the example for RGB LED setting is: "Port ID, Startup and Completion Information , 0x51, 0x01, 0x30, 0x47, 0x55" (which seems to make sense), but below at "RGB Commands encoded as WriteDirectModeData" the sequence is "0x51, 0x00, 0x51, 0x01, R, G, B" which seems to have invalid copy+paste prefix "0x51, 0x00" from the previous example (only "0x51, 0x01, R, G, B" would be more plausible).
