@neal@video.typica.us As far as I know, Diedrich no longer offers the DATAQ hardware as a logging option. That was always a weird design choice made to keep the cost of the option down and was especially painful for temperature measurements where the combination of low resolution ADC, mis-matched range for the signal conditioner feeding that compared with what values could be reasonably expected, and poor channel isolation made it difficult to get this working as well as it does in Typica.
