Control command codes
The control command packets have a data length of 7~11
bytes. ASCII codes from 0x00 to 0x7f are used to receive
serial data. At the transmission end, take steps to convert
the ASCII codes into HEX data to set the data in the data
packets. CR (0x0d) is added as the data packet delimiter.
Example: Control command code for number 5 (ASCII code
@02305CR)
@02305CR
0x40 0x30 0x32 0x33 0x30 0x35 0x0d
When transmitting commands consecutively, put more than
100ms blank between commands.
Status Request and Status Information codes
The status data packets have a data length of 7~12 bytes.
ASCII codes from 0x00 to 0x7f are used to transmit serial
data. For this reason, the ASCII codes are converted into
HEX data before the data is set in the data packets and
transmitted. CR (0x0d) is added as the data packet
delimiter.
Example: Status Information code "Door open"
(ASCII code @0DS01CR)
@0 DS 0 1CR
0x40 0x30 0x44 0x53 0x30 0x31 0x0d
Hand shake flow charts for control commands
Host sends a command that causes a change in PMD560
status.
Host sends a command that causes no change in PMD560
status. For example, Host requests Play during Playback.
Status Request Commands from the host are received by
the PMD560, then the status information code is transmitted
to the host.
A change in the state of the PMD560 automatically transmits
a status information code to the host.
