4 pin decoders?

Postby End2end » Sat Sep 14, 2019 7:40 pm

Does anyone else make 4 pin DCC decoders the same dimensions / socket as a Hornby X9659?
It's to go in my new Hornby R3615 Peckett.

Not found one, but a chap on the other site used a smaller decoder than the hornby 4 pin version, hope this helps:

On reading further into this, it seems that the 4 pin socket is unique to Hornby, and the only decoder that will fit the socket is theirs, the alternative is to hardwire a different decoder.

Hornby at their most luddite. Really this loco should be update with a 6 pin socket now Hornby have accepted they exist even if their own attempt is largely, like their 4 pin decoder, their basic decoder fitted with a different plug

Thanks for the replies members.
It looks like the TCS M1 decoder, as per your link markS&D, could be hard wired. :)

I had a look and found the two Hornby R8125 4 pin decoders I have so I can test the loco (On DCC AFTER running it in on DC) but I really don't want one of these Hornby decoders in the loco permanently. They are, to put it bluntly...crap.

The price for a TCS M1 seems to be roughly around £36 including p & P although some places are out of stock.
Thanks

Yes, that was me! I used a TCS M1 but I also hooked it into the Hornby 4-pin 'blanking plug' so it could be removed or changed at some time in the future (possibly for sound).

Hornby are the only manufacturer doing the 4-pin decoder, but it is still the same decoder they use for the 8-pin installations, just with a different harness. The TCS M1 is smaller than the Hornby decoder so actually needed a spot of Blu-tack to hold it in place. Other small decoders that may be used include TCS Z2 or several CT Elektronik models.

Incidentally, I used this method for all three of my Pecketts and on a Hornby Sentinel diesel as well.

How did you fish out, clamp the wire and replace the pins in the Hornby blanking plate for the TCS M1 decoder please SRman?

The metal 'pins' in the blanking plug are retained by small plastic tabs that can be lifted slightly to release the pin -simply pull on the wire loop that's in it already, then de-solder the wire and attach the appropriate decoder wire, then re-insert the pin. the plastic tab should automatically click back behind the raised bit of the pin.

Thanks SRman. I'll give it a go when I get the decoder.

The TCS M1 decoder is now winging it's way to me.
I'd rather keep the original blanking plug that came with the loco but cannot for the life of me find the spare part number for the blanking plate to buy another.
Does anyone know the part number?
It's not on the info sheet that came with the loco. It only mentions the part number for the Hornby 4 pin decoder needed. :roll:
Thanks

A quick bump as I'm still looking for an answer to the question....... what is the part number for the 4 pin blanking plate by Hornby?
Thanks

You could ask Hornby or Peters Spares. Peters Spares might even have them. If you really are keen on getting one, I'll have a look and see if I have one... well I will if I haven't thrown them away. Let me know.

Thanks Peterm. I checked Peters Spares and they do sell them but temporarily out of stock.

If you do have one kicking around and are willing to let it go let me know how much you'd like for it. :)
Thanks

If this is what you're looking for, pm me your address and I'll send it over. It'll probably take a week to 10 days. No payment needed.

I used to buy them by the strip from Maplins, sadly no longer selling the sort of stuff I need. Finding them on RS, etc can be difficult, although they are there somewhere in the online catalogue.
