8.1.2 Audio playback
The scanner plays back previously recorded audio data files as a scanning completion sound, using the speaker.
(1) Registering an audio data file
Up to five audio data files can be registered with the configuration software (ScannerSetting_2D).
Audio data file specifications
The table below lists the audio data file specifications supported by the scanner.
File format WAV
Audio file format PCM (Linear PCM)
Sampling rate 8 to 48 kHz (44.1, 22.05, or 11.025 kHz recommended)
Sampling size 8 bits, 16 bits
Number of channels 1 (monaural)
2 (stereo, the left channel is played)
File size 468.75 kilobytes (max.)
Notes
- Once registered, audio data files can no longer be erased, so overwrite them with new ones.
- Audio data files out of the specifications cannot be registered.
(2) Playing back an audio data file
Using the configuration software (ScannerSetting_2D) or control commands (IS and VOLSND in Appendix 2) to be
sent from the host plays back audio data files previously registered.
Notes
- During playback of an audio data file, no code can be read.
- If the playback time of an audio data file is long, take it into consideration in system operation.
- Playback specified by a control command has priority over that by the configuration software (ScannerSetting_2D).
If the scanner receives two or more playback commands, the last one takes effect.
(3) Adjusting the playback volume
You can adjust the playback volume to ten levels for each audio data file, using the QR-coded parameter menu,
configuration software (ScannerSetting_2D), or control commands.
Notes
Depending upon the playback volume selected, the speaker may make crackling or stuttering sounds due to the
installation environment.
