*5 While controlling with the MAKE system, the wave form monitor and vector scope is switched between displayed (short-circuting) and hidden (opening) regardless of the “AUTO OFF” setting in the MAIN MANU. While controlling with the TRIGGER system, the screen is switched in the same way as when pressing the SCOPE button (☞ e on page 6). If the wave form monitor and vector scope are input at the same time, the wave form monitor is displayed.

*6 While controlling with the MAKE system, the screen is switched between normal screen (opening) and blue screen (short-circuiting). While controlling with the TRIGGER system, the screen changes in the same way as when pressing SCREENS CHECK button (☞ q on page 6).

*7 Must be controlled with the TRIGGER system. The mode changes in the order of “NORMAL” \ “CINEMA” \ “FIELD.” (This function cannot be controlled with the MAKE system.)

•You cannot assign the same function to different pin terminals.

•The TRIGGER system switches each function by short-circuiting the pin terminal for about 1 second and opening it.

7Using the serial communication

You can control the monitor from a personal computer etc. via the RS-485 or RS-232C terminal.

• Consult your dealer for the details of the external control specification.

<Communication specifications>

*1 Selects which functions in “MARKER” are activated, non-“R-” items or “R-” items (☞ “MARKER” on page 13). *2 Displays the information shown when INPUT SELECT button of the current input is pressed (☞ “On the Status

Display” on page 7). While controlling with the MAKE system, the information is displayed only at the moment of short-circuiting.

*3 While controlling with the MAKE system, the level meter is switched between displayed (short-circuiting) and hidden (opening). When “LEVEL METER ch” is set to “OFF,” the level meter is not displayed (“NO EFFECT” appears).

While controlling with the TRIGGER system, the pattern of the audio channel display is switched.

*4 While controlling with the MAKE system, the available set-up options will be the setting value currently selected in “SOURCE ID” (“ON” or “AUTO” [short-circuiting]) and “OFF” (opening). While controlling with the TRIGGER system, uses the same set-up option as those in the SET-UP MENU (☞ “SOURCE ID” in “INFORMATION” on page 19).
