INSTALLATION & APPLICATION GUIDE
Product Description
The DNS-14 BACstat I is an intelligent room sensor with four buttons and
a 3-digit LCD display that is used with Delta's product line of BACnet
Application Controllers. It is capable of communicating on Delta's
proprietary LINKnet network or directly on a BACnet MS/TP network
using the MS/TP BACnet protocol.
When connected to an Application Controller on a LINKnet network the
DNS-14 provides programmable remote sensor capabilities to the
controller. Up to 12 devices may be connected to the LINKnet network,
depending on the controller, where associated BACnet objects located in
the Application Controller make the DNS-14 accessible to the rest of the
system. These same objects in the Application Controller are used in
programming each DNS-14 for various functions and applications.
When connected on an MS/TP network the DNS-14 functions as an independent Native BACnet sensor
device, similar to any other MS/TP device. Each DNS-14 is configured for operation (including the use of its
buttons and display), and can receive commands for mode and setpoint changes from another device across
the network (i.e., DCU or other System Controller with V3.22 firmware).

Page 4: Network & Cabling Requirements
Power The DNS-14 BACstat requires a 24 VAC @ 2 VA power supply, typically an isolated Class II transformer. More than one device – not including DCUs or V2 products – may be connected to the same transformer, providing the transformer is properly sized, including line losses, and polarity is observed between controllers (in regards to 24~ and GND). -
Page 5: Network Topology
Delta Controls Network Topology BACstats Configured as MS/TP Subnet Devices With V3.21 firmware or higher, one possible MS/TP network architecture has the MS/TP devices configured as Subnet devices, allowing BACstats to reside on the MS/TP network with other Subnet devices. Note that V3.21 requires a DCU, while V3.22 or higher may use any System Controller instead. -

Delta Network Sensor: BACstat I DNS-14 (Rev 1.6) Installation Guide Network Communications Setup BACstats communicate on an MS/TP network at a default speed of 76,800 bps. Refer to the ORCAview Technical Reference Manual for further detail on configuring the MS/TP network or changing baud rates, etc. - Page 7 Delta Controls Use the arrow buttons to navigate through the menu options. Once you have navigated to the desired item you wish to display or change, wait a brief moment for the current value to begin blinking, whereby you can use the arrow buttons to make any necessary changes.

Page 8: Application Notes
Application Notes OBJECTS The following is a list of predefined or “fixed” objects that reside in the DNS-14, which you cannot create or delete. When connected to an MS/TP network, these objects are readily accessible over the network. When connected to a LINKnet network, many of these objects are mapped into matching AI or AV objects residing in the Application Controller above. - Page 9 (both display & button handling and local control) and then write any necessary GCL in another controller for additional strategies. For example: Through the Configuration Menu, you typically configure the DNS-14 display and buttons to functional locally, so GCL programs are not necessary for handling the display value or adjusting setpoint (i.e., AV15 = 4.0).
- Page 10 Delta Network Sensor: BACstat I DNS-14 (Rev 1.6) Installation Guide GCL Programming All GCL programming for BACstats on a LINKnet network is written in the Application Controller that the BACstats are connected to, using the mapped objects resident in the Application Controller.
