For recording events from an external source, LabSat 3 is equipped with a digital input (DIGI) and digital output (DIGO) which can be found on the expansion connector at the rear of the device.
- Digital input is pulled up externally to 5 V.
- Digital out is a 5 V level output.
To enable the digital input for recording, go to Menu > Setup > Digital > CH1 and enable ‘Digi’ in the signal list.
- During recording, LabSat 3 will now also record the state of DIGI (pin 3 on the expansion connector).
- During replay, the DIGO pin will output the recorded DIGI signal states.
