DMX - KNX gateway

Code: EK-BK1-TP

Description

The Ekinex® DMX - KNX Gateway performs a protocol conversion between a serial RS485 DMX and a KNX TP network. The device works as DMX master.

The device integrates a KNX bus communication module and it is suitable for mounting on a 35 mm DIN rail; it requires an auxiliary power supply (8...24 Vac or 12...35 Vdc).

It provides seamless and reliable data exchange between DMX512 lighting control networks and building automation systems on a KNX TP bus.

Other information

DMX512 is a standard for asynchronous serial transmission of digital data between controllers, devices and accessories for the light industry, approved by ANSI (American National Standards Institute) and supported by ESTA (Entertainment Services and Technology Association).
