Device Configuration
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.
System/Subnet
: The DFC-304R3-240 is a Subnet device only. It cannot be
configured as a System device.
AREA
SYSTEM
SUBNET
Derived Network Addressing
The
DNA jumper
comes ON by default. This allows the device to automatically
configure a BACnet device address. This should NOT be removed unless you
are assigning a BACnet device number through software. The BACnet device
number should not be confused with the DIP switch setting, and each device
must still have a unique dip switch address even when using software to define
the device number.
DNA
Device Addressing
The Dip Switch is a binary switch. Each individual DIP switch represents a
unique value, which forms the device address when added together.
To set the address, simply move the switches that add up to the devices
desired address to the ON position.
Example: If the device is to be address 5 on the network, set the switch
numbered 4 and the switch numbered 1 (equals 5) to the On position.
Note
: Each device on the same MS/TP segment must have a unique DIP
switch address.
Refer to the DNA section of the
ORCAview Technical Reference Manual
, and

General System Description

System/Subnet devices.
