[Tweet](https://twitter.com/share) ### It's easy to access wiring diagrams directly through the *groov* Manage home page on *groov* EPIC or RIO. Have you ever been wiring up one of the I/O modules on your *groov* EPIC and you can't remember which port that wire goes into? Good news....you can quickly find the answer by viewing the wiring diagram through your browser or the *groov* EPIC processor's touchscreen. Here are some scenarios where you can use [*groov* Manage](https://www.opto22.com/products/groov-epic-system/groov-epic-software/groov-manage) to see some handy specs and wiring diagrams. ![Ben-w-Phone (002)](https://blog.opto22.com/hs-fs/hubfs/Ben-w-Phone%20(002).png?width=500&name=Ben-w-Phone%20(002).png) You are at your desk, making a change to your automation application. Maybe you're adding a new device and wondering if a module already mounted on your [*groov* EPIC](https://www.opto22.com/products/groov-epic-system) could handle the new device's signal type. Just log into *groov* Manage and: 1. From the Home page, click I/O. 2. Select the module you're checking, then click Info. In the Info tab: - Click Specs to see the module's supported signals. - Click Wiring for the field wiring diagram. **You are on site,** diagnosing an issue with a signal coming through a *groov* I/O module. You want to double-check that it was wired correctly. You can view the wiring diagram right through *groov* EPIC's touchscreen: from the Home page, tap I/O. Tap the module you are checking, then tap Info. The wiring diagram is the first thing shown to you.   You are off site with your machine/equipment vendor, discussing an upgrade to your existing equipment. You are wondering if the [*groov* RIO](https://www.opto22.com/products/groov-rio) monitoring the current equipment can handle the upgrades being discussed. Because you have a secure VPN connection to your *groov* RIO, you can log in to: - View your current I/O configuration: From the *groov* Manage Home page, click I/O Channels. In the Channels tab, *groov* Manage displays the list of channels, both currently configured and potentially available. - Find spec information to help you and your vendor match up signal types: From the *groov* Manage Home page, click I/O Channels, then Info. Click Specs to view all the spec information for supported signal types. **You are brainstorming on a new project** and you want to know whether an existing *groov* EPIC I/O unit has room for more modules and what other modules you may need to purchase to support some new devices. From the *groov* Manage Home page: - To identify how many slots are available on the chassis: Click I/O. The I/O page shows you any empty slots. - To review specs and wiring diagrams for all *groov* I/O modules sold by Opto 22: Click Info and Help, then Documentation. Scroll through the list of data sheets and click the one that lists modules you may need for your new project. Hope you can put these helpful hints to use right away!
