7. Confirm the dialog box by selecting the PERMANENT save option.
The CLV outputs the selected elements in the data output string of the host interface
with the next reading result.
6.5.8 Auxiliary input
Function of the terminal interface. In this mode, the CLV accepts a bar code entered at the
terminal interface (via the keyboard or hand-held scanner with decoder). It sends the bar
code to the host in a separate data string via its host interface. No reads can, therefore, be
corrected by transmitting missing bar codes subsequently.
Chapter 10.9.2 Auxiliary input via terminal interface, Page 10-31 describes this function and
the associated procedure in greater detail.
6.5.9 Self-test
After the CLV has been switched on, it performs a self-test before it is initialized with the
parameter set. The test can be called up explicitly at any time via CLV Setup. During the self-
test, the CLV checks that its hardware components are functioning correctly. A final
message via the terminal interface provides information on the test result. The CLV does not
output a reading result during the test routine.
1. Click in the toolbar.
The terminal emulator window is then displayed.
The CLV is in reading mode.
2. Click SELF TEST under DEVICE MODE.
The "Device Ready" LED is extinguished. The CLV cancels the reading mode and starts
the test routine.
After a few seconds, the CLV outputs the encoded test result in the form of a code
number (
Fig. 6-10).
3. To return to the reading mode, activate READING MODE or close the terminal emulator.
The CLV returns to reading mode. The "Device Ready" LED lights up.
