Universal Remote Control (URS) MRX-20 - Manual (Page 34)

Installing the MRX-20
Physical Installation of the MRX-20 and Accessories
The MRX-20 Advanced Network System Controller can be installed anywhere in the home with a Cat-5 cable. Up to eight MRX-20’s can
be installed, where the first unit is the master controller and the other seven units are auxiliary controllers. Once installed it can then be
programmed to operate all local equipment using IR, RS-232, Relays or 12V Triggers. It can either be placed on top of the equipment or
rack mounted (using the optional rack-mount adapter.) It must receive power using the included power supply. All IR emitters, HDMI,
RS-232 cables and sensors are plugged into their respective ports on the back. Wires are connected to the detachable connectors for
use of the relays.
Network Installation
1. Connect an Ethernet cable (RJ45) to the rear of the MRX-20 and into the network router or switch.
2. Connect your laptop into the same network router as the MRX-20.
3. Plug flashers into any of the ten flasher ports on the rear of the MRX-20.
Locating the MAC Address
The network MAC Address is a unique number that identifies a device on a network. By listing the MAC address during programming,
URC network devices can use DHCP. The MAC address of the MRX-20 can be discovered over the network through programming. The
unit’s MAC address can be found on a label on the side of the unit (left side when facing rear).
