Press TIPS MENU to return to the normal screen. · When both abnormal temperature and hardware error are detected, the hardware error notification overrides. 17 E Controlling the Monitor with a PC (RS-232C) You can control this monitor from a PC via RS-232C (COM port) on the PC. You can also connect multiple monitors via a daisy chain by using a PC. By assigning ID numbers to each monitor (see page 19), you can make input mode selection/adjustment or can check the status of a specific monitor. Precautions when the PN-ZB01 (optional) is attached · To control the monitor via RS-232C, set RS-232C/LAN SELECT to RS-232C. · You cannot use RS-232C and LAN control simultaneously. Communication conditions Set the RS-232C communication settings on the PC to match the monitor's communication settings as follows: Baud rate Data length Parity bit * 8 bits None Stop bit Flow control 1 bit None PC connection nOne-to-one connection with a PC Connect with RS-232 straight cable between the PC's COM port (RS-232C connector) and the RS-232C input terminal on the monitor. * Set to the same baud rate as the BAUD RATE setting of SETUP menu. (Initial setting: 9600 bps) * When connecting multiple monitors in a daisy chain, set all monitors to the same BAUD RATE. Communication procedure nCommand format When a command is sent from the PC to the monitor, the monitor operates according to the received command and sends a response message to the PC. Return code C1 RS-232C input terminal C2 C3 C4 P1 P2 P3 P4 Command field (4 prescribed alphanumerical characters) PC Parameter field (4 character string comprised of: 0-9, +, -, space, ?) To COM port Example: VOLM0030 VOLM 30 * Be sure to input 4 characters for the parameter. Pad with spaces (" ") if necessary. (" " is a return code (0DH, 0AH or 0DH)) Wrong : VOLM30 Right : VOLM 30 When inputting a negative value, specify a numerical value in three digits. Example: AUTR-009 Do not use spaces for MPOS, DATE, and SC01 through SC08. Specify parameters using a specified number of characters. In this case, a value will be returned if you wait a while. Do not send any command during this period. No ID number is attached to WAIT response. When one of the following commands is used: RSET, INPS, ASNC, WIDE, EMAG, EPOS, PXSL, POWR, AGIN, MWIN, MWIP, MWPP, ESTG, EMHV, EPHV, ESHV When control via RS-232C is locked (to prevent use) using the operation lock function (see page 17) L O C K E D Return code (0DH, 0AH) You can assign a unique ID number to each monitor (see page 11). This allows you to control a particular monitor in a daisy chain of monitors. You can assign ID numbers either from the menu screen (using the remote control) or from the PC using RS-232 cable. [Example] ID number: 1 ID number: 2 ID number: 3 ID number: 4 If monitors are connected as shown above, you can execute commands like "Set the volume of the monitor with ID 4 to 20". When controlling monitors linked in a daisy chain by designating ID numbers, you should basically avoid any duplication of ID numbers. ID numbers do not have to be assigned in ascending order starting from the PC. They can also be connected as shown below. [Example] ID number: 3 ID number: 2 ID number: 4 When RS-232C/LAN SELECT is set to LAN U N S E L E C T E D Return code (0DH, 0AH) ID number: 1 19 E Controlling the Monitor with a PC (RS-232C) nCommands for ID control ID number: 1 ID number: 2 The command examples shown on this page assume the following connection and ID number set up. ID number: 3 ID number: 4 IDLK . . . . . . . . The parameter of this command sets the ID number of the monitor. [. . . ] · Load noises from outside may be interfering with normal operation. Turn off the power and turn it on after waiting at least 5 seconds, and then check the operation. · When the AUTO INPUT CHANGE is ON and no signal is present in a selected input mode, the AUTO INPUT CHANGE automatically changes the selected mode to a mode where a video signal is present. The input mode may change in the following cases: - When a computer is in standby mode. [. . . ]
