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. [Note] The only device whose operation was confirmed using the RS485 converter is the TRS-T made by Data Link Co., Ltd. With other converters, the logic level in communication becomes unstable and stable communication control might not be possible. -6

7 .1. Projector Control.1.3. 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.1.2 RS485 communication, an RS232C RS485 converter is externally set up, but the projector itself performs the conversion processing.

10 .3.1. Overview.3. Communication Procedure The communication interface between the external communication device and projectors is formatted so the external communication device always functions as the master and controls the projector Format (1) Format of commands to the projector (A) When individually specifying a projector STX + BC + CMD + PARA + CS + SN STX Start command (fixed to 02H) 1 Byte BC Byte count from CMD to the last byte of PARA 1 Byte CMD Command code 1 Byte PARA * Parameter Variable CS Value when the sum of the lower 8 bits from BC to CS is 0. Two s complement. 1 Byte SN Projector No.. FFH corresponds to all projectors. 1 Byte (B) When sending batch notification to the projector (no response from projector) STX + BC + CMD + PARA + CS + SN + BSN STX Start command (02H) 1 Byte BC Byte count from CMD to the last byte of PARA 1 Byte CMD Command code 1 Byte PARA * Parameter Variable CS Value when the sum of the lower 8 bits from BC to CS is 0. Two s complement. 1 Byte SN Projector No..

Depending on the command, there might be no (PARA) entry and (CMD) might be followed by (CS). -10

11 .3.2. Format.3. Communication Procedure (C) Correspondence between (BSN) bit and Projector No. The 32 bits (4 bytes) of (BSN) can specify 32 units (Projector No. 0-31). To specify broadcast with a Projector No. greater than 31, you can specify a specific projector by making the value which is the Projector No. masked by 1FH (the remainder divided by 32) become (BSN). [Note] During broadcast communication, (BSN) is bit0 for Projector Nos. 0, 32 and 64 for example, so these numbers cannot be distinguished. In RS485 communication where projectors are daisy chained together, you must be sure these projectors do not exist on the same line. Projector No. BSN Projector No. BSN Projector No. BSN 0 bit0 8 bit8 32 bit0 1 bit1 bit 33 bit1 2 bit2 10 bit10 ~ ~ 3 bit3 11 bit11 63 bit31 4 bit4 12 bit12 64 bit0 5 bit5 ~ ~ 65 bit1 6 bit6 30 bit30 ~ ~ 7 bit7 31 bit bit31 (D) Example of (BSN) The following chart shows (BSN) when controlling specific projectors. [Note] (SN) is typically set to FFH. Corresponding Projector No. (SN) (BSN) 0 FFH 00H 00H 00H 01H bit0 is 1 1 FFH 00H 00H 00H 02H bit1 is 1 2 FFH 00H 00H 00H 04H bit2 is 1 3 FFH 00H 00H 00H 08H bit3 is 1 4 FFH 00H 00H 00H 10H Bit4 is 1 1, 2, 3, 4 FFH 00H 00H 00H 1EH bit1, 2, 3, or 4 is 1 31 FFH 80H 00H 00H 00H bit31 is 1-11

12 .3.2. Format.3. Communication Procedure (2) Format of reply commands from projectors (A) When replying to a message (reply to a read request command) STX + BC + CMD + DATA + CS + SN STX Start command (fixed to 02H) 1 Byte BC Byte count from CMD to the last byte of PARA 1 Byte CMD Command code 1 Byte DATA * Reply data variable CS Value when the sum of the lower 8 bits from BC to CS is 0. Two s complement. 1 Byte SN Projector No. 1 Byte In the explanation in subsection.4 Communication commands, parameters might be expressed as (PARA1) or (PARA2). Depending on the command, there might be no (PARA) entry and (CMD) might be followed by (CS). (B) When replying to ACK (reply to a normal received command) ACK + SN ACK Reply command when a command is normally processed (06H) 1 Byte SN Projector No. 1 Byte (C) When NAK replying (command content error, cannot execute process) NAK + STS + SN NAK Reply command when command had an error. (15H) 1 Byte STS Error code 1 Byte SN Projector No. 1 Byte NAK Error Code Code Content Comments 01H 02H 03H - Checksum Command No. Error 04H BUSY Cannot execute process 05H Specification Address Error Memory reads/writes only 06H EEPROM WRITE Error Memory writes only 07H Command Parameter Error (3) Communication rules Timeout results if byte-byte transfer interval exceeds approximately 6ms. Maximum command reply time is 5 sec., except during projector adjustment. 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 or key and select items using the key. Select in the order [SETTINGS] [PROJECTOR NO.]. (C) You can set a value from 0 to 255 using the and keys, but 255 does not function as the ID because all projects will respond in this case. -12

