Communication and configuration
In SW67843, configure RS485 baud rate, parity and addresses, connected DALI nodes and register mapping. Use DALI Console to prepare addresses, groups and scenes and test communication with luminaires. Ethernet is used for configuration and updates.
An external Modbus RTU Master must initiate reads and writes. Independent polling of other Modbus Slave/Server devices requires a model with the opposite communication role. The base code HD67843-B2 does not specify DALI bus power. Before ordering, we will select HD67843-B2-Y with DALI bus power or HD67843-B2-N without it to match the installation. We will also check support for the functions of the specific luminaires and their control gear.
Supply and accessories
Please provide the complete order code. If you need a power supply, connection cables or help with configuration, include them in your enquiry. We will confirm the scope of supply and required accessories for your installation in the quotation.
Documentation and software
Diagrams and hardware version
The images help identify the hardware version. When replacing an older unit, compare its label, connectors and dimensions; we will confirm the version to be supplied in the quotation.
Frequently asked questions
Is knowing the two protocols enough?
The device roles, physical interfaces and data to be transferred must also be checked. An external Modbus RTU Master must initiate reads and writes. Independent polling of other Modbus Slave/Server devices requires a model with the opposite communication role. The base code HD67843-B2 does not specify DALI bus power. Before ordering, we will select HD67843-B2-Y with DALI bus power or HD67843-B2-N without it to match the installation. We will also check support for the functions of the specific luminaires and their control gear.
How is this converter configured?
In SW67843, configure RS485 baud rate, parity and addresses, connected DALI nodes and register mapping. Use DALI Console to prepare addresses, groups and scenes and test communication with luminaires. Ethernet is used for configuration and updates.
What information should I send to check the selection?
Send the exact device models at both ends, the protocols and communication roles, the number of devices and the required values. For a PLC, include the firmware and method of accessing its data.
FOXON support with selection and ordering
