Operation

Note The CLV only outputs several bar codes in the reading result if the parameterized minimum

and maximum number of bar codes is > 1, and several bar codes have been presented to

it. The number of bar codes to be read/output for each reading interval can be selected in

the C

ODE

ONFIGURATION

tab in the N

UMBER

ODES

section.

The reading result of the host interface can also be displayed.

Interface, Page 6-29

describes the procedure for this and the structure of the reading

result in the default setting.

Fig. 6-7: Reading result of the terminal interface: structure for Good Read

Good Read:

TT=_ _130 ms MG=_65 % n=_1 AK=1

0123412345

C39 100% ST=0 CL=10 CP=_44 CD=_631 CS=_ _3 CA=_ _3 CK=_ _3 DI=F

PO=–_43 OW=+_ _0 FC=_480 CX=_890 CY=_553 CZ=1481

With:

1st. line : TT = Duration of the reading interval

MG = Temporal mean value of the identification quality

n = Number of detected bar codes

AK = No. of the used distance configuration

2nd. line: 0123412345 = Data contents of the bar code

3rd. line: C39 = ID: Code type Code 39 along

_99% = Identification quality

ST = Read status (ST = 0: Good Read)

CP = Code position

CL = Code length (number of characters)

CA = Scan effort

CS = Code reliability

CK = Code continuity

DI = Decoding direction (F = in scanning direction, R = against

scanning direction

4th line PO = Exact code position (3-digit for tracking)

OW = Exact oscillating angle (3-digit for tracking)

FC = Current focus position (4-digit for tracking)

CX = X-coordinate of bar code (for OTS in transport direction)

CY = Y-coordinate of bar code (for OTS across to transport

direction)

CZ = Z-coordinate of bar code (for OTS from above directly)

1) not relevant for autofocus function

Fig. 6-8: Reading result of the terminal interface: structure for No Read

No Read:

TT=_ _ 240 ms MG=_64 % n=_0 AK=1

no code!

1st. line : TT = Duration of the reading interval

MG = Temporal mean value of the identification quality

n = Number of codes detected

AK = No. of the distance configuration used

2nd. line: no code! = No. bar codes found!

1) not relevant for autofocus function
