nRepeater control command

Repeater control is achieved by setting the FOURTH CHARACTER of the parameter to “+”.

Example:

VOLM030 +

← Sets volume of all monitors to 30.

In repeater control, responses are returned by all the connected monitors.

If you want to determine that a value has been returned by a specific set, assign ID numbers to each monitor in advance. When some monitors do not return their responses, the probable cause is that the monitors could not receive the command or command processing is not complete. Do not send a new command.

Example: (When 4 monitors are connected, and assigned ID numbers: 1 through 4)

VOLM030 +

WAIT

OK 001

OK 002

OK 003

OK 004 ← If 4 monitors are connected in a chain, reliable operation can be ensured by sending a new command only after a reply has been returned by 4th (last) monitor.

Repeater control can also be used for reading settings.

Setting of the GAMMA user data

nTo 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

One piece of data consists

of 4 digits.

Command Block number 32 pieces of data

Checksum

*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).

nSaving 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

•STANDBY MODE is LOW POWER and the monitor enters standby mode

Example:

VOLM ? ? ? +

WAIT

10001

20002

30003

30004

Volume settings for all monitors are returned.

nActivating 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.

nChecking 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.
