Casambi Control for 48V Magnetic Track Lighting
Wireless Casambi control over Topsund’s M20 four-wire DALI-2 lighting platform. Topsund’s current Casambi solution uses DALI-2 luminaires connected through a compatible Casambi-to-DALI controller. Casambi provides the wireless user-control layer, while DALI-2 remains the professional lighting-control layer inside the M20 system. Suitable for architectural lighting projects requiring dimming, Tunable White, scenes, wall control and flexible wireless operation.
SYSTEM ARCHITECTURE
How Topsund’s Casambi + DALI-2 Architecture Works
Topsund does not use a Casambi driver inside every magnetic track luminaire. Instead, Casambi is connected to the DALI-2 lighting layer through a compatible Casambi-to-DALI controller.

THREE DISTINCT ROLES
Casambi — Wireless control, user interface and scene operation.
DALI-2 — Professional control of the selected magnetic track luminaires.
M20 Four-Wire Track — Carries both 48V DC power and the DALI bus to the luminaires.
DOES EVERY LUMINAIRE NEED A CASAMBI DRIVER?
No.
In Topsund’s current Casambi architecture, the luminaires remain DALI-2 luminaires. The Casambi-to-DALI controller connects the Casambi wireless network to the DALI lighting layer, so an individual Casambi driver is not required inside every luminaire.
POWER & DALI BUS ARCHITECTURE
48V Power and DALI Control Are Separate Paths
The M20 four-wire track carries both lighting power and DALI control, but these remain electrically separate functions.
TWO SEPARATE ELECTRICAL PATHS
48V POWER PATH
AC Mains → SD-10048 → 48V DC → M20 Power Conductors → Luminaires
Two conductors inside the M20 track carry 48V DC power. The SD-10048 provides the low-voltage power required by the magnetic track lighting system.
DALI CONTROL PATH
Casambi Wireless Network → Casambi-to-DALI Controller → DALI Bus → M20 DALI Conductors → DALI-2 Luminaire Drivers
The other two conductors inside the M20 track carry the DALI bus.
M20 FOUR-WIRE TRACK
2 conductors = 48V DC power • 2 conductors = DALI bus
POWER & BUS FACTS
01 — SD-10048
Provides the 48V DC power required by the M20 magnetic track lighting system.
02 — DALI Signal Connection
The DALI signal connection associated with the SD-10048 provides the DALI bus connection / pass-through to the DALI conductors inside the M20 track.
03 — DALI Bus Power
The SD-10048 does not generate DALI bus power. DALI bus power must be provided by the selected control architecture.
04 — Separate Electrical Functions
48V power and DALI control share the four-wire M20 platform, but they remain electrically separate functions.
SYSTEM PLANNING PRINCIPLE
The 48V power architecture and the DALI bus-power architecture must be confirmed together before the control system is selected.
CASAMBI CONTROL & DALI-2
DALI-2 Lighting with Casambi Wireless Control
The luminaire side of Topsund’s current M20 Casambi solution remains DALI-2. The selected luminaire and driver configuration must be specified according to the project.
CONTROL OVERVIEW
01 — DALI-2 Lighting Layer Luminaire Layer
The selected M20 luminaires remain DALI-2 on the lighting side.
02 — DALI-2 DT6
For fixed-white luminaires requiring professional dimming and control.
03 — DALI-2 DT8 Tc
For Tunable White luminaires requiring brightness and colour-temperature control.
04 — Casambi App
Provides the wireless user-control interface when supported by the selected control devices.
05 — Casambi Wall Control
Compatible physical wall controls can be incorporated into the Casambi network.
CONTROL CAPABILITIES
01 — DALI-2 Lighting Layer
CURRENT TOPSUND CASAMBI ARCHITECTURE
The luminaire side remains DALI-2. Casambi operates at the wireless system-control layer through a compatible Casambi-to-DALI controller.
02 — DALI-2 DT6
DT6 is used for fixed-white luminaires requiring professional dimming and control.
03 — DALI-2 DT8 Tunable White
DT8 Tc is used when both brightness and colour temperature need to be controlled. Topsund Tunable White magnetic track luminaires are available from 2700K–6000K. The selected Casambi-to-DALI controller must support DALI DT8 Tc.
04 — Casambi App & Wall Control
Compatible Casambi controls can provide wireless operation through the Casambi App and physical wall controls. Exact available functions depend on the selected controller and DALI architecture.
A — Casambi App
Typical functions may include dimming, Tunable White adjustment, Casambi scenes and lighting-area control.
B — Wall Control
Compatible Casambi wall controls can provide frequently used lighting functions without relying only on a mobile device.
05 — Individual Control & DALI Groups
Individual luminaire control should not be assumed for every Casambi-to-DALI controller. Some converter architectures operate in broadcast mode. If the project requires individual DALI addressing or defined DALI groups, the controller must be selected specifically for that control strategy.
CONTROL PRINCIPLE
The selected luminaire, DALI device type and Casambi-to-DALI controller must be specified together. Control functions should never be assumed from the M20 track alone.
CONTROLLER SELECTION & COMMISSIONING
Selecting the Casambi-to-DALI Control Layer
The Casambi-to-DALI controller is the interface between the Casambi wireless network and the DALI-2 lighting system. It should be selected according to the project requirements rather than by protocol name alone.
01
Project Review
Select the controller for the required DALI configuration: DT6 fixed-white or DT8 Tc Tunable White.
02
System Configuration
Confirm whether the project requires broadcast control, defined DALI groups or individual DALI addressing.
03
DALI Bus Power
Some controllers include an integrated DALI bus power supply, while other architectures require a separate DALI bus power supply.
04
Technical Confirmation
There is no universal Casambi-to-DALI controller limit. Capacity depends on the selected controller, available DALI bus power, number of connected DALI control gears, required control strategy and project topology.
CASAMBI USER CONTROLS
Define the User Interface Before Controller Selection
App control, wall switches and required user functions should be defined before controller selection. The selected control layer must match the required dimming, Tunable White, scene and user-interface behaviour.
ON-SITE COMMISSIONING
Commission the Selected Control Strategy
Depending on the selected architecture, commissioning may include Casambi network configuration, controller setup, configuration for the selected DT6 or DT8 lighting system, DALI addressing or grouping where required and supported, Casambi scenes, wall-control functions, Tunable White behaviour and final system testing.
PROJECT APPLICATIONS
Where Casambi + DALI-2 Works Best
Casambi + DALI-2 is particularly useful when a project requires professional DALI lighting together with a flexible wireless user-control layer.
PROJECT PLANNING
What Should Be Confirmed Before Quotation?
A Casambi magnetic track quotation should define the lighting, power and control architecture together. Please provide the following information where available.
01

04
48V Power Load
Confirm the total connected luminaire wattage and the planned SD-10048 power-supply arrangement.
05
DALI Control Strategy
Confirm whether the project requires broadcast control, defined DALI groups or individual luminaire addressing.
06
Casambi User Controls
Confirm whether the project requires Casambi App control, wall controls, scenes or Tunable White adjustment.
07
Controller Requirements
The DALI bus-power architecture and controller capacity are selected according to the number of DALI control gears and the required control strategy.
08
Commissioning Responsibility
Confirm whether commissioning will be carried out by the local integrator, contractor or other project partner, and what level of control-system support is required from Topsund.
