After wiring some of the KFlop I/O to a relay board, I find the I/O is initially unstable when power is connected to KFlop. What is interesting is that one to two outputs are toggled but others are not.
Is there a way to prevent the I/O from toggling at random during boot? The relays are driving motors and coolant so this could create a problem unless another relay is used to manually energise the motors after boot.

Hi Eon,
Not sure exactly what you are referring to but Bits 16-20 and 23 on JP4 are momentarily driven to auto detect the presence of a SnapAmp and Bits 12,13, and 15 on JP7 are momentarily driven to auto detect the presence of a Kanalog. That might be what you are seeing. If that causes a problem then as you describe another relay or I/O might be needed to keep things disabled until after the boot has completed.

Thanks Tom
Yes, this is what is happening. It is a pity this cannot be disabled somewhere – the checking is only needed when configuring the system initially and then never again as the configuration for a specific machine is unlikely to change and if so, needs to be configured again.

Hi Eon,
Well that sort of defeats the purpose of auto detection but I could see how that could be a problem. Here is a Version 4.33o that allows disabling the autodetection.
http://dynomotion/Software/KMotion433o.exe
After upgrading run the attached program to set the disable autodetection flags:
Then Flash User Data. The Autodetection will be disabled on the next boot. You will need to remember to do this whenever a new Firmware is loaded, boards swapped, or configuration changes.

Hi Tom
For some reason I am not able to download the version 433o but I can download the other versions. What could be the reason?
