Thank you Iain that makes sense.

Hi Jay,

Not 100% sure but that decoder might not like RailCom.?

Try turning off the cutout and see what happens.

Removed and reinstalled,? all fixed.

In this illustration from the DR5000 manual shows a DR5000 connected to a power district in conjunction with other DR5033 boosters. Therefore this is either inaccurate or the DR5033 differs from the DB210 Opto. somehow.
In which case what other boosters would be a replacement for the 5033, i.e. different to a DB210 Opto.

So can't use the DR5000 to power a district whenever using another booster, regardless that a DB210 OPTO not requiring ground (actually states not to). Great!

As for the DR5000 manual, to quote, what's this all about?
If more power is required, use a booster with an H-bridge at the output, such as the DR5033. Older boosters with a
common ground connection (e.g. M?rklin?, Uhlenbrock?) are not suitable and will cause short circuits and/or damage to the DR5000.

Yes as requested in the setup as it installed. wonder if its a driver problem? however it knows its there because it makes a noise when it connects.

Why do many have (need?) ground whilst the DB210 OPTO and DR5000 don't/can't?
From what I gather the OPTO bit is to allow DCC signals from another sources to be used without unpleasant things happening.
I intend to use LocoNet B to connect the DR5000 to the DB210. Apart from ensuring voltages between power districts are close I assume all will be good.

Thanks Alex,
I couldn't find anything about the DB210 being a H Bridge booster.
I noted the DB210 manual does mention not connecting ground for the OPTO version.
Then again I couldn't find a ground connection on the DR5000 anyway.

Out of curiosity what is the point of OPTO and the significance of H Bridge here?

DR5000 manual refers to optical isolation and H bridge but not sure what this actually means.
Would a DB210 OPTO Booster be compatible with the DR5000?
Want to check before possibly damaging either.

Hi

I just upgraded a DR5000 that run the layout in the train room? to a YD7001 using a YD9401.? After the upgrade everything works fine except for one loco, 5702, which will not respond to any commands - ring bell, sound whistle, go to speed step 10, etc.? 5702 ran fine with the DR5000 before I upgraded it.? What is interesting is that 5702 works just fine on our test track using an NCE PowerCab.? When the YD7001 is connected to the test track, 5702 will not respond.

To make sure it was not a DCC address issue, I renumbered another loco to 5702, and it works fine with both NCE and the YD7001.

5702 has a?QSI Steam - BLI Hudson 4-6-4 decoder according to DecoderPro.

Does anyone have any suggestion or experience with this type of problem?

Going back to this old topic of mine would the following work? and how would the addressing on the S88's work in this configuration? Excuse the rough sketch?

I've run across a baffling issue. Some time ago I installed a DR5013 as a reverse loop in current sensing mode, not short circuit. It has worked without issue until I installed a new Hornby TXS bluetooth sound decoder in a new locomotive.?

I have run many of my locomotives, sound equipped and not, through the reverse loop. I even added a layed up Hornby locomotive with TTS sound (an early Hornby sound decoder for those who may not be familiar). The issue occurrs only with the Hornby sound decoders, and only when the sound is turned on. What happens is the DR5013 goes into a short circuit condition and cuts the power to the loop. The red LED next to the reset button flashes until it's reset. If the locomotive is still present, the short will happen again as soon as throttle is applied.

I'm using a Roco Z21 base station and double booster - one booster is providing track power to the DR5013, and the 5013 is linked to the Z21 via Loconet. The 5013's short condition was sending a stop command to the Z21, which cut power to the whole layout, however I've fixed that by turning off the short forwarding from the 5013 to the Z21 via loconet (that's to Iain Morrison's suggestion on another forum). My next action will be to increase the short circuit delay in the 5013 and see if that helps.

I'm wondering if anyone else has encountered a similar problem, and if so, how they fixed it? My likely long term solution is to replace the 5013 with something better (maybe wait until the Yamorc version comes out - hopefully this year).?

Regards,
Jay M

You can have flashing and solid aspects if you use one of the signal configurations, but that will limit you to four signal heads per DR4018, I use NMBS as that gives me the aspects I use for US signals.
