Field Assistant is a standalone tool you can install on your computer or laptop to access a single or multiple OEMCtrl controllers.
In Field Assistant, you can use local access to connect to a single controller or multiple controllers. You can also use IP to access an entire network of routers and controllers.
By design, Field Assistant will not work over third-party BACnet Routers. The reason an OEMCtrl router is required is to enforce the security permissions framework to protect the algorithmic intellectual property of the lighting panel manufacturer.
