The ICR is equipped with three decoders:
•
The decoder for 2-D codes
•
The SMART decoder (

M

A

T

bar codes with a small aspect ratio (ratio of the code height to the code length), bar
codes that are dirty or damaged, as well as bar codes that are tilted excessively
(azimuth angle)
•
The tried-and-tested standard decoder of the CLV series for bar codes
The ICR derives useful diagnosis data from the reading process and transfers it to the host.
It also records operating data that can be requested at any time. The reading quality
of bar codes can be checked in the “Percentage Evaluation“ operating mode. The reading
quality of 2-D codes can be checked using the reading diagnosis data in normal Reading
mode. On request, the ICR outputs the image buffer memory content as binary or grey scale
bitmap via the Ethernet interface.
To start the reading process when an object is located in the reading area, the ICR requires
a suitable trigger. This opens a time window (“reading interval“) in the ICR for the reading
procedure. In the default setting, this trigger is supplied by an external reading pulse sensor.
Alternative trigger sources include Free Running mode and a command sent via the host
interface.
The current operating status is indicated by four LEDs. A beeper indicates the status of the
reading result. In the default setting, the “Good Read“ function is selected for this.
If the trigger is supplied externally by a sensor, the “Sensor 1“ switching input signals the
start of the reading procedure to the ICR. The “Sensor 2“ switching input is used to signal
the end of reading procedure or to enter a path increment. Alternatively, it can be used
e. g. to teach in a match code. The “Result 1“ and “Result 2“ switching outputs can be
assigned various functions and trigger external devices, such as a PLC. Using the “Result 1“
output, an external field illumination can additionally be triggered or directly powered (max.
100 mA) by the ICR.
The ICR is operated and configured via the serial auxiliary interface (auxiliary data interface)
with the user interface of the “CLV Setup“ software or via the host/auxiliary interface and
command strings. Alternatively, the Ethernet interface is available for both types of
operation.
The ICR outputs system and error messages as error codes, which can be requested from
the error memory using command strings.
