Projector Control

There are three methods of externally controlling a projector. (1) Control a single projector using RS232C communication (2) Control multiple projectors using RS485 communication (3) Control multiple projectors using RS232C communication An explanation of each method follows below.

9.1.1. Control a single projector using RS232C communication For this method, connect one projector to the communication port (RS232C communication pin) on a PC to control it. You can control power On/Off or input pin switching. See “9.4 Communication Commands” for more information.

(1) Connection terminal Connects to the RS232C/COM1 terminal on the main board. Use the RS232C/COM1 terminal

*3 : You must set termination by turning ON as a binate the termination of the RS485 converter side and the last device (Projector D in the above connection example) in a daisy chain connection. If you do not set termination correctly, control operation will become unstable. *4 : Stabilize the logic level in communication. If it is “OFF”, a communication error (such as a framing error) will occur on the projector side and control operation will become unstable.

Projector Control

Control multiple projectors using RS232C communication

By performing RS232C communication with one projector, the signal is converted into an RS485 signal and transferred to other projectors. In the previous subsection 9.1.2 RS485 communication, an RS232CRS485 converter is externally set up, but the projector itself performs the conversion processing.

During adjustment, reply time may exceed 10 sec. because the save operation to the memory is in progress. ・ The Projector No. is the communication ID that is set for each projector. You can change the setting as explained below. (A) While pressing the ADJ key on the remote control, press the SUB key to display the menu. (B) Move the menu cursor using the

9.4. Communication Commands

(1) (00H) : Power ON/OFF request (A) Description (i) This command requests a lamp to be activated or deactivated. (ii) A projector immediately replies when receiving a command. The actual lamp activation process is performed after replying to ACK. (iii) Even when replying to ACK, the lamp might not activate if there is a projector fault. Use the Status (20H) command to confirm your understanding of this state. (iv) When not specifying a lamp, performs the activation process on the lamp that was activated during the activation process for the previous lamp. (v) If the inactive information is ON for both lamps, performs the activation process on LAMP1. When specifying the activated lamp, replies to ACK and performs the activation process on LAMP1. (vi) Performs the lamp activation process even if the inactive information for the specified lamp is ON. If the lamp did not activate, lamp switching is automatically performed and the lamp activation process is performed on the other lamp. However, the read request (1EH) for the lamp inactive information flag must check the lamp and the Power ON request must not be performed on the inactive lamp. (B) Command format (i)

Communication Commands

(2) (02H) : Display color ON/OFF request (A) Description (i) This command is set when screen distortion is visible after switching the input signal or when simultaneously performing screen blanking on multiple screens in the Multiscreen mode. (ii) Approximately 4 sec after executing screen blanking (at least one color is OFF), forcibly cancels screen blanking. However, the time required for cancelling screen blanking might increase if a synchronization signal fluctuates or becomes unstable during screen blanking. (iii) NAK replies when the power is OFF. (iv) If there is no signal for the input frequency after the screen blanking request, cancels screen blanking approximately 3 sec later and displays “NO SIGNAL”. Also, if the input frequency is not supported, displays “OUT OF RANGE”. (v) In addition to the previous command formats, this command supports command formats that set the forced cancellation time of screen blanking. This makes it possible to prevent a projector from cancelling blanking on its own when the image switcher, etc needs 3 sec or longer to switch the input. (vi) If a projector is executing processes such as mode switching on its own, screen blanking might not be performed within the specified cancellation time. Incidentally, the target for mode switching is approximately 2 sec, but more time might be required if the synchronization signal is unstable. (vii) The interval for displaying “NO SIGNAL” or “OUT OF RANGE” increases along with the increased cancellation time setting.

Switching the scan mode does not return the setting to the previous values. (iii) This command is even accepted when the power is OFF. However, turning the main power OFF clears the settings. (iv) Settings made during lamp cooling are accepted, but might not take effect depending on the timing. This command makes settings after lamp cooling ends. (v) When decreasing brightness, the brightness-color balance change might vary slightly depending on the individual variation between projectors.

