Chapter 10 Operating Instructions

CLV490 Bar Code Scanner

Appendix

Deflection angle

Angle about each side of the center position CW = 50 (equal to 0°) that the Ö scan line

sweeps when it is deflected by the oscillating mirror. Also referred to as the oscillating angle.

Deflection range

Deflection of the scan line caused by the Ö oscillating mirror, perpendicular to the scan

direction about the center position CW = 50 at each side (corresponds to a deflection angle

of 105°). Also referred to as oscillating amplitude. The maximum deflection range is set in

SCILLATING WITH FIXED AMPLITUDE mode. In OSCILLATING WITH VARIABLE AMPLITUDE mode, the

deflection range is set for each distance configuration using the O

SCILLATING MIRROR tab in

the "CLV-Setup" program.

Distance configuration

Data record in the CLV490 for defining a Ö focus position for the laser beam for Ö dynamic

focus control. The focus position as well as the maximum and minimum Ö reading angle

must be entered on the R

EADING CONFIGURATION tab in the "CLV-Setup" program for this pur-

pose. In the case of the line scanner with oscillating mirror, the Ö oscillating amplitude

(deflection range) is also required. The depths of field for the individual focus positions are

shown as a function of the resolution values in the specification diagrams.

Download

Method of transferring the Ö parameter set that was modified with the Ö CLV-Setup pro-

gram offline from the PC to the CLV490. CLV-Setup either always transfers a complete copy

to the memory (RAM) of the CLV490 (D

OWNLOAD TO CLV) or just the parameter previously

processed using the context menu of the right mouse button (D

OWNLOAD PARAMETER) or all

parameters of the displayed tab (D

OWNLOAD PARAMETERS OF THIS VIEW). You can overwrite the

existing parameter set in EEPROM of the CLV490 by choosing the "Permanent" save option.

Dynamic focus control

Function for shifting the focal point of the laser beam across a wide range in the reading

plane. The dynamic focus control function is event controlled (e. g. by the distance detector)

or dynamic in the Ö Autofocus function.

Error messages

Messages in Ö plain text or coded (3-digit) that are used to identify a malfunction on the

CLV490 in Reading mode. The messages are output on the auxiliary interface only. Excep-

tion: ST = 3 (device error), which is also output on the host interface. The error messages

can be displayed in the Terminal emulator in the "CLV-Setup" program.

Error status

Identifier output with the reading result by the CLV490 for errors that were diagnosed while

the bar code was being read. The entry for the host interface is made in the "Code-Info/

Separator" block of the Ö data output string and must be enabled using the parameters (for

the CLV490 disabled by default).

Focus position

Distance of the focal point of the emitted laser beam in front of the reading window. Can be

varied using the optical components in the CLV490. Creates a distance-specific depth of

field (DOF) in which he bar code can be detected.
