Meridian Plus Address Switches
Figure 4: New Meridian Plus Address Switch Setting
The Meridian Plus Zone Manager has two different
address switches. One is located on the main Zone
Manager board and one is located on the MiniLink board
that is located on the top of the Zone Manager board.
The Zone Manager board address should always be set
to address 17 on the Meridian Plus system. The
MiniLink board should be addressed with a unique num-
ber for each Zone Manager on the system. It is recom-
mended that you start with address 1 and address each
Zone Manager consecutively. See Figure 4 below for
detailed information.
