Product description - KNX topology
1. 01504.2 product description
The 01504.2 media coupling device can be used as a line coupler, as a backbone coupler or as a line repeater. The basic functionality of the 01504.2 is coupling a KNX
TP main line with a KNX TP sub line. Providing galvanic isolation between the two connected lines it enables a data connection between the upper line (main line or
backbone) and the lower line.
Due to its flexibility the coupler can be used as a line coupler to connect a sub line to a main line or as a backbone coupler to connect a main line to a backbone line.
The main task of the 01504.2 is to filter the traffic according to the installation place in the hierarchy (individually addressed telegrams, in this document named Physical
telegrams) or according to the built in filter tables for group oriented communication (Group telegrams).
Compared to other similar products the 01504.2 provides outstanding features, for example its support of long messages (up to 240 byte APDU length) and a configu-
rable one button activation of the “Manual Function” (transmit all telegrams, transmit Physical telegrams or transmit Group telegrams).This functionality is helpful during
installation, during run time and for trouble shooting. To easily identify common communication problems due to bus load or retransmissions on both lines the high
informative 6 duo LED display shows the bus status on each line accurately.
The 01504.2 is also able to link two lines for data transfer. As a line repeater the 01504.2 still provides galvanic isolation between the connected lines. Result is up to
four lines can form a single sub line with up to three line repeaters used after the line coupler. Each sub line segment requires its own KNX power supply unit.

Operational description
4. Operational description
According either to the factory default settings or to the latest parameter settings (downloaded from ETS, also other tools) being in “Normal Mode” the 01504.2 oper-
ates as it is supposed to.
The default configurations of the “Normal Mode” are set by the main line and the sub line parameters.

Programming N.A. On: device in “Program Mode”
4.2 Program mode
With the Programming button the device can be switched between “Normal Mode” and “Program Mode”. To download the physical address to the device this
function is essential. After the download the 01504.2 automatically returns to the “Normal Mode”.
Programming LED (7):
Off: Normal Mode
On: Program Mode
4.3 Function button
The function button is used for two purposes, either to switch to “Manual Function” or to do a factory reset. Being in “Normal Mode” it depends on the duration
of time the button is being pressed.
4.3.1 Manual function
• Long press (≈ 3 sec) in “Normal Mode”
The device activates the “Manual Function” and the LEDs change their status.
Pressing the button again for some seconds deactivates the “Manual Function”.
After expiration of the Fallback time the device returns to “Normal Mode” automatically. To configure the “Manual Function” and set the Fallback time
use the parameter tab “General”.
Please note:
The latest downloaded settings (parameters) and the filter table are still available after switching back from “Manual Function” to “Normal Mode”.
4.3.2 Factory reset
• Very long press (≈ 15 s) in “Normal Mode”
A factory reset is carried out by pressing the button for about 15 seconds (LEDs 1,2,5,6 light with mixed colour). After release, pressing it again for
some seconds resets all the parameters to factory default (incl. physical address). Subsequently, the LEDs change their status.

Application description line coupler - ETS-Parameters line coupler
5. Application description line coupler
With the coupler receiving physically addressed telegrams (Physical telegrams), for example during commissioning, it compares the physical address of the receiver
with its own physical address to decide whether to route the telegrams or not. On receiving telegrams with group addresses (Group telegrams) the coupler proceeds in
accordance with its parameter settings.
At default setting the coupler only routes those telegrams whose group addresses have been entered in its filter table.
In case of not receiving an acknowledgement after routing a telegram, due to a bus transmission error for example, the coupler repeats the telegram up to three times
(depending on the corresponding parameter that is set by ETS). With the parameters „Repetitions if errors ...“ this function can be adjusted separately for both con-
nected lines. The default settings of these parameters should be retained.
6. ETS-Parameters line coupler
All screenshots in this document describing ETS parameters represent the Line/Field coupler´s database entry in the ETS5.
6.1 Settings
In the properties window the basic settings of the Line/Field coupler can be adjusted and checked. Under the Settings tab the device name and the physical ad-
dress (individual address) can be changed/downloaded to the device.
Fig. 4a: Properties/Settings Fig. 4b: Properties/Information
When not already configured as “Line coupler”, the application program for “Line coupler” has to be downloaded to the device.
Under the Information tab this configuration can be changed by the menu “Change Application Program”. After changing the configuration the filter table entries can
be added manually. Also updating the application program can be done here.

ETS-Parameters line coupler - Application description line repeater
7. Application description line repeater
Line repeaters do not use a filter table. A received telegram is routed to all lines irrespective of in which line it is processed. It is therefore not important whether the
telegram is triggered within a line or whether it is sent from an upper line to a lower line via a coupler.
When an error occurs during transmission of a telegram according to the physical address of a receiver the line repeater is able to repeat the telegram. With the param-
eters „Physical:
Repetition if errors on main line/on sub line“ this function can be set separately for both lines.
In case of routing a group telegram with not receiving an acknowledgement or in case of a bus device detecting a transmission error the line repeater repeats the
telegram three times.
With the parameters „Group: Repetition if errors on main line/on sub line“ this function can be adjusted separately for both lines.
