Data sheet STEKBK1TP_EN
V1.02 – 11 2015
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. Ideal application in
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 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.

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 Ωtermination 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.
• 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:
ON= physical address programming mode on;
OFF= physical address programming mode off. Boot
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).

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.
Note. It is recommended to install the device so to
always guarantee full frontal accessibility, in order to
properly display the status LEDs.

KNX connection
Connection to KNX bus is made via the supplied KNX
terminal block. The terminal block must be inserted into
the slot located on the lower front side of the device.
KNX terminal block features
• Conductors’ spring clamping
• 4 conductors’ location for each polarity
• Suitable for KNX bus cables with single-wire
conductors (diameter between 0.6 and 0.8 mm)
• Recommended wire stripping: 5 mm
• Color code: red = bus conductor + (positive), black =
bus conductor – (negative)
RS485 DMX connection
In order to terminate the RS485 network and balance
the line impedance, you must enter the terminating
resistor (120 Ω), by setting ON the 1-way microswitch B.
The maximum extension of the RS485 network is 1200
m.
Below are some recommended cable codes for wiring
the RS485 line:
• Belden code 8132. 2x 28AWG twisted pairs of
conductors + foil shielding + shielding mesh;
• Belden code 82842. 2x 24AWG twisted pairs of
conductors + foil shielding + shielding mesh;
