Installing the MR -8
The MRX-8 Advanced Network System Controller can be installed almost anywhere in
the home.
Once physically installed it requires programming by a certified URC integrator in
order to operate local equipment using IP (Network) RS-232 (Serial) IR (Infrared) or
relays. All cables must be connected to their respective ports at the rear of the device.
Network Installation
1. Connect an Ethernet cable (RJ45) to the rear of the MRX-8 and the onto
an available LAN port of the network’s local router (Luxul preferred).
2. A certied URC integrator is required for this step congure the MRX-8 to
a DHCP/MAC reservation within the local router.

Connecting IR Emitters
IR emitters are used to communicate to AV devices such as cable boxes televisions
blu-ray players and more.
1. Plug IR emitters (six (6) supplied in the box) into any of the six (6) IR outputs
available on the rear of the MRX-8.
All IR outputs include an adjustable sensitivity dial. Turn this dial to the right
to increase the gain and to the left to decrease it.
2. Remove the adhesive covering from the emitter and place it over the IR
receiver of the 3rd party device (cable box television etc.).

Connecting RS-232 (Serial)
The MRX-8 can operate equipment via RS-232 communication. The allows discrete
serial commands to be triggered from the Total Control system.
Connect RS-232 device using URC’s proprietary RS-232 cables. These use either
male or female DB-9 connections with standard pin-outs.
1. Connect the 3.5mm into the RS-232 Output available on the MRX-8.
2. Connect the Serial connection onto the available port on the 3rd party
device such as AVRs Televisions Matrix Switchers and other devices.
