YaMoRC – There you have yet another model railroad company.

I’m going to get right to the point: Yes, I have a commercial interest in YaMoRC’s Digital technology. So then that’s out of the way, because my commercial interest is not what it seems. Those who know me a little know that I am a fan of many digital systems and certainly do not limit myself to any specific direction or manufacturer. And therein lies directly the heart of the importance: After all, I have to work with all these products. The wrong choice can result in a model layout that does not function to the customer’s liking. When I was asked to write an article about this new brand, I didn’t have to think very long about it. So I am writing this article about the brand more as a report on how I experienced the journey to the launch of YaMoRC, and how I slowly became a fan of the products. In this article, I will try to get you the YaMoRC products explained 🙂

Quality demand of YaMoRC digital engineering is paramount

As a layout builder, I automate model railroads of various scales with various digital systems. Whether a layout needs a hybrid Dinamo system, a Z21 with R-Bus or LocoNet, An EcoS, Intellibox or a Central Station with S88 modules. I don’t care which brand I use. My choice is partly determined by my hands-on experience with the products combined with the type of job I am building. And the products I use are from a variety of brands, brands that like me value support and quality. And as a “specialist,” you also need to be able to be broad in the systems you want to use. Especially since each brand has its own advantages and disadvantages. Each system strikes its own balance between Plug-and-Play and freedom. But for my feeling, in all the offerings on the market, I was missing a new sound, something that would bring a little stirring to the established order. Because let’s face it, there really hasn’t been much innovation for years.

This changed when, not entirely unknown to many, Karst Drenth introduced his new label YaMoRC. I was quickly triggered, because something beautiful could well come out of this. Karst is no stranger to me and we all know what can come out of his quiver. Consider, among others, the successful Rosoft and Digikeijs products designed by him. And if he decides to start developing, producing and selling under his own brand, we can’t help but experience something special.

Support and development

When I install or sell a system, I want to be able to rely on the knowledge of the person developing the products. This is a very important condition for me to work with a product. If we are at a loss for words, I want to rely on the fact that the manufacturer thinks with us and acts in a solution-oriented way towards us, and thus also towards the customer.
In the process of launching YaMoRC, I, inevitably, got wind of this new upcoming development and sought contact with Karst. Right at the first meeting I immediately noticed that my condition for support is not going to be a problem. Across from me sat a man who spoke passionately about his plans and products. It quickly became clear to me that he was serious about marketing a well-supported product line.

In the first interview I had, at his workshop in Apeldoorn, I certainly didn’t want to appear unprepared. So I had made a list of points from my own experience with digital systems and a top five problems from our help desk. During the conversation, however, I was able to cross out many of these points, as it turned out that they had already been incorporated by Karst into his designs. As many know, Karst is very active on various social media, and has listened carefully to the wishes, as well as complaints about existing products that users often bring up there.

Before visiting Apeldoorn, I had to hear it mostly. However, I myself am more of the first see, then believe, principle. I have since seen and “tasted” it, and my enthusiasm and confidence are anything but dashed!

During OnTraxs 2022, Karst launched Yet another ModelRailroad Company, or YaMoRC. But what are all these products? And why all the enthusiasm?
Now, read along and judge for yourself!

YaMoRC products explained

A brief description of what to expect from the YD8008 switching decoder! And in every way, this module is a revolution in model railroad engineering. Now you will think, yay, nice sales pitch! If you were at OnTraxs, the Digital Info Days, Houten Digitaal or in our store you may remember that we were abusing two magnetic coils.

In our demonstration module full of YaMoRC Digital technology, where we explain the YaMoRC products to you, we have mounted a Märklin, and a Fleischmann magnetic coil which is connected to the YD8008. Some already know this, but take this from me: These are real killers are for switch decoders. Often the outputs fail due to the high trip spikes or the drives bounce. For these to function properly and reliably, you then need to physically modify the drives. And so we didn’t, because Karst says his module can handle this! During the exhibition days, we subjected them to a duration test by having the module constantly switch both coils in succession, and we also asked passers-by to do the same. In a cycle of 30 circuits in a row that would cause other switching decoders to fail long ago.

Endurance test

Meanwhile, the coils and the YD8008 are still not defective and we can actually conclude that Karst’s claim is valid. This decoder is different from the rest. But how did this come about? Actually quite simple, through the use of buffering and timing.

First, the YD8008 buffers its energy. A lot of capacitors store the energy and once they are charged, the power supply is turned off and the buffered energy is used to switch the outputs. Each output can be loaded up to 9.5 amps, so even the heavy Solenoids from e.g. Peco, Gaugemaster and SEEP are not an issue for the YD8008. After switching the coil, the power supply opens again and the capacitors recharge. This way, the decoder never demands more than 380 mA from your power supply. You can therefore conclude that you can switch the entire model layout with a power supply of no more than 500 mA. This will immediately reduce the risk of fire hazards caused by using far too heavy power supplies for a model railroad!

