Multiple MDU Set-Up Codes
MOTOR DRIVE UNIT (MDU) SETUP - MULTIPLE MDU's
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.
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.
Scene 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 activated it on.
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.
Any keypad or interface
CANNOT
be wired to more
than one MDU.
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.
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 setting
of the MDU it is wired to.

IR Address:
Used to set the IR address a MDU will respond to. Some IR hand controls have the ability to control
subgroups of shades within a group, as defined by the room address described above. There are 16 subgroups available.
Each IR address (subgroup) is made up of two parts, the IR address number (1, 2, 3, 4, 5, 6, 7 or 8) and its shade location
(F or r), the FRONT shade or the REAR shade. 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 information on how the IR address affects how the system is controlled by keypads or
interfaces.
