I am having difficulty activating my Dapol semaphores using the SC1/DP8 combination. I am using 16v AC and a Gaugemaster Prodigy Advance 2 DCC controller. The signal light is on, I can change the signal arm position using the appropriate button but not via the controller. Reading the accessory shows the following CV values:- CV1 = 001, CV9 = 000, CV29 = 128, CV38 = 15.
Using the Accessory button on the controller and pressing 1 and Enter shows "1 or 2" and "001" on the controller but pressing 1 or 2 has no effect at all. Any assistance you can provide would be most appreciated.

Hi John
I think the problem you are having is that with CV1=1 your Prodigy will only be able to control outputs 5-8 using addresses 1-4. CV1=2 should allow you to use all of them on addresses 1-8. Most command stations cannot access the lowest four addresses (when CV1=1). If you are having trouble just use the jumper address programming method described in the manual to set the address of the first output and make sure it is the first address in a group of four (1, 5, 9, 13, etc.)

Thanks for your response Paul. Q1. Could you clarify whether I should have the DP8 connected to SC1 when trying to set CV1 or should the SC1 be unwired apart from to the controller? Q2. What is the default address that the accessory decoder would be assigned if I try the jumper address programming method and should my controller be linked via Prog Track connections? Q3. Is there meant to be a link between the Address set up in CV1 for the accessory decoder and the first and following output addresses of the individual outputs? Apologies for queries but this is the first time I have tried to use an accessory decoder. Regards, John

A1 - It does not matter.
A2i - The default address (with DP8) is turnout addresses 1-8 (of which the prodigy can access only 5-8).
A2ii - The address assigned by the jumper method is the last address that you try and activate before you remove the jumper and power off.
A2iii - If using the jumper method use the track connection, for all other programming use the program track connection with the jumper removed. The jumper must be removed for normal operation.
Note that the address is defined by a combination of CV1, CV9 and CV29 - not just CV1.
A3 - You set the address of the first output and the rest will follow sequentially. This is the standard NMRA address method.

Thank you Paul, I hadn't realised that I should use the track connection for the jumper programming method. It worked first time once I tried it with the track connection. Thank you again for your assistance.
