Epson Projector Config Tool is an app that allows you to change projector settings and check information using NFC wireless communications technology. By simply holding an NFC-compatible iPhone®* over the NFC mark on the projector, you can obtain the information and change settings even when the projector is off. You can configure all the network and projection settings before the installation, which can greatly reduce the time and effort that required to install multiple projectors. * iPhone® 7 and later Main Features 1) Read/write function via NFC tag You can read or write projector setting information simply by holding the iPhone® running this app over the NFC tag. NFC writing can be secured by setting password so that only the device administrator can change the settings. 2) Batch change function for setting up multiple projectors You can use the app to change the up to 100 projector’s settings as a batch and apply them by holding your iPhone® over the NFC tags on each projector. In addition, you can export a CSV file to edit multiple projector information using spreadsheet software and then import it into the app to change projector's settings. 3) Projector management feature You can make the routine management of projectors a breeze, using information such as operation time and error logs read by NFC tag even when they are powered off.
