C431 /C501 /C551 when using an external controller.

2.1 RS-232C Remote control Connector: 9-pin D-Sub Cable: Cross (reversed) cable or null modem cable (Please refer “Controlling the LCD monitor via RS-232C Remote control” on User’s manual.) 2.2 LAN control Connector: RJ-45 10/100 BASE-T Cable: Category 5 or higher LAN cable (Please refer “Controlling the LCD monitor via LAN control” on User’s manual.)

3. Communication Parameter 3.1 RS-232C Remote control (1) Communication system Asynchronous (2) Interface RS-232C (3) Baud rate 9600bps (4) Data length 8bits (5) Parity None (6) Stop bit 1 bit (7) Communication code ASCII 3.2 LAN control (1) Communication system TCP/IP (Internet protocol suite) (2) Interface Ethernet (CSMA/CD) (3) Communication layer Transport layer (TCP) * Using the payload of TCP segment. (4) IP address (Default) Automatic setup * If you need to change, Please refer “Network settings” on User’s manual. (5) Port No. 7142 (Fixed) (Note) The monitor will disconnect the connection if no packet data is received for 15 minutes. And the controller (PC) has to re-connect to control the monitor again, after 15 minutes or more. 3.3 Communication timing The controller should wait for a reply packet before the next command is sent. (Note) When the following commands are sent, a controller should wait for specified period after receiving the reply command before sending the next command.  Power On, Power Off: 15 seconds  Input, Auto Setup, Factory Reset: 10 seconds

The command packet consists of four parts, Header, Message, Check code and Delimiter. Note: Don't add extra data (Example: padding data) after Delimiter. Recommended sequence of a typical procedure to control a monitor is as follows, [A controller and a monitor, two-way communication composition figure] ■ For the general command (see the part "6.3. Operation Code (OP code) Table”) ■ For the special command (see the part 7 to 24. and 5.5.2) Header Message Check Code Delimiter Monitor Controller Get Parameter Get Parameter Reply Set Parameter Set Parameter Get Parameter Reply Save Current Setting Command Get Parameter The controller sends command to get a value from the monitor that you want to change. The monitor replies a current value of the requested item. The controller sends commands to set an adjusted value. The monitor replies to the controller for confirmation. The controller sends command to get a value for confirmation. The monitor replies an adjusted value. The controller requests to store the adjusted value to the monitor. Command Command Reply The control does not suitable for above fixed protocol; use the proper command for each control. Please refer section 5.5 and section 7 to 26. The monitor replies a proper message defined for each Save Current Setting Command Reply The monitor replies to the controller for confirmation. Monitor Controller

1stbyte) SOH: Start of Header ASCII SOH (01h) 2ndbyte) Reserved: Reserved for future extensions. On this monitor, it must be ASCII '0'(30h). 3rdbyte) Destination: Destination equipment ID. (Receiver) Specify a commands receiver’s address. The controller sets the “MONITOR ID” or “GROUP ID” of the monitor controlled in here. On the reply, the monitor sets ‘0’ (30h), always. “MONITOR ID”, “GROUP ID” to “Destination Address” conversion table is as follows, Monito r ID Destinatio n Address Monito r ID Destinatio n Address Monito r ID Destinatio n Address Monito r ID Destinatio n Address 1 41h(‘A’) 26 5Ah(‘Z’) 51 73h 76 8Ch 2 42h(‘B’) 27 5Bh 52 74h 77 8Dh 3 43h(‘C’) 28 5Ch 53 75h 78 8Eh 4 44h(‘D’) 29 5Dh 54 76h 79 8Fh 5 45h(‘E’) 30 5Eh 55 77h 80 90h 6 46h(‘F’) 31 5Fh 56 78h 81 91h 7 47h(‘G’) 32 60h 57 79h 82 92h 8 48h(‘H’) 33 61h 58 7Ah 83 93h 9 49h(‘I’) 34 62h 59 7Bh 84 94h 10 4Ah(‘J’) 35 63h 60 7Ch 85 95h 11 4Bh(‘K’) 36 64h 61 7Dh 86 96h 12 4Ch(‘L’) 37 65h 62 7Eh 87 97h 13 4Dh(‘M’) 38 66h 63 7Fh 88 98h 14 4Eh(‘N’) 39 67h 64 80h 89 99h 15 4Fh(‘O’) 40 68h 65 81h 90 9Ah 16 50h(‘P’) 41 69h 66 82h 91 9Bh 17 51h(‘Q’) 42 6Ah 67 83h 92 9Ch 18 52h(‘R’) 43 6Bh 68 84h 93 9Dh 19 53h(‘S’) 44 6Ch 69 85h 94 9Eh 20 54h(‘T’) 45 6Dh 70 86h 95 9Fh 21 55h(‘U’) 46 6Eh 71 87h 96 A0h 22 56h(‘V’) 47 6Fh 72 88h 97 A1h 23 57h(‘W’) 48 70h 73 89h 98 A2h 24 58h(‘X’) 49 71h 74 8Ah 99 A3h 25 59h(‘Y’) 50 72h 75 8Bh 100 A4h ALL 2Ah(‘*’) Group ID Destination Address Group ID Destination Address Group ID Destination Address Group ID Destination Address A 31h(‘1’) D 34h(‘4’) G 37h(‘7’) J 3Ah(‘:’) B 32h(‘2’) E 35h(‘5’) H 38h(‘8’) C 33h(‘3’) F 36h(‘6’) I 39h(‘9’) Header Message Check code Delimiter SOH Reserved '0' Destination Source Message Type Message Length 1st 2nd 3rd 4th 5th 6th -7th

