AkkuMaster C4 device dialog introduction

The AkkuMaster C4 device dialog is to be used to view, adjust and gather data from AkkuMaster discharge and charge processes. It is possible to configure each outlet independent from the others. A configuration which overloads the charger is impossible, since the individual loads are accumulated and the resulting total current will be displayed.
Note : If a data gathering process is active, it is not possible to close the dialog. Each outlet channel may gather data in parallel and can be displayed individual. To switch between outlets will not been possible if device dialog is modal adjusted in application preferences.

A lot of hints are available by tool tips of the dialog itself and make this help nearly obsolete. The tool tips are visible by hovering the mouse over the fields of interest.

Version information

Afterwards the serial communication is configured using the device selection dialog the device version information is gathered in background while opening the dialog. This may lead into serial communication error, if the configured port can't be opened. The device dialog with the actual EPROM version from manufacturer is shown in picture 1 displaying version information.

Control recording

After selecting an outlet tab only the two radio buttons are active. Other senseless buttons are disabled for the moment.

Such a condition is shown in picture 2.

Gather data only

If, as usual, the charge/discharge process is started at the device, the selection of “Gather data only” the displayed process parameters are updated. Additionally the “Start” button gets activated to enable the start of the gathering process (picture 3).

After the start button is pushed all the graphics displays are updated by the gathering cycle. The stop button gets activated to enable stopping of the process for some cases. New data sets get created while the device switch between charge and discharge. The gathering process stops automatically if the device signals no activity anymore.

Note : Stopping the data gathering process will also stop the running process of the connected device for safety reasons!

Configured process

While using “Configured process” the data configuring the future process are updated with the actual values depending the the current adjusted values of the selected outlet. Afterwards you can modify the values according your choice. Since the program must be loaded into the devices EPROM before it can be executed the adjusted values are written into the selected memory.


Note : Since it is not possible to query data for the selected memory, I prefer to do all program configuration direct at the device and use “Data gather only” for data gathering.

If a memory index will be modified from which is red from the device the background of the combo box is colored the make this change more visible. Such a situation is shown in picture below.

To close the device dialog is only possible while no gathering processes are active. While closing the dialog the serial port is closed as well.
