}'3: The run time mask. This indicates what run times you would like to target with this message. 3 is 0000 0011 in binary, there for it will change run time 1 (b0) and run time 2 (b1).
0,0,0,0: This will set run time 1 to 0.
0x15, 0xCD, 0x5B, 0x07: This UINT32 value is made up of 4 bytes. 123456789 in 32bit binary is 00000111 01011011 11001101 00010101. This can be written as 0x07, 0x5B, 0xCD, 0x15 in hex (or 7, 91, 205, 21 in decimal). This is big endian, and the async payload structure is little endian. Therefore, it is written and is sent as 0x15, 0xCD, 0x5B, 0x07 or 21, 205, 91, 7. The message can be sent in either hex or decimal.
0,0,0,0: Since the run time mask for run time 3 is not set, this value can be set to anything and will have no effect.
