Installation Guide
product description
The 01504.2 media coupling device can be used as a line coupler, a backbone coupler, or a line repeater. The basic functionality of the 01504.2 is coupling a KNX TP main line with a KNX TP subline. Providing galvanic isolation between the two connected lines enables a data connection between the upper line (mainline or backbone) and the lower line.
Due to its flexibility, the coupler can be used as a line coupler to connect a subline to a mainline or as a backbone coupler to connect a mainline 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 configurable 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 troubleshooting. To easily identify common communication problems due to busload 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. The result is up to four lines can form a single subline with up to three line repeaters used after the line coupler. Each sub-line segment requires its own KNX power supply unit.
KNX topology
Please note:
Commissioning at delivery status means:
- All telegrams are blocked because the filter table is not defined
- The fallback time after the manual operation is 120 min
- The physical address is 15.15.0

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

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
unction is essential. After the download, the 01504.2 automatically returns to
the “Normal Mode”.
Programming LED (7):
Off: Normal Mode
On: Program Mode
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.
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 the 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”.
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 color). 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
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 the default setting the coupler only routes those telegrams whose group
addresses have been entered in its filter table.
In case of not receiving an acknowledgment 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 connected lines. The default settings of these parameters
should be retained.

Line/Field coupler´s database entry in the ETS5.
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
address (individual address) can be changed/downloaded to the device. 
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.

Important note:
The parameter “transmit all” for Group telegrams or Physical telegrams is
intended only for testing purposes. This setting should not be used during
normal operations.

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 the transmission of a telegram according to the
physical address of a receiver the line repeater is able to repeat the
telegram. With the parameters „Physical: Repetition if errors on mainline/on
subline“ this function can be set separately for both lines. In the case of
routing a group telegram without not receiving an acknowledgment or in case of
an abused 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.
