Introduction
In R205-010:1996 was published documenting the medium interface solutions for Twisted pair
implementations of the then existing European home and building electronic systems, more specifically
Batibus and EIB.
In 1997 the convergence process between the Batibus, EIB and EHSA was initiated, which resulted in 2003
in the publication of the KNX standard and in the subsequent submission of this standard by the KNX
Association as CENELEC cooperating partner to CLC/TC 205. This resulted in a positive UAP vote of this
standard as part of the EN 50090 series by the European National Committees.
This version intends to bring the description of the HBES medium interface up to date with the current
technical situation.
1 Scope
This Technical Report describes the current realisations of Twisted Pair 1 medium interface solutions.
TP1 signal forms are not described in this technical report as they already form part of EN 50090-5-2.

A bus connection block can either consist of two separate parts notched together or of one single
inseparable block. When consisting of one single inseparable block, the colours indicating bus polarity (dark
gray-red) shall be clearly visible to the user and ensure proper and safe connection. In case of white/yellow
variation, white corresponds to minus where yellow to plus.
5 Medium interface realisation type 2
5.1 Introduction
This connector is intended for the automatic connection of TP1 DIN rail devices to the TP1 bus only when
snapped onto the DIN-rail. It consists of a data rail and a contact block, the latter consisting of a housing and
a set of spring contacts.
For ensuring connection between data rail and cable, requirements for a data rail to wire connector are
specified.
