More Device Tables

The SAMINFO is the table of interest.
It seems the rows 3B02 and 3b03 are coughing up zeros for the newer "touch" models and most of the good data for the older models.
Can you expore the contents of other rows on this table?
Change your code to request rows 3b04, 3b05

If that doesn't yeild information, try the tables between LINESET and SAMINFO, like 0x07, 0x08, 0x09, 0x0A... etc.

All the rows for SAMINFO were empty (zeros). I scanned (if I recall correctly) all the way up from 0x01 through 0xaf and did not find any additional tables.

Ok, nice work. Now we have a bigger mystery...in what table is the thermostat data located for "touch" thermostats....
I think we need to scan them all or find someone with a SYSTXCCRCT01 SAM set up where we can run wireshark or something.

I noticed there are dealers selling SAM (RJ45) version. I supposed its POSSIBLE the touch thermostat doesn't have the data. My dealer told me Carrier has discontinued the SAM and will be updating software for the touch thermostats to provide access in some way.

I suppose its possible the Touch thermostat just doesn't cough up the needed data.

SAMINFO will be populated if a SAM is present, but one has to go through the entire setup process(not just the bootup discovery process) for it to be populated. That said, the stat does cough up the needed data in higher tables (the 0x40 SCHEDULE table in particular) which Infinitude will scan and parse if the SCAN_TABLES environment variable is set.
