Introduction

This quick guide discusses the BACnet functionality available on Irisys Vector Analytic devices, and how to configure it.

BACnet, or more specifically BACnet/IP ("BACnet over internet protocol"), is just one of the many different methods of retrieving count data from a Vector device. If you're undecided on the data retrieval mechanism to use, see also the sections on the REST API, HTTP Post and MQTT options.

BACnet is a common communication protocol that allows building systems to communicate with each other and provides control of various building systems such as heating, ventilation, air-conditioning, lighting, access control, etc. Because it is a standard protocol, even devices and equipment from different manufacturers can talk to each other, and by adding BACnet support to Vector, count data can be used as a feed into the various control systems.

For example, a Vector 4D sensor installed at an entryway to a room or floor plate will count people in to, and out of, that space. If the Vector 4D sensor counts all people out of the space, it will report this via BACnet/IP to the buildings BMS which can in turn automatically turn down the heating/cooling and/or switch off the lighting.

NOTE: This document applies to Vectors running firmware versions 2.0.157 and above. 
In order to access these settings, you must first make an initial connection to the Vector unit; see separate guide: Irisys Vector 4D - Making a Setup Connection

 

BACnet Configuration

Note BACnet is a Vector Analytic only feature. BACnet is not available on Vector Count variants.

Once you are connected to the Vector, the BACnet settings are accessed via the ‘Settings’ tab, then ‘BACnet’. Click the 'Enabled" checkbox:

Enter a unique Device ID.

Enter a port number on which the Vector 4D will advertise. 

Note: port 47808 equates to BAC0 in HEX, 47809 = BAC1, 47810 = BAC2, ... 47817 = BAC9. 

The Network options relates to the transmission of BACnet messages through BACnet routers.
