1 Overview
1.1 Product introduction
The MG0601 coupler is a modular installation device that combines the functions of a KNX line coupler and a
KNX line repeater. When used as a line coupler, it connects main lines and trunk lines or regional lines. As a line
repeater, it can connect more than 64 devices on a bus. Electrical isolation is provided in this way.
The coupler sends physical addresses, group addresses and broadcast messages by path. The physical address
message is sent according to the path, and the coupler compares the target physical address with its own
physical address. Automatic filtering determines whether the corresponding physical address packets are
passed. The packets follow the path or not according to the path depending on the parameter configuration. If
the coupler has not received the project-assigned physical address, this may result in the device not being able
to communicate during commissioning. The coupler provides a filter table, all group messages present in the
filter table will be routed, otherwise they will be blocked, thereby reducing the bus load. The filter table is
automatically generated by the ETS software tool according to the commissioning system. It is useful to
configure filter group addresses in the filter table, especially during debugging and diagnostics. In the group
address, the main group address is 0....13 can configure filtering and other parameters. The main group
addresses of group packets 14....31. do not do any isolation configuration. If the coupler sends the message
along the path without receiving an acknowledgment or transmission error, repeat the message up to 3 times.
At the same time, in order to prevent false repetition of group messages, the two lines of the response are set
separately. In the standard setting this parameter can be set separately.

1.2 Topology
1.2.1 Line coupler
As a line coupler, the MG0601 connects a branch line to a main line, each line requiring it to have its own power
supply. Line couplers play the role of filtering messages and reducing bus load. When used as a line coupler, its
physical address is X.Y.0 (X = 0~15, Y = 0~15), that is, there can be up to 15 main lines, and there can be 64
devices on the main line, including line couplers, which can be relayed through linker segments (up to 3-line
repeaters) for up to 3840 devices
Figure 1.1 Line coupler topology
1.2.2 Zone coupler
As a zone coupler, the MG0601 connects a main line and a zone line, each requiring its own power supply. The
regional coupler plays the role of filtering the messages and reducing the bus load. When used as a regional
coupler, its physical address is X.0.0 (X = 0~15), that is, there can be up to 15 main lines, each main line can have
up to 15 branch lines, and there can be 64 devices on the branch line including lines Couplers that can connect
line segments via repeaters (up to 3-line repeaters) for up to 57,600 devices

1.2.3 Repeaters
The MG0601 acts as a repeater, connecting the data streams of the two line segments but electrically isolated. In
a line, up to three repeaters can be connected in parallel to form a line. This is how up to four line segments form
the entire branch. Thus, spur lines can be expanded from 64 devices (1 segment) to 256 devices (4 segments).
Each line segment must be powered by its own KNX power supply.
Repeaters do not have filter tables, so it does not matter whether the message is initiated within the line, or
whether it has been sent from the main line through the repeater, regardless of which segment of the line the
message was sent on. .
If there is a transmission error in the physically addressed telegram, the telegram is not repeated. If the repeater
routes the telegram and no acknowledgment is received or there is a transmission error, the repeater repeats the
telegram up to three times. Using the parameter If an error occurs repeating the group telegram, the responses
of the two line segments will be set separately.
When used as a repeater, its physical address is X.Y.Z (X = 0~15, Y = 0~15, Z=1-255). That is, branch line, up to
256 devices.
