DEVICE TYPE
Various products have the capability of being configured as one of several
possible device types, which represents the network level that it will reside
on in the network architecture (Area, System, Subnet). Other than the one
device acting as a router, all other devices on the same network segment
must be configured the same. Controller may be configured as follows:
Area
"
Configures the device as an Area level device.
System
<
Default
>
"
Configures the device as a System level device.
Subnet
"
Configures the devices as a Subnet level device on a subnet of
similar devices.
For further information, refer to the Delta Controls System Description
Document.
NOTE: This also determines where the DIP or MAC address is mapped
into the devices BACnet address and which other portions of its BACnet
address are inherited when DNA is enabled.

DERIVED NETWORK ADDRESSING (DNA)
Derived Network Addressing (DNA), which is dependent on the
Device
Type
setting and refers to the ability of inheriting portions of its address
from higher-up device’s, is enabled when the jumper is in place across the
jumper pins, and disabled when the jumper is removed.
Enabled <
Default
>
"
With the jumper in place, the controller
automatically obtains portions of its overall BACnet device
address (as related to Area and possibly System) from higher-up
devices on the network. This is the preferred method of
addressing the controller in a system of Delta devices.
Disabled
"
Without the jumper, the controller does
not
obtain any
portions of its address from higher-up devices. Instead, default
numbers are assumed (for Area, and System
or
Subnet), which
may be modified via software. This method of addressing is
likely most useful when the controller is installed in an OEM or
other vendor installation and Delta products do not exist higher-
up in the network architecture or where address ranges are pre-
assigned for the installation.
NOTE: Whether or not Derived Network Addressing is enabled, the
Addressing DIP switches are always used to set the device MAC address
and the Subnet device number in the overall BACnet device address.
