Description

The DMX ekinex® EK-BK1-TP gateway è un
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

• Yellow LED (10) – KNX communication. Normal
mode: blinks when a frame is received. Boot mode:
if fast blinking: no configuration, if very slow blinking
(~0,5 Hz): loading configuration.

• Yellow LED (11) – Device error. Normal mode: ON=
at least one DMX request did not get a correct
answer; OFF=

no error. Boot mode: if fast blinking:

no configuration, if very slow blinking (~0,5 Hz):
loading configuration.

• Green LED (7) – Ethernet port. Normal mode: ON=
Ethernet connector plugged; OFF= Ethernet
connector unplugged. Boot mode: ON=

Ethernet

connector plugged; OFF= Ethernet connector
unplugged.

• Red LED (3) – KNX programming. Normal mode:

physical address programming mode on;

ON=

physical address programming mode off. Boot

OFF=
mode: if fast blinking: no configuration, if very slow
blinking (~0,5 Hz): loading configuration.

Installation

The device has IP20 protection degree and is therefore
suitable for dry indoor environments. The case is
suitable for mouting on a DIN rail (according to EN

60715) inside eletrical distribution cabinets. The proper

installation involves the bus terminal blocks to be in the
lower side.
For installation proceed as follows:

• with the aid of a tool bring the locking device in
completely lowered position (1);

• place the device on the upper edge of the DIN rail
(2);

• rotate the device towards the DIN rail (3);

• push the locking device up untili il stops (4).

Command elements

• Pushbutton that switches between normal mode
and KNX physical address programming.

1-way microswitches

• A - OFF: normal mode active. ON: Boot mode active

• B - OFF: open. ON: RS485 line termination inserted
(120 Ω termination resistance in parallel between
RT+ and RT-)

Display elements
The device can run according to two operating modes:
Normal mode (configuration loaded, Modbus and KNX
communication running) and Boot mode (no
configuration or configuration still loading).

• Green LED (8) – Device status. Normal mode: Slow
blinking (~1 Hz). Boot mode: ON= device on; OFF=
device off.

• Yellow LED (9) – DMX communication. Normal
mode: blinks when a frame is received on the
RS485 port. Boot mode: if fast blinking: no
configuration, if very slow blinking (~0,5 Hz): loading
configuration.

To unmount the device, make sure to unplug the
network connection and the bus terminal from its
housing.

Use a screwdriver to slide down the lock and

remove the device from the rail.
