The bar code scanner works as follows in controlling the laser diodes:
• The bar code scanner has monitoring switches that deactivate the laser diode if irregu-
larities occur in the radiation emission.
• The reading pulse (pulse source) controls the on and off mechanism of the laser diode
during the reading process.
• During reading operation with "Sensor" and "Command" reading pulses, each time level
(laser timeout) switches off the laser diode automatically after 10 minutes (default set-
tings) when a permanent reading pulse has been started. However, it does not stop the
reading pulse.
The reading pulse can be stopped via an appropriate clock signal. The successive rea-
ding pulse switches on the laser diode.
• In SOPAS-ET on the "Illumination control" tab you can set or deactivate the laser timeout
within a range of 1 ... 1,500 min (= 25h).
• "Laser" LED:
During normal reading operation the "Laser" LED lights up when the laser diode is swit-
ched on.
When calling up functions via the two buttons of the bar code scanner (aborting normal
reading operation), the LEDs have got additional display functions. The "Laser" LED will
differ from its original function. It is possible that the "Laser" LED is flashing when Auto-
setup is selected, although the laser diode is still switched off or the laser diode is swit-
ched on, for example, in diagnostic mode (Read Diagn) and the "Laser" LED, however,
is not flashing.
2.4 Quick stop and quick restart
The bar code scanner can be switched on or off using the main switch for connection mo-
dules CDB620 or CDM420.
2.4.1 Switching off the bar code scanner
Switch off the power supply to the bar code scanner (the connection module)
- or -
Remove (pull out) the 15-pole D-Sub-HD connector of the bar code scanner's connec-
tion cable from the connection module.
When the bar code scanner is switched off, the following data is lost:
• Application-specific parameter sets in the bar code scanner that were only saved tem-
porarily in the device
• The last reading result of the bar code scanner
• Daily operating hours counter of the bar code scanner
2.4.2 Switching the bar code scanner back on
Switch the power supply to the bar code scanner (the connection module) back on
- or -
Connect the 15-pole D-Sub-HD connector of the bar code scanner's connection cable
to the connection module.
The bar code scanner starts up using the most recent permanently saved configurati-
on. The daily operating hours counter is reset.
