External control About the external control This monitor has three external control terminals. ● MAKE/TRIGGER terminal (RJ-45): The following external control systems are available. 1 MAKE (make contact) system: Controls the monitor by short-circuiting the corresponding pin terminal to the GND pin terminal, or disconnecting (opening) it. 2 TRIGGER (trigger) system: Controls the monitor by sending the pulse signal instantaneously to the corresponding pin terminal. → "Using the MAKE/TRIGGER system" on the right. ● RS-485 terminal (RJ-45): Controls the monitor with the RS-485 system (→ "Using the serial communication" on page 28). ● RS-232C terminal (D-sub 9-pin): Controls the monitor with the RS232C system (→ "Using the serial communication" on page 28). Set the following items of "REMOTE SETTING" in SET-UP MENU according to the external control terminal and control system (→ "SERIAL TYPE," "PARALLEL TYPE" on page 24). The settings of this unit Control terminal Control system "SERIAL "PARALLEL TYPE" TYPE" setting setting MAKE/ TRIGGER terminal MAKE TRIGGER - MAKE - TRIGGER RS-485 terminal Serial RS-485 RS485 *1 - RS-232C terminal communication RS-232C RS232C *1 - *1 For a monitor connected to a personal computer etc, select the terminal the equipment is actually connected to. For other monitors, select "RS485." Control priority is as follows. MAKE > TRIGGER = serial communication = buttons and menu on the monitor ● You can use external control even when "CONTROL LOCK" is set to "VOL.LOCK" or "ALL LOCK." (→ page 25) ● When the monitor is off (on standby), external control is not available. But certain external controls (starting/terminating communication, turning on the monitor) are available through the serial communication. (→ page 29) You can control the monitor by a personal computer or dedicated controller*2. ● "Using the MAKE/TRIGGER system" on the right. *2 The controller is not commercially available. Consult your dealer if you need it. PC, etc. RS-485 IN or RS-232C RS-485 OUT RS-485 IN ● For the details, see page 28. RS-485 OUT RS-485 IN RS-485 OUT Using the MAKE/TRIGGER system The MAKE/TRIGGER terminal is configured as follows. You can assign a function to each pin terminal in "REMOTE SETTING." (→ "PIN1, PIN2, PIN3, PIN4, PIN5" in "PARALLEL TYPE" on page 24) ● You cannot change the functions assigned to the pin terminals from 6th to 8th. This is a female terminal. Pin No. 1 2 3 4 5 6 7 8 Pin name PIN1 PIN2 PIN3 PIN4 PIN5 TALLY *1 ENABLE *2 GND *1 The 6th pin terminal controls turning on or off the tally lamp (available to control even when the 7th pin terminal is invalid). *2 The 7th pin terminal makes the external control valid/invalid. Make sure to control the terminal by the MAKE system. To assign the functions to the pin terminals For the operation procedure, see page 18. 1 Select "REMOTE SETTING" on the SET-UP MENU. 2 Set "PARALLEL TYPE" to "SET." 3 Select a pin name ("PIN1" - "PIN5") for which you want to assign a function, then select the function you want to assign. For the selectable functions, see the table on page 29. Operation of the external control 1 Set "PARALLEL TYPE" of "REMOTE SETTING" to "MAKE" or "TRIGGER" in the SET-UP MENU. 2 Short-circuit the 7th pin terminal (ENABLE) to the 8th pin terminal (GND) so that the monitor can be controlled by the external control. 3 When the "MAKE" system is selected: Operate each function by short-circuiting the corresponding pin terminal to the 8th pin terminal (GND) or opening it. When the "TRIGGER" system is selected: Operate each function by pulse control, that is shortcircuiting the corresponding pin terminal to the 8th pin terminal (GND) for about 1 second and opening it. ● When changing the input with MAKE system, only one pin terminal must be short-circuited. (Other pin terminals must be opened.) ● When selecting the "TRIGGER" system, you can operate only one function at a time. Operate the functions one by one. 26
