What's in this update
Note: This firmware version requires RCP 7.64 Reworked Daylight Savings (DST) routines to allow the controller to automatically determine if current date falls within the DST time as per programmed parameters.
There is no longer any need to set or unset the DST Flag.
As such, this command has been removed.
Implemented automatic detection of ISD Type upon controller start up.
As such, the command to select it has been removed however the Interrogate command (*70072) has been retained Other corrected issues: If using RSSI in conjunction with RCV Macros, A/D readback would not work if called from DTMF running of Macro.
It now works correctly If using DTMF to program a Programming Command that starts with *, it was possible if that if the * wasn't decoded properly, the wrong Programmed parameter might be incorrectly programmed.
This is now corrected It was sometimes possible for a Linked To Port to be timed out by another Port, even if programmed not to allow that.
This is now fixed
