4.1.2 Foot Switch
Figure 72: Foot switch.
This trigger device is useful to begin acquisition via Bluetooth to OpenSignals (or any
other custom software) or to manually start offline acquisitions stored in the hub’s
internal memory when no Bluetooth connection is available.
How to connect your accessory to your biosignalsplux
The foot switch needs to be connected to the digital port of your device (see 2.3.4 Digital
Port).
How to configure your foot switch in OpenSignals (r)evolution to mark events
Input devices, such as the foot switch, do not require to be configured in OpenSignals
(r)evolution if their intended use is to mark specific actions during an acquisition. In this
case, their input state can be seen in OpenSignals’ real-time acquisition mode in the
information bare located right below the acquired signals (circle to the left of INPUT
DIGITAL). The digital input circle will turn blue if a digital input has been received (foot
switch pressed) or be kept empty if no digital input has been received (foot switch not
pressed; see Figure 73).
Figure 73: Digital input states.
The received inputs will be visualized in an extra channel named IO1 in the visualization
mode.
