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. nCommands 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 nID 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 IDST A monitor receiving this command sets its own ID number in the parameter field. Example: IDST0001 OK 001 ← The ID number of this monitor is set to 1. 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 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 + WAIT OK 001 OK 002 OK 003 OK 004 ← ID setting command with repeater control ← "OK" response from ID number: 1 ← "OK" response from ID number: 2 ← "OK" response from ID number: 3 ← "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 WAIT OK 002 ← The next command is for the monitor with ID number: 2. ← Searching for monitor with ID number: 2 ← Found monitor with ID number: 2 VOLM0030 WAIT OK 002 VOLM0020 ← Sets volume of monitor with ID number: 2 to 30. ← Processing ← OK response from monitor with ID number: 2 ← Sets volume to 20. The volume of the monitor with ID OK 001 ← 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. 33 E

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
←
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” response from ID number: 1
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
←
Searching for monitor with ID number:
2
OK
002
←
Found monitor with ID number: 2
VOLM0030
←
Sets volume of monitor with ID
number: 2 to 30.
WAIT
←
Processing
OK
002
←
OK response from monitor with ID
number: 2
VOLM0020
←
Sets volume to 20.
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.
