Product description<br />
4.6.2 Object trigger control<br />
In order to start an object-related reading process, the bar code scanner requires an appropriate<br />
external signal (trigger source) for reporting an object in the reading area. The start<br />
signal is emitted via an external reading pulse sensor (e. g. photoelectric reflex switch) as<br />
standard. As soon as an object has passed the reading pulse sensor, a time window opens<br />
in the bar code scanner (“reading gate“) for the reading process.<br />
Alternatively, a command activates the reading process via a data interface or the CAN-SEN-<br />
SOR network. In Automatic Cycle mode, the actual bar code scanner generates the reading<br />
gate internally with an adjustable mark-space ratio.<br />
The reading pulse can be ended in a number of ways: With external triggering by the reading<br />
pulse source or a command, internally by a timer or an evaluation condition to be met.<br />
Note<br />
The trigger source can be configured using the SOPAS-ET configuration software:<br />

4.6.3 Oscillating mirror control<br />
You can manipulate the position of the scanning line for the line scanner with oscillating mirror<br />
(<strong>CLV63x</strong>-6000/<strong>CLV63x</strong>-6120) by configuring the oscillating mirror.<br />
In addition to parking (fixed scanning line position which can be adjusted) or continuous<br />
oscillation independent of the reading pulse, controlled operation of the oscillating mirror<br />
also enables optimised operation sequences related to the reading pulse:<br />
• n-fold oscillation around an adjustable start position within the reading pulse<br />
• One-shot: one-time deflection (forward and return) per reading pulse from an adjustable<br />
start position<br />
In every oscillation mode, the amplitude can be adjusted separately for each of the two deflection<br />
directions. The deflection speed ratio of one deflection direction to the other can be<br />
adjusted within the selected periodic time for the entire oscillation sequence.<br />
