Setup #2 - EIB Adresse 
The installer can assign different 
main group addresses, in the 
range from 0 to 15, when pro-
gramming the EIB bus coupler 
units (BCU) for the Revox 
Multiroom controller keypads. 
All keypads and/or their BCUs, 
which are used for controlling the 
Revox Multiroom System must 
have the same main group 
address (X). All other installation 
areas, e.g. lighting or heating, 
must be assigned a different 
main group address than the 
Revox EIB-Bridge. Otherwise, 
wrong interpretations may result. 
The main group address used (X) 
is set on page #2. Setting is done 
using the two softkeys – Address 
+. You do not have to confirm the 
address setting. Main address 5 
was used in the above example. 
In this case, all BCUs and/or their 
keypad units, which are used to 
control the Revox Multiroom 
System must also have the main 
group address 5 so that the 
controls work correctly. 
The definition of the middle (Y) 
and lower (Z) group addresses is 
handled by the Revox protocol. 
An individual group address YZ 
results from each combination of 
(Multiroom) zone, room and 
function. 
The easiest way of calculating 
the individual YZ group 
addresses is to use the Excel 
Configuration guide that can be 
downloaded from the Revox 
Homepage, ww.revox.de / 
Download/ Re:connect. 
You can see the room and zone 
assignments of a maximum 
configuration Revox Multiroom 
System on page 13. 
The address for rooms 1 – 8 in 
the corresponding zones is set 
through DIL switches on the 
M219 Additional room amplifier. 
You will find a description in the 
M219 Additional room amplifier 
Operating manual. 
Another convenient way of 
determining the room addresses 
is the Revox Multiroom planner 
PC software, which can be 
downloaded free of charge from 
the Revox homepage.
