TOTAL CONTROL MRX-8 SYSTEM CONTROLLER
Introduction
Congratulations on purchasing the Total Control MRX-8 System
Controller for automation and control. Using the Total Control line
of interfaces provides you full access and control for every
compatible device using IR, IP, RS-232, and Relays. This network
based control is also compatible with URC sensors, like audio
sensor and video sensor, which detects the status of a device and
provides automation triggers.
The MRX-8 makes it easy to turn on multiple devices at once such
as a TV and Blu-Ray, even lights with one button press. Enjoy
controlling your space!
Features and Benefits

compatible with MRX-8)
Can be programmed offsite via the internet, after initial
programming is completed onsite, and project is registered
with URC's Offsite Programming portal.
