banburysaint Posted June 29, 2014 Share Posted June 29, 2014 I know with solenoid point motors on DC you can add a CDU to add extra umph to the throw. This is a really basic question but can you have a CDU on a digital controlled point motor? If so where on the circuit does the connection go? Many thanks Link to post Share on other sites More sharing options...
Brian Posted June 29, 2014 Share Posted June 29, 2014 Not normally no. Some accessory point decoders have built in CDUs anyway. Not all though. So check if a CDU is essential. These have CDU built in.... Team Digital SMD82, Hornby R8247 (these have one CDU shared between all outputs), DCC Concepts ADS2 or the ADS8 which have separate CDU per output. There are others of course. Link to post Share on other sites More sharing options...
banburysaint Posted June 29, 2014 Author Share Posted June 29, 2014 Brian, thank you for the post I am using a E-Z Commad Dynamis Point decoder 36-561 (which is an ESU switch pilot). I dont believe it has a CDU in built. I am only trying to fire one point at one time. In the instructions it states you can modify the CVs to cope with a peco motor (i am using the lower power versions). I have attempted to this however as i use a Digitrax 150 unit i cannot read back the CVs. Link to post Share on other sites More sharing options...
Brian Posted June 29, 2014 Share Posted June 29, 2014 Page 16 of the ESU Switchpilot manual states..... In order to be able to read out any data you must connect a load to output 1 Out A that draws more than 60 mA, for instance a light bulb or a 180 Ohm / 1 Watt resistor.

banburysaint Posted June 30, 2014 Author Share Posted June 30, 2014 Thanks for looking deep into the ESU manual. I have managed to change the CVs (i checked by tweaking one to give the pulse for the duration of the button press, my controller can only write CVs). I also changed the power supply from the DCc controller to a gaugemaster controller auxiliary output which i use for my turn table. And success my point now throws with a satisfactory thump! Only 15 more to go! cheers Peter Link to post Share on other sites More sharing options...
RMweb Gold Colin_McLeod Posted June 30, 2014 RMweb Gold Share Posted June 30, 2014 YES if you use ZTC. They supply a very neat CDU to attach to their accessory decoder. A pair of H&M point motors throw with a nice hefty "thump" Link to post Share on other sites More sharing options...
