Configuring the MDU
M U LT I P L E M D U S E T- U P C O D E S
Program each MDU per instructions on page 11.
Link Address: Each MDU must be set to a unique Link Address number to allow the MDU's to communicate on the communication
link. There are 64 link addresses available, meaning the maximum number of MDU's in a single system is 64.
Room Address: The room address groups MDU's on the communication link. A group is defined as all MDU's with the same room
address number. There are 32 room addresses available in a single system, therefore, a system can have up to 32 groups.
Typically, all MDU's in a room will be set to the same room address. Use the room address to help determine how keypads will
control the MDU's in the system. Refer to the control station setting table below for information on how the room address setting
affects how the system is controlled by keypads or interfaces.
IR Address: Used to set the IR address a MDU will respond to. Some IR hand controls have the ability to control subgroups of
draperies within a group, as defined by the room address described above. There are 8 subgroups available. Each IR address (sub-
group) is made up of two parts, the IR address number (1,2,3 or 4) and its drapery location (F or r), the FRONT drapery or the REAR
drapery. Any number of MDU's can have the same IR address. The IR address can also be used to determine subgroups
of the MDU's when a keypad or interface is used to control the system. Refer to the control station setting table below for informa-
tion on how the IR address affects how the system is controlled by keypads or interfaces.
Control Station: Determines which MDU's in the system will respond to a "Group" keypad or "Group" interface control that is
wired to the MDU being setup. It is not necessary to change the control station setting of an MDU that does not have any keypads
or interfaces wired to it.

Preset Lockout: Turns off the ability to set or adjust PRESET stop points. To activate, set the scene lockout
setting to 1. To deactivate, set the scene lockout setting to 0. Changing this setting on any MDU will adjust all the
MDU's in the system. It is not necessary to deactivate the scene lockout setting from the same MDU it was acti-
vated it on.

SPECIAL NOTES:
There are two types of Sivoia keypads and
interfaces, group and individual types. The
table to the left describes how a group type
controls a system depending on the
setting of the MDU it is wired to. An individual
type only controls the MDU it is wired to,
regardless of the
and
is wired to.
Group keypads/interfaces and individual
keypads/interfaces can be wired to the same
MDU. A maximum of 9 keypads/interfaces
can be wired to one MDU.
Any keypad or interface CANNOT be wired to
more than one MDU.
