In the most recent batch of SDC2160 controllers we have received the Analog1 input appears not to function but we have proven code and well tested the operation of this input in all previously received parts. It seems only consistent with a batch of parts received in July. Has something changed, is there new firmware with a bug or are these items faulty ?

Note that since version 2.1 of the hardware almost 2 years ago, ANA1 position on the 15-pin connector has been changed.

It was mapped with Digital input 5 (pin10).

It is now mapped with Digital input 1 (pin4)

If this is the reason for your problem, you can either recode your application so that you read your analog singnal on ANA5, rewire the signal to pin4, or use a unpublished configuration command to remap analog input 1 back to pin 10.

Hi. Thanks for the reply. Yes we have done some checking and as far as we can see we have all Hardware Version 2.1 (printed on the boards and stickers) but ANA1 is on Pin 10. New parts are all the same Version 2.1 but the ANA1 does appear to now be on Pin 4. Obviously the hardware version we see printed on the boards is not the actual hardware version or the configuration command has been factory set already, even though we didn't ask ?

We have may legacy system out in the field and need the unpublished command or an ability to read the actual hardware version.

You can determine the hardware version of the controller using the serial command ?UID. This will return a string of numbers but the first number is all that matters:

If the first number is 300, this will be our newest hardware revision (v2.0 or later). It is with hardware revision v2.0 that the new pinout mapping took place. Note that all of our SDC controllers since mid 2016 are hardware v2.0 or later.

If the first number is 100, this will be the old hardware revision (v1.5). This hardware revision has the old pinout mapping where Analog 1 is on pin 10.
