TC4820 features an optional secondary thermistor input for sensing alarm conditions. Interest has been expressed in making use of this feature.

Appendix B of the manual hopefully contains the information required to do this. A quick scan of section "IV. Serial Commands" makes me think we might just be able use request_decimal("040000") (cf. request_decimal("010000") for reading the control thermistor temperature), if all we want to do is read the temperature from this secondary thermistor.

  • The retrieved value should be written to the log file, along with that of the control thermistor.
  • The retrieved value could be shown on the GUI, but where to put this is not obvious, as it won't be related to the hot or cold blackbodies.

I'm not convinced we need this and we do have to prioritise our tasks. @jonemurray?

Nope, we can look at this. We might need to chat about it at some point though, so I'll leave it as "needs info"
