DCC Interface for the Booster Project (Video
Вставка
- Опубліковано 2 сер 2024
- Over the course of the last few weeks I made some good progress and I expect the booster to become available by the end of this year. In this video I am going to have closer look at the DCC interface part and how the booster communicates with the rest of the layout.

Hello Mr Tanner
I just wanted to say thank you very much for sharing all your knowledge and research on DCC you are a great resource and your teaching is very well explained and so easy to follow again thank you so much!!!! Happy new year 🎉
Thank you! I'm glad you like the videos. It's always fun to make them.
Thanks Hans - another brilliant video and another building block for us to play with! Cheers! Bill
Thank you!
Thanks for yet another video which presents with some interesting possibilities. Looking forward to what you come up with in your next video.
More to come! One small board on top of the stack, lots of new possibilities! I like modular designs!
@@IoTT Yes, that is one of the many things that I like about your designs.
Great stuff. I recently installed a 36 track turntable. I messed up on the stall track wiring so I would need a booster that has reversed polarity. Also knowing that the bridge track can show block occupancy would help me setup an automatic stall selection routine using loconet. Thanks.
Thank you. Yes, the booster will be able to do short circuit based AR as well as controlled AR using switch commands etc.
😅 Great stuff! Very interesting. Am I correct in thinking that the Loconet ports have power on 2 of the pins? ie you would connect this to the Loconet T bus along with other accessories such as throttles and occupancy detection as opposed to another Loconet power supply booster such as DIGIKEIJS Dr5033 which resides on a separate Loconet B bus which doesn’t carry power on 2 of the Loconet pins?
If you connect it to Loconet B it will pick up the DCC signal from pins 1 and 6 of Loconet. If you want to connect to Loconet T, you would have to cut wires 1 and 6 as they carry DC, and feed the DCC signal to the connector on the side. The booster can pick up commands either from Loconet or DCC, but whenb using DCC it is limited to switch and signal commands as that is what DCC supports. On Loconet, it also can read from block detector input and button input. Plus it can report short circuits and overloads to the network.
Hi Hans, I know you are in the middle of a move (hope it's going well) but any chances to post the Gerber files of the Tinkerface PCB over to your GitHub? That's the last piece of the puzzle!!
I should get my modem tomorrow, so I should have high speed internet again tomorrow or Thursday. I should then be able to upload it.
Hi Hans - I am using a Uhlenbrock Daisy 2 system with a Digikeijs DR5088RC and getting RailCom information back from my trains - will your booster connected to the Uhlenbrock systems accommodate RailCom? Thanks. Bill
It should replicate the cutout in the track signal and put a short circuit on the track so that railcom decoder can transmit the feedback bits. But it does not have a railcom receiver, so you need to have an additional receiver like with other boosters. I have no experience with Railcom, but based on what I studied, this should work. But of course it remains to be seen ;-)
Sorry - not totally with the terminology - would the DR5088RC be acting as the receiver………..
Yes. And the booster would take the role of the DR5033 Digiboost as shown on page 35 of the DR5088R manual drive.google.com/file/d/1-VFakeFs9OC0TfkCKBw7Mxn3ecfj_csf/view?pli=1
