Controlling the Monitor with a PC (RS-232C)
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
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.
IDLK ........The parameter of this command sets the ID
number of the monitor. The monitor is subject to all subsequent commands.
Example:
IDLK0002 | ← | Following commands are 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 |

TIPS
You can automatically assign ID numbers by using the IDST command with the Repeater control (see “Repeater control” on page 33).
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
VOLM0020 ←
WAIT
OK 002 IDLK0000 ←
WAIT ← OK 002 ← VOLM0010
OK 001 ←
Sets volume of monitor with ID number: 2 to 20.*
Canceling fixed ID number setting Canceling IDLK
Cancelation complete
The volume of the monitor with ID number: 1 (the one directly connected to the PC) is set to 10. (IDLK is canceled.)
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.
*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.) | |
|
| Returned response. The ID |
ID : 001 | IDLK : 002 | ← number is also displayed on the |
|
| monitor screen. |
IDCK000 + | ← Repeater control. (If a command | |
WAIT |
| is used with repeater control, ID |
| designation using IDSL or IDLK | |
ID : 001 IDLK : 000 | is canceled.) | |
| ||
ID : 002 IDLK : 000 |
| |
ID : 003 | IDLK : 000 |
|
ID : 004 | IDLK : 000 |
