So, Update on this, I went ahead and fully programmed the unit as suggested, fine, it can read the addresses for the points and switch them correctly, so I'm happy with that unit. The second unit I needed to program, plugged in straight away and flashed as stated in the DCC Next manual, eventually got this all programmed as well. All in all, everything is working as it should, I'm just slightly confused regarding one unit flashing and the other, doesn't matter however, they are all programmed and working. Thanks for all your help.

Hi, I just had a chance to try this just there, unfortunately I'm still not getting any flashing lights etc when i send the command 1, or even programming an address in to the unit and trying that. I feel I'm missing something here. Thanks

I haven't uploaded the sketch on to the unit yet, doesn't state to do that in the instructions, but that makes sense to do that. I have set up one of these units a long time ago, trying to remember how I did it. I'll give this a try when I get home.

Hi All, Just wondering if anyone has any experience of setting up a DCC Next from ArCoMoRa with a DR5000? I have followed the manual of the DCC Next to the point that it request me to send address 1 to the DCC Next. There is no flashing light response from the unit. Has any one had something like this before, and if so, how did you get around it? Thanks

Ok, so considered alright to remove and bridge then, thanks

Good Evening, I'm looking for some help identifying a component inside a loco. I recently got an n gauge loco at the recent Glasgow show (Fleischmann 7175, DB 050), and opening it up in preparation for a DCC conversion, i've come across what appears to be a coil of wire with an iron bar through the middle of it. It also looks like it has melted some of the surrounding plastic. What is this component, is it necessary/safe? and is there a modern, safer equivalent. Pictures Attached Thanks

ah, i didnt realize the one at whitrope had been upgraded/changed

old style whitrope box?

Ill have a look via teh NBRSG then, thanks was there a significant diffrence between those on the waverley and the rest of the NBR system? i know the west highland boxes were diffrent, but didnt think there was much diffrence over the WR?

I havent seen any thing listed in either their sales page or archive. might possibly be something in the journals, but i would need to get them to check. just asking incase someone knew right away

Hello all, Bit of a thread resurection i know, but the question is relevant. Are there any known elevation plans of NBR boxes? Looking particularly for a small to medium box. Thanks

yeah , do mean the 0v output of the 12vDC outout, im not really electricaly minded, so noting it down like that is easier for me if not correct.

ok, thanks for the advice. the mardec has auxiliary pins for these functions, and claims to be able to do these things, so should be fine.

hmm, thats unfortunate. ive got an 8 way board coming on monday, so how should i wire that one in? Vcc to 12vDC+ GND to 12vDC- or should they be connected to the 5vDC +/- terminals on the Mardec? or 12vDC+ and mardec - ? thanks for the offer but ill just get another from Ebay, itll probably work out quicker

having just checked, there is deffinetly a circuit between both pins and the Vcc on the row of 6 pins i cant see anything on either side of the board to suggest a connection problem.

yeah, jumper os on between VCC/ JD-VCC yes, each LED lights when i connect the signal wire, but there is no click, nor doe the circuit between com and NC break. this is the same on all 4

HI no, no noise what so ever when the relay in energized. there is a circuit between middle and left (com and NC) which is consistent, even on connecting the power to the IN pin. the same happens on the other three relays as well, COM to NC stays in contact and doesnt change when power is applied. the solder contact of the board look fine

right, so as suggested, the board is sitting with only gnd connected to 12vDC- and VCC connected to 12vDC+ (jumper is on between JDvcc and vcc) using a wire connected to the same 12vDC- source i touch the IN pins and get the LED coming on. measuring for contact between the NC and common they are in constant contact. would this suggest that somehting has broken?

can anyone provide a labled wiring diagram for what should be going where? ive tried the last few suggestions but as of yet ive had no joy

https://www.arcomora.com/mardec/ thanks for the responses, this is the site for the mardecs, essentially a cheap accessory decoder. ive just had a try with the 12v negative supply on to one of the IN pins, no joy, the LED lights up when i touch the wire to the contact, but no switching of the relay

yes, the red is 12v+ and the blue 12v- i should point out that the imput from the mardec is ~4-6vDC,. seems to be fairly constant

attached is a picture of the relay unit. the wires in to the screw terminals are the NC common and No terminals with the dcc/ track voltage bottom corner has (from top to bottom) 12vDC gnd, input1-4, 12vDC VCC then 12vDC JDVCC

I think this is the right spot for this, but if not let me know. So, im having some porblems with wiring in some relays. i have some DIY ABC modules wired in to the ends of the loops on my fiddle yard. the whole idea being the routes are automaticly set via JMRI, the points switch automaticly and the blocked lines have ABC activated towards the end of the loop to stop any incoming trains. to do this the ABC modules are switched on and off via Dcc imputs from an ArCoMoRa mardec. the imput from the mardec switches is supposed to switch the relay between ABC and ABC bypass, however i get no switching on the imput from the Mardec. there is a minor dimming of the onboard LED (Relay) with the signal, , but being no electronics expert, im not sure if ive wired this correctly, or not, any help appreciated

thanks for the help

So, problem found and sorted. turns out the octocouple chip on the mardec was inserted the wrong way, silly me
