These are labeled as MISC signals on the neoVIconnector These pins can be used for controlling or monitoring external devices. ### Basic Setup The MISC IO are setup in the neoVI 3G Explorer. Figure 1 shows the input output configuration. This is done by selecting Initial Values under MISC IO from the tree. On the panel shown, you can setup the direction, type, and initial state of each IOpin. The outputs are capable of LED drive through a current limiting resistor. The maximum current of all outputs should not exceed 5 mA. For protection, each IO pin has a series 47 ohm resistor and a transient protection device. ### Analog Inputs MISC pins 3 through 6 can be setup as analog inputs. To enable an analog input, you can select "Analog inputs" from the "Initial Setup" window. ### General IO Reporting You can setup the general IO to be automatically reported to the host in neoVI 3G Explorer (figure 2) You can setup the general IO to be reported at an interval or based on digital inputs changing (figure 2 : bubble 1). The report will be sent to the host as a neoVI Device Virtual Network message. When reporting based on interval is selected you can select the interval from the drop down box shown in bubble 2 in figure 2. You can select an interval from 1 to 125 ms. If you selected a report based on digital change, you can select both an interval the inputs are tested (figure 2 : bubble 2) and which digital inputs to test (figure 2 : bubble 3). You can select as many as are listed. ![Figure 1 - neoVI MISC pins can be setup asdigital outputs, digital inputs or analog inputs.](https://2396693198-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FlRJv2XDCMeZSU0VbeZlG%2Fuploads%2Fgit-blob-d88c3208309408566dfc1410a9c16c9d0cb25b99%2FFireneoIOSetup.gif?alt=media) ![Figure 2 - You can have the neoVI device automatically report the state of MISC IO pins.](https://2396693198-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FlRJv2XDCMeZSU0VbeZlG%2Fuploads%2Fgit-blob-ca76ae344f9f44bfea5db2c99aa335fa92bf6f9d%2FFireneoIORpt.gif?alt=media) --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.intrepidcs.com/vspy-3-documentation/3.9.15/vehicle-network-interface-hardware/vehicle-network-interface-hardware-neovi-fire/general-purpose-io.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
