Karst: what do you mean by ‘ground’ in this instance? ?How is the capactior to be applied? (Just a guess… is the capacitor soldered such that it is connecting or bridging the two wires to the servo?).

Heath

Thanks for the reply.? The member who has the ProtoThrottle bought the ProtoThrottle Receiver for ESU CabControl, JMRI WiFi Throttle and Digitrax LNWI - MRBW-WiFi.? He has ESU CabControl at home.

We have successfully connected and used the following over our router to the LAN port and WiThrottle server on the YD7001:? UWT-100, UWT-50, Engine Driver on Android and WiThrottle on iPhone.? We have also used WlanMaus over the same router to LAN connection.? So I know the setup works.

As I said, I can tell that the MRBW-WiFi receiver is not connecting to the network - in the routers monitoring app I can see my cell phone and my UWT-50 connecting, but the MRBW-WiFi receiver does not connect to the network.

The member is going to contact Iowa Scaled Engineering to see if they have any ideas based on some photos he took, and if not what detailed debug info we an collect for them.

Thank you again for your response.? Jay Lennox - Toronto

The keyword here is: EMI or in laymen's language: Electromagnetic Interference. Which are kinda radio waves and cause noise to the Servo inputs by induction, like radio antennas receive their signal wireless.

Might be a small capacitor ( max. 10nF ) between signal and ground could help out, but better to find the root cause.

Thankyou, we have checked the back to back and all is fine. ? The strange thing is that the track power is not connected to the accessory bus so even if I short the tracks completely the servos do not move! ?

First of all I’m no expert but have used servos extensively for quite a few years now. The majority of these are on extension leads, most home made with the wire twisted together. The longest is around 4 meters long, most are between 1 and 3 meters long. This layout does not have any snubbers fitted and all is fine.?

As it’s just the one loco that is causing this problem I think you need to look for the problem with it. My guess would be that the wheel flanges are flashing across to the point blades or another part of the point causing the servo to twitch. Does this loco have deep flanges compared to the others. Also check the back to back dimensions. If the point is immediately after a curve this can lead to the wheels not straightening up and glancing the point blade causing a flash.?

Hope this might help.

Hi

One of our club members just received his Protothrottle.?

We are only using the LAN connection on the YD7001 to access it - the integrated WIFI on the YD7001 is turned off.? We followed the instructions to set up the Protothrottle's wireless adapter config.txt file to use withrottle, configured the SSID and password for the router, and the IP address and port number of the WiThrottle server on the YD7001.?

We cannot get the wireless adapter for the Protothrottle to connect to our wireless network and hence to the YD7001.? I cannot see the Protothrottle wireless adapter join our WIFI network (per the router monitoring software).? Note, our WIFI network for the train room is not connected to the internet, if someone thinks this could be our problem.

Thanks for any ideas

Thankyou fir your response, all the servos are connected with short wires but there are many other wires in the vicinity; track bus, accessory bus and 12v DC. As this o my occurs with 1 loco we are concerned that it may be a spike but confused because the track bus and accessory bus are not connected. Would you recommend bus snubbers on our track bus??

This problem is continuing so thought I should clarify the problem as no one has commented here.?

in summary I have:
Dr5000 controlling the accessory bus which is just for servo controlled points with DR4024 and some Peco SmartSwitches.?

Z21 controls main track and feedbacks.?

A loco passing over points will sometimes cause other servos on the same 4024 modules to move. This only occurs with one loco and only on ekectrifrog points. Frogs are controlled by 4024 via relays.?

continuity testing shows no continuity between the track bus and the accessory bus.?

Well... it depends...

?

Depends a.o. on what type of Pointmotors you are using.?

One thing is for sure: Without relay you'l blow away half of the internals of your YD8116..... ==> So NO, you can't.

?

Greets,

Karst

Can I use my YD8116 to control my frogs?
if so do I need to use a relay board such as the DR4102 in between!

diagram would be helpful please.?

Does anybody have one DR4018 for sale in the US? I am in Apex, NC. Thanks.