13 .4. Communication Commands (1) (00H) : Power ON/OFF request (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. (i) 02H 02H 00H H H H (STX) (BC) (CMD) (PART1) (CS) (SN) (ii) 02H 03H 00H H H H H (STX) (BC) (CMD) (PART1) (PARA2) (CS) (SN) (C) Command format (broadcast) (i) 02H 02H 80H H H H H (STX) (BC) (CMD) (PART1) (CS) (SN) (BSN) (ii) 02H 02H 80H H H H H H (STX) (BC) (CMD) (PART1) (PART2) (SN) (CS) (BSN) PART1 (1 byte) PART2 (1 byte Specify the activation lamp (only valid for ON requests) 00H : OFF 00H : Lamp 1 01H : ON 01H : Lamp 2 (D) Command example (for Projector No. 1) Power ON Request 02H 02H 00H 01H FDH 01H Power OFF Request 02H 02H 00H 00H FEH 01H (E) Reply to a request command (reply by power state) State Request Command ON OFF Power is OFF ACK only Waiting for lamp activation ACK only Cooling lamp NAK (04H) ACK only Changer is now in operation NAK (04H) NAK (04H) Out of order NAK (04H) ACK only Power is ON (Lamp is activated) ACK Only *04H : NAK code that indicates the BUSY status. -13

14 .4. Communication Commands (2) (02H) : Display color ON/OFF request (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. (v) Also, if the input frequency is not supported, displays OUT OF RANGE. 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. (i) 02H 02H 02H H H H (STX) (BC) (CMD) (PARA1) (CS) (SN) (ii) 02H 03H 02H H H H H (STX) (BC) (CMD) (PARA1) (PARA2) (CS) (SN) (C) Command format (broadcast) (i) 02H 02H 82H H H FFH H (STX) (BC) (CMD) (PARA1) (CS) (SN) (BSN) (ii) 02H 03H 82H H H H FFH H (STX) (BC) (CMD) (PARA1) (PARA2) (CS) (SN) (BSN) PARA1 (1 byte) bit7-bit3 unused bit2 B=1 : ON 0 : OFF bit1 G=1 : ON 0 : OFF bit0 R=1 : ON 0 : OFF PARA2 (1 byte) Blanking time = (PARA2) x 100MS sec (D) Command example (for Projector No. 1) White (full-color display) Request Blank (blanking) Request 5-sec Black Screen request 02H 02H 02H 07H F5H 01H 02H 02H 02H 00H FCH 01H 02H 03H 02H 00H 32H CH 01H -14

15 .4. Communication Commands (3) (0BH) : Brightness data request (i) This command controls brightness from the operation panel. Brightness settings decrease the brightness. (ii) Once set, brightness data is valid unless the power is OFF (the lamp is deactivated) or there is a transition to the Adjustment state (for both repair personnel and regular users). 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. (vi) When setting brightness data, the screen becomes brighter momentarily then dims to the set brightness. (B) Command brightness 02H 04H 0BH H H H (STX) (BC) (CMD) (PARA) (CS) (SN) (C) Command format (broadcast) 02H 02H 8BH H H FFH H (STX) (BC) (CMD) (PARA) (CS) (SN) (BSN) PARA (3 byte) Byte No. 1 : R color 0(dark) - 100(bright) Byte No. 2 : G color Byte No. 3 : B color (D) Command example (for Projector No. 1) 100% Brightness Request 02H 04H 0BH 64H 64H 64H C5H 01H 50% Brightness 02H 04H 0BH 32H 32H 32H 5BH 01H Request *1 *1 : Target brightness is approximately 1/4 of 100% brightness. -15

