These sizes are ± 1 inch.  This is due to variations in the manufacture of the lens.  If you are close to one of the
endpoints you should verify with your unit that the image is the proper size at the proper distance.

c) Example of computer signal
Note  2: Some input sources may not be displayed properly because they are not compatible with the projector.Note  1: MAC adapter is necessary to set the resolution mode.
Projector is compatible with 13 inch mode and 16 inch mode.
Set all dip switches OFF except those indicated in the chart.
For example:
MAC 13 mode = switch 1, 5 and 6 are ON
MAC 16 mode = switch 2, 5 and 6 are ON
(Example of 16 inch mode)

Ask Code:
User:
20 XX
XX is the attribute you are checking.
Projector:
1Y XX Y bytes of data
This is a reply code. The Y is the number of extra bytes that come after the command.
The XX is the same as in the Ask code.
Set Code:
User:
3Y XX Y bytes of data
XX is the attribute you are checking. The Y is the number of bytes for the data.
Projector:
1Y XX  Y bytes of data
This is a reply code.  The Y is the number of extra bytes that come after the command.
The XX is the same as in the Set code.
Default Code:
User:
40 XX
XX is the attribute you are checking.
Projector:
1Y XX  Y bytes of data
This is a reply code.  The Y is the number of extra bytes that come after the command.
The XX is the same as in the Ask code.
Errors:
For an error, the projector will reply with the same code that was sent but with a 0 in the first nibble.