Powerbank

Small note: If you have 10 and all 10 of them switch at the same time, you do consume 10x 380 mA and that 3.8A is then too much for a 500mA supply. So this beautiful freedom also has a small drawback. Which in addition is easily solved by setting on the central controller or software that there is a time between each switching command of c.a. 500 ms. So if you do that then you can expand indefinitely with a 500 mA adapter.

But this is not the only thing that causes this stability, as the module has something else that is new, something that no other switching decoder can do. And that is a variable pulse time from 5 to 1500 milliseconds on the output. By default, the setting is 30 ms, more than enough to energize each solenoid coil cleanly without it shooting through its final cutoff. I do have to admit that the OC32 can also do this, but personally I see that product as more of an all-purpose decoder than a plug-and-play decoder like the switch decoders.

A product which, in my opinion, manages to raise the bar for the competition quite a bit!
The YD8008 is a switching decoder for magnetic coils to which one can connect 8 coils. There is also a YD8044 that allows you to switch 4 magnet coils combined with 4 point piece polarizations.

YD8116 – Expanded switching in the latest generation

The YD8116 freedom in possibilities yet easy to use

I think this can somewhat describe the light and signal decoder YD8116. After all, is it a switch decoder, a signal decoder or a light decoder? It’s a little bit of everything actually. A decoder with 16 outputs that can be randomly set to a function of your choice.

Then you think nice the OC32 or the ESU Signal Pilot can do that too. Still, the YD8116 really does have something innovative, something that has been around for a while but has not yet been implemented by most manufacturers: DCCext. Another term you can’t do anything with …. Or is it? DCCext, also known as DCC Extension, is the new standard for switching decoders. Users of the OC32 know this as Aspects, multiple modes. A principle now also standardized applied in DCC standardization.

In the conventional system, each address had only two modes, red or green, on or off. If you had a signal with 3 or more colors, you had to start combining multiple addresses and modes. Unnecessarily difficult and complicated, plus you were consuming addresses you couldn’t use for anything else. DCCext makes this a lot easier with DCC aspects.

Aspect, another word for stances

Aspect comes from English and is a tricky term for stand, actually we talk about standings. Very simply explained, each address can be assigned 256 modes. The German departure signal (5 colors) no longer needs 3 addresses, but only 1 address. Hereby, each booth will have its own aspect, which will be included in the terminology as DCC Aspect. The next signal then just gets address 2 and so on. This keeps everything much clearer, and with the YD8116 this is possible!

It is also possible for a main and front signal combination to automatically turn the front signal to black. This is apparently also unique, never knew besides, this is usually controlled by the software. But besides signals, you can also use it to control small motors like the MTB MP1 or lights on the model railroad. In short, a beautifully beautiful product that is simple to program via any LocoNet module from YaMoRC or via the YD9100 USB interface.

YaMoRC YD6016 – Reporting, filters and triggers, the wonderful world of busy detectors

YD6016ES – The smart S88n busy signal module!

Perhaps the most intriguing aspect of automation: The busy signal and blocks. Important for me of course because I am still looking for a good busy indicator that I can use on very large model railroads. Previously, and even with my own DTS88n product line, we sometimes had challenges on very large layouts of over 100 blocks. Think ghost detection, sticky detectors in that trend. There was no really good LocoNet module, what there was gave a lot of interference. Only S88 was reasonably stable on larger numbers, which is why my choice often fell on block-controlled systems like Dinamo because here numbers are irrelevant. Until the arrival of YaMoRC’s YD6016 product line. For the first time I see a LocoNet module that I dare to deploy on the very large jobs as well!

How is that possible? Input filters! First in the market, on the YD6016 modules all inputs are filtered, both analog and digital with adjustable on and off delay, from inductive and capacitive interference and ordinary bad contact between wheel and rail. And this makes the LocoNet modules excellent to use even on long distances and with long track sections.

But there is another aspect that contributes to this. The YD6016LN is the LocoNet module, which in turn may receive 5x an S88n module, YD6016ES, as an extension. So you can expand any LocoNet module with 5x 16 outputs. A total of 96 outputs! This is very useful for making clusters. And thanks to the ES-LINK (more on that later), you also don’t have the hassle of patch cables and their potential interference.

