Perform a download to the ICR845-2. This is done by clicking
in the toolbar.
The D

The auxiliary interface is now set to the "Reading Diagnosis" mode.
6.9.5
Monitor Host Interface
Function of the auxiliary interface. In this mode, the ICR845-2 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 (
Table 6-9
). Each data string
is displayed on a separate line on the screen.
Important
The data communication of the auxiliary interface can also be routed via the Ethernet inter-
face. The serial auxiliary interface (RS 232) will then become disabled. See
Chapter 5.5.5
Connecting the Ethernet interface, Page 40
.
"Monitor Host Interface" is activated via the A

CLV-Setup copies the parameter temporary to the ICR845-2.
The auxiliary interface then operates in "Monitor Host Interface" mode until the ICR845-
2 is switched off again.
Important
On Good Read, the ICR845-2 only outputs the number of read bar codes being defined for
maximum on the C

Displaying the data traffic of the host interface in the Terminal Emulator
The data traffic of the host interface can be displayed in the Terminal Emulator of CLV-Set-
up.
Fig. 6-25
shows an example of how the reading result can be output.
