Introduction
The VAV T4 RT VAV Zone Controller BACnet®Communication Module User Guide provides information about using
the controllers in the zoning system with BACnet communications feature. The BACnet communication protocol for
building automation and control networks enables communication between client devices within a network. The
controller provides a BACnet network interface between BACnet client devices and DEOS Controller series devices. It
uses the BACnet Master Slave/Token Passing (MS/TP) protocol at the BACnet MAC layer.
Pre-requisites
The BACnet communication user guide assumes that you are familiar with the concepts of BACnet and its
terminology.
Advantages of BACnet
BACnet enabled controllers have the following advantages:
Quick Message Transmission. The controller uses a synchronous implementation for BACnet messages
making it quick and efficient. Each BACnet confirmed service request is answered as quickly as possible
without using the Reply Postponed frame. The MS/TP implementation is performed within Tusage_delay of
15 minutes to ensure a Tusage_timeout value within 20 minutes.
MS/TP Support. The controller supports a Full Master Node state machine for MS/TP. The Max_Master and
the instances are configured to the device object through BACnet WriteProperty service or via the device's
Programming Mode. The MAC address and the MS/TP baud rate setting of 9600, 19200, 38400, and 76800
are also set through the BACnet Write Property service or via the device's Programming Mode. In
Programming mode, the device is configured through the device’s keypad. For more information about the
WriteProperty, refer to Table 3 - Object Types Supported.
BIBB Support. The controller functions the same way as the B-ASC type profile server and supports the
specific BIBB as per their relevant definitions.
oDS-RP-B
oDS-RPM-B
oDS-WP-B
oDS-WPM-B
oDM-DCC-B
oDM-DDB-B
oDM-DOB-B
oDM-RD-B
oDM-TS-B
oDM-UTC-B
oDS-COV-B
oDS-COVP-B
oSCHED-WS-I-B
Object Support. The controller supports a fixed list of BACnet visible values, which appear as Present_Values
of various BACnet standard object types in addition to a device object. For more information, refer to Table 3 -
Object Types Supported.
Alarms. The controller supports indication of various alarm conditions through value changes in properties of
several objects. However, it does not generate BACnet event notifications.

BACnet Properties Configuration
To establish communication on the network, and guarantee a unique ID of devices in a BACnet system, the following
properties may have to be configured.
Table 1 - BACnet Properties Configuration
Property
Default Value
Configuration
MAC Address
000
Set to a unique address on the network between 000 and 254.
The value can be set manually via the menu.
The value can be set manually through the WriteProperty service to
Device Object.proprietary-property#1000 MSTP-Address.
The values from 128-254 represent MS/TP non-token passing slave
devices.
Device Instance
Auto
The controller automatically configures its device instance to 877,000 +
MAC address.
The value can be set manually via the menu.
The value can be set manually through the WriteProperty service to
Device Object.Object_Identifier.
The device’s Object_Identifier is a combination of the Device
Object_Type (8) and the Device_Instance (0-4194302), therefore its
decimal or hexadecimal representation tends to be incomprehensible.
For example, the Device_Instance=1000 has an equivalent
Object_Identifier of 0x020003E8 hexadecimal or 33555432 decimal.
Baud Rate
0 = Auto
The controller configures its baud rate automatically by detecting the
network upon connection.
The value can be set manually from the available values of (0) Auto, 9600,
19200, 38400, and 76800.
Max_Master
127
Configure Max_Master value to increase network efficiency when there are
less than 127 devices on the network.
The Max_Master value can be changed through the WriteProperty service
to Device Object.Max_Master.
For more information, refer to the MAC Address and Max_Master section.
Device Object.Object_Name
Name of the
device
Configure the name of the device through the WriteProperty service to
Device Object.Object_Name. For example, VAV T4 RT.

