Philips Dynalite DDNG485 RS-485/DMX512 Gateway

The Philips Dynalite DDNG485 is a flexible network communications bridge designed for RS-485 networks. The two opto-isolated RS-485 ports enable the DDNG485 to implement a trunk and spur topology on large project sites, with the bridge providing a high-speed backbone opto-coupled to many lower speed spurs.

  • Route DyNet to third-party systems – Such as audio-visual, Somfy blind controllers, Modbus meters and building automation systems, providing an integrated approach to total building control and energy management.
  • DMX512 mode – Transmit or receive up to 64 channels of DMX512, with automatic DyNet conversion and task triggering. Provides temporary control of house lights from the DMX512 console in an auditorium scenario.
  • Electrical fault isolation – Faults can be isolated to individual network spurs.
  • Internal controls – Programmable logic controller capable of comprehensive conditional and sequential logic and arithmetic function processing, packet filtering and DyNet to DyNet 2 translation.

Installation Instructions


The DDNG485 is one of those Dynalite products that has multiple uses depending on the project and application.

RS-485 Gateway
On larger projects the gateway is used as a RS485 network bridge for trunk and spur systems, enabling the Dynalite system to be greatly expanded.

DMX Gateway
The device is also designed to enable cost-effective integration between the Philips Dynalite control system and third-party devices. The DDNG485 has a DMX mode that can transmit or receive up to 64 channels of DMX512, with automatic DyNet conversion and task triggering. This is a popular method of allowing a lighting operator temporary control of the house lights from the DMX lighting console in an auditorium scenario.

With the increased popularity of colour changing LED lights, and the ability to run shows, it has become more common to see small DMX systems in residential projects, particularly entertainment and outdoor areas. Dynalite integrates with these systems seamlessly.

Somfy Integration
As part of the Philips Somfy Alliance, the DDNG485 is capable of connecting to a range of Somfy products (specifically controllers that have RS485 connectivity) to seamlessly integrate the lighting and window coverings control under one system. In addition to being able to drive blinds and AV screens up and down, user programmable Intermediate Positions (IPs) in the Somfy system are mapped to DyNet Presets (the number available depends on the Somfy interface used) to allow the lighting and blinds to operate together for specific presets.
