1. Product Description The basic function of the 01548 router is to ensure KNX IP/Ethernet devices (main line) interact with KNX TP bus devices (secondary line) . It is powered by the TP bus and does not require an external power supply . The router is designed to route traffic based on the type of installation in the bus system hierarchy and according to the filter tables incorporated for communication towards groups .

KNX TP Figure 2: Connection Scheme To start a secure configuration download, Secure Commissioning must be activated in the ETS project before . Without activation, 01548 will behave like 01547 .1 (without support of KNX Secure) . Please also read chapter “1 .6 Important Notes” before putting the device into operation .
1.5 Secure Commissioning Before the secure download of configuration setting and/or Individual Address can start, the individual Device Certificate of 01548 must have been added to the ETS project . To add it, the ETS project must be password-protected .
• When additional protection becomes necessary (for example, the subline is located outside the building), configuring 01548 from the subline can totally be switched off . • 01548 supports long telegrams with up to 240 bytes APDU length . (Devices of both product series, the MEC couplers and UIM interfaces, can process long messages e .g .
. Both communication stack and application software are downloaded . The Firmware Update procedure via IP can be executed by 01548´s web front-end, which is independent from ETS, and makes use of special messages to speed up the process . To be protected, this process makes use of a special encryption .
4. Operational Description In KNX network installations, 01548 is used as KNX IP line/area coupler to couple KNX IP and KNX TP (see also chapter 2 .2 IP (Secure) Routing) . It can be used in the com- mon way without activation of Security and in ETS projects where Security is set to active . After connecting to KNX TP, 01548 operates with its default settings . Setting a correct Individual Address is necessary .
Up to 15 areas and 225 different addresses for line couplers can be defined . For line coupler functionality in a KNX network, 01548 has to use the correct Individual Address of a line coupler (x .y .0) . For backbone coupler functionality in a KNX network, 01548 has to use the correct Individual Address of an area coupler (x .0 .0) .
Operational Description 4.4 Adding Device Certificate Every KNX Secure device uses its own Device Certificate . Entering this Device Certificate in ETS is mandatory before activating or using KNX Security functions . The Device Certificate can be found printed on a side label on the housing . Device Certificates can be entered manually and by taking a QR code webcam picture .
Individual Address in its memory . Security settings are actualized via both IA download and application download . When 01548 is the Current Interface, an application download is necessary for actualizing IP settings of 01548 .
4.5.2 IP Configuration The IP configuration of 01548 can be set in the Properties window of the ETS . To activate DHCP/AutoIP, the “Obtain an IP address automatically” option must be set . For more details and information about configuration of IP networks, please ask your local network administrator .
Operational Description When 01548 is used as ETS Current Interface and its IP address is changed by a configuration download, ETS tries to maintain the connection to the Cur- rent Interface having the previous IP address . 01548 (now containing the actualized IP address) must be selected as Current Interface again from the list of Discovered Interfaces .
Operational Description 4.6.2 Factory Reset A long press (≈ 15 sec) of the Function Button soon followed by a short press (≈ 3 sec) executes the Factory Reset . After the first press, the LED display lights like described in Table 4: LED Status Display for Factory Reset after first Function Button Press . After the second press, all parameters (incl . Individual Address) will be set to factory default .

Setting “transmit all” is intended only for testing use . Please do not use for normal operation . I f the parameter “Send confirmation on own telegrams” is set to “yes”, 01548 systematically sends an ACK on any own routed telegram . For example, since repeaters do not use filter tables, it is useful to have an ACK sent along with routed telegrams .
Figure 16: Configuring of IP (Secure) Tunneling Cannels To use IP Secure Tunneling both Secure Commissioning and Secure Tunneling must be activated in the Properties window of 01548 . Then, also the password protec- tion option for each Tunneling Channel is available .
6.2 Accessing the 01548 Web Front-end There are three ways to access the 01548 web front-end . It can be accessed via Windows explorer directly, or by a web browser . For access via web browser either the IP address or the MAC address, together with the HTTP port, have to be known . How to use IP address and MAC address with the browser´s URL bar is described in the following .
Example 2: 01548 is used with its factory default setting . This means HTTP port is 8080 and DHCP is active . The DHCP server assigned the IP address 192 .168 .1 .201 . Then, in the browser´s URL bar has to be entered “http://192 .168 .1 .201:8080/” .
. The Individual Address, the four Individual Addresses for Tunneling (additional tunneling addresses), routing multicast address, serial number of 01548 and a last- 60-minutes KNX busload diagram (web browser must support SVG graphics) are visible . The red curve shows the maximum busload on TP and the green one shows the average busload on TP .
6.5 IP Firmware Update Under the Update tab the 01548 firmware can be updated via IP i .e . the Ethernet network . The complete remote update process is described in following steps . During this process, 01548 enters its boot mode . Then LEDs 1, 2, 3 and 7 light as described in Table 5: LED Status Display for Firmware Update .

Web Front-end Step 4: When the „request update“ button appears it has to be pressed to select the update file and enter boot mode”. Figure 26: Request Update Step 5: The update file can be selected and uploaded. After that, the device exits boot mode and restarts. Clicking on the „Abort“ button cancels the firmware update procedure and the device exits boot mode.
Glossary 7. Glossary Step Manual Function An ACK is a positive IACK frame . If the sender detects an ACK, then the sender´s data has been received correctly, i .e . been successfully transmitted to the receiver . Acknowledgment on the KNX Link Layer is also called Immediate ACK (IACK) in KNX jargon, presumably to differentiate it from other ack methods on the upper layers .
• How can I reach the web front-end in case I don´t know IP address and MAC address? When 01548 cannot be accessed via the device list in the Windows network explorer (after refreshing the window), the actual IP address must be found at first . Then use Windows or the ETS like described in last question .