address 'A'(41h). If you want to control all of the monitors which are connected by a daisy chain, specify a destination address ‘*’(2Ah). 4thbyte) Source: Source equipment ID. (Sender) Specify a sender address. The controller must be ‘0’ (30h). On the reply, the monitor sets the own MONITOR ID in here. 5thbyte) Message Type: (Case sensitive.) Refer to section 4.2 “Message block format” for more details. ASCII 'A' (41h): Command. ASCII 'B' (42h): Command reply. ASCII 'C' (43h): Get current parameter from a monitor. ASCII 'D' (44h): "Get parameter" reply. ASCII 'E' (45h): Set parameter. ASCII 'F' (46h): "Set parameter" reply. 6th -7th bytes) Message Length: Specify the length of the message (that follows the header) from STX to ETX. This length includes STX and ETX. The byte data must be encoded to ASCII characters. Ex.) The byte data 3Ah must be encoded to ASCII characters '3' and 'A' (33h and 41h). The byte data 0Bh must be encoded to ASCII characters '0' and 'B' (30h and 42h).

“Message block format” is allied to the “Message Type” in the “Header”. Refer to the section 4.1 “Header block format” for more detail. 1)Get current parameter The controller sends this message when you want to get the status of the monitor. For the status that you want to get, specify the “OP code page” and “OP code”, refer to “Appendix A. Operation code table”. “Message format” of the “Get current parameter” is as follows,  Refer to section 5.1 “Get current parameter from a monitor.” for more details. 2)Get Parameter reply The monitor will reply with the status of the requested item specified by the controller in the “Get parameter message”. “Message format” of the “Get parameter reply” is as follows,  Refer to section 5.2 “Get parameter reply” for more details. 3)Set parameter The controller sends this message to change a setting of the monitor. Message format of the “Set parameter” is as follows,  Refer to section 5.3 “Set parameter” for more details. 4)Set Parameter reply The monitor replies with this message for a confirmation of the “Set parameter message”. Message format of the “Set parameter reply” is as follows,  Refer to section 5.4 “Set parameter reply” for more details. 5)Command “Command message” format depends on each command. Usually, this “command message” is used for some non-slider controls and some special operations, such as “Save current settings”, “Get timing report”, “power control”, “Schedule”, etc. Refer Header Message Check code Delimiter STX OP code page OP code ETX Hi Lo Hi Lo STX Result OP code page OP code Type Max value Current Value ETX Hi Lo Hi Lo Hi Lo Hi Lo MSB LSB MSB LSB STX OP code page OP code Set Value ETX Hi Lo Hi Lo MSB LSB STX Result OP code page OP code Type Max value Requested setting Value ETX Hi Lo Hi Lo Hi Lo Hi Lo MSB LSB MSB LSB

6)Command reply The monitor replies to a query from the controller. “Command reply message” format depends on each command. Refer to section 5.5 “Commands message” for more details.

Check code is the Block Check Code (BCC) between the Header and the End of Message except SOH. Dn+1 = D1 XOR D2 XOR D3 XOR ,,, Dn XOR: Exclusive OR Following is an example of a Check code (BCC) calculation.
