Controlling the Monitor with a PC (RS-232C)
Advanced operation
This section explains commands for daisy chain connection.
The basic communication procedure is the same as in the
“One-to-one connection with a PC” section.
n
ID numbers
You can assign a unique ID number to each monitor (see
page 24). This allows you to control a particular monitor in a
daisy chain of monitors.
You can assign ID numbers either from the menu screen (using
the remote control) or from the PC using RS-232 cable.
[Example]
ID number: 1 ID number: 2 ID number: 3 ID number: 4
If monitors are connected as shown above, you can
execute commands like “Set the volume of the monitor with
ID 4 to 20”.
When designating ID numbers for a set of monitors linked in a
daisy chain, you should basically avoid any duplication of ID
numbers.
ID numbers do not have to be assigned in ascending order
starting from the PC. They can also be connected as shown
below.
[Example]
ID number: 3 ID number: 2 ID number: 4 ID number: 1
n
Commands for ID control
The command examples shown on this page assume the
following connection and ID number set up.
ID number: 1 ID number: 2 ID number: 3 ID number: 4
IDST ......... A monitor receiving this command sets its own ID
number in the parameter field.
Example:
IDST0001
OK 001 ←
OK 001 ←
The ID number of this monitor is set to 1.
TIPS
You can automatically assign ID numbers by using the IDST
command with the Repeater control (see “Repeater control”
on page 34).
For example, using the command “IDST001+” automatically
sets the ID numbers, as shown below.
[Example]
ID number: 1 ID number: 2 ID number: 3 ID number: 4
IDST001 +
←
ID setting command with repeater control
WAIT
OK 001
OK 001
←

OK 002
←
“OK” response from ID number: 2
OK 003
←
“OK” response from ID number: 3
OK 004
←
“OK” response from ID number: 4 (End)
IDSL ........The parameter of this command sets the ID number
of the monitor. The monitor is subject to the next
command.
Example:
IDSL0002
←
The next command is for the monitor
with ID number: 2.
WAIT
←

OK 001
←
The volume of the monitor with ID
number: 1 (the one directly connected
to the PC) is set to 20.*
* The IDSL command is effective only once, for the
immediately succeeding command.

IDLK ........The parameter of this command sets the ID
number of the monitor. The monitor is subject to all
subsequent commands.
Example:
IDLK0002
←

with ID number: 2.
WAIT

OK 001
←
The volume of the monitor with ID number:
1 (the one directly connected to the PC) is
set to 10. (IDLK is canceled.)
* The IDLK command remains effective until it is
canceled, or power is shut off.
IDCK ........Provides screen display of the ID number currently
assigned to a monitor, and the ID number currently
set for IDLK (if any).
Example:
(After executing IDLK0002)
IDCK0000
←
(Parameter has no meaning.)
ID : 001 IDLK : 002
←
Returned response. The ID
number is also displayed on the
monitor screen.
IDCK000 +
←
Repeater control. (If a command
is used with repeater control, ID
designation using IDSL or IDLK
is canceled.)

n
Repeater control
This system has a function to allow setting of multiple
monitors connected in a daisy chain using a single command.
This function is called repeater control. You can use Repeater
control function without assigning ID numbers.
[Example]
Set 1
Set 2
Set 3
Set 4
* If monitors are connected as shown above, you can
execute a command like “Set all monitors’ input settings to
PC D-SUB”.
E

n
Repeater 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
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.
Example:
VOLM ? ? ? +
WAIT
10 001
WAIT
10 001
Volume settings for all
monitors are returned.
20 002
30 003
30 004
30 003
30 004
TIPS
• If repeater control is used during ID designation (IDSL,
IDLK), the ID designation is canceled.

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
• STANDBY MODE is LOW POWER 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.
