If you use a meter with peak or max recording that would show the current used or an analogue meter may show the peak.
I mounted one on top of a building and noticed when it flashed other LEDs on the layout dimmed slightly, maybe a high current pulse,
I now run it with a series resistor which changed the speed, but stopped the others dimming.

Have you got the correct polarity? DR4028 use a common +.

I can't answer your actual question but you can configure individual outputs on a DR4018 to flash an LED directly. Check the description of CV113 (and CV112) at the end of the DR4018 user guide. You'll probably have to set preset CV47=1 so that the DR4018 is controlling sixteen individual on/off devices.?

Hi,

Hi,

?

It's like this:

?

- YD6016LN provides a green heartbeat LED. As long as there is power and the module is not broken it will blink: ***.***. etc.? Frequency about 1 Hz. ( note that alle powered YaMoRC modules have this LED )

- YD6016ES provides a two green LED, one on IN and one on OUT.? Both flash rapidly when data is transmitted.

- all YD6016xx have a red activity LED which lights up ever brighter the more inputs are active

?

- DR4088LN provides a green(ish) LED that blink s with about 2Hz. when power is on and module is not broken.

- DR4088 have a red activity LED, that flashes for every occupied input from the module and/or any "upstream" modules

?

==> If a DR4088's activity light dos not flash, there are probably no active inputs.

Hi

I am using a DR 4018 to control signal lights, as these are common cathode I am using the Digikeijs adaptor (don't remember the code). All signals work correctly.

I have a level crossing and have fitted two very tiny LED's to the mast heads. The power for the LED's comes from a Green light contact from one signal.??
The LED's I am using are flashing type, they work perfectly from a battery but not from the adaptor. Replacing the flashing LED's with a standard LED works as expected.

Including the signal light the DR4018 is operating 5 LED's from one terminal. Each LED flashes independently, measuring the current from a battery is difficult as there is a random fluctuation of power.
? ? ? ?
Is there any reason the DR4018 / adaptor combination cannot operate flashing LED's?

All these conversations about LN and S88N modules has me concerned that all the wiring prep might not actually work once I power everything on. So here is my current question.?

I have two Digikeijs LN modules plugged into a 5097. Out of one LN module I have 3 S88N YaMoRC devices. Out of the other I have 2 S88N Digikeijs devices.?

When power to the command station is turned on, the status lights on the LN modules and the YaMoRC modules flash as if they are getting data. But there isn’t any flash from the Digikeijs S88N modules.?

I tried some cross plugging of network cables, but I could never get the Digikeijs S88N status lights to flash (except for a blip if I would plug on the data cable with power on)

Do I have an issue with my Digikeijs S88N modules or does the status light not continuously flash like the LN or YaMoRC modules.?

(If they are supposed to be flashing, any idea why they might not be?)

Thanks

Karst,
Many thanks for the answers. It is always good to find out accurate details. I am now confident that my design will work and have placed some orders.

One question that still remains in my mind - your image of the YD6016LN-CS acting as switch position feedback shows a 6.8K resistor faking an occupancy dectection of a locomotive. That's fine. I've been using that method on my Digitrax BDL168 to detect turnout positions and it works well.
The YD6016LN-GND version allows you to run a switch between the common and an input pin. I gather that is not possible with the YD6016LN-CS in turnout mode. I only ask that because there is a vid on YouTube implying I can wire the YD7016LN-CS also with a switch between common and an input.

Thanks again.

Hi,

?

LocoNet Feedback-Address-Space is 4096 addresses large.

That means in theory 42 of these units.... ( with 96 contacts each )

?

But please note: One should prevent getting the ES-Link buscables much longer than 1 meter ( 3ft ) in total from YD6016LN to the last YD6016ES connected.

?

As soon as the distance gets more than 1 - 1.5 meter (3-5ft) use another LocoNet YD6016LN and do the same trick.

