Programming LGB switches with PIKO Smart Controller

1) I am having difficulty programming LGB switch decoders ( #55524) with the PIKO Smart Controller. Does anyone have some hints?
Thanks.
 
Are you setting CV2 to 77 first before you change the address CV1? Do you have a motor attached. And are you using programming track?
 
No. Might I have corrupted the default address? Is there a way to reset the default address?
According to the instruction manual the CV settings should be :
CV1 factory setting 1
CV 2 programming protection 77
CV 7 version
CV 8 manufacturer identification/reset
CV 9 address range, range 0-7, factory setting 0

The switch is not recognized if in the programming mode (on the programming track) and I attempt to “read”
Thanks for your thoughts on this.
 
Corroded through contacts, perhaps?

Is there not a link you have to fit on the LGB model, in order to program it? - It has not been mentioned, and I might have dreamed it?? :think::snooze:

Have you only got the one? - Could you compare with a different one, to prove you are doing things correctly?

Hi Phil,

On the LGB55025 you have to bridge the terminal marked ”PROG” on the Switch Decoder with a piece of wire or a safety clip. However Duncan is using the single channel decoder.

Hope this helps.

The standard way to reset a decoder is to to write 8 to CV8. No harm in trying that.
 
How about reading the manual, then reading the CV and noting it's value, then changing it?

Makes going back to what it was so much easier, than just changing values, no matter how well-intentioned?
Just a thought? :think:
 
Thanks.
I can "read" the following addresses from the decoder (which is attached to a switch machine).
CV 1=77
CV 2 =0
CV 7=18
CV 8 = 131
CV 9 = 0
CV 60 = 16
The device will not allow reprogramming. I get a recurring message when attempting to "write": "Programming error".

So, presently the address is set to '77'. - Can you operate the point if you select this address?

Have you read this section from the manual?:

Operation
This decoder has protection against accidental programming. When locomotives are being programmed, the turnout decoder may be connected to the programming process. Generally, CV 2 must be programmed with the value 77 before each programming procedure. After that, one CV can be changed exactly. CV 2 must be programed with the value 77 again in each instance before doing additional programming.

SO
Must set CV 2 = 77
Then set any other CV.
If you wish to set another CV..
Repeat set CV 2 =77
Then alter next CV.

Sorry if you are doing this.
PhilP.
 
Good info @John S thanks for updating us all.
D Duncan1 any progress with this? You said in an earlier post that the address CV1 was value 77. That's an unusual address to choose, so it could be that you or a previous owner accidentally wrote 77 to CV1 instead of CV2 as that is the code to temporarily unlock the decoder. But regardless of that does the decoder respond to address 77 when it is connected normally to DCC, not on programming track?
