User Interface (UI)
RS485 Link Wiring
An RS485 user interface (UI) link connection, wall jack, and network interface box are required if the
processor panels are not connected via Ethernet. Follow the diagram below for wiring the UI link. The
network interface and eLumen manager will be wired and configured at commissioning time by Lutron
Services personnel.

Notes
• Leave terminal 2 (PWR) of the processor's UI
link unconnected
• One UI link connection is required for each
processor; multiple processors cannot be
connected to the same UI link

• Wiring the UI link via RS485 is not necessary if
the processor is connected via Ethernet (See
Ethernet Wiring Options for details)
• See RS485 Wiring Overview for approved cable
options and additional information when using
the RS485 wiring method
