Configuring a CLV490 with command strings
The CLV490 can be parameterized and operated with command strings via the auxiliary in-
terface or the host interface. Parameters which are unknown to the CLV-Setup may be used
providing that the command string convention is followed. This allows, among other things,
the setting of special devices as well as the configuration of new CLV490 parameters (which
are unknown to "CLV-Setup" program) if your version of the CLV490 is older in comparison.
The "CLV-Setup" user interface is based on the command language.
The command language accesses the CLV490’s command interpreter directly. Use this lan-
guage with care. Commands sent to the CLV490 are carried out immediately.
Parameter values changed by commands are at first only activated in the current parameter
set in the CLV490’s RAM. The altered parameter values must be saved to non-volatile me-
mory in the EEPROM (after the changes are made) using a special command. If the values
are not saved, they will be lost when the voltage supply is cut off.
The "CLV-Setup" Terminal Emulator’s online mode makes it possible to parameterize the
CLV490 with command strings directly.

1.
Click on
in the symbol bar.
The Terminal Emulator window opens. The CLV490 is in Reading mode.
2.
Under D
EVICE
M
ODE
, click on the P
ARAMETERIZING
option field.
The CLV490 aborts reading mode. The "Device Ready" LED extinguishes.
CLV-Setup switches the CLV490 into the parameterize mode with a command.
All commands in parameterize mode begin with "3".
3.
Enter the desired command in command line
1
, and press the [Return] key.
The command is sent to the CLV490.
The CLV490 answers with an echo if the command was syntactically correct (in most ca-
ses).
Example:
The command "3?LT" causes the CLV490 to display the parameter values of the rea-
