Features & configuration.
Parking installers and system integrators planning bay detection, controllers and vacancy displays.
Plan the controller groups
Identify the floors or zones that will share a network. We can review whether the proposed layout needs a node layer between its field devices and central control.
An optional aggregation layer
The node controller groups zone controllers in larger layouts. A node layer is selected for the approved network topology and is not required in every installation.
Transfer data in both directions
Bay status moves towards the central controller, while guidance data returns to the field network. Keep zone assignments consistent across both directions.
How it fits your project.
Shared system documentation covers several models. The values on this page refer to the named device; network distances depend on compliant cabling and the approved topology.
- Detect the bay status
- Collect data by zone
- Process the parking counts
- Update signs and the parking map

Applications.
Match the equipment to the site, the users and the access workflow.
Indoor parking bays
Mark the bays, mounting height and obstructions on the plan. Verify occupied and empty conditions after addressing the sensors.
Indoor parking guidance system illustration; sensor, controller and display configurations vary.Multi-floor car parks
Define the floors, zones and cable routes before selecting controller groups. Match signs to the approved network structure.
Project planning exampleAisles and entrance signs
Place signs before driver decision points. Associate each arrow or displayed count with the correct zone.

Questions about selection, integration and installation.
What is the SXK-K02N Node Controller used for?+
The SXK-K02N sits between groups of zone controllers and the central controller in larger layouts. It passes bay status upstream and guidance data back to the field network.
How many devices are needed?+
Quantities depend on bay count, field devices, cable routes and controller topology. Send the floor plan and proposed sign positions for review.
Can we add another floor or zone?+
Review the downstream device counts, cabling and controller structure before expansion. The optional node layer is selected for the approved layout.
What is checked during commissioning?+
Assign device addresses, map sensors to bays and signs to zones. Verify occupied and vacant conditions, displayed counts and communication recovery.
What should I confirm before ordering SXK-K02N?+
Identify the floors or zones that will share a network. We can review whether the proposed layout needs a node layer between its field devices and central control.
How can you help with installation?+
We provide remote video technical guidance, installation videos, wiring diagrams and installation instructions. For large projects, an engineer can provide on-site technical guidance.
