Hi,
Does anyone know if I can program old V1 R8247 hornby decoders with the new Yamorc upgrade from DR5000. I understand they can " learn" so have to be put on program track and done one at a time. Anyone got a step by step as new to this bit.
cheers

Should say they CAN'T learn....

Hi,

?

From the manual:

?

Programming Method The R8247 Point and Accessory Decoder (PAD) version 2 is an enhanced release over the original R8247 (released in 2006.) This new version supports programmable pulse duration and number of pulses per port. Also, support for Channel grouping has been added allowing multiple point control etc from a single address. Finally, there are now 3 address modes, further expanding the flexibility of the unit. The R8247 is configured with 4 addressable Channels. Each Channel has two ports. There are 3 physical connections per Channel. The 3 connections per Channel are labelled +, – and C. These are only used to differentiate the connections they do not represent polarities. Note that the actual pulsed or continuous voltage appearing at either of the + or – outputs is actually negative (12V) going relative the C (common) connection. These three connections make up the two Ports of the Channel. All C connections are connected together internally. There is a track signal input/power connection at one end of the unit. It is recommended that this is connected to the main power bus of the layout or accessory bus if separate. The connection is not Polarity sensitive. Programming is carried out via the “track input signal” connection (see above) DIRECT mode programming is recommended. i.e.. “Service Mode” via the programming output of your controller. If required Paged mode and Register Mode are supported. Note: Register mode is not recommended due to limitation of CV support. Programming via “OPERATE Mode” (On the Main) is also supported. This may be convenient in some instances. However, connecting directly to the Programming output of your Controller for programming (SERVICE MODE) is the recommended programming method. The unit has quite a complex set of features, so using the Programming connection on your controller may be advantageous as it should support READBACK of the CV values. Please refer to the full CV list for more details

Manual is to be found here:?

As far as I read the manual. The YD7001 is capable of programming this decoder.

Direct Link to the manual:??

All,
I have the V1 version which I suspect has a lot less functionlity of the V2 in the manual above. Being a total novice with this and not understanding the basic premise I am a bit stumped.
So I have connected a peco point to the R8247 and connected the R8247 to the programming track.
I have 3 options service , decoder? or accessory . POM which one?
Address? is it 9999 ?
Cv number ? Is the number I start at ?
Bit? not sure what this ?
Please help as I have worked through today sorting out the Yamorc? YD7001 from being a DR5000 and it works fine , train running all good. I even have a pre programmed R8247 numbered 1-4 and that works. I just dont know how to get the new ones to program.

Please can someone tell me what numbers to put in the boxes please or am I completely wrong.

When using the Programming Track ==> Service Mode is the only one. ( and the only onde that the R8247?supports )

Hi,
Tried and failed to use the service mode on the programming track. I have read the old manual and watched a? few old youtube videos and it says to put 513 in the CV box. What do I put in the address box? I want it to be 10th accessory decoder? as a block of 4. Whats the value mean and the little bit boxes below that?
Hope someone can help so I can the old decoders reprogrammed.

So,
?As it is showing no load I think i must connect this to the main track to program it as it hasn't got its own power supply. Showing NO LOAD or this something else?
I have to set up CV 513( Cv1) to read value of 10. Soleniods block of 4 and 10th point motor accessory.. then write this?
I have to set up CV 33 value 0 which sets it up for solenoid stanard set up.?

Slowly tryinng to work through this but what do I put in the address boxes each time? The decoder unit number 10?

Can I have some input from someone please. I will try this and see if it works in the morning as I can't afford to dispose of the 7 units I have to buy new .

All,
Please can someone help. I have tried everything . I have read about CV's and such for the last few days and I believe I am doing things correctly, The R8247 is version 1 and has 4 ports. These are the steps I am following on the screen shot previously shown. Set to service and the accessory decoder? is connected to the programming track.
CV33 to 0 as I want it to drive solenoids
CV513 change to value of 33 ( this is the block that of 33-36) that i want it to be.
All it comes up with is NO LOAD. Does the R8247 need its own power supply when being programmed?

Is it safe to connect the YD7001 to R8247 and the main?
Is the power too high for the programming track? 19V??
Should it connected to the main track?

I have tried to change it with JMRI single CV programmer and the YD7001 with No luck . I have tried? all kinds to combos with no luck. I am learning about the systems slowly but I am stuck as I believe I missing something simple out.
Just can't see it
Please help

Hi Gordon,
