DDNG485 Serial Gateway

The DDNG485 is an RS-485 gateway/bridge that can separate DyNet network segments or integrate the Dynalite control system with third-party DMX512 and other RS-485 based systems.

Bridges and gateways incorporate a processor and two network ports with isolated communications between them. RS-485 networks continue to remain popular as they provide both power and data while remaining isolated from the user’s IP network. Common applications include:

  • Scalability - Bridging functionality between Port 1 and Port 2 creates an extendable trunk-and-spur topology with a shared high-speed backbone (trunk) optically coupled to lower-speed subnetworks (spurs). The device provides inbuilt address translation, routing, and message filtering between network segments.

  • Distance - The DDNG485 can act as a repeater to extend and isolate the control system, linking segments up to 800m apart.

  • RS-485 integration - The DDNG485 communicates with third-party RS-485 based systems configured to send and/or receive DyNet1 packets.

  • DMX512 translation - DMX512 is a control protocol primarily used for lighting and effects in the entertainment industry. The DDNG485 can be factory-set to act as a gateway between DyNet and DMX, either receiving (DMX Rx) or transmitting (DMX Tx) with full 512-channel addressing support in either mode.

  • Modbus power meters - See Modbus Power Meters.

When configured as a DMX512 gateway, SB and Dynalite devices must be connected to Port 1 and the DMX system to Port 2.
While the DDNG485 supports DIN rail or wall mounting, it does not necessarily need to be installed into an electrical enclosure, as it is solely a SELV device powered from the control network.
