Device ID (read-only) — RCL "DevID" returns the type of DM42 you’re using. There are currently two hardware models only identified by value 0 (zero) is returned by the DM42 units that we have. Other types of unit that may be produced in future will have different DevID values. - Page 7 Zone Main area (stack/graphics) Goose Annunciators In order to prevent any part of the LCD from refreshing and thus maximize performance, store the value 0 (zero) in "RefLCD". Storing 1 in the variable means that the main area will be updated with 200ms timeout (stack or the graphics display if that is what is active).
