OM4000

2.5.2 Triggered Mode

With this operating mode the oscillating mirror movement is stopped after the reading

phase OFF signal (EXT TRIG becomes inactive) plus a fixed 5.3-second timeout. In

low-throughput applications or applications with scheduled operating cycles, it is

possible to extend the life of the oscillating mirror by limiting operation and therefore

mechanical wear, to the specific time that barcodes are present in the reading area.

The mirror begins movement again at the reading phase ON signal (EXT TRIG

becomes active).

The EXT TRIG+ and EXT TRIG- inputs must be connected as well as the power VS

and GND.

To use the OM4000 in this mode:

1. Set the MODE switch to Triggered.

2. Set the Frequency switch to 0 (setup). The mirror will toggle between the Min

and Max positions aiding the configuration.

3. Set the Max Position switch to the correct value for your application.

4. Set the Min Position switch to the correct value for your application.

5. Set the Frequency switch to the desired value for your application between 1-F

(triggered mode).
