(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 22 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.

•Special commands, “POWR????” and “TLPS_ _ _1” are available for applications that require continuous polling. These commands 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 STANDBY mode. When the power is turned on during standby with the “POWER ON” command, wait for at least 40 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 STANDBY mode 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 put the projector into the standby mode.)

Note

•Do not repeatedly or periodically send any commands other than “POWR????” and “TLPS_ _ _1” in STANDBY mode as it will cause problems.

•When the projector is put into the standby mode, a message “Shutting Down. Please Wait.” is displayed for about 20 seconds. At that time, if the “POWR_ _ _1” command is being sent, “ERR” will be returned and this command is not received.

•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.
