What's in this update
Feature and Operational Changes Major Revision Numbering Change To Match new RCP Release Aux Audio Routing command eliminated (*2100xxx).
Aux Audio now uses Port Steering Functions (166- 169) for Port Routing.
This allows for on-the-fly changes, making operation much more flexible.
Added support for future RTC Daughterboard Macro Priority used to only work on Ports set to repeat.
They now will work on any Port regardless of repeat or non-repeat.
Removed software defined serial buffers (which frees up a ton of RAM space for the DTMF buffers) as the serial port hardware UART has its own buffers.
Software ones are superfluous).
Changed the pound (#) to an asterisk (*) that is used in programmed Meters, Meter Alarms and Courtesy Tones.
This allows programming of these features from the phone line.
When a Timeout condition is cleared, the controller will now speak "Repeater Timeout Cancel" so the user knows exactly what happened. (this message is sent out ONLY Ports defined as repeating) Removed requirement for separate programming command ("Half Duplex ID") in order to allow non-repeating Ports to ID.
Now, simply set that Port's Initial ID Timer to 0 to disable.
Otherwise that Port will ID.
Fixed bug where CTCSS Encode didn't work properly during startup "Ready" announcement Added capability to set Clock to seconds.
If only use hh: mm when setting Clock, seconds are zeroed to top of the minute.
If use hh: mm: ss then seconds set to value.
New feature added to allow interrogation of remote base frequency, offset and mode.
To interrogate, simply enter the Remote Base Prefix with no argument.
IE Remote Base Prefix = A7.
So enter A7 and unkey Fixed Tail Message Timers which were broken in an earlier version Note: This firmware version requires RCP 5.28
