<- tb5:scripts|Scripts ^ tb5:start|Toolbox5 Software ^ tb5:tft_views|TFT Views - Overview -> ====== GPOs ====== With GPOs you can output external control signals from all available internal logic sources. To assign logic sources to GPOs, in the project tree, select ''/Logic/GPOs''. For each GPO, the logic signal can be inverted or output as pulse. GPOs are available on the plugs of all audio modules or alternatively as separate module. The GPOs are totally independent from the audio signals or GPIs on the same connector. The GPOs are galvanically isolated. **Warning**\\ When connecting external devices please mind the specification of the maximum current and the maximum voltage to avoid risks and damages! [{{ gpos.zoom60.png?nolink |//General Purpose Outputs (GPO), Connecting GPOs and logic sources.//}}] In the ''GPO Assign'' list all GPOs are listed that are available in the device after inserting the corresponding modules under'' DSP-Frame I/O''. There you can assign the names for the separate GPOs. (See also [[tb5:dsp_frame_io#configuring_the_gpio_ports|Configuring the GPIO Ports]]) To assign a logic source to a GPO follow these steps: - Select the desired entry in the ''GPO Assign'' list. - Click ''Select'' to open the ''Logic Sources'' window. You can also double-click on the entry in the list. - In the ''Logic Sources'' window, select the desired logic source. - In the ''is'' area, select one of the options and define how the GPO work (see following table). - To assign the logic source to the GPO, click'' Assign''. Alternatively, you can double-click on the logic source or drag it directly to the desired GPO. If you want to disable an already defined GPO as a logic source, select the entry'' none'', which is shown on top of the ''Logic Sources'' window. The following table lists the options for the GPO behavior, which are available in the ''Logic Sources'' window: |ON | {{hi.gif?16x16}} | • The logic source works directly. | |OFF | {{lo.gif?16x16}} | • The logic source is inverted. | |Pulse on activate | {{rising.gif?16x16}} | • The rising edge of the logic source creates a pulse of 150ms.\\ • Application, for example for start pulse. | |Pulse on deactivate | {{falling.gif?16x16}} | • The falling edge of the logic source creates a pulse of 150ms.\\ • Application for stop pulse. | The currently configured characteristics are shown in the ''GPO Assign'' list as a symbol at the beginning of a line for each logic source.
