Doorbell 2 Pro DIN Transformer Hardwired - Adding Doorbell Pro

I have just installed a **Ring Doorbell Pro 2** with the **hardwired DIN rail Transformer** and it all operates as it should over our Wi-Fi, with a plug-in Chime 2nd Gen, also over Wi-Fi. **I would like to know if I can connect a second older Doorbell Pro to the DIN Transformer directly or not?**My plan is to add this second doorbell at the rear of our property. It is an older but new **Ring Doorbell Pro** I already have, so my question is, can this be added to the same DIN transformer directly with a 0.75mm² two-core electrical cable over a 14 metre cable length? The current cable from the transformer to the Pro2 doorbell is about 1.2 metres in length. I have looked at All of the [wiring scenario options](https://support.ring.com/hc/en-us/articles/360022454432-Wiring-Diagrams-for-Ring-Video-Doorbell-Pro-Setup) on the Ring website and I see nothing that covers what I am attempting to do, probably because the product is newer?I get the impression from the existing diagrams that I need to install the older Doorbell Pro with the power pack at the end of the cable and in series with the +ve feed from the transformer but I'd like confirmation that this is the recommended set up for 2 mixed model doorbells on the same DIN transformer. If two Pro2 doorbells are use, would it be a direct connection then?Please illustrate these two scenarios in the list of wiring diagrams for future customer information.
