Line Coupler, MDRC
The line coupler is used in larger installations to connect KNX lines or areas. The lines or
areas are galvanically isolated from one another. Telegrams can be filtered to simultaneously
reduce the telegram traffic between lines or areas. With ETS 4 (V4.1.2 and higher) the com-
plete group address range of the main groups 0...31 can be filtered. Within a line, the
LK/S 4.2 can also be used as a line amplifier (repeater).

IP Router Secure, MDRC
Connects the KNX bus with the Ethernet network and encrypts communication on the
IP backbone. The device uses the KNXnet/IP Secure protocol for communication (Routing
and Tunneling). It can be used as a fast line and area coupler. The full filter table for main
groups 0-31 is supported. KNX devices can be programmed via the LAN using ETS. For this
and further clients 5 Secure Tunneling Servers are available. The IP address can be fixed or
can be received from a DHCP server. Power supply via 12…30 V DC or PoE (IEEE 802.3af
class 1). The KNX Standard Communication (Multicast) can be switched off. In this case,
IPR/S 3.5.1
up to 10 IPR/S 3.5.1 can communicate using unicast communication.
