10.9.2 Auxiliary input via terminal interface
If the CLV cannot read a bar code in Reading mode (e. g. if there is no bar code on the
object), the data content of the bar code can be sent subsequently to the host by using the
A
UXILIARY INPUT function. In this way, the sequence of reading results can be completed if
necessary.
The auxiliary input function uses the terminal interface of the CLV exclusively and features
two options:
• manual entry of the data content via the keyboard of a connected terminal or PC
(Terminal Emulation function)
• entry of the bar code using a hand-held reader; forwarding to the CLV via an internal or
external decoder of the device
Fig. 10-12 shows the flow of auxiliary input.
