FOUR EDGES / DETENT
Common mechanical encoders
Bourns PEC11R, PEC12R and PEC16, Alps EC12, and CTS 288-class devices are representative matches for this setting.
CASAMBI ENABLED · QUADRATURE ENCODER INTERFACE
EncoderCas
Keep the knob the designer chose. Make it a deeply configurable Casambi control.
Connect a conventional passive quadrature encoder, its center push switch and one auxiliary dry-contact point. EncoderCas turns physical rotation into proportional Casambi level, push into intelligent on/off memory, and the extra terminal into either a mapped input or a low-current electronic contact.

EncoderCas expects passive A/B phase contacts, a passive center switch and a common Ground. Select the encoder type that matches its edges per detent.

THE KNOB FEELS SIMPLE · THE PARAMETERS DO THE WORK
Shape the physical experience
for the actual control.
Use the settings to make a compact 24-detent knob, a long-travel precision control or a fast-spinning optical encoder all reach the same Casambi level range naturally.
Choose the useful travel
Set 4–1000 detents from Minimum to Maximum. A nonzero minimum keeps downward rotation from switching fully off; the center button still commands OFF.
Match the human expectation
Clockwise-up is the default, but direction can reverse. Acceleration levels 1–4 multiply steps during fast turns without crossing the limits.
Decide what ON means
The center switch can return to Maximum, restore the last nonzero level or use a defined Fixed On Level.
ONE AUXILIARY TERMINAL · TWO POSSIBLE ROLES
Add another contact
to the control station.
The released fixture profile determines whether X2-4 appears as a PushButton input or a low-current output channel. Both roles share X2-5 Ground.

Signal interface only: the 25 mA published installation rating is for a compatible contact-sense input. Never drive a relay coil, lamp, motor, solenoid or other load.
Match a maintained auxiliary switch or a momentary designer button.
Add dimming and endpoint gestures without another rotary control.
Share absolute level and dim direction with compatible powered NED stations.
Close or release a compatible low-current input from a Casambi command.
TWO GANG-CAPABLE CONTROL SOURCES
The encoder and auxiliary input
can synchronize separately.
Encoder Action has its own Gang setting, and Dry Input Action has another. Matching compatible NED controls exchange absolute level and direction so every station responds correctly on the first operation.
