CMD1 is used to set the outputs (brightness and fade).  The format of the command is [1,Select_Bits, Brightness, Fade, 204] (5 bytes, no brackes)

CMD10 is used to Set TB1 if set to output mode:  The format of the command is: [10, Select_Bits, on/off value,204] 4 bytes, no brackets is sent from BrightAuthor.
On/Off value: 0 = 0ff, 1 to 255 = On.

CMD30 is used to Set TB1 Mode: The format is [30, mode, 204]

TB1_Mode = 0:

TB1 Mode = 1: Inputs (buttons) are reported to the BrightSign

TB1 Mode = 2: Inputs (buttons) activate scenes and closure must be maintained.  When the button is released, the scene is terminated

TB1 Mode = 3: Inputs (buttons) activate scens and closure can be momentary.

Definitions:

Select Bits (valid range 1-7): The 8 bits of a data byte.  Bits 0,1,2 should be set to affect drives 1,2 & 3 respectively.  Only the a data bit set to 1 will affect the drives.  I.E. if select bits = 4 (binary 00000100) then only drive 3 with be affected.

• Select Bits = 0 (non-operation), fast flashing of the 1Hz LED occurs.
• Select Bits = 1 (binary 00000001), controlling drive 1
• Select Bits = 2 (binary 00000010), controlling drive 2
• Select Bits = 3 (binary 00000011), controlling drive 1 & 2
• Select Bits = 4 (binary 00000100), controlling drive 3
• Select Bits = 5 (binary 00000101), controlling drive 3 and drive 1
• Select Bits = 6 (binary 00000110), controlling drive 3 and drive 2
• Select Bits = 7 (binary 00000111), controlling all 3 drives (1,2,& 3)

Brightness (range 0-255):  0 = OFF, 255 = Full on.  128 = 50% brightness)

Fade (range 0-255):  0 = instant, 255 = 255 milliseconds per step of change.  I.E. if going from 0 to 255 brightness, it takes 255 * 255 (brightness * fade) = 65536 millisconds to complete the change.  This is about 65 seconds!

Verify Byte (204):  This scheme of a verify byte ensures that with improper bytes, that the 'string of bytes'

Examples: (preceding 0's are not needed for BrightAuthor).  This format matches the 'Eltima Advanced Serial Port' software that I use for testing/controlling the RGB drives.  I highly recommend using this software while developing the scene commands!  If you use this same software and need assistance, I can provide some help to get you started.

01,01,255,20,204:  Command 1, drive 1, maximum brightness, fade = 20, verify byte

01,03,00,20,204: Command1, drives 1 & 2, no brightness, fade = 20, verify byte

01,07,255,0,204: Command 1, all 3 drives, maximum brightness, fade = 0 (instant change), verfy byte
