hey everyone
I need help installing my d14srp NCE decoder in my Kato Ho scale Sd90mac, I am looking for pics or anything, I don’t know how the plug n play decoder goes in there because there is something on the board already soldered in from the manufactur?
Any help?
Thanks
There should be a little plug already in the socket that joins certain pins to permit operation without the decoder. You need to unplug this little board from the main board and then the decoder should plug right in.

any pictures or detailed instructions would be nice?
he just gave you the ‘detailed’ instructions…its that easy…remove little jumper board, plug in decoder…done.

I listed a web site that shows the board and some explanation. There are two articles on the KAto SD90/43 mac and talks about a problem that existed on some of them.
There are many items on Tony’s, Check it out.
Looks liek Kato takes the cheap way out and doesn;t even use a shorting plug, just a couple of ‘jumpers’ across the pins. Remove those and the decoder should plug in. The issue described at Tony’s doesn;t really affect plugging a decoder in, however if that strap is too long and does short out it will destroy the decoder. So while the shell is off - take a look and fix per the web site.

well that still doesn’t help me.
I might jsut tell you what I have a second run SD90mac CEFX
using a NCE d14srp decoder, with 8 pin medium
on the diagram provided it shows numbers on the board that correspond to the decoder, now where the decoder is supposer to go lies something that has 6 pins sticking up and soldered underneath, any suggestions, please?
thanks everyone
Is this engine new, or “previously owned”? Maybe someone modified it before you got it??
brand new bought from my wholesaler
Its very simple to install. Just pull the two plugs out of the circuit board on the locomotive and plug in your decoder. The plugs are two metal jumper plugs, maybe your looking to hard for them.
Those little pins sticking up aren’t soldered on. The pin socket below them is. There should be two empty holse around those 6 pins. Pull the pins out, might need a needlenose pliers to drip on them to be able to pull, I know my fingers are large enough that I would definitely have trouble without pliers. Then you should have 8 holes, per the picture linked from Tony’s site, Kato numbers them 1-8. The decoder will plug in here. Don’t worry if you put it in backwards - nothing bad will happen, the loco will merely run backwards when you set the throttle to forward. The design of the wires inthe 8-pin connection are such that you won’t damage the loco or decoder if you accidently plug it in backwards.

thanks, now to find some instructions to program with a DT400 now, got so use to my dt100, anyone know any good sites?
DT 400 is simple…honest! Place the loco on a section of programming track and hook up your controller box leads to it. With power to the track indicated as “on”, the loco should make noises, but not be able to move IF you are truly using the method for a dedicated programming track. In such a case, there isn’t enough power to the rails to move the loco, only to talk to the decoder and to get it to cooperate…reset as you desire.
So, if you are all set, press the program button, and the first screen should be “Page Mode”, which is what you want.
Rotate the left encoder and you will get “Ad 2-???”, or something similar, and if your intended address is less than 127, you are set to enter whatever it is using either the right encoder or the number pad. Press “Enter”, and in my system’s case (SEB with the DB 150) you’ll get a beep, followed by silence. The track power will have been turned off by the controller. Exit programming mode (press “Exit”), and restore track power. Your loco, if it is QSI-equipped, will probably sit dead quiet, even though power is on!!! Yeow! What did I do?! Fear not…just dial in the new address on one of the encoders, and click the encoder. Your loco should begin to respond as you wish.
To change other CV’s, program, click through to Ops Mode, dial the desired CV on the left encoder, dial in the value you want on the right, Enter, Exit, and Bob’s yer uncle.
4 digit addresses, a little more help would be good?
any good websites?
For 4 digits, when you enter programming (Page mode) and click the left encoder, it will do as I stated above. Click the right encoder, and the display changes to Ad 4==???
Now you have two choices for entering the address, either the left and right encoders, in that order, to get the thousands, hundreds, tens, and ones, or simply pu***he number keys in the right order. Press enter, and you will get the beep and silence. The instructions say there will be one more step.
The display is asking you if you want to change CV 29? The answer is yes, because the decoder won’t accept the new extended address without CV 29 being changed in value to 38. So, the display is showing “Ad4on?=y”. At this point, you will press the “Y+” key, and not a single thing will happen…at least in my experience.
So, you exit programming, ensure that power is restored to the track, you should get no response from the loco…if QSI, remember… and you must now use one of the decoders to dial in the new address and click to activate. The loco should respond very soon.
If nothing happens, what I have done is to re-enter programming but scroll down to “Ops Mode”, dial in CV 29 on the left encoder, dial in 38 on the right, press enter, exit, dial in the new address, click, and you should get the response.
Good luck!
