RS-422 Commands

I know this might sound basic to some, but what do the Record, Stop Play commands actually look like in an 8 bit stream, e,g. Rec= '01100203', Play = '01001000'......

I'm not sure I understand the way it's depicted in the developer guide.

Okay, maybe i didn't explain myself,

Byte 1 looks as though it's bin(00000010) for the record command and bin(00100000) for the stop command.

Do I need to send bytes 0-9, 0 and 2-9 being null values with byte 1 as the command, or can I just send byte 0 as null and byte 1 as the command?
