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 eld.
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 21).
For example, using the command “IDST001+” automatically
sets the ID numbers, as shown below.

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.
