Notes for Communication

3.1.
The communication speed can be changed in menu. It starts to decode when the projector
receives the carriage return (0x0D).
3.2.
There are two types of command; the one is the Functional Execution Commands that execute
almost the same function as the keys on the projector body, and the other one is the Status Read
Commands that get basic status of the projector.
Example of the Functional Execution Command: "C05" [CR]
Example of the 0.Status Read Command: "CR0" [CR]
3.3.
It clears the information of buffer in the following cases.
3.3.1. - When the projector receives LF (0xoA) or EOF (0x1A).
3.3.2. - When it takes more than one second to receive a single command.
(Until receiving the carriage return after the reception of the first data.)
3.4.
Allow interval time as below after the reception of response, pipelining the control commands.
3.4.1. [VOLUME +/-] [ZOOM UP/DOWN] [FOCUS UP/DOWN]
[LENS SHIF UP/DOWN/LEFT/RIGHT] commands...100ms
3.4.2. The other commands...500ms
3.5.
Allow at least 500ms of interval time after the response, pipelining the status commands.
3.6.
Do not issue any command before receiving the response except the case that there is no
response for 5 seconds.
3.7.
It takes about 7 seconds for internal initialization after plugging in AC. During this time, it cannot
process command. Do not issue any commands.
3.8.
When the projector receives the commands for internal initialization or Iighting the lamps in
7seconds after starting POWER ON in the status of STANDBY, it does not carry out any command
except the Status Read commands, although it returns "Acceptable" response. The Status Read
commands are carried out after 500ms from when the "Acceptable" response is returned.
3.9.
About the action during Count Down and Cooling Down operation:
When the projector receives commands in the period of the Count Down operation after Power ON
or Cooling Down operation after Power OFF, it does not carry out any command but the Status
Read commands although it returns "Acceptable" response.
3.10.
About the action during switching inputs:
It takes 5 seconds to switch inputs after receiving the command. During the period, the projector
does not carry out any command except Status Read commands although it returns "Acceptable"
response. It carries out the Status Read commands in 500ms after "Acceptable" response is returns,
which is for receiving the commands to switch inputs.
3.11.
The text length of the returned value for the Status Read command in successful operation
depends on the command.
3.12.
The characters for commands must be in upper case (A - Z). Lower-case characters are not
available.
