The procedure of getting the Projector status.
(1) Computer sends the command Õ20HÕ + ÔyyHÕ to Projector.
(2) Projector reply the command Ô1xHÕ + ÔyyHÕ + data bytes.
The procedure of setting the Projector status
(1) Computer sends the command Ô3xHÕ + ÔyyHÕ + data bytes.
(2) Projector changes itÕs status.
(3) Projector reply the command Ô1xHÕ + ÔyyHÕ + data bytes which indicate status.
Caution(3) data bytes is not always same as (1) data bytes.
If projector cannot realize the status of (1) data bytes, projector set the proper status and reply
this new setting data bytes or projector reply the error reply Ô0xHÕ + ÔyyHÕ + data bytes same as
(1).
The procedure of default setting the Projector status
(1) Computer sends the command Õ40HÕ + ÔyyHÕ
(2) Projector changes itÕs status to default setting.
(3) Projector reply the command Ô1xHÕ + ÔyyHÕ + data bytes which indicate default.
CautionIf projector replys Ô4DhÕ, (before command code, etc.) computer ignores Ô4DhÕ
The example of command error
(1) Computer sends the command Ô2xHÕ, Ô3xHÕ or Ô4xHÕ + ÔyyHÕ + data bytes.
(2) Projector doesnÕt understand (1) code.
(3) Projector reply the command Ô00HÕ + ÔyyHÕ
The example of data error
(1) Computer sends the command Ô2xHÕ, Ô3xHÕ or Ô4xHÕ + ÔyyHÕ + data bytes.
(2) Projector doesnÕt understand (1) data bytes.
(3) Projector reply the command Ô0xHÕ + ÔyyHÕ + data bytes same as (1)
The example of framing error
(1) Projector detect framing error.
(2) Projector changes to 1200bps 7N1 if it doesnÕt 1200bps 7N1.
(3) Projector replys Õ70HÕ + Õ70HÕ 10 times, every 1 second.
(4) When projector receives Õ70HÕ + Õ70HÕ, it replys Õ12HÕ + Õ03HÕ + Õ01HÕ + Õ00HÕ.
The interval of command bytes and data bytes
(1) The interval of bytes exceeds 500mS.
(2) Projector replys Õ70HÕ + Õ70HÕ.
(3) Projector wait 1 second for the computerÕs any command.
(4) If there is no command from the computer, projector treat as framing error.
Caution¥ The interval of command bytes and data bytes must be over 1mS and under 500mS.  If it is
under 1mS, it may be treat as framing error.
¥ The interval of Reply code and other codes must be over 40mS.
