First, as briefly mentioned in the previous section of this tutorial, you have the Output Message/Signal Selection, the area where a message or signal can be selected for output. Remember this is only an option if the 'Map' action is selected for the input message or signal. Beneath this is the 'Protocol' drop down menu. This menu is only accessible when gatewaying an entire network, and allows the user to change the protocol of incoming messages to a different protocol, selectable between CAN, CAN FD with BRS, and CAN FD without BRS. ### Output Triggers ![Figure 2](https://2396693198-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FlRJv2XDCMeZSU0VbeZlG%2Fuploads%2Fgit-blob-e24a39695b342d3e02311972a284ea9a64964284%2FGWBImage11.gif?alt=media) Unique to the Output Setup are the options for an output trigger. There are four options to trigger the transmission of a gatewayed message, Recieve, Condition, Change, and Rate. The Recieve option is selected by default and is the most basic option of the four; when the specified input message is received, it will be gatewayed. Next, the Condition option allows a condition to trigger the output message. For example, a message could be triggered to output only when its input message has been transmitted 10 times. The condition is set using the rules and logic of the Expression Editor. The 'Change' trigger simply outputs the message when the input messages data changes, and, finally, the 'Rate' trigger will output a message at either the rate of the input message, or at a specified rate. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

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/application-notes/application-note-gateway-builder-tutorial/tutorial-gateway-builder-part-5-output-messages-signals-and-triggers.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.
