Serial to usb on Kunkin KP184 electronic load

[interflexo]

I am looking into it as we speak. Supporting Win 7 in 2024 is getting messier every day. Microsoft dropped Win 7 support on 14 January 2020...

Done. I replaced the V1.0.82.0 64-bit setup installer. Please clean your browser cache before download. It might be troublesome to download an updated file you downloaded before without cleaning the browser cache. The 32-bit setup installer remains unchanged.

Tested KP184 Modbus 32-bit setup installer on Win 7 Home Premium 32-bit with all Windows updates.

Tested KP184 Modbus 32-bit and 64-bit setup installers on Win 7 Home Basic 64-bit with all Windows updates.

If you find any issues please drop me a line.

  Oh, thank you so much! I just restored an old laptop with a bunch of ports to control all sorts of devices... And it's impossible to put anything on this except Windows 7-32! The main advantage of the laptop is the presence of COM, LPT, USB 

[AlexMeln63]

why is mode switching blocked when connecting to the device via the port?

[AlexMeln63]

Through the top menu bar - the control is working

Also these three icons indicate and change test mode when clicked.

[AlexMeln63]

unfortunately, it was not possible to enable the latest version, it gives the following error:

On a new laptop with Win 10 x64 - it works

unfortunately, it was not possible to enable the latest version, it gives the following error:
 

What is the Windows version in this case? Do you have all the updates installed in this system?
I know it takes a long time to update but this is very important, there are more than 100 update fixes on top of a Win 7 SP1. Probably missing KB2533623 hotfix.

[AlexMeln63]

Windows 7 SP1 is installed, regarding the KB fix... I'll take a look. I will try to install the original version the final version of Windows 7 x32

[interflexo]

Windows 7 SP1 is not enough (I tested and got a similar error). You need all the >100 updates on top of it. You can leave it updating during the night.
It is not feasible to test one by one and determine which updates are really required.
Having the system updated is a precondition for testing any software.
List of updates on my Win 7 Home Ultimate 32-bit test system below (excluded the anti-virus related ones from the list).

I reinstalled Win 7 Pro 32, everything worked!!!!
Thanks, great!

[interflexo]

I am very glad to hear that.

[AlexMeln63]

I would like to buy a license, but we have problems paying in foreign currency abroad, and $ 30 is a lot of money for our course ...
freeware functions generally suit me at a minimum. Thanks again very much!

User_Manual


Changes:

1. New optional anti voltage dip strategy on battery capacity test. Tries to not interrupt the discharge test and restart electronic load when required where bad electric connections are at play. Used in an attempt to save a very long discharge test from aborting. Always check your electric connections before starting any test.

The KP184 unit may always cut the test short (turning the load OFF) if the voltage dips below the programmed test end voltage setting.

It is a good idea to use solid bolted connections on soldered ring connectors at both ends of the test power cables.

Avoid alligator clips of any kind at both test power cable ends (battery and KP184 binding posts).

Also avoid the usage of 4mm banana plugs at the KP184 binding posts. The 4mm banana jack hole on KP184 is a bit loose and do not provide the required good electric connection.

Bad electric connections will result in short voltage dips and voltage spikes caused by inductive flyback currents. This will mess up your data, test plot graph and cause a premature test ending leading to wasted time.

The optional anti voltage dip strategy measures and identifies fast voltage dips and tries to avoid a premature test end. If the electronic load turns the load OFF the software tries to restart the load ON.

The voltage dips are identified when the voltage drops below the programmed test end voltage with a slope below -70°. There is a maximum of 3 consecutive attempts to restart the electronic load, there is no limit for the non consecutive load restart attempts. This option can be enabled and disabled during the test progress.

Changes:

1. New “Plot Graph Annotations” sub menu. Added horizontal, vertical and crossed reference lines to the existing coordinate annotations.

2. New option added to select the color for annotations creation.

3. New option added to control the plot graph grid lines display.

4. New option added to control the plot graph title display.

5. New option added to control the transparent legend placement (9 options) on combined CSVs plot graphs.

6. New option added to control the current curve plot display on combined CSVs plot graphs.

7. Data acquisition and battery capacity test right mouse button context menus were dropped because the options are now all available on the main menu structure.

User_Manual


Changes:

1. On battery capacity test mode, solar panel test mode and cycle mode with plot option the manual data acquisition controls are disabled because they are automatically operated during the test progress. This eliminates some possible odd user manual operations.

2. When battery capacity/energy units (Ah/Wh) or plot curve line styles are changed the plot graph is updated even after the battery capacity test termination. A new battery capacity test report can be created using the new plot graph.

3. When special test mode (GEN/BAT/RES/CVL/CWL/CYC/SOL) changes the plot graph is updated with a new axis initialization.

4. The time the status bar line messages remain displayed is now user configurable between 2 and 10 seconds.
