Electrical connection
NOTICE
Connections of the functional earth FE
Ensure that the functional earth (FE) is connected correctly. Unimpaired operation is only guar-
anteed when the functional earth is connected properly. All electrical disturbances (EMC cou-
plings) are discharged via the functional earth connection.
Switching input / switching output
The bar code readers of the BCL 200i series are equipped with
• 1 fixed, programmable, opto-decoupled switching input SWI1
• 1 fixed, programmable, opto-decoupled switching output SWO2
The switching input can be used to activate various internal functions of the bar code reader (decoding, au-
toConfig, ...). The switching output can be used to signal the state of the bar code reader and to implement
external functions independent of the superior control.
The switching input/output is configured as follows by default:
• SWI1: Switching input reading gate start/stop (default)
• SWO2: GOOD READ switching output (default)
NOTICE
You can configure the respective function with the help of the webConfig tool.
The external wiring as switching input and switching output is described in the following. The respective
function assignment to the switching inputs/outputs can be found in see chapter 8 "Starting up the device -
Configuration".
