representing the network level that it will reside on in the
network architecture (area, system, subnet). Other than
the one device acting as a router/gateway, all other
devices on the same network segment must be configured
the same way.
Depending on the model, the lighting controller may be
configured as follows:
• Area – Configures the controller as an area-level
device, on a network of area devices. This is an
option only available on the Ethernet model and is
used when the device is connected to an Ethernet
network (typically between buildings) and is acting
as a router/gateway from one LAN to either a
network of system devices or subnet devices.
• System – Configures the controller as a system-level
device, on a network of system devices. This is the
setting when the device is connected to an Ethernet
or BACnet MS/TP network with other system
devices, or is a single head-end device for a network
of subnet devices. For most applications, this is the
recommended setting.
• Subnet – Configures the controller as a subnet-level
device on a subnet of similar devices. This is the
setting when the device is connected to a BACnet
MS/TP network with other subnet devices.

Derived Network Addressing (DNA) Jumper
Derived network addressing (DNA) is a method for
organizing and configuring devices on a network segment
in an efficient manner. It is a simple scheme whereby area
devices can group system devices and system devices can
group subnet devices. This setup provides an easy way to
monitor and manage the devices attached to a network
and provides a manageable representation of the
relationships between the devices on the network. One of
the controllers on the network segment is set as the area
device, which then reconfigures all the devices on the
network to follow the address of the area device and
network number scheme. The system device appears
underneath the area, takes the addresses from the area
device, and adds on its own address and network number
to reconfigure the subnet devices. Subnet devices follow
the same rules as the system devices. The left pane of
Navigator displays the devices so that the network
architecture level is clear.
Derived network addressing works in conjunction with the
device type setting and refers to the ability of inheriting
portions of its address from higher-up devices on a
BACnet network. It may be enabled or disabled via jumper
setting, illustrated in Figure 9, as follows:
• Enabled – With the jumper in place, the controller
automatically obtains portions of its overall BACnet
device address (as related to area and system) from
higher-up devices on the network. This is the
preferred method of addressing the controller as
device addresses.
• Disabled – With the jumper removed, the device does
not obtain any portions of its address from higher-up
devices.

Controller Address DIP Switches
The controller address DIP switch, illustrated in Figure 10,
has eight individual switches that can be set to ON or OFF.
The address is calculated based on the binary number
depicted by the ON or OFF position of the switch and
their location. For example, if switches 1 and 4 are ON
and all other switches are OFF, the address is 9 (= 1*2
0 +
1*2 3 ). Depending upon the device type and DIP switch
setting, the controller will have a unique address, as shown
in Table 3.
