Male Plug for 12 pin female connector on Aristo E8

General Discussion
#1

I am in the process of trying to use Aristo’s (Crest) Non-PNP board as a Motor Speed Control unit. This means that I will put a Pot (potentiometer) onto the Non-PNP board and use it WITHOUT putting the Radio Control unit on top of it, which is the normal way of using this non-PNP board. I am doing this as I want manual, non-RC, control of some of my battery cars. I know if I lose or break my RC transmitter (Train Engineer) I would be completely unable to run my many trains, except at 100% (full) battery power. This would be way too fast. I have waited over 6 month just to get the new Lithium Ion batteries from Aristo, I would hate to wait that long to get a replacement transmitter.

In order to use the non-PNP board this way, I think, in addition to the Pot, I will also need the male 12 pin plug similar to what you find on Aristo E8 DCC boards. Other newer Aristo engines probably have these same plugs. To insert an RC unit, a person MUST remove the 12 pin male plug. They either toss the plug or set them aside. If you have any of these plugs available, or know someone who does, I would like to purchase them for my unusual purpose. Thanks.

Okay, I’m confused! By non-PNP board do you mean the dummy board that comes plugged into the PNP socket?
You probably could get them directly from Aristo or one of the many folks who do RC or DCC installs.

For manual (or simple) battery power you could use either of these -

I didn’t name this board, that is the name that is on it, Non-PNP. It is primarily used for people who want to use battery/RC cars instead of plugging the RC board directly into the DCC board that is usually built into newer Aristo engines. I guess it is also for Engines that do not have the DCC boards. The Non-PNP board has an input pair of connectors labeled TRACK and output pair labeled Motor and, between these two is a three wire connector which is, I think, for the Pot, which is NOT provided. There is a large female 12 pin connector and, further south, another 8 or 10 pin female connector. The, sold seperately, RC board connects to these large two female connectors. The Aristo DCC board also has these same two large female connectors. There are also 2 fuses on the Non-pnp board, that is about it. Perhaps you are more familiar with the older Aristo system. I am talking about the newer system (2.4 ghz, I think it is sometimes called). Please excuse some of my nomenclature, I am no electrical engineer.

I am trying to get some info from Aristo, but I noticed that they have been forwarding my emails as the usual folks do not know much about this new RC stuff. Probably in the realm of Crest, the Aristo RC division.

Okay gotcha. You mean the non PNP board for the new Aristo Revolution TE system used for locos without the PNP socket.
The ultimate expert on the new TE is Dave Bodnar who you can get hold of through his website -

As far as I know there is no “Pot” available to control the motor speed that simply plugs into the pcb you describe.
There are manual speed control units available that use a pot to do what you want but they are part of an electronic circuit, not just a pot on its own.

You are right, the pot can not do it on its own. I have ordered a Motor Speed Control board for about $24 from China on eBay. It has a Pot connected to the board and is workable from 12 to 40 volts (my NiMH rechargables are 19.2 volts). When I was looking at this board I noticed the similarities of some of the components to the Aristo/Crest Non-PNP board. That board has a three wire connector for a Pot. So my goal it to get the Non-PNP board to work as a Motor Speed Control board. I have ordered a wide variety of Pots from All Electronics, to do some testing. I am pretty sure I need one of these 12 pin male plug connectors also, that all Aristo E8 unit have plugged into their DCC board, otherwise, I think, the wiring will not be complete.

Thanks for the link, I have emailed him.
