Operation
Sending a command
You have the option of sending individual commands to the sensor. The
commands are made up of 4-digit hexadecimal numbers (0 ... 9, A ... F). An
overview of the available commands can be found in the appendix.
1. If you are not already on the Settings tab, navigate to it.
2. Enter a valid, 4-digit hexadecimal number for the required command in the
Command field.
3. Click on Send.
The relevant command will be sent to the sensor, where it will be
executed.
Decoder parameters
Settings can be applied to the individual symbologies via the "Decoder
parameters" menu option. The green checkmark and red cross show which
symbologies have been activated and which have not. They can be activated or
deactivated via the respective menus. You can configure settings to the general
operating principle of the sensor via the General settings menu option.
General settings
Any new values entered in a text box are sent to the reader automatically
■
after approximately 1.5 seconds. Pressing the enter key is not absolutely
required.
If an invalid character is entered in a text box (e.g., a letter in a numerical
■
field), the background is highlighted red and the value is not sent to the
reader. If a value outside the validity range is entered, the background is
also highlighted red.
The general settings for operation are entered here.
Trigger signal edge: Configures the inputs for rising edge or falling edge
■
Triggers for edge/level (individual triggers only): Configures the inputs
■
for edge and level sensitivity
Decoder mode: Configuration option of automatic or assisted. If the
■
option automatic is selected, no defined distances between the reader
and the code are adopted. If the option assisted is selected, a fixed read
distance between the reader and code carrier is adopted (refer to the
technical data in the data sheet for the read distance). This defines the size
of the code. However, additional settings are required as a result (reading
window width).
Contrast improvements: The following options can be used to increase
■
the detection reliability of codes and images with low levels of contrast.
Either general linear codes (apart from Interleaved 2/5), just Interleaved
2/5, or both can be activated. Activating these options can result in longer
decoding times and must be assessed on a case-by-case basis.
Average reading window width (mm): The value range is 10 mm ... 200
■
mm. Input of the average reading window width.