Reason: LocoNet is meant for 300ft at least. ES-Link is not. We find 5ft is the limit. Others might find that conservative.?

?

Grtzz,

Hi Karst,
does that mean that I can have several of these LocoNet devices, each providing up to 96 feedback inputs? What's the limit then?

Greetings
Bernhard

Would it be sooo simple that the UR need th RailSync ??

?

You could connect the YD6016LN on USB to it's Config Software.?

?

Then watch the logging screen and issue a Power-On - Power-Off.? That should be shown in the Logging.

?

Greets,

Karst

Thank you. I'll keep trying!

* the ES-in versions still get their power from a LocoNET module closest to the command module. (YD7001 doesn't have an ES link connector)

Yes it does, but is in disguise ? it's the ext88N IN connector. Just use an RJ45 patch cable to the first ES-Module

* the unreleased RC version gets its power from the track since presumably it draws more than LocoNET can supply.

That's not the reason. Since it directly deals with high track current and -voltages, the LocoNet interface must be completely opto-isolated. So it's processor runs off the track connection, the LocoNet interface from the LocoNet-Bus.

* the main advantage of the ES versions is that I can configure several 6016 modules together with only one module needing to have a USB connection. (Ignoring the stick and Configuration module). So if I am prepared to configure each 6016 module on a computer before wiring it into the layout, then there is no need to have the ES wiring. The program button makes it even easier with no USB config required at all.

I urge you to specify the full article number. Only talking about 6016 makes no sense. YD6016LN and YD6016ES?are completely different animals.?So what you wrote does not make too much sense ?

* the GND version is used for switches - buttons or point motor feedback switches. But you could use a CS version in turnout mode. I haven't seen any examples of this online. To keep things less complex I could simply buy a CS instead of GND versions. There is a price difference but the CS is slightly more versatile should I need to re-design the layout.

Yes, it's only the electrical interface that is different.

Just made this sketch for a customer with an Z21 ?

Hi,

?

We got this question in our ticket system as well ?

?

Here is what I answered:?

Q: Before buying many YD6016LN and/or ES modules I need to know how many I can daisy chain on the LocoNET bus.?
A: LocoNet specifies a theoretical maximum of 47 devices on the bus. In Practice that means however that 40 is a good workable limit. Digitrax used to advertise that as well.

But... nowadays Digitrax advises to use a LNRP ( Repeater ) if the number of connected devices exceeds 20 ? ( maybe to sell repeaters ? )

That is why our solution with extendable LocoNet devices ( the YD6016LN series ) is so interesting.
One can see such a combo as one single LocoNet feedback device with a variable number of inputs.?
The base unit provides 16. every extra YD6016ES adds another sixteen, without counting as extra LocoNet device. So one can create a single LocoNet feedback with 16 upto 96 inputs !!

Q:Since the YD6016LN derives its power from LocoNET and subesquent ES modules appear to get power from the LN module it's a crucial piece of information.?
A: Our modules take about 25mA each. So it depends on the Command Station's LocoNet drive how many can be directly connected. Our YD7001 provides about 800mA hence a total of about 32 modules? (LN+ES) can be supplied with power.? For more modules, we advise the use of a so-called LocoNet supply. That is a device that injects another 1 Amp of 12V supply.

Q:?I also use several Digikeijs DR5097 LN hubs to provide multiple paths to serveral other LocoNET devices. So there is a lot of load on the LocoNET bus.
A: The DR5097 LN hubs are completely passive, so do not add to load.?

Unfortunately the part of the LocoNet docs do not include the specs for working with the UR92/92 ?

So we could not implement that feature.

Hi,

No messages or reports from other customer who have problems with it. For sure there are people out there using it successfully.

Thanks for your reply Dennis, I thought that would be the case I'll give it a go.

Matt?

Can you confirm that when you use the wired DT602D to acquire and control a loco that it still works when you then unplug the LocoNET cable?
