For an I/O Controller to work properly it must be paired with a reader. Once an I/O Controller is paired with a reader it will only work with that one reader. After wiring the I/O Controller and powering it on, the red power light should begin blinking red indicating it is ready to pair.

Below is a step by step guide on how to pair an I/O Controller with a reader after you have wired it with its corresponding device. You will need the Door to Cloud Mobile X app which is available on Android, and Apple iOS you can search for SekureID in your appropriate app store and select it from the list of apps. Your mobile device will need to be on the WiFi of the same network that the devices are on.
