CLV490 Bar Code Scanner

Product description

b) External parameter memory CMC400 in the CDB420/CDM490 Connection

Module

The function of the "Device Ready" and "Read Result" LEDs on the CLV490 when using the

CMC400 as well as the remedy for error messages are described in the CMC400 Operating

Instructions (order no. 8010002, German/English).

See also Chapter 10.3.1 Function of the external parameter memory, Page 10-35.

Start

– continued –

Read Result

– continued –

Green Start option: START WITH EXTERNAL PARAMETERS (default)

• Blinks for approx. 10 s together with "Device Ready"

LED

(see above) or

• Blinks constantly together with the "Device Ready" LED

(see above)

Start option: S

TART WITH COPY INTERN -> EXTERN

• Blinks alternately with "Device Ready" LED for approx. 10 s (see above) or

• Blinks constantly together with the "Device Ready" LED

(see above)

Reading mode Device Ready Green • Lights up constantly

• Extinguishes with new operating mode/function

Sensor Green • Lights up if reading diode active

(The laser diode is activated/deactivated by the reading pulse)

• Lights up constantly in Free-running mode, since the laser diode is constantly

active

Read Result Green LED is linked to the "Result 2" output and indicates the selected result status for the

defined pulse duration of the output.

• Lights up after a successful read (Good Read)

• Lights up if the match code comparison is active, the bar code read matches the

specified match code(s) and the corresponding result output is selected for the

"Result 2" output

Data Yellow • Flickers when the CLV490 transmits data to the host over the host interface

Percentage Sensor Green • Lights up constantly, since Free-running mode is active

evaluation Read Result Green Behavior dependent on the reading quality:

• Extinguishes if reading rate < 30 %

• Blinks twice a second if reading rate 30 % to 70 %

• Blinks five times a second if reading rate 70 % to 90 %

• Lights up constantly if reading rate > 90 %

Adjusting mode Sensor Green • Lights up constantly, since Free-running mode is active

Show RA-limits Sensor Green • Blinks bright/dark alternately, in the frequency with which the scan line is (partially)

masked out

1) We recommend that you check the parameter set manually, e. g. by printing out the entire configuration. For troubleshooting, see also Chapter 8.3.2 LED error messages

for the external parameter memory (connector cover), Page 8-3

2) Stops blinking when you switch from Reading mode to Parameterization mode
