Overview:

This will cover the hardware control ports, or GPIO, on the Soundweb OMNI devices.

Hardware Configuration:

In the SYSTEM view, I've got a Soundweb OMNI device loaded. On the device object, are the GPIO nodes, with inputs on the left and outputs on the right. Each GPIO port on the Soundweb OMNI devices can be changed between a general purpose input or output. Select the object, and you'll find the GPIO settings in the PROPERTIES pane on the right.

Use these drop-downs to change the desired connection to a general purpose input or output.

The GPIO node on the object block will change from one side to the other.

Remember that these changes must be done while the device is disconnected, and cannot be done while deployed.

Control Input Properties

In the VIRTUAL view add a General Purpose Input and Output into the workspace from the COMPONENT LIST.

Select the GPI object to view the options available in the PROPERTIES window.

The default Type is Logic Binary, which will provide an On/Off or High/Low value when a set voltage is detected on the input.

This default On Threshold and Off Threshold are indicating that the On or High output will be provided on the object output when voltage above 2.5V is detected.

An Off or Low output will be provided when below 2.5V but above 0.9V.

The other type of input is Logic Continuous, which will provide a percentage value to the output based on the incoming voltage compared to a Reference Voltage set here.

The Reference voltage can be up to 12V.

The factory panels of the GPI and GPO are similar in that they will show a meter indicating either voltage or a percentage.

This GPI is set to Logic Binary with an On threshold of 2.5V. The 5V output on the back of the Soundweb OMNI device is connected to the input through a switch. If the switch is closed, the meter will show that voltage is coming in.

In addition to the measured voltage being displayed, the active LED and output node of the object block are lit.

This GPO is set to the Logic Continuous type with the maximum output voltage at 9V.

If the input of this GPO is triggered high, then the meter will show the 12V output at 100% since this is simply a binary logic source.
