About the FONTUS #
What is FONTUS? #
FONTUS is a versatile 485 control interface that can be used in two key ways:
To transmit power and data over two-conductor wire
As a standalone 485 motor controller
What Can FONTUS Do? #
FONTUS receives commands from third-party systems (such as control systems, projectors, or keypads) and translates them into 485 commands for controlling Screen Innovations motorized products.
Supported Input Types:
12V Trigger (latched, 7-12V)
Contact Closure (relay or dry contact)
Infrared (IR)
FONTUS Keypad
Compatible Products #
FONTUS can control nearly all 485 motorized products from Screen Innovations, including:
3/5 Motorized Screens
Solo 2 / Solo Pro 2
Nano Shades
Zen Shades
Veil
Powering FONTUS #
FONTUS is an actively powered device, requiring 7-28V DC regardless of application.
Power Options: #
Janus Power System
Included 24V Wall Adapter (in FONTUS kits)
Third-party 24V DC power supplies
Application Notes: #
Line Voltage Setup:
The 24V power supply powers FONTUS only.
The motor is powered separately via line voltage.
Low Voltage Setup:
The 24V power supply powers both FONTUS and the motor.

Changing your FONTUS from White to Black #
Remove the 485 connector.
Locate the SI Rip cord hidden under the terminal block.
Find a small cut in the heat shrink near the bottom right corner, beneath the terminal block.
Position the SI Rip cord in the cut. While holding the codec firmly, slowly pull the Rip cord toward the BCP side to begin tearing the white heat shrink.
Peel away the remaining white heat shrink, exposing the black layer underneath.
