Observations

Setup Message

0x69 
0x34 

Seem to be at the beginning of every setup(?) message from the driver.

0x69 
0xb4

Seem to be at the beginning of every setup(?) response message.

Laser/Axis Power Message

< 0x75 (u)
< <axis/laser byte>
< 0x34 (4)
< <value byte>
< <value byte>

The last 4 bits of the Axis/Laser are always the same in two consecutive messages.

(0x84, 0xf4) (0x02, 0x72)

The whole byte is incremented by 0x70.

Setting Laser Power Min and Max to 100.00 in the commerical driver software yields 0xcece in the value bytes.
