Having almost recovered from the shock of ordering a new kitchen last week I can reveal that having not only ordered it but afterwards having also gone grocery shopping with Mrs. Woody and whilst still in reeling from the shock I did, through a set of naturally occurring and easily explainable to Mrs. W circumstances, find myself at a model railway shop! Strange that but also very convenient as I needed some Lais 21 pin DCC decoders and they happened to have them in stock. Pure coincidence of course Mrs. W!
There are no doubt reasons as to why there are various pin configurations for DCC decoders with 8 and 21 pin being the most common but there are also 6, 18, 20 and 22 pin varieties. Anyway, I knew that this Hornby Class 50, named Triumph, needed a 21 pin decoder and I have been after running it for some while so this is the first to receive a chip.
Getting into the insides was not too bad with two cables to unattached and four clips to pull apart. Once inside the complexity of the circuity is evident! Note, I even had the instructions to hand!
To the right of the chassis in the picture and on top of the main circuit board is the blanking plate. This allows the loco to run on a DC operated layout but need sto be removed to enable the DCC chip to be fitted.
Blanking plug removed and on the workbench whilst to its left the DCC awaits fitting.
Decoder fitted and as it allows the loco to run both under DCC and DC power a 9 volt battery was used to test that the chip was working before programming it.
Once programmed and now run in, 50042 Triumph takes on a few coaches on my layout.
I do like it - and the DCC chip fitting was a triumph too!
