8.6.1

Decoding and processing the read data

The device offers the following possibilities:
• Setting the number of code labels to be decoded for each reading gate (0 ... 99). This is done via the
Max. no. of labels parameter.
• Setting the Search mode in which the system is to search for the codes (see chapter 8.6.5 "Optimizing
reading performance").
• Fast
• Optimized
• Robust
• Further parameters can be set for many code types, e.g.
• Code type (symbology)
• Number of digits
Either a number of digits, e.g., 10, 12, 24, or a number of digits range, e.g., 8 ... 22
• Check digit method used for decoding as well as the type of check digit transmission for the output
of the read result.
Standard: corresponds to the standard for the selected code type/symbology
Not standard
Ä Define at least one code type with the desired settings.

8.6.2

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 7.2
"PWR / SWIO – voltage supply / RS 232/RS 422 / switching inputs/outputs").
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 (AUTO function)
• Start alignment mode
Ä Connect the required control devices, e.g., photoelectric sensor, proximity switch, etc., to the device
(see chapter 7 "Electrical connection").
Ä Configure the connected switching inputs according to your requirements.
ð First set the I/O mode to input.
ð Then configure the switching behavior.
ð webConfig tool: Configuration > Control > Digital I/Os
NOTICE
Alternatively, depending on the camera operating mode, you can activate decoding using the +
online command and deactivate it using the – online command (see chapter 11.1 "Online com-
mands").