Communication Commands

(5) (1EH) : Lamp Not Lit Information flag read request (A) Description (i) If the lamp did not light, burned out, or was forcibly deactivated because of the cumulative lamp running time, this information is for the bit corresponding to the failed lamp that the projector turned ON. When this flag is ON, it indicates an unlit lamp and the changer does not change the unlit lamp. (ii) To clear this flag, either clear the cumulative lamp running time on the Adjustment screen or write “0” using a write request for the following Lamp Not Lit information flag. Only changing the lamp with a normal lamp does not clear this flag. (B) Command format 02H (STX)

Content Power is OFF

bit1

Lamp activation standby

-

AV control, remote control, or the main power switch turned OFF the power. Lamp cooling process ended, power can be turned ON. Waiting for lamp activation. Projector automatically performs the Retry process. Including Retry, a total of 6 activation processes are performed. Activation wait time is approximately 18 sec. Total time is 108 sec. If the lamp does not activate, status changes to Out of Order (bit4) Maintains “Power is ON (bit5)” in activation processes for lamps not currently in use such as during overlapping activation for alternating activation or when in the Heat Standby state.

bit2

Lamp is cooling

-

After turning power OFF, performs lamp cooling for 60 sec. Does not turn power ON in this state (event disappears). Can turn power ON when the cooling process ends and status transitions to the Power is OFF (bit0) state.

bit3

Changer is running

-

The lamp changer is now in operation. The maximum run time is 10 sec and status transitions to Out of Order (bit4) when a timeout occurs. Cannot execute the power OFF process when the changer is running. Temporarily (for 2-10 sec) transitions to confirm the position of the lamp the power ON process will activate. Maintains “Power is ON (bit5)” during overlapping activation for alternating activation or when in the Heat Standby state.

bit4

Out of Order (Details in bytes 2, 3))

-

Checks the fault content in the Byte No. 2 and 3 information. Projector power is OFF when out of order. To turn the power on again, you must turn AC OFF/ON. Then, you must turn the AV control OFF/ON, and operate the remote control or main power switch.

bit5

Power is ON (Activating lamp) (Details in Byte No. 2, 3)

-

Lamp activated normally. Information in Byte No. 3 indicates a changer communication error, the Lamp Lit state, and the Lamp Not Lit state. With the changer, two lamps might simultaneously light during overlapping activation for alternating activation or when in the Heat Standby state.

Communication Commands

(10) (25H) : Mode write request (A) Description (i) This command switches the mode data by specifying the mode number (see Chapter 8). The mode data stores the adjustment data (color balance or screen zoom information) that was set by a separate remote control. (ii) After data expansion ends, this command automatically cancels blanking. However, this command does not cancel blanking performed using the display color ON/OFF setting command (02H). (iii) Is only valid when the AV controller is not connected and NAK replies when it is connected. When controlling even though the AV controller is connected, the AV controller ID code is 1FH. (iv) NAK replies when performing adjustments. (v) Executes Auto Scan () from the specified scan mode when “AUTO ON/OFF” of the specified mode is set to “ON”. (Does not search areas newer than the specified scan mode.) (vi) For auto scan, the input pins to be searched are the input pins that the specified scan mode sets. Switches to the specified scan mode when the VIDEO input pins are set. (vii) For auto scan, does not measure the frequency approximately 100 ms after the command (25H) is received. Therefore, to switch the video signal, you must control the switching so it ends within 100 ms.

(B) Command format

9 Projector System Setup and Control

(A) Description (i) This command replies when the lamp switch request is accepted. (ii) Projectors perform the lamp activation process (Retry when necessary) required for lamp switching, overlap activation, and changer switching. (iii) If lamp switching could not be executed because of the lamp not activating or a changer malfunction, (a) When there is overlap activation, lamps that were lit prior to the request remain lit. This allows you to use the screen without it going out. (b) When there is no overlap activation, lamps that were lit prior to the request deactivate, so the projector performs the lamp activation process again. (iv) After the lamp switching request, the target time until lamp changing is actually executed is (a) Approximately 2 minutes later when there is overlap activation (set from the menu screen). However, if the lamp is not lit when Retries occur, switching will be delayed approximately 20 sec for each Retry. Lamp switching will therefore be delayed by the time required for Retries (up to 5 times). (b) Switching is executed immediately when there is no overlap activation. This command performs the lamp activation process after lamp switching. (v) This command replies when receiving a request. The projectors perform all remaining processes. This command checks whether lamp changing was actually completed using Status Reply (20H) and the Lamp Unlit Information flag read request (1EH) command. (vi) When the request for switching to Lamp 1 or Lamp 2 matches the currenly lit lamps and changing the lamps is unnecessary, this command only ACK replies. (vii) When a projector sets no overlap activation, the projector replies after performing the Power OFF process. (viii) Overlap Activation ON/OFF is performed using the Adjustments menu with the remote control [SETTINGS] → [LAMP SETTING] → [WARM-UP ON/OFF] (ix) When externally controlling alternating activation, the alternating activation function the projector performs itself is set to “OFF”. Adjustments menu using a remote control: [SETTINGS] → [LAMP SETTING] → [AUTO CHANGE SEL.]