Forms of busy signal:

We actually know occupancy detection in 3 forms:
CS: Current detection
Opto: Current detection modified with resistors for 3-Rail systems or switches
GND: Ground detection for 3-Rail systemsz

The latter GND, is ground detection on ground oriented control units such as the CS3, Intellibox and EcoS. This is not where YaMoRC’s priority will be right now because the future power station will be an H-Bridge power station and GND modules destroy the H-Bridge or themselves. For this, the first two modules are appropriate. Very curious, because actually they are functionally 1 and the same modules. Current sensing through the CS module we are familiar with mainly for 2-Rail, but if we provide those outputs with a 10k Ohm resistor we can also connect switches to them. And so also apply ground detection on 3-Rail model railroads where the wheels act as switches. We call this way “opto switching” because we misuse the optocouplers of current detection.

GND modules do exist from the YD6016LN line, but those are marketed specifically for using triggers and actions via switches. The YD6016LN-GND can be used for ground detection on a LocoNet Ground oriented central unit. The YD6016ES-GND breaks down when using the CS3 controllers. For using ground detection, we recommend using the DTS88n-GND modules!

Triggers and actions, reactions and consequence!

Nice and important you’ll think, but that certainly comes in handy. Because in addition to those filters and ES-LINK, the YD line has two more very important features.

First, it is possible to define the addresses for each input yourself. You can choose to traditionally number through, or you can assign each output its own unique address individually. This can be very useful e.g. when expanding an existing installation! And this applies to the LocoNet module YD6016LN but also to the YD6016ES S88 modules connected to it.

And the most fun feature, in my opinion, is an extremely unique and special option called triggers. And now in Dutch: switches. It is possible to connect a switch or push button to each input of the LN or ES. This on the CS modules with a resistor to imitate power consumption. The GND modules are most suitable for this purpose.

In the software you can set that this trigger should activate a digital change address to the central unit. Consider the switching of a turnout, signal or lighting. Now some will link directly to where I want to go, an old-fashioned switchboard! And that is correct. With the YD6016 line, it is possible to create an old-fashioned switchboard with toggle switches and push buttons in addition to tablet and computer control. And the best part is also immediately perhaps even more unique, the software gets what you are switching and will adopt it.

YD6016RB-CS - Especially for the white z21 users

You saw the term as briefly passing by. YaMoRC’s product line revolves around ES-LINK, the name of YaMoRC’s module connection protocol. In it, ES stands for: Extended S88. This is really nothing more than a physical and logical link between the modules so that they can communicate with each other. In itself, this is not very exciting or revolutionary. But conveniently, because Karst made it into two forms

ES-Bridge YD6901 is a small PCB that allows you to connect a module sideways to an adjacent module. To then assemble them neatly in a row. Sort of what Fleischmann used to do with those green switch boxes.

YD6902 - Perfect for porgramming decoders.

ES Adapter YD6902 is an RJ45 adapter to ES Link to link a module together via a Patch cable or a S88n port. And yes, the ES-Link does indeed work over the S88n port as well.

Via the ES-Link, it is also possible to program all connected modules from the software via a YD6016LN, YD6069LN or the YD9100 USB stick.

Just simple assembly, sturdy and reliability as we are used to from earlier times.

Software, something with computers

We are getting sick of it, again installing a lot of programs and of course you need another Windows PC for this. Karst is thinking about that too, as the desire to provide a software package that can work on all platforms has been prepared. But we have to be patient for a while longer!

In 2023, YaMoRC is planning its own configurator YD9101. A module that has a Wi-Fi module so that all connected modules can be accessed via the in the YD9101 web server. For whom I speak Latin now, you can then access and set up the desired module via the Internet browser. This is done without installing any further software or apps on your PC or phone/tablet.

Made in Europe

I expect my story has now clarified why I am so enthusiastic about YaMoRC’s products. We are at the dawn of a new era, a digital revolution in the model railroad market. A revolution that, like the CD-Rom and many other innovations, began with a company from the Netherlands. Call it a little patriotic glorification, but I can become quite proud when I see that by and large Dutch entrepreneurs are the ones trying to improve the market. Yes then I may have a commercial interest in this story and the brand, but I’m willing to put up with that because if something is good then it’s just good!

By the way, another thing that is not entirely unimportant to mention is that YaMoRC’s products are manufactured in Germany at a well-known and reputable company. No Chinese imports and production, just Made in Europe.

Future Vision

The future of YaMoRC looks bright. The designs are already ready for a digital power station, turntable control, reversing loop module, boosters and so on. The intention of YaMoRC is to offer a complete digital system at patriotic prices.

However, YaMoRC is also suffering from the global chip crisis, which is why it is not feasible to launch products in quick succession. As it stands, the digital power plant is expected in the first quarter of 2023.

Edit: Due to the bankruptcy of Digikeijs in April 2023, the demand for the products has increased so much that right now the priority is on the production of the existing modules. The novelties will therefore be produced later than originally thought.

YaMoRC has chosen to be fair in the market. Thus, sales will be done only by selected dealers. And with those dealers lies the obligation to keep prices fair, and provide the customer with the necessary support and assistance.
