Introduction
This document provides information on using the Neptronic controller communications feature. This product
provides a BACnet®network interface between BACnet®client devices and Neptronic controllers. It uses the
BACnet®Master Slave/Token Passing (MS/TP) protocol at the BACnet®MAC layer.
This document assumes you are familiar with BACnet®and BACnet®terminology.
BACnet®Overview
Performance
The controller uses a synchronous implementation for BACnet®messages. Each BACnet®confirmed service
request is answered as quickly as possible without using Reply Postponed. In particular, MS/TP implementation
performs within Tusage_delay of 15ms in order to assure Tusage_timeout values within 20ms.
Support for MS/TP
The controller supports a Full Master Node state machine for MS/TP. All parameters are configured via the
thermostat menu or via the BACnet®WriteProperty service. Changes made via the WriteProperty take effect
immediately and does not require a restart of the controller. For more information the configurable properties,
please refert to the Getting Started section on page 3. For more information on the thermostat menu, please
refer to the controller’s Specification & Installation Manual for more details.
BIBB Support
The controller generally behaves as a B-ASC type profile server. The following specific BIBBs are supported per
their relevant definitions in Annex K to BACnet®: DS-RP-B, DS-RPM-B, DS-WP-B, DS-WPM-B, DM-DDB-B,
DM-DOB-B, DM-DCC-B
Object Support (in general)
The controller supports a table-based fixed list of BACnet®-visible values which appear as Present_Values of
various BACnet®standard object types, in addition to a Device object.
Alarms
Although the controller supports the ability to indicate various alarm conditions through value changes in
properties of several of its objects, it does not generate BACnet®Event Notifications.
Features
Neptronic controllers also offer the following time-saving features.
Auto Baud Rate Detection
The controller automatically configures its baud rate by detecting the network speed upon connection.
Auto Device Instance Configuration
The controller automatically configures its device instance to 153000 + MAC address.
Copy Configuration
Copy the controller’s entire configuration and broadcast it to other controllers of the same type on the same
network.

Getting Started
The following BACnet®properties are configurable and may need to be modified to effectively establish
communication on the network and to guarantee uniqueness of each device in a BACnet®system.
MAC Address (Default: 000)
Set to between 000 and 127 via DIP switches on the controller. Can also be set manually to between
000 and 254 via thermostat menu* (128-254 represent MS/TP non-token-passing slave devices).
Device Instance (Default: Auto)
The controller automatically configures its device instance to 153000 + MAC address. Can also be set
manually via thermostat menu* or 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. While it’s the device’s Object_Identifier property that can be changed using a
BACnet®WriteProperty service, this document refers mostly to Device_Instance.
Baud Rate (Default: 0 = Auto)
The controller automatically configures its baud rate by detecting the network speed upon connection.
Can also be set manually via thermostat menu* or through the WriteProperty service to Device
Object.proprietary property #1001. This value is Unsigned type, and available values are 9600, 19200,
38400, 76800.
Max_Master (Default: 127)
To increase network efficiency or if there are less than 127 devices on the network, the Max_Master
value can be configured through WriteProperty service to the Device Object.Max_Master. For more
information, refer to the MAC address and Max_Master section on page 4.
Device Object.Object_Name
Name of device, for example EVFB11WQ4. This value can be configured through WriteProperty service
to the Device Object.Object_Name.
* NOTE: When referring to the thermostat menu in this section, it includes the Quick Access Menu when in
operation mode (RUN) and the Installer Menu when in programming mode (PGM).Refer to the controller’s
Specification & Installation Manual for more details.
Quick Setup
Take advantage of the controller’s Auto Baud Rate Detection, Auto Device Instance Configuration, and default
Max_Master value, to get up and running with no programming.
1) Using the DIP switches located on the controller, set a unique MAC address.
2) Connect the controller to the network and then power up the controller. The controller automatically
configures the baud rate and device instance.
3) Repeat steps 1 and 2 for each controller.
Manual Setup
If your site has more than one EFCB network and/or you wish to use a Device_Instance other than 153,000,
follow these instructions.
1) With the thermostat in Operation Mode (jumper = RUN), go to the Quick Access Menu by pressing and
holding both function buttons on the thermostat for 5 seconds. Refer to the controller’s Specification &
Installation Manual for more details.
2) Enter the password (637).
3) In this mode you can manually configure the MAC address, Device Instance and Baud Rate.
4) Power down the controller, connect the controller to the network and then power up the controller.

5) Repeat steps 1 to 4 for each controller.
6) To increase network efficiency or if there are less than 127 devices on the network, the Max_Master
value can be configured through WriteProperty service to the Device Object.Max_Master. For more
information, refer to the MAC address and Max_Master section on page 4.
Copy Config
Copy the controller’s entire configuration and broadcast it to other controllers of the same type on the same
network.
1) With the thermostat in Operation Mode (jumper = RUN), go to the Quick Access Menu by pressing and
holding both function buttons on the thermostat for 5 seconds. Refer to the controller’s Specification &
Installation Manual for more details.
2) Enter the password (637).
3) Scroll to “Copy Config” and select yes. Follow onscreen instructions.
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
of 127 is not the most efficient choice for the controller. The Max_Master default of 127 was selected to ensure
that any master, specifically a BACnet®client, can be found when the controller is first started.
Example 1:
This example 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.
MAC=0. Max_Master=127
MAC=1, Max_Master=127
Example 2:
This example is better but it’s still slower. The Max_Master is set to the most efficient value; however because
of the gap between the two MAC addresses, each unit must poll 4 units until it finds the right one to pass the
token.
MAC=0. Max_Master=5
MAC=1 to MAC=4 are not used
MAC=5, Max_Master=5
Example 3:
This example is an incorrect configuration. The MAC=0 will never find MAC=2 because it will never poll for the
master MAC address=2.
MAC=0. Max_Master=1
MAC=2, Max_Master=2
Example 4:
As a general guideline, the most efficient set up for an MS/TP network is one in which the units are
consecutively numbered starting at MAC address 0 and all have Max_Master=the maximum MAC address in
the system. If consecutive numbering is not possible, then the next most efficient set up is one in which all units
have Max_Master=the maximum MAC address in the system.
MAC=0. Max_Master=3
MAC=1, Max_Master=3
MAC=2, Max_Master=3
MAC=3, Max_Master=3

Out of Service
Neptronic controllers offer the use of the “Out of Service” writable property. When set to true, this property
disconnects the object from the physical input, enabling you to input other values. This could be useful for
special applications or when 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 there is a timeout that will set the Out of Service property back to false after 15 minutes.
This value can be modified to between 0 and 120 minutes (see proprietary property #1002).
1Present_Value property is writable for every AV object except: AV.1, AV.2, AV.3, AV.42, AV.46, AV.49, AV.68, AV.69, AV.98
2 Out_of_Service property is writable for objects that Present_Value is not writable: AV.1, AV.68, AV.69. Object will automatically return to
normal after a programmable period of time. See Proprietary property #1002 of Device object.
3Present_Value property is writable for every BV object except: BV.7, BV26, BV27, BV28, BV36, BV37
4Out_of_Service property is writable for objects that Present_Value is not writable. See list above. Object will automatically return to normal
after a programmable period of time. See Proprietary property #1002 of Device object.
5MSV object states number and text can vary depending of system set-up. Use carefully.
6Present_Value property is writable for every MSV object except: MSV.9, MSV.14
