Sound Level Meters – User Manual
8.5.3 Threshold triggered output
An external discrete available on the 18 Pin Multi-IO socket at the bottom of the instrument can
be triggered when an audio trigger event is detected. This trigger will toggle the output from 0
to 3.3V and can be used to trigger external devices, for example a camera or noise warning sign.
The trigger output can be enabled in NoiseTools as an event when an audio trigger occurs.
The trigger output is available on the 18 pin Multi-IO Cable ZL:183 wires (black-return, brown
– trigger).
The trigger output is a TTL output. To avoid damage to the instrument do not apply any external
voltage to this signal and limit current drawn to less than 2mA.