Hello

I am using DR4024s to control my points connected to a DR5000. The DR5000 is only controlling the points, locomotives and feedbacks are controlled by a Z21.?

The problem is when one specific (Heljan Class 52) locomotive travels over the points it causes the points to change (or sometimes the servos just twitch), often beyond the programmed positions. The DR5000 is not aware of the change so I suspect the problem lies in the DR 4024. The problem is repeated on another seperate part of the track linked to different DR4024 unit. The problem has not been observed on any of our insulated frog points or with any other locomotive.?

any suggestions appreciated.?

Brian and Karst

I just successfully updated the YD7001 and YD9401 firmware included in level 68.? The only major difference I can determine between my environment yours's? Brian is that I am on Windows 10

Here is my configuration:

• Laptop running Windows 10 22H2
• USB connection to YD7001

The update of YD7001 firmware was relatively quick - under 1 minute.? The update of the YD9401 firmware took much longer - about 2 minutes and 2 run throughs of the Update progress bar.? Then another minute or so to restart the YD9401.
??
I have connected a throttle and ran one loco.? I can report that the loco shows up in the slot table as In Use (click on Track Output on YD7001 picture and you will get the YD7001- DCC Properties window, then click on Slots tab).? Before the update the locos always showed up a Common when first acquired - In Use is the correct status when the loco is acquired from the TCS UWR-50 throttle.

I will do more testing over the net few days.

Might be you need to select YD7001 from the dropdown next to the Update button.

Karst,

Selecting YD7001 from the drop-down did the trick. All working now. Also updated the YD9401, all good

Question does F5 refresh also work on other screens like the slot screen.?

Thank you very much for responding on your holiday.?

Ok,

?

You managed to "brick" it on the previous try ?

?

But, since both STOP an GO are lit, it means the YD7001 is in Bootloader-Mode. So, directly go to "USB" and do the Update. Might be you need to select YD7001 from the dropdown next to the Update button.

Grtzz,

Jay,

Thanks for the response, so following your advice I have done the following:

Completely removed the YD7001 app and older DR5000 app, restarted and reinstalled the Build 68. Yes there were two driver installs. It all went well.

I then tried to reconnect to the YD7001 and the logging window just shows that no YD7001 is present and goes into Demo mode.?

I have checked that USB is selected as the connection method.?

I am using the same USB cable I have been using for the monitoring I have been doing. It has worked for for several connections over the last few weeks.

I am on Windows 11 Home build 22h2.?
The logging messages are:
device detected, when I plug the USB in.?
No YD7001 detected
Demo mode started

The YD7001 only has the Green and Red lights lit, and no responses on the USB LED when the USB cable is plugged in.

I was quite excited to test the new slot management changes.

Cheers

Brian

Hi Brian

My gut feel is that the install of level 68 on Windows somehow failed and you are dealing either with an old driver or a corrupt one.? ?When you installed the level 68, did you get prompted to install two drivers - one for the YD7001 and the other for the YD9401 (this is what I saw at our club, but I did not proceed to update the 2 firmwares as the YD7001 was being used during our operations night).? The driver is used to communicate between Windows and the device, and in this case it will be? a firmware chip on either the YD7001 or the YD9401. So I believe the problem is on the Windows side not the YD7001/YD9401. I have seen similar problems when upgrading the DR5000.

My first suggestion would be to completely uninstall the YD7001 software on the Windows PC.? Then install the software again and see if that corrects the problem - it did when I was dealing with the original DR5000.? I am not 100% sure this will work.

If the problem persists, I would think Karst will need to know:

• Level of Windows
• Whether you are using a USB connection (required for updates as I recall) or if the connection from the Windows PC to the YD70001 is over ethernet (LAN).
• What firmware you were trying to update - YD7001 or YD9401
• A complete capture of the messages you are seeing.

Since I have yet to upgrade the firmware on the YD7001/YD9401 I have no idea if I will run into a similar problem.

Let us know if uninstall followed by install fixes the problem.
