Data
The RS232 interface and the ccTalk interface use the same UART, and therefore can
not be used at the same time. A jumper on a 3 pin header on the Sounder board must
be set to “CC” or “RS“ before using either interface. If you are using the RS232 to
program the board, to switch to ccTalk you must unplug the programming cable,
move the jumper from “RS” to “CC”, and power cycle (turn off, then on) the board.
The ccTalk slave address is programmed into the Sounder board with Sounder Link
software.
The Sounder board is controlled with 1 byte commands which are sent as data using
ccTalk header 20. These 1 byte commands are identical to those used by protocol 7.
Sounder responds to the report commands with a 1 byte data packet. It responds to
the play and stop other commands with a no data ACK data packet.
The Sounder board also implements ccTalk headers 4, 192, 244, 245, 246, and 254
per ccTalk specification version 4.5.
