Parity:
Command Format:
CMD1, CMD2, Data bytes ...., Checksum byte
A Command is made up of two address bytes, CMD1 and CMD2, a variable number of Data bytes
(Data from 0 up to 15) and a Checksum byte. The Checksum byte is the modulo 256 sum of all
preceding bytes.
The most significant nibble of the CMD1 byte represents the command group. The least significant
nibble represents the number of Data bytes to follow the CMD2 byte.
Command Protocol:
CMD1, CMD2, Data bytes ...., Checksum byte
Response: ACK
Other than the sense command, the unit will respond to all commands affirmatively by sending a three
byte acknowledgement (ACK) if the Checksum is valid. If the Checksum is not valid, the DN-200 will
ignore the command. Most commands will be responded to within 8 msec. However, a PLAY
command from an idle state will result in response delay of up to 700 msec. During this busy time, all
commands will be ignored.
