Introduction
This programming guide discusses the BACnet message format provided from Irisys Vector units.
BACnet is just one of the many different methods of retrieving count data from a Vector device. Alternative data retrieval methods are the REST API, HTTP Post, MQTT, and relay outputs via the optional USB IO module.
BACnet works by publishing each configured register as an object which is viewable by a BACnet enabled controller.

Data Properties
A Vector 4D device will output its register values - up to a maximum of 32 register values.
The meaning of these values is entirely dependent on how the device is configured, and what register types and quantities have been added.
By default, a device will have just two registers configured representing ”Line 1” and “Line 2” footfall counting (usually 'IN' and 'OUT' count totals), but other line count registers and other types of registers can be added as required for the project application. An Occupancy (or 'Occupancy FIFO') register total is often used over BACnet in order to turn off lighting as the occupancy drops or decrease air con temperature as occupancy increases, for example.
The register values are exposed as Analog_Value:1 … Analog_Value:32.
