Solution 1:[1]

According with DALI communication protocol, your frame should be like this:

frame[0] = 0x83;
frame[1] = 0x00;
frame[2] = ....; // DALI device id
frame[3] = ....; // 10 + scene number
frame[4] = frame[1] ^ frame[2] ^ frame[3] ^ frame[4]; // Checksum

It is just one command, 5 Bytes total.
