Operation manual CTC-App

The simplest way to put CTC modules into operation is via the "Connect product" function. You can access this via the "Change config" button in the loco or switch box configuration (see previous page).

The configuration shown here is stored on the CTC module in two files:

• In the Config (cfg.xml), the functions that can be controlled via the app, such as lights, uncouplers, turnouts, signals, etc., are defined.
• In the IO-Config (ioCfg.xml), the input & output pins and interfaces configured for the CTC module are defined. Since these describe permanently installed parts on the CTC module, they cannot be changed via the dialog in the app.

The contents of the IO-Config are displayed under the heading "CTC-Module: Pins, Ports, Chips". All other displayed data comes from the Config.

Adding a product

To add a product, click the plus symbol to the right of the "Connected products" table. A list of product catalogs supplied with the CTC app will open.

You can select one of the supplied catalogs or load a product catalog from the file system using the "Select from file system" button. In this case, the supplied catalog "universell-weichen.xml" was selected and then "Apply" was clicked:

Now select the appropriate product. For some products, you can also choose from different configurations.

Then enter a name for the connected product and click "Apply".

Now you only need to specify which ports of the product are connected to which pins or ports of the CTC module:

1. The product you just added must be selected in the "Connected products" table. Then select the corresponding port of the CTC module in the "Pins, Ports and Extensions" table.
2. Use the "Test" button to check which pin of the connected product is connected to the selected port of the CTC module.
3. Then select the pin determined by the test in the "Connections and Parameters" table.
4. Click the "Connect" button to logically connect the pin of the product to the port of the CTC module.

Now you can see the created connection in the two tables "Pins, Ports and Extensions" and "Connections and Parameters":

Repeat the above four steps until all ports of the product are connected.

CAUTION: The CTC app ensures that the ports of the product can only be connected to compatible pins or ports. However, if you have selected the wrong product, this can definitely lead to damage to the CTC module and/or the product. This particularly applies to electromagnetic drives, such as those used in Märklin turnouts (whose end switches are not working). If these are connected as a switch (Switch) instead of as a pulse (Pulse), they will break after just a few seconds.
