Chapter 6 Operating Instructions

CLV490 Bar Code Scanner

Operation

6.5.9 Reading diagnosis

Function of the auxiliary interface. In this mode, the CLV490 outputs the data contents of

all the bar codes that were read – including those that, according to the evaluation criteria,

were not read properly and were thus incorrect – together with the associated reading

diagnosis data via the auxiliary interface. The number of bar codes output can, therefore, be

higher than the number of those that were sent via the host interface in the reading result.

In the default setting, this mode is selected for the auxiliary interface.

Fig. 6-8, Page 6-40 shows the output format of the auxiliary interface.

In the default setting, the CLV490 does not output any reading diagnosis data via the host

interface.

If the reading diagnosis is to remain inactive, this can be set via the A

UXILIARY INTERFACE tab.

1. In the AUXILIARY INTERFACE drop-down list, choose READ DIAGNOSTICS.

2. Perform a download to the CLV490 by clicking in the toolbar.

The D

OWNLOAD PARAMETERS dialog box is then displayed.

3. Choose the P

ERMANENT storage option in the dialog box.

The auxiliary interface is now set to the "Read Diagnostics" mode.

6.5.10 Monitor Host Interface

Function of the auxiliary interface. In this mode, the CLV490 outputs the data traffic of its

host interface via the auxiliary interface. Protocol driver handshakes and protocol-specific

data, such as start and stop characters, are suppressed here. Each data string is displayed

on a separate line on the screen. Two monitoring modes are available that differ with regard

to the data output format (Table 6-25).

The MONITOR HOST INTERFACE or MONITOR HOST INTERFACE 2 function is activated via the

UXILIARY INTERFACE tab.

1. In the A

UXILIARY INTERFACE drop-down list, choose MONITOR HOST INTERFACE or MONITOR

OST INTERFACE 2.

2. Perform a download to the CLV490.

To do so, click the desired option in the list again with the right mouse button and

choose D

OWNLOAD PARAMETER in the context menu.

CLV-Setup copies the parameter to the CLV490 temporarily.

The auxiliary interface then operates in the choosed "Monitor Host Interface" mode until

the CLV490 is switched off again.

Note On good read, the CLV490 only outputs the number of read bar codes being defined for

maximum on the C

ODE CONFIGURATION tab, in the NUMBER OF CODES section.
