DIGITAL OUTPUTS

Three short-circuit protected outputs are available that can be configured as NPN, PNP
and PP. Using a CBX connection box, the first two outputs are opto-coupled. The mean-
ing of the three outputs can be defined by the user. They are typically used to signal the
data collection result. They are also available to the Host (either serial or Fieldbus) to be
driven independently.
The electrical features of the two outputs are the following:
V
OUT

LOAD
By default, Output 1 is associated with the Partial Read and No Read events, which acti-
vates when the code(s) signaled by the external trigger are not decoded, and Output 2 is
associated with the Complete Read event, which activates when all the selected codes
are correctly decoded. The output signals are fully programmable through DL.CODE.
