Sharp PN-V602 Controlling the Monitor with a PC RS-232C, NCommands for ID control, NID numbers

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

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

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 35).

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

IDSL ........The parameter of this command sets the ID number

of the monitor. The monitor is subject to the next command.

Example:

to the PC) is set to 20.*

*The IDSL command is effective only once, for the immediately succeeding command.
