The response of the unit to a correct Operation Code consists of the byte 1E followed by a copy of the
packet that has been sent to the unit, where, however:
- byte number 11 is set at 01,
- CRC (bytes number 6 and 7) has been altered accordingly.

Get Codes
Get Commands may be used to get the current value of projector parameters.
The response to a correct Get Command consists of 33 byte packet, where Byte Number 11 contains the
Validation Code (01) and bytes Number 17 and Number 18 the requested value (the least-significant byte of
the value being sent first). Of course CRC (bytes number 6 and 7) has been altered accordingly.
