Re: Powerpax Booster voltage
toggle quoted messageShow quoted text
Terry, Mark, et. al.,
I found a “work around” for reading and writing CVs in a WOW121 version3 on a TCS motherboard.
I am using DecoderPro with a Digitrax DCS100 with a DCC Specialties PowerPax PTB. The “programming track” is equipped with a DPDT (center off) “Run/Program” selector switch.
If the capacitors are charged when the programming event starts, the PowerPax is able to keep the capacitors charged; I can read/write “Full Sheets” without any failures.
I keep the selector in “Run” until immediately before starting the programming sequence. I switch the selector to “Program;” then quickly (i.e. immediately) click on the appropriate DecoderPro “Read” or “Write” tab on the computer screen. I didn’t try an “All Sheets” read or write but have not reason to believe it would not work.
I was not successful when I tried without the PTB; the PowerPax made the difference.
FWIW – I tried this after thinking about Mark’s explanation of Paragon 2 programming difficulties on the NCE group.

Yes just this final mother board failed to read decoder type so i think my powerpax booster is
They you will very likely have a problem reading CV values from them. This is another well known problem that people discover latter when using KA’s.
What makes you think it is fried?
Have you tried reading a different decoder without a KA involved? Testing a programming track booster with a known good decoder that worked fine before is the fastest way to tell if it is working or not.
To answer you question about the voltage.
Have you attempted to measure the voltage using a Volt Meter in AC mode? The voltage will only appear when you are programming.
I suspect the voltage will be a bit less than the wall adapter voltage used to provide power to the PowerPax.
The only official way to answer that question accurately is to contact DCC specialties.
