Quick start
6.3.1
Starting up the ICR for test reading with the factory default setting
For simple test reading, a PC need not be connected when the ICR is operated with the
factory default setting. No read result will be displayed.
Note
In the default setting, the ICR
only
reads DataMatrix ECC 200 oodes (free symbol length,
square data field, white background).
1.
Connect the ICR to the SICK CDB 420 or CDM 420 Connection Module.
2.
Connect the reading pulse sensor (e.g. photoelectric reflex switch) to the “Sensor 1“
switching input of the ICR via the CDB 420 or CDM 420 (see
the “Sensor 1“ switching input“, Page 5-13
3.
Switch on the power supply to the CDB 420 or CDM 420.
After the ICR has been started and has successfully completed the self-test, it outputs
a tone and then two consecutive tones shortly afterwards when the Reading mode is
initiated. The “Device Ready“ LED lights up. The “Result 1“ (“Device Ready“) output
switches.
4.
Start the reading pulse: block the light path of the photoelectric switch or close the
switch. The “Laser On“ LED lights up. The ICR switches the red, pulsed illumination field
on for lighting the reading area.
5.
For 2-D code reading, represent the sample from
at following reading distance
(no conveyor movement during reading!):
ICR 840 (standard type): 80 mm (3.15 in) for side/front reading window.
At this reading distance the ICR provides a reading area size of 40 mm x 32 mm
(1.58 in x 1.26 in). For assigning the reading area to the reading window see
).
6.
End the reading pulse: unblock the light path of the photoelectric switch or open the
switch.
The “Laser On“ LED extinguishes and the ICR switches off the red illumination field.
The ICR confirms that the bar code was read successfully by outputting a tone via the
beeper. The “Result“ LED lights up for duration of 100 ms. The “Result 2“ (“Good
Read“) output switches for the duration of 100 ms.
The ICR can now be operated with the factory default setting.
The device can be switched off without the configuration data being lost, as no changes
have been made to the parameter set.
