getting the Kunkin KP184. Amazing work, such a nice contribution to the community. If I end up getting the elecronic load, I will most definitely go through the registration of your software.

If you only want data from the load on your computer this software is good, but if you want more devices connected check: https://www.eevblog.com/forum/testgear/program-that-can-log-from-many-multimeters/, it supports many different loads and other devices.

Ok, very cool  8). Since I own a Uni-T UT61D multimeter and a Riden RD6006 power supply this software would also make a lot of sense to me. So many good option out there. Amazing forum really :)

Thanks. Kunkin KP184 panel operation and configuration menus are a bit cumbersome, the software allows a clear and straightforward operation with many extra features.

I am glad you worked it out Jasom.

You must always configure (baudrate and address) the software to match the operating panel menus configuration from your Kunkin.

I also had problems with higher baudrates.
Even when using a short cable and the com-port of the mainboard.

Best regards

New KP184 Software Version 1.0.22.0:

Changes:

1. Enhanced battery DCIR test. The first step may be configured to 0A to measure the battery internal resistance from an open circuit voltage (OCV) state. The step pulse time is configurable to meet specific user needs. Thanks adso85swe for the insight regarding DCIR test.

lnxpro I was not able to reproduce the same error on Win 10. You' ve got to help me here.
What is your OS version?
Is it a fresh installation or you are upgrading from a previous version? In the case of an upgrade, what was the last version?
I assume the configuration file is not found on the referenced folder. Have you confirmed it?
Anyone else found this problem?

tried a clean install of 1.0.23.0
same thing. the ini file is in the referenced folder (gets created during install), I can open it with notepad, etc.
I then installed version 1.0.21.0 back on top of the version .23 and version .21 works fine.
I also tried version .22 and it works fine. if I go to .23, it gives me the same error so for the time being I am back on version .22

Strange. I am running v.23 without any startup issues at all  ???

Dear lnxpro the issues regarding file names I think they are related to the new distribution format [multiple files (fast app load time)] vs [single exe file (slow app load time due to lots of unpacking at startup)] because there were no code changes related to these mishaps.

Please uninstall and try the version below, it is the same code on the previous working single exe file distribution format.

Please let me know how it works for you.

same issue with the onefile. says it fails to process the .ini file. this was on a clean install and the file gets created by the installer.
once again, version .22 works fine.

New KP184 Software Version 1.0.24.0:

Changes:

1. Back to one exe file distribution. Unpacked folder distribution causes problems accessing the .ini file. This will be sorted out later.

2. When a new configuration key was added to an older .ini file, example "inres_pulse_time2" from version 22 to 23 the error message "Can't access the .ini" was not adequate, there is a new popup message stating that one or more configuration keys were added.

lnxpro this should take care of your issues.

Hello interflexo. I know you have completely figured out the Kunkin protocol. I study it too. I cannot understand how the capacity value is converted. Can you help me understand this?

I get the following data from KunkinSW
01 03 1F 03 05 00 0D C1 00 07 D0 00 07 D0 00 FA 00 FA 00 07 D0 00 00 00 00 0A F0 00 09 C4 00 00 22 A3 C8 A6 1B
Where
00 09 C4 00 = ~ 0.178Ah
00 22 A3 C8 = ~ 0.63Wh
How are these values obtained? Normal HEX> DEC doesn't work. (I tried in windows calculator)

New KP184 Software Version 1.0.25.0:

Changes:

1. An optional Beep on load ON/OFF was added to the configuration page. Beeps are annoying but on remote operation it is nice to receive a notification when battery discharge is over.

The version: 1.0.25.0. Does not seem to work for me. I have a Ver:05 2020/12 Board.

However, 1.0.25.0 does work with my older 1801 Kunkin.

Additionally I am able to get the 2020 Kunkin to respond using My own C# Software and using HTerm by changing the CRC byte order.
