Reference DAC Module - Discrete R-2R Sign Magnitude 24 bit 384 KHz

Are you using the ISO RXD and ISO TXD pins on J3 header for this? These are for TTL level, the manual really needs to explain this better.

Someone also mentioning a problem using that blue interface with dam1021 here, isolated input expects 3.3V levels, could it be outputting 5V levels?

Just tested with J3 connector.

Now I get the correct response but there is no way to start the uManager.
