'0' (30h): Reserved

Monitor ID: Specify the Monitor ID from which you want to get data. Ex.) If Monitor ID is '1', specify 'A'.

'0' (30h): Message sender is the controller.

'A' (41h): Message type is "Command".

'0'-'A' (30h, 41h): Message length is 10 bytes.

Message

STX (02h): Start of Message

'C'-'0'-'0'-'B' (43h, 30h, 30h, 42h): Asset read request command.

'0'-'0' (30h, 30h): Offset data from top of the Asset data. At first set 00h: Read data from the top of Asset data area.

'2'-'0' (32h, 30h): Read out data length is 32bytes.

Secondly set 20h: Read data from the 32bytes offset point in the Asset data area.
