Accessing Rover/Comm4
Rover Overview
Rover is a service tool that allows parameters to be viewed or adjusted in UCM v 2.0 and higher.
Prior to UCM v 2.0, you would need to use EveryWare to access units that were stand alone. The
operating and programming guide for Rover is EMTX-SVX01*-EN. Rover Comm4 is a software
application for monitoring, configuring, and testing VAV II/III/IV controllers on Comm4 links. Rover
Comm4 replaces Every Ware service software.
Note: For Instructions on how to use Rover Comm4, refer to the Rover Comm4 online Help by
clicking Contents and Index on the Help menu.
