CDC Protocols – Mictronics. This page contains informations, links and descriptions about various CDchanger protocols. Choose your brand: Blaupunkt ( DMS ?? Then the data transfer starts, a 1 is encoded as a high- low sequence witha duration of ap. The data is now transfered in bytes with MSB first, the 8th bit is an oddparity bit. At the end of the 3rd and all following Bytes there is an additionalbit inserted after the parity where the receiver acknowledges the transfer. This is done by holding the data lines in a high state after the initiatorsets them low. If this ack is missing the transfer is stopped. The timings may vary because the real data is encoded in the pulse to spacelength relation. The first 3. Bytes seem to be some kind of device address. The changer I usedtransfered a 0x. The next 4 bits were always high. After that a size byte and then size byteswere transfered. The last byte in the transfer is a checksum generated addingthe values of all data beginning with the 4bit sequence ( = 0x. F ). In the following part I only will write the raw data excluding size and cheksumfield. Each command transfered was first answered by some acknowledge packet consistingof a single 0x. A1.(which looks like: 0x. F 0x. 02 0x. A1 0x. B2 - > 0x. B0 is the checksum). The following packet sended by the changer contained the time disc and trackinformation. Byte. 01. 23. 45.

There is one dataline, a clock line and a sync line the changer uses to send data to the radio. The radio to changer communication is done by some signals known from standard.
