Tim, I changed over from DC to DCC . I did buy your DCC Detectors. After I install them, is there anything else I will need before powering up your signal system ? What about the bias voltage that was applied to the DC track for detection ? Does that go away with the old detectors ? Joe
I would not use my detectors for DCC. They will have a problem with either false detecting or not detecting at all. There is a modification that I can do so that they may work on most layouts, but I will not sell them for new installations. I also am concerned with the DC power crossing over to the DCC power if the IC shorts. I have been successful in converting the detectors for DCC with existing layouts, and I will do yours for $4.00 each. I install a new pot, change the output transistor to a FET, and adjust the gain of the OP-AMP. Clean up the solder pads and return. What I suggest is to install DCC detectors from either NCE, DCC Specialties, or the DCOD’s from C/MRI. I carry all three if you decide to change to a different detector.
Let me know.

Tim, I worded my question wrong . I don’t mean your DC detectors, I bought a bunch of DCC Specialties detector from you. That is the one in question ! Joe

Will your signal controller work with Digitrax BDL168 detectors? That system has an LED output, so if you need to pull the signal to ground it would not be a direct link. Would an opto-isolator work for this? Any other suggestions?
The Digitraxx signal system works from a active high, which is opposite the industry standard. My signal drivers need a ground in order to work. You would need a signal inverter in order to use the ISS products. I have inverter board as part of my inventory if you wish to persue the signaling with ISS products. Please contact me at iss@netacc.net for more information.

Thanks Tim. I will e-mail you. I want to keep the signal and DCC system power supplies isolated from each other, so an inverting opto-isolator should do the job. Best regards.
