RS-232C adjustment mode

5.4 RS-232C adjustment mode
The main body is equipped with an RS-232C port to allow different operations using an external PC, including adjustment
of picture quality, white-balance, and phase.

5.4.1 Precaution

• The contents of adjustment are placed in last-memory with the <AJN> command.
Once adjustments are complete, perform <AJN>. The display for screen adjustment disappears.
• Some RS-232C commands can be used in normal mode (during normal operation). Refer to "5.4.3, RS-232C commands
table"
• The system automatically exits RS-232C command mode when one of the following occurs:
a) The main power switch is turned off.
b) STANDBY status is invoked.
c) Any button on the operation panel is pressed.
d) Input signals are externally switched over, or a no-signal status arises.
e) The MENU button is used to switch to MENU mode.
f ) While in KEY LOCK status, buttons on the operation panel or the remote control are pressed.
g) The protective (P.D.) circuit is activated.
Note: For a) and g), only the item currently being adjusted is not placed in last memory.
• Space in the unit's RS-232C communications buffer is limited. When many commands are sent in one communication,
the system may not receive all commands or function properly.
