This installation guide is suitable for the slimline crossover turnout 2275 from Märklin’s K-Track range. TODO image of crossover turnout

It uses two of the drives 7540, 75491. In this example, a 3-pin strip is soldered to the cables as a connector. On the CTC Turnout Module with the item number WI-M-4L-U, there are three cables to which a suitable socket was soldered in the example.

Installing and Connecting the CTC Module

The CTC module is installed on or under the model railway layout.

Here is how to connect the drive to the CTC turnout module:

• Plug the pin headers from the turnout drives into the sockets on the CTC turnout module.
• Connect the brown cable to the negative pole of the power supply or to the rail.
• Connect the red cable to the positive pole or to the other rail.

The following image shows the double-crossing turnout with attached turnout drives and CTC turnouts module.

Two IR balises can be connected to the four-pin socket.

Register the CTC Module with Wi-Fi

If the CTC turnout module has not been registered with the model railway Wi-Fi, you need to do this first. Instructions can be found in the operating manual in Chapter 3.1 “Register Modules with Wi-Fi”.

Open Configuration

A logged-in CTC turnout module can be found under its name in the module list in the CTC app. There, click on the pencil icon to open the “switch box configuration”.

There, click on the “Change Config” button:

Adding a Product

In the Config-dialogue, click on the plus button located to the right of “Connected Products” to select the type of product you have connected:

Select the product catalog “universal-turnouts” and then click on “Apply”:

Give your turnout a meaningful name and select the appropriate product and product configuration. Then click on “Apply”:

Connect the product

Now you need to specify which connections of the CTC module the turnout is connected to. The connector used above is soldered to “W1-green” and “W1-red”. You select “W1-green”:

Then you can check whether the turnout switches and in which direction by clicking on the “Test” button. In my example, W1-green switches to straight. Therefore, I now choose the line “straight” under “Connections and Parameters”. By clicking on “Connect”, you assign the connection “left” to the “W1-green: Output Pin #16” marked on the left:

Then in the same way, connect “W1-red” (Output Pin #17) to the “left-straight” connection:

Proceed the same way for the second drive as for the first.

Upload Configuration

Once all pins are connected, you can click the “Upload” button to save the changes to the CTC turnout module configuration:

The CTC turnout module will restart.

Turnout in the Control Panel

After a few seconds, the newly configured double crossover turnout appears in the control panel:
