Supported Quantity
The Q.RCU-D-xx sensor connects to the controller’s Subnet Port.
Other devices may also be connected to this port in a daisy-chained
fashion (see the controller’s datasheet for compatibility information
and supported quantities).
Each controller supports a maximum number of Q.RCU-D-xx sensors.
The Subnet ID of all Q.RCU-D-xx sensors must be set to be within the
shown addressing range.
Q.RCU-D-xx Serie sensors and Q.RCU-DC-xx Series sen-
sors share the same Subnet ID range: the same adress
CANNOT
be assigned concurrrently to an Q.RCU-D-xx
Series sensor
AND
to a Q.RCU-DC-xx sensor

1. Adding devices to the subnetwork decreases the system
responsiveness. This may be the origin of a certain delay, which
could be an issue for commands needing a fast response such as
lighting and shades/sunblind commands.
2. The indicated adressing ranges are specific for each group
of device.
4 different Subnet ID codifications are used on the Q.RC
Subnetwork :
-
1 for Q.RCU-LCD sensors
-
1 for Q.RCU-D-xx and Q.RCU-DC-xx sensors
-
1 for Q.RCS-MS-PL multi-sensors
-
1 for Q.RCE-xx Light/Blind expansion modules
Consequently, a Q.RCU-LCD-x sensor and a Q.RCU-DC-xx
sensor can have the same Subnet ID, but an Q.RCU-D
sensor and a Q.RCU-D-xx sensor must have a different
Subnet ID
3. A controller can support a maximum of two (2) Q.RCU-x models
equipped with a CO
2
sensor. Any remaining connected Q.RCU-X
Sensor models must be without a CO
2
sensor.
Dipswitch Location and Identification
Q.RCU-D-xx sensors have the following onsite configurable dipswitch.
