Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.
Aspect ratio 16:10
minimum L (m) = (diagonal screen size in inches) × 0.03338
maximum L (m) = (diagonal screen size in inches) × 0.03660
Aspect ratio 16:9
minimum L (m) = (diagonal screen size in inches) × 0.03429
maximum L (m) = (diagonal screen size in inches) × 0.03764
NOTE: 
Distances calculated with the above equations will include a slight error.
Installable angle
Install the projector at an angle within the range shown below.

The projector may be installed at a vertical
angle of 10°. 
The projector may be installed at a horizontal
angle of 20°.

* STX and ETX are character chords. STX is 02 and ETX is 03 when expressed\
 in hexadecimal.
Basic format
Transmission from the computer begins with STX, then the ID, command, parameter, and ETX are sent
in this order. Add parameters according to the details of control.
CAUTION
 It may not be possible to send or receive commands for about 10 to 60 seconds when the lamp is first turned on. If this
occurs, wait for 60 seconds, then try sending or receiving again.
 When sending multiple commands, be sure to wait for at least 0.5 second after receiving a response from the projector before sending the next command.
 Additional time is sometimes required for response due to processing inside the projector. Set the time-out period for com-
mand response to 10 seconds or more.

* Do not send PON, POF or OSH commands continuously in a short period of t\
ime. Doing so may burst the lamp or shorten the lamp r eplacement
cycle.
* When a command that cannot be executed during standby mode is sent, the \
projector will send an ER401 command in reply.
