I currently have a dc layout. I have decided I would like to automate it with detection and signalling. My understanding is the digitrax SE8C will work on dc layouts, but it needs a master (such as the BDL168) from something. Will BDl168 work with dc? I will also have computer control using one of programs. What I would like to see done is have working signals as well as being able to shut down trains to keep them from crashing into each other. I would like to know if what I want is possible with the digitrax products, or if I will have to make the jump to DCC sooner then my current plan.
Detection and signalling on a DC controlled layout can be done, but train control would be a bit more problematical. The SE8C is a fine interface, but it has little intelligence of its own. Detection inputs send messages via Loconet to a user provided computer that has the smarts required to set turnouts and signals, and messages are sent back via LocoNet to carry out the required actions. A Loconet interface is required to do this (either a Digitrax MS100 or a Locobuffer-USB from RR-cirkits). Computer software is also required (duh), with many folks using the JMRI freeware suite or RR & Co ($$) software. If you convert your train control to DCC, then the software can run the trains as well, but expect to spend a lot of time programming things on the computer.
I already have the computer software (forgot to add that part). I guess i'm not 100% sure on how all the stuff works. The SE8C only does signals. It has no detection properties of its own correct? Meaning that is what the BDL168 is for.
In addition to controlling signals, the SE8C can control up to 8 stall motor switch machines as well as detection section inputs that can be driven by >+5 VDC from external detectors (BD4 or similar), to generate LocoNet messages to the computer. Local controls (i.e. fascia mounted pushbuttons) can also be accomodated. See pages 20 & 21 of the SE8C manual. BDL168s can also be used to generate LocoNet detection messages, and are needed to support transponding.
Okay, that answer my question. I like to make sure I understand things correctly before attempting to use them.
My guess is I am going to have upgrade to DCC first. I was also looking into CTI. What would be a better choice for automating my layout (with dcc) (includes the signalling) Digitrax or CTI price wise. And which is the best choice for DCC. Soldering is not a concern of mine I have done circuit boards before.
I use both Digitrax and CTI. If you don't want to go with DCC then I would recommend you go with CTI. Their starter package is a great deal and includes software. Their system doesn't care if you are using DC or DCC. If you go with Digitrax you are looking at a lot of extra cost up front plus you will have to select a software package. JMRI offers freeware software but I have never used it. There is also Winlock, RR & Co, and KAM but they are all commercial packages with fairly high cost. David
I have had some experiance with RR & Co, but the price is a little high. CTI keeps looking better and better.
