Al this may or not be new, but you may want to include it in the wiring peco Unifrog turnout section. The peco Unifrog has a wire to power the frog. The wire is not insulated and it is located very

Thomas, I’m new to all of this. The terminology I’m familiar with for powering track is main bus and feeds. Will the BD20 work properly with a feed where there are multiple feeds off of a main

Before starting my project, I set up a small test bed to make certain that I understood how to wire BD20s together with Atlas universal signal boards. The first thing it taught me was the

Notice what Alan said, ALL power for the track in the block must go through the BD20. I have three BD20 on the same module, about 3" apart on separate mainlines. Two work like a charm, one is always

Thanks, Blair. That seems like a solution. I'll have to reread the EasyDCC booster instructions. I think it says not to swap the two DCC signal pins to the booster. I don't know why that would be, if

Lighted rolling stock, passenger cars and other cars that need track power are a scourge to smooth operations. I am a curmudgeon, but when I weigh the need for lighted equipment on a layout that

Buy a creeper!

Do you have other BD20's connected to Atlas' universal signal control board in other areas of your layout that work? Just this one BD20 is not working?

Bill, The typical method for detection placement is for it to be on "the power to the block" rather than on "the power to one section of the block". I'll take the time to describe this further.

Definitely have 5 volts. On 9/27/21 10:24 AM, John Eldridge via groups.io wrote:

Thanks Bill, Based on your reply, confirming how this BD20 is connected, you said 3 wires: “one logic, one common, one power”. Have you measured the “power” voltage @ the BD20 terminals

Don, And yes, I realize you're not working with a Digitrax system, but the concept is the same. However the booster 'learns' what phase of signal to generate, you'll have to swap the

Don In the early days of DCC, I had problems with phasing on my Digitrax layout because I was sloppy with Telco vs Data cables. Since the only way to 'rephase' a Digitrax booster is to

John, I'm connecting the BD20s to Atlas' universal signal control board via three wires, one logic, one common, one power. the Atlas boards in turn have two other posts that use 5 volt

Hi Bill, Have been following this topic of your “Spacing between NCE BD20 detectors” question, and have some questions that I have not seen asked or answered. 1. Are you using a NCE AIU to

I have heard that adding a resistor to a freight car axle and/or caboose also helps with detection. Train length will dictate the number of resistors needed depending upon block length and

Don, I know that adding a 5-volt connection to posts 1 and 4 on a BD20 will permit the onboard LED to light or not depending on block traffic. I've also read, as you suggest, that it

I've connected up new EasyDCC boosters with auto reversing to my layout. Previously, I used a toggle switch on the panel to control the phasing of the power in the reversing loop. Auto reversing
