1.2 Topology
1.2.1 Branch-line coupler
The MG0401 IP router can be used as a KNX branch line coupler to filter messages and reduce the load on the bus.
When used as a branch line coupler, its physical address is X.Y.0 (X = 0 ~ 15, Y = 0 ~ 7). There will no longer be any area
coupler above the current branch line.

1.2.2 Zone coupler
The MG0401 IP router can be used as a KNX zone coupler to filter messages and reduce the load on the bus. When
used as a zone coupler, its physical address is X.0.0 (X = 0 ~ 15). A standard KNX branch line coupler (with KNX buses
on both sides) can be deployed under the current area.

1.2.3 Multi-Zone Coupler
MG0401 IP router can be used as a multi-zone coupler to expand the capacity of the system. When used as a
multi-zone coupler, its physical address is 0.0.0 (X = 0 ~ 15), and the backend system uses the IP address of the IP
router to distinguish multiple independent KNX systems.

6.1 General parameter
Figure 6.1 General parameter setting
6.1.1 Device name
This parameter is a character parameter. Up to 30 English letters and symbols
This parameter is used to set a readable distinguished name for MG0401. When the client (ETS or background
software) finds the MG0401 IP router, the IP router will provide this information to the client, and the client will display
this information to help users to identify the specific IP router easily.
6.1.2 IP Address mode
This parameter is optional. Options:
（1）Auto（DHCP）
（2）Manual
This parameter is used to set how to obtain the IP address of the MG0401 IP router. MG0401 IP router supports
"Dynamic allocation" and "Manual setting" to set the local IP address.
Option Description
DHCP
Obtain IP address through dynamic allocation. When there is a DHCP server
(such as a router) in the IP-side network, the DHCP server will automatically
assign a suitable IP address to the IP router.
Manual
Set the IP address manually. After selecting this option, an additional IP
address configuration page will appear on the ETS parameter configuration
page. On this IP address configuration page you can manually set the IP
address, IP router address, and mask address.
6.1.3 Tunnel Link starting address
As shown below:

KNX/EIB BUS
KNX/IP ROUTER
Product Manual

MG0401 supports 5 links. Each link needs to be assigned a physical address. These addresses are set here as the
starting address and are automatically assigned in the order in which the links were established.
Note: The default address is relatively high, and generally does not need to be modified.
6.1.4 KNX IP Routing multicast address
This parameter is used to set the actual multicast address on the Ethernet side. The default is the KNX protocol system
multicast address 224.0.21.31. When the actual system configuration needs to divide the multicast address, you can
configure it through this.

6.5 ETS Connection management
MG0401 IP router can be used for ETS programming interface, downloading device applications, reading bus
messages, managing device information, etc.
（1）click to enter Extra ->Option ->Communication -> Configure Interfaces…
（2）Create a new connection in the ETS Connection Manager page and select the connection type as "KNXnet / IP"
（3）Click “Rescan”, all IP routers under the same network segment will be scanned. All routers will display the device
name (name of parameter configuration), IP address and MAC address.
（4）Click "OK" to return to the Communication page and click "Test". If "OK" is achieved, the connection is successful.
Note: ETS4 connection has its particularity, the connection method is as follows:
Step 1：Click Setting  Communication；
Step 2：Click New button, as shown below:

KNX/EIB BUS
KNX/IP ROUTER

Step 3：After clicking the new button, the following dialog box appears：
In the above dialog box, the entries are as follow：
Name：Enter the name of the gateway, self-naming.
Type：Select KNXnet/IP。
IP address：Enter the IP address of the selected gateway。
Port：Fill in 61118。
NAT mode：Not selected。
6.6 Multi-connection function
MG0401 IP router supports up to 5 clients to connect at the same time.
After the first client connects to the IP router, the IP router will assign a "second physical address" for accessing the bus.
This address can be set in ETS. When the second client tries to connect, the IP router will add 1 to the "second physical
address" of the first client. For example, when the address of the first client is 15.15.201, the address of the second
client is 15.15.202, the third client address is 15.15.203, the fourth client address is 15.15.204, and the fifth client
address is 15.15.205. The "second physical address" is unique within the KNX network. Repeated conflicting physical
addresses will affect normal communication
6.7 Engineering typical configuration
In engineering configuration, it is often required that the multicast data of the KNX branch line can be transmitted to
the background or remote control terminal, and it is required to perform ETS configuration to the devices of other

KNX/EIB BUS
KNX/IP ROUTER
Product Manual
14
branch lines through the gateway of one branch line. At this time, the typical configuration of the filtering rules of the
gateway is shown in the following figure:
As shown in the figure above, the KNX-> IP-side multicast packets and physical packet filtering rules are set to the
Router mode, which means that both KNX-side unicast packets and multicast are sent to the IP side, so that devices on
the IP side can receive these messages.
The IP-> KNX-side multicast packets and physical packet filtering rules are set to Filter mode, so that both unicast
packets and multicast packets that are not on this branch line are filtered out, reducing the load on the KNX branch
line.
7 Safe use and maintenance
(1) Read all instructions carefully before use。
(2) Create a good ventilation environment.
(3) During use, pay attention to moisture, shock and dust.
(4) Strictly forbid to rain, contact with other liquids or corrosive gases.
