Control of the decoding
In general, decoding is controlled via the configurable switching inputs/outputs. The corresponding connec-
tion to the PWR / SWIO interface must be configured as a switching input for this purpose (see chapter 6.1
"PWR/SWIO (supply voltage, switching input and switching output)").
Controlling decoding via a switching input:
• Start/stop decoding
• Start decoding and then stop decoding after a configurable time period
• Read in a reference code
• Start automatic code type configuration (AutoConfig)
Ä
Connect the required control devices, e.g., photoelectric sensor, proximity switch, etc., to the device
(see chapter 6 "Electrical connection").
Ä
Configure the connected switching input according to your requirements.

NOTICE
Alternatively, you can activate decoding using the '+' online command and deactivate it using
the '–' online command (see chapter 9 "Online commands").
Advanced decoding control in the webConfig tool
The webConfig tool provides advanced functions, in particular for deactivating decoding. These may be ac-
cessed via the
Control
submenu of the
Configuration
main menu. You can:
• Activate decoding automatically (delayed).
• Stop decoding after a maximum reading gate time.
• Stop decoding via the completeness mode, if:
• The maximum number of bar codes to be decoded has been decoded.
• A positive reference code comparison has taken place.
8.3.3
Control of the switching output
By using the switching inputs/outputs of the device, external event-controlled functions can be implemented
without assistance from the superior process control. For this purpose, the respective connection at the
PWR / SWIO interfaces must be configured as a switching output (see chapter 6.1 "PWR/SWIO (supply
voltage, switching input and switching output)").
A switching output can, for example, be activated according to the following criteria:
• At the start/end of the reading gate
• Depending on the read result:
• Reference code comparison positive/negative
• Read result valid/invalid
• Depending on the state of the device:
• Device ready/not ready
• Data transmission active/not active
• Active/standby
• Error/no error

Connect the required switching output (see chapter 6 "Electrical connection").
