Overview of the RS232 Interface

Definitions of Common Terms

Delay Time - The time a switch will wait before it goes to the desired state.
Fade Time - The time it takes a dimming device to reach its goal level.
Master Control - A RadioRA Master Control is a system control point that provides control of lights throughout a
®
home. Master Controls can be wall mounted, tabletop, or cordless. Other system Master Controls are the Switch
Closure Interface, the Infrared Interface, or another RS232 Interface.
Master Control Number - Master Control Numbers are used to identify RadioRA Master Controls via the RS232
®
Interface.
Phantom Buttons - Phantom Buttons are "virtual" buttons in the RS232 Interface. Though there are no physical
buttons that represent these Phantom Buttons, they work very similarly to buttons on RadioRA Master Controls.
®
Each Phantom Button can be assigned either as a ROOM or SCENE.
Phantom LEDs - Phantom LEDs are "virtual" LEDs in the RS232 Interface. Though there are no physical LEDs
that represent these Phantom LEDs, they work very similarly to LEDs on RadioRA Master Controls. Phantom
®
LEDs 1–15 are associated with Phantom Buttons 1–15, respectively.
ROOM Button - A ROOM button is a programmable button whose LED is ON when any lighting zone assigned to
that button is ON at any level. When issuing an "ON" command, a ROOM button may only turn zones ON, not
OFF.
SCENE Button - A SCENE button is a programmable button whose LED is ON when the SCENE associated with
that button has been activated. The LED will go out when the light zone changes level or receives a command to
change level, even if the new level is the same as its preset level. The LED will also go out if the SCENE is turned
OFF. When issuing an "ON" command, a SCENE button may turn zones ON or OFF.
Zone - A zone is any individual RadioRA Dimmer, Switch, or GRAFIK Eye Interface. A RadioRA System has a
® ® ®
maximum of 32 zones.
Zone Number - Zone Numbers can be used to identify any individual zone (one Dimmer, Switch, or GRAFIK
Eye Interface) in your RadioRA System via the RS232 Interface.
