(RS-232C) Specifications and Command Settings
PC control
A computer can be used to control the projector by connecting an RS-232C serial control cable (cross type, sold
separately) to the projector. (See page
23 for connection.)
Communication conditions
Set the serial port settings of the computer to match that of the table.
Signal format: Conforms to RS-232C standard.
Parity bit: None
Baud rate: 9,600 bps Stop bit: 1 bit
Data length: 8 bits Flow control: None
Basic format
Commands from the computer are sent in the following order: command, parameter, and return code. After the projec-
tor processes the command from the computer, it sends a response code to the computer.
Info
•
When more than one code is being sent, send each command only after the response code for the previous command from
the projector is verified.
•
To conserve power in STANDBY MODE, the CPU in this model will enter Deep Sleep mode approximately 10 seconds after
the last command is received. In the case of transmitting commands during Deep Sleep mode, it takes a maximum of 30
seconds until the response code is received. If subsequent commands are sent to the projector within 10 seconds, the
projector will reply immediately.
If no further commands are received within 10 seconds, the projector will again return to Deep
Sleep mode. Please note that Deep Sleep mode is only activated in STANDBY MODE. There is no delayed RS-232C
response when the projector is in operation.
•
A special command, POWR???? is available for applications that require continuous polling. This command will not wake the
CPU in Deep Sleep mode and the projector will provide immediate reply in STANDBY mode. “1” will indicate Power on, “0” will
indicate Power off.
When the power is turned on during standby with the “POWER ON” command, wait for at least 30 seconds
after the power has been turned on, and then transmit the next command.
•
We suggest disabling the AUTO SEARCH feature before initiating RS-232C communications. If AUTO SEARCH is enabled,
it will be necessary to send the POWER OFF command “POWR_ _ _0” two times to power down the projector. (The first
“POWR_ _ _0” command cancels AUTO SEARCH and the second “POWR_ _ _0” command will place the projector in
standby mode.)
Note
•
When using the computer control function of the projector, the adjustment values cannot be read by the computer.
Therefore, confirm the values by transmitting the display commands (e.g. “RARE_ _ _0”) for each adjustment menu and
checking the values with the on-screen display. If the projector receives adjustment/setting commands other than menu
display commands, it will execute the commands without displaying the on-screen display.
Commands
Example:
•
When “BRIGHT” of INPUT 1 image adjustment is set to –10.
