Ekinex EK-BK1-TP Quick Start Manual

Gateway DMX – KNX TP
Code: EK-BK1-TP
KNX device with gateway function (protocol conversion)
between a serial RS485 network (Master function) with
DMX protocol and a KNX TP network over a twisted
pair communicaton cable.
integration of DMX devices over a RS485 serial network
in a KNX-based automation system for homes and
buildings.

Description

The DMX ekinex® EK-BK1-TP
apparecchio KNX modulare per montaggio a quadro. is
a KNX modular unit for panel mounting. It allows you to
exchange informations with one or more slave devices
over a RS485 differential serial network through DMX
protocol. The ekinex gateway acts as DMX master. The
informations exchanged over the DMX network are
updated over the KNX network by means of a twisted
pair (TP) communication cable.
The device manges a one-way data stream: up to 12
bytes of KNX data are defined, each one associated
with a device over the DMX network. The gateway
converts the data coming from KNX master and writes
its value on the corresponding DMX device.
Configuration is performed through a PC application
software which communicates through the integrated
Ethernet port. The application software CGEKBK1TP is
available for download at www.ekinex.com.
