4.4 BACnet Objects and Network Configuration
Transmission types
•
Physical layer: Wi-Fi 802.11 b/g/n
•
Protocol: BACnet/IP
• UDP Port Number: BAC0 (47808)
•
MAC address: Wi-Fi chip MAC address found written on the back side of
thermostat or in Engineering Menu item (Phy3). This can assist when multiple Wi-Fi
thermostats are installed.
•
Device Instance: 600001
Initial Configuration
All configuration parameters are settable through use of the buttons on thermostat by
entering the
Engineer Menu
, or once installed on the BACnet network, configuration can
also be altered using BACnet commands. Network command-based configuration can also
be accomplished using a Wi-Fi enabled laptop/computer/tablet/smart phone and
Contemporary Controls’ free BACnet Discovery Tool.
Wi-Fi Communication Configuration
Overview
The BAST-321HP-BW2 Wi-Fi thermostat is preconfigured with a BACnet Device Instance
of 600001 and a UDP Port Number of 47808 (decimal) equivalent to BAC0 (hexadecimal).
Addressing
A unique Device Instance Number throughout the entire BACnet internetwork is required
to distinguish the device from all other BACnet devices. When more than one BASstat is
installed at the same time, their Device Instance Number must be configured prior to
connecting to the BACnet/IP network or BACnet communication will fail due to duplicate
device instances.
Device instance can be modified in Engineering Menu items (dEVH) – high bytes and
(dEVL) – low bytes. Device Instance = (dEVH)*1000+(dEVL). Device Instance example: if
(dEVH) is set to 4194 and (dEVL) is set to 7, Device Instance Number = 4194007. Device
Instance Number can also be changed by writing to BACnet object [ AV21 ] Device Instance
once the thermostat is online. The BACnet UDP Port Number can be configured in
Engineering Menu item (UdP).
