2.3 Ports and Peripheries

Figure 9: biosignalsplux ports and the button.

2.3.1 Button

The button is used to turn the device on and off and to display device status’ using the

built-in LED (see 2.3.6 Button Behavior).

2.3.2 Analog Inputs

The biosignalsplux hub has 4 or 8 analog ports to connect up to 4 or 8 biosignalsplux or

party sensors to the hub (see 3 biosignalsplux Sensors for more information about the

sensors). All channels are synchronously and simultaneously acquired.

2.3.3 Reference

The reference port allows you to connect one single lead ground cable to share a common

reference point for all sensors. However, some sensors (e.g., ECG and EEG) have their own

ground/reference electrodes, which can be used instead. A common ground connection

is, for example, useful in applications that require multiple sensors that share the same

reference point (e.g. multiple EMG sensors).

Additionally, this port is used to connect the USB adapter for the fast USB data transfer

cable to download offline acquired signal from the internal memory of biosignalsplux

devices (see 6 Data Logging and 6.2.2 Download via Fast USB Data Transfer Cable).
