Important!
In case of DC power supply, DO NOT
reverse the terminal blocks polarity!
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 con (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
cond foil shi shielding mesh;
• Belden code 82842. 2x 24AWG twisted pairs of
cond foil shi shielding mesh;
• Tasker code C521. 1x 24AWG twisted wire pair +
foil shi shielding mesh;
• Tasker code C522. 2x 24AWG twisted pairs of
cond foil shi shielding mesh.
Configuration and commissioning
Configuration and commissioning of the ekinex®
gateway must be performed using the application
program CGEKBK1TP, available for download at
www.ekinex.com.
System requirements for configuration software
• Desktop o laptop PC with Ethernet IEEE 802.3 port.
• 32/64 bit operating system, Microsoft Windows® XP,
7, 8.0, 8.1 e 10.
Note.
.NET Framework 4.0 system library installation
is required.
The ekinex® configuration software CGEKBK1TP
allows you to perform the following operations:
• Selection of physical address of the device over the
KNX TP network;
• Selection of Ethernet parameters (for configuration
download only);
• KNX network: communication objects definition and
relative group addresses to be acquired;
communication objects definition and relative group
addresses to be sent over the KNX network;
• DMX network: default values definition;
• Firmware and/or configuration update.
