ENGLISHENGLISH
The procedure of getting the Projector status
(1)Computer sends the command 20H+yyH to Projector.
(2)Projector sends the reply command 1xH+yyH+data bytes.
The procedure of setting the Projector status
(1)Computer sends the command 3xH+yyH+data bytes.
(2)Projector changes its status.
(3)Projector sends the reply command 1xH+yyH+data bytes which indicate status.
The procedure of default setting the Projector status
(1)Computer sends the command 40H+yyH
(2)Projector changes its status to default setting.
(3)Projector sends the reply command 1xH+yyH+data bytes which indicate default.
Connection to the control signal terminal (continued)
CautionIf projector replies 4Dh, (before command code, etc.) computer ignores 4Dh
Caution
The example of command error
When the projector cannot accept command from PC, error code 00H+yyH is sent back. 
(in a case when command code 2xH, 3xH or 4xH+yyH+data is sent from PC to projector)
The example of data error
When the projector cannot accept command from PC, error code with data 00H+yyH+data is sent back as
it is. (in a case when command code 2xH, 3xH or 4xH+yyH+data is sent from PC to projector)
When data is longer than required data code length, projector ignores excess data code.
When data is shorter than required data code length, projector sends back error code shown above.
The example of framing error
After setting to 1200bps 7N1, projector sends error code 70H+70H up to 10 times at intervals of 1 second
until any answer is received. When projector receives framing error code (70H+70H),
12H+03H+03H+10H is sent with 1200 bps 7N1.
The interval of command bytes and data bytes
After command code 2xH, 3xH or 4xH is sent from PC, if command or data is not sent within 500ms,
projector sends back error command 70H+70H. If no answer is sent within 1 second from that time,
framing error is assumed.
Caution·The interval of command bytes and data bytes must be over 1mS and under 500mS.  If it is
under 1mS, it may be treated as a framing error.
·After projector has sent back answer code, when next command is to be sent from PC, allow
for an interval of 40ms or more between answer code and other code. ·(3) data bytes is not always same as (1) data bytes. If projector cannot realize the status of (1)
data bytes, projector sets the proper status and replies this new setting data bytes or projector
replies the error reply 0xH+yyH+data bytes same as (1).
·When only power control (POWER COMMAND) is performed, it takes about 2~80 seconds
between sending set code and receiving answering code.
