What should be a no brainer for me, this is frustrating. Maybe I'm
really just getting too old for this!
The really helpful Wiring For DCC site says:
Solution for unterminated bus ends:
"The name of this problem suggests the solution - terminate your bus
ends. This is simple and inexpensive to do. Just put this "RC load"
at each end of your long buses. Yes, you will need two of these
circuits for each bus - one at each end."
I don't understand "you will need two of these circuits for each
bus - one at each end." Why two per bus and why one at each end? I
have a dangling end and can see that one, but the other end is to
the booster. So I need to put one across the booster output too?
And if so, then if I have 2 blocks with dangling ends, do I need 3 --
2 ends plus the booster? Or does the booster end need different
values?
Awhile back I asked about the type of cap to use and was told any
kind would work. The site also says they should be 50WVDC. Jameco
has Ceramic Disc Caps (+-20%) listed as 50V. Doesn't say AC or DC.
Are these OK? Their mylars also don't specify AC or DC.
Also, the components are listed with a range up to 50% greater. Is
it better to go to the low end or high end of the range?
And finally, I seem to recall someone, somewhere saying the 1/2 watt
resistors in HO were getting very hot. If that is true, isn't this
wasting power? Should I be using 1 watters?
Sorry for the many probably very easy questions, but this is my
first DCC layout and I want to do it right the first time, w/o smoke
or fire if possible.
Thank you for your help. Ken
