This installation guide fits for the three-way turnout 24630 from the C-Track range by Märklin:

It uses two of the drives 74490, 74491, or 74492, which feature a socket from the JST ZH connector system. On the CTC-Turnout Module with the item number WI-M-4L-C2, there are two cables with a matching connector.

Installing and connecting the CTC module

The CTC module is placed on one of the pins designated for the decoder (shown at the bottom right in the photo below) and pressed down. The other end of the CTC turnout module is fixed to the two drives with tape (shown at the very top in the photo).

Here’s how to connect the drive to the CTC turnout module:

• Insert the plugs of the cables soldered to the CTC turnout module into the turnout drives.
• Attach the cable lug on the brown cable to a tab labeled “0” (track).
• Attach the cable lug on the red cable to a tab labeled “B” (middle conductor).

The following image shows a right turnout with built-in turnout drives and a CTC turnout module.

Two IR balises can be connected to the four-pin socket of the turnout module. In the example in the photo, the four-pin socket was removed and the cables (red, blue, pink, grey) were soldered onto copper contacts on the track connection.

Register the CTC Module on Wi-Fi

If the CTC turnout module has not yet been registered on the model railway Wi-Fi, you need to do this first. You can find instructions for this in the user manual in Chapter 3.1 “Register Modules on Wi-Fi”.

Open Configuration

You can find a logged-in CTC turnout module 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 dialog, click on the plus button to the right of “Connected Products” to select what 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”:

Connecting the product

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

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

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

Proceed in exactly 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’s configuration:

The CTC turnout module will restart.

Turnout in the Control Panel

After a few seconds, the newly configured three-way turnout appears in the control panel:
