11 - LabSat3W Digital In/Out

Table of contents
No headers

For recording events from an external source such as an event logging switch, LabSat 3 Wideband is equipped with two digital inputs (DIGI 1 and DIGI 2) and two digital outputs (DIGO 1 and DIGO 2) which can be found on the expansion connector at the rear of the device. 


Digital inputs are pulled up externally to 5 V. The input will accept signals up to 12 V DC. Switching threshold for the digital inputs is 2.5 V. Digital out is a 5 V level output.


To enable the digital input for recording, go to Menu > Setup > Digital, select one of the four channels and then enable the tick against DIGI 1 or DIGI 2 in the signal list. Then, during recording, LabSat 3 Wideband will record the state of DIGI 1 or DIGI 2 (pin3 or pin 8 of the expansion connector). During replay, the relevant DIGO pin will output the recorded DIGI signal states.
