Controlling the Monitor with a PC (RS-232C)
Setting of the GAMMA user data
n To transfer the GAMMA user data
Use the user data transfer commands (UGRW, UGGW and
UGBW). For each of the R, G and B colors, divide the total
512 pieces of user data into 16 blocks, and transfer 32 pieces
of data with each command.
C1 C2 C3 C4 P1 P2 P3 P4
… S1 S2
Command field Block number (01 to 16) Data field Checksum field
Example: To transfer the data of block 1 (0 to 31 levels)
of red (R) data
UGRW01000000010002 … 0031C0
Command Block number 32 pieces of data Checksum
One piece of data consists
of 4 digits.
* If data is less than 4 digits, add a “0” (zero) to make it 4
digits.
* The checksum field is the character string (ASCII) data of
lower-order one byte which indicates the sum of the block
number and 32 pieces of data in hexadecimal (0 to F).
n Saving the GAMMA user data
Use the user data save command (UGSV) to save the
transferred user data in the monitor.
If the data is not saved, it will be cleared when:
• The main power switch is off
• POWER SAVE MODE is ON and the monitor enters
standby mode
n Activating the GAMMA user data
To activate the transferred user data, select USER for GAMMA
of the PICTURE menu, or send the corresponding RS-232C
command.
n Checking the GAMMA user data
Use the user data read commands (UGRR, UGGR and
UGBR) to return 512 pieces of user data for each of the R,
G and B colors. Divide the data into 16 blocks and return 32
pieces of data with each command. The value to be returned
is not the value stored in the monitor, but the value in the
temporary memory for display. (These values are the same
when the user data save command (UGSV) above has been
sent.)
TIPS
• The user data is not initialized by RESET of the PICTURE
menu. To initialize the user data, use ALL RESET of the
FUNCTION menu.
The GAMMA user data initialize command (UGRS) allows
the initialization of the user data only.
