This register only applies to Classic operation mode. 
 
In half duplex mode, packet length is always set to the default 257 bytes. 
 
In broadcast mode, when the packet length is set to any value other than the default 513 bytes 
the format of the data transmitted is as follows: 
 
Byte 0 = Start Code 
Byte 1 = Start Address MSB 
Byte 2 = Start Address LSB 
Byte 3 = DMX Data @ Start Address Slot 
Byte 3 + n = Remaining DMX Slot data up to packet length 

 

SHoW DMX Classic SHoW DMX receivers always transmit a full DMX frame. Embedding the start 
address in the data block allows a receiver to correctly place the block of data in the DMX 
frame. This maintains correct device addressing downstream of the DMX output. The unused 
DMX slots in the frame are set to 0x00.