Configuration Options
The following Configuration options enable you to configure and run the BACnet features of the controllers quickly.
Quick Setup
Configure the controller for BACnet communication without programming.
1. Ensure that no other device on the network has a MAC address of 0 (the controller's default address).
2. Connect the controller to the network and power it up.
3. The controller automatically configures the baud rate and device instance allowing BACnet Property
Configuration through the Write Property service. See Table 1 - BACnet Properties Configuration.
4. Repeat the steps for each controller.
Manual Setup
Configure the controller for BACnet communication with programming.
1. Access Operation Mode (jumper set to RUN position).
2. Press and hold both function buttons for 5 seconds to access the Quick Access menu.
3. Enter the password, 637.
4. Follow the instructions to configure the MAC Address, MAX Master, Device Instance, and Baud Rate,
manually.
5. Disconnect the power to the controller, connect the controller to the network, and connect the power
again.
MAC Address and Max_Master
The MAC address must be unique on the entire MS/TP network. However, having a unique MAC address and a high
baud rate does not guarantee efficient operation of the controller and other MS/TP units on the MS/TP network. Some
MAC address and Max_Master combinations are more efficient than others. BACnet requires token-passing units to
occasionally “poll” for other masters based on the MAC address and Max_Master.
A poor combination of MAC addresses and Max_Master can lead to a slower network due to lost time polling for
masters that are not present. Unless there are 126 other units on the MS/TP network, the default Max_Master value of
127 is not the most efficient choice for the controller. The Max_Master default value of 127 was selected to ensure
that any master, specifically a BACnet client can be found when the controller is initially started.
Examples of MAC Address and Max_Master Configurations
The following are some of the examples to indicate the optimum combination of Mac address and Max_Master
configurations to ensure a quick and efficient output.
Example 1
MAC=0. Max_Master=127
MAC=1, Max_Master=127
This configuration is slow and inefficient because every time either unit is required to find another master unit, it has to
poll 126 units until it finds the right one to pass the token.
Example 2
MAC=0. Max_Master=5
MAC=1 to MAC=4 are not used
MAC=5, Max_Master=5
This configuration is better than Example 1 but it is still not optimal. The Max_Master is set to the most efficient value
but the gap between the two MAC addresses is high. Therefore, each unit must poll four units until it finds the right
one to pass the token.

BACnet Communication Module User Guide

Page | 4
Example 3
MAC=0, Max_Master=1
MAC=2, Max_Master=2
This is an incorrect configuration. The MAC=0 will never find MAC=2 because it will never poll for the master MAC
address=2.
Example 4
MAC=0. Max_Master=3
MAC=1, Max_Master=3
MAC=2, Max_Master=3
MAC=3, Max_Master=3
This is an efficient configuration as the units are numbered consecutively and the MAX_Master is set to the most
efficient value. As a general guideline, the most efficient setup for an MS/TP network is one in which the units are
consecutively numbered starting at MAC address 0 and having Max_Master=the maximum MAC address in the
system. If consecutive numbering is not possible, then the next most efficient setup is one in which all units have
Max_Master=the maximum MAC address in the system.
Copy Config
Copy and broadcast the entire configuration of a controller over the network to controllers of the same type using the
Copy Config feature.
1. Access Operation Mode (jumper set to RUN position).
2. Press and hold both function buttons for 5 seconds to access the Quick Access menu.
3. Enter the password, 637.
4. Scroll to Copy Config programming menu and select Yes. Follow the rest of the onscreen instructions.
Note: A Copy Config can also be executed via BACnet. See AV.165, AV.166, AV.167, and BV.90 in Table 6 -
Object Table Information: Analog Value (AV) and Table 9 - Object Table Information: Binary Value (BV) for details.
Network Reset
Reset the controller via BACnet using the Reinitialize Device service. The Reinitialize Device service can be
accessed using the following password: nep.
The Reinitialize Device service has two types of reset such as:
Warm Reset. The Warm Reset restarts the controller with actual configuration.
Cold Reset. The Cold Reset restarts the controller with Factory configuration.
Warning: The Cold Reset erases the actual configuration when setting the MSTP address. Therefore, exercise
caution while performing a Cold Reset.

Out_of_Service Property
DEOS controllers offer the use of the Out_of_Service writable property. When the value of this property is set to True,
it disconnects the object from the physical input, enabling you to input other values. This is useful for special
applications or while troubleshooting. For example, you can ignore the temperature read from a sensor and input the
desired temperature value in order to perform specific tests.
For security reasons, a timeout will set the Out_of_Service property back to False after 15 minutes. This value can be
modified to between 0 and 120 minutes (For more information, see proprietary property #1002 in Table 2 - Device
Object Properties).