16 .4. Communication Commands (4) (1CH) : Fault data history read request (i) This command checks the past fault history and the lamp changing history. (ii) You can check the newest information by using the Status information command (20H). 02H 01H 1CH E3H H (STX) (BC) (CMD) (CS) (SN) (C) Reply status format 02H 1H CH H ~ H H FFH (STX) (BC) (STAT) (DATA) (CS) (SN) DATA (8 byte) x 3 times = 24 byte Byte No. 1 : Scan mode : 0-10 Byte No. 2 : Fault information Byte No. 3 : Data Byte No. 4 : Free Byte No. 5-7 : Run time (unit: sec) Latest log (8 Byte) Previous log (8 Byte) Second previous log (8 Byte) (D) Details of Byte No. 2, 3 Information Byte 2 Byte 3 Content Comments 1 1 Lamp not lit 1 2 Lamp not lit 2 - Lamp 1 did not light or is damaged - Including forced deactivation - Lamp 2 did not light or is damaged - Including forced deactivation 2 1 Lamp cover 1 - Lamp 1 was not inserted 2 Lamp cover 2 - Lamp 2 was not inserted 3 - Temperature error - Power turned OFF because of temperature error - In this fault mode, the power unit itself stops, so there is often no reply from a projector 4 bit0-7 Fan stop - Supports bit0=fan1 - bit7 = FAN8 5 - Changer error 6 - Changer internal sensor detection error 7 bit1-3 Circuit power failure 11 - Temporary power blackout - Lamp changing was not complete because communication with the changer did not end normally - Error resulted in the position detection sensor inside the changer - Voltage was not correctly supplied to the drive board - Corresponding bit is Lo (=0) bit1 = 3.3V, bit2 = -10V, bit3 = 2.5V - Power was turned OFF without performing the correct power OFF process -16

17 .4. Communication Commands (5) (1EH) : Lamp Not Lit Information flag read request (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. 02H 01H 1EH E1H H (STX) (BC) (CMD) (CS) (SN) (C) Reply status format 02H 02H EH H H H (STX) (BC) (STAT) (DATA) (CS) (SN) DATA (1 byte) bit0 : Lamp 1 flag (Flag is ON if set to 1 ) bit1 : Lamp 2 flag (Flag is ON if set to 1 ) (6) (1FH) : Lamp Not Lit Information flag write request (i) This command writes to the Lamp Not Lit Information flag. (ii) When Lamp Not Lit Information writes 0 to a bit that is ON, the corresponding cumulative lamp running time and activation count is automatically cleared to 0. Even if Lamp Not Lit Information writes 0 to a bit that is OFF, the cumulative lamp running time and activation count is not cleared. (iii) Also see Lamp Not Lit Information flag read request above. 02H 02H 1FH H H H (STX) (BC) (CMD) (DATA) (CS) (SN) DATA (1 byte) bit0 : Lamp 1 flag (flag is ON if set to 1 ) bit1 : Lamp 2 flag (flag is ON if set to 1 ) (C) Command example (for Projector No. 1) Lamps 1 and 2 are cleared Only lamp 2 is cleared 02H 02H 1FH 00H DFH 01H 02H 02H 1FH 01H DEH 01H -17

20 .4. Communication Commands (8) (21H) : Run time information request (i) This command checks the run time. (ii) The consecutive lit time is cleared to 0 each time the power is turned OFF or the lamp alternating activation function deactivates the lamp. Correspondingly, cumulative run time is the result that includes the consecutive lit time. This value is not cleared to 0 until you intentionally clear it using the Adjust menu or a communication command. 02H 02H 21H H H H (STX) (BC) (CMD) (PART) (CS) (SN) PART (1 byte) 00H 20H 22H 40H 42H Unit Lamp 1 cumulative run time Lamp 1 consecutive lit time Lamp 2 cumulative run time Lamp 2 consecutive lit time (C) Reply status format 02H 05H A1H H H H FFH (STX) (BC) (STAT) (PART) (TIME) (CS) (SN) TIME (3 bytes) : run time (unit: hours) () (24H) : Current mode read request Replies with the current mode number. 02H 01H 24H DBH H (STX) (BC) (CMD) (CS) (SN) (C) Reply status format 02H 02H A4H H H H (STX) (BC) (STAT) (DATA) (CS) (SN) SCAN (1 byte) :

21 .4. Communication Commands (10) (25H) : Mode write request (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. 02H 02H 25H H H H (STX) (BC) (CMD) (PARA) (CS) (SN) (C) Command format (broadcast) 02H 02H A5H H H H H (STX) (BC) (CMD) (PARA) (CS) (SN) (BSN) PARA (1 byte) (mode 0 is for adjustment only) The following modes are for optional video boards. 128, 131 : VIDEO1 (Composite pin input) 12, 132 : VIDEO2 (S pin input) 130, 133 : VIDEO3 (D pin input) (D) Command example (for Projector No. 1) Mode 1 Switching Request 02H 02H 25H 01H D8H 01H Mode 11 Switching Request 02H 02H 25H 0BH CEH 01H -21

23 .4. Communication Commands (13) (75H) : Lamp switch request (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 (v) command performs the lamp activation process after lamp switching. 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.
