This installation guide is suitable for the double cross turnouts 55224, 55424 from the A-Track program by Piko. TODO picture of cross turnouts

Both use two of the 55271 drives each. In the example, a 3-pin header is soldered to the cables: On the CTC-Turnout Module with the item number WI-M-4L-U there are three cables, to which a matching socket has been soldered in the example.

Installing and Connecting the CTC Module

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

This is how the drive is connected 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 the track.
• Connect the red cable to the positive pole or the other track.

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

Registering the CTC Module to Wi-Fi

If the CTC turnout module is not yet registered to the model railway Wi-Fi, you need to take care of this first. You can find instructions on how to do this in the operating manual in Chapter 3.1 “Registering the Module to Wi-Fi”.

Open Configuration

A registered CTC turnout module can be found under its name in the module list in the CTC app. There, click on the pencil symbol to open the “Switch Cabinet Configuration”.

There, click on the button “Change Config”:

Add Product

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

Select the product catalog “universell-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 Product

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

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

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

Handle the second drive in exactly the same fashion as the first drive.

Upload Configuration

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

The CTC-turnout module reboots.

Turnout in the Switch Panel

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