Connecting ring wired to chimed doorbell

Help please. I have a ring wired doorbell and I am trying to connect it to my chimed doorbell. After trying a number of different options (bypassing the chime and changing which wire the doorbell connects to ) I think I need a transformer. I have bought the DIN rail transformer and connected it to the wires in my chime (completely bypassing the chime). There are 4 different thin cables so I have attached 1 to each of the 4 ports on the transformer but nothing works to power the doorbell. The wires all look the same and none look like a power cable but I understand it has a different power setting. I have tried changing where the wires go but none of the combinations work. The doorbell is connected to a different wire on each screw. Again there was no clear delineation between the different ports. What I am doing wrong? I probably need an electrian but though I could fix it myself. Thanks
