GLP DoP Converter DINrail

With the new DoP Converter (DMX over Powerline), GLP is offering a unique system that can transmit up to 10 DMX universes via a single power cable.

DoP can be used wherever DMX data is to be transmitted, but laying separate DMX lines is either not possible or not economical. GLP is thus providing a sensible alternative to standard wireless connections (WDMX, CRMX, etc.) that are sometimes susceptible to interference when each requires transmitter and receiver, and can be subject to severe limitations of the locally-available radio network.

GLP’s DoP is therefore particularly suitable for integration into existing infrastructure within the entire architectural lighting sector, especially in historic buildings, with existing power rail systems (e.g. museums, galleries, hotels, restaurants and retail) as well as in the lighting of public spaces.

With the new GLP DoP Converter, DMX signals can be sent over the existing power line or an existing power rail system without having to lay an additional data line or double-occupy an existing data line. With this technology, the DMX signal is modulated onto existing power lines and immediately evaluated by the fixture. It is irrelevant whether the devices to be controlled are in direct line of sight or behind thick concrete walls. To feed in and output the DMX signal, the DoP converter only needs to be connected to the same power line as the lights to be controlled and connected to the DMX controller.

If the GLP DoP Converter is set to TX mode (transmitter mode), it modulates the 512 DMX channels of a DMX universe onto the connected power line. In RX mode (receiver mode) it converts the modulated DMX universe back from the connected power line and offers 24, 128 or 512 DMX channels at one of the three DMX outputs. By simply coupling the DoP converter, up to 10 universes can be sent over a power line and decoupled at any point.

GLP DoP Converter DINRail has been specially developed for installation in new set-ups or retrofitted in existing control cabinets. The standardized housing enables quick installation on any 35mm DIN-35 rail, in accordance with EN 50222.

There are three different license models available. While all three license versions allow the DMX-to-DoP conversion (TX) of a full 512 DMX channels, the reconversion from DoP to DMX is divided into three license levels:

• The RX024 version enables conversion of up to 24 DMX channels
• The RX128 version of up to 128 DMX channels
• The RX512 version of up to 512 DMX channels

The GLP installation FR1 TM DoP, a moving head directly compatible with the new DoP technology, is already available for operation on a power rail.
