M203 EIB-Bridge 
The M203 EIB-Bridge establishes 
the bridge between on the one 
side the Revox Multiroom System 
and on the other side, the EIB 
Domestic facility management 
system. 
The data exchange occurs 
between the M203 EIB serial 
interface and a serial EIB data 
interface for bus couplers. 
Installation 
The M203 interface can be 
installed easily and quickly. 
There are two types of fixing 
available. 
Connection plan 
The M203 EIB-Bridge is only 
designed to handle communi-
cation with an EIB data interface 
and cannot receive any other 
protocols. The normal RS232 
software (203-1) can be loaded 
using the Revox programmer. 
The EIB software is not copy 
protected.
1) The four outside fixing holes 
are used for a permanent 
installation. 
2) Revox recommends using 
the two slots on the side for a 
variable installation.
