BACnet Object Description

Device object

Event Table

Object Processing

The properties Object name, Description and Location of the Device Object support up to 32 characters (all other character strings are read-only).
The device does not support the CreateObject and DeleteObject service.

RS-485 Termination Resistance

The jumper placed beside the RS-485 A, B and M wire connectors must be closed (set to ON) for activating the 120 Ohm RS-485 termination resistance.
The termination resistance must be activated if TA-Smart is at the end of a daisy chain or if it is not part of a daisy chain.

Wiring Diagram

TA-Smart

Note:

1. A, B and M terminals are NOT isolated from all other terminals.
2. GND (M – 0V) is common to power supply, analog signals and RS 485.
3. In case of AC power supply, L24 and M should be connected to the same phase for each TA-Smart.
4. GND (0V) of RS 485 should be connected to 0 VAC/VDC on the controller side.
5. GND (0V) of analog input/output should be connected to 0 VAC/VDC on the controller side.
