1 Overview
The DAP III control panel supports a BACnet communication with a BMS for the system
monitoring and control. This document describes all the requirements and configuration
steps to implement the interface with a DAP III panel using the BACnet MS/TP and
Bacnet IP protocol.
2 Hardware Requirements and Installation
2.1 Required Network Card
2.1.1 The BACnet MS/TP protocol interface requires a Data Aire RS-485 Multidrop
communication network card to be installed into the DAP III Display board.
The RS-485 Multidrop card part number is 160-400-383.
Figure 1: Data Aire RS-485 Multidrop Communications Network card
2.1.2 The BACnet IP protocol interface requires a Data Aire Ethernet network card to
be installed into the DAP III Display board. The Ethernet card part number is
160-400-385. This card is compliant with IEEE 802.3/802.3u 100BaseTX
Ethernet standard and auto-negotiation at 10Mbps/ 100 Mbps.

2.2 Network Card Installation
IMPORTANT NOTE: The DAP III panel supports one network connection at a
time therefore only one type of the network card can be
installed.
2.2.1 For BACnet MS/TP interface, plug an RS-485 Multidrop communication network
card to the Communication Header J1 of the DAP III Display board. Make sure
the End jumper is on “T” (Terminate) position if the installed unit is the last unit in
the communication loop. In some case, the End jumper may not be required,
check with the BMS manufacturer for the requirement of this End jumper. See
Figure 3 below for the DAP III Display board with an RS-485 Multidrop card
installed.
After installing the network card, go to Menu 6-1 – Unit & Network ID in Group
Menu 6 – Network to set the unit network ID number. Go to Menu 6-2 –Network
Protocol to configure or verify the network protocol. Menu 6-2 to 6-7 are locked
menus, refer to the DAP III Operation Manual for the procedure of how to unlock
these menus before enter values. It is recommended to reset the DAP III panel
after changing the network protocol or the unit ID number.

2.2.2 For BACnet IP interface, connect an Ethernet Communications network card to
the Communication Header J1 of the DAP III Display board. See Figure 4 for the
DAP III Display board with an Ethernet card installed.
After installing the network card, go to menu 6-1 – Unit and Network ID in Group
menu 6 to set the unit network ID and to menu 6-2 –Network protocol to
configure the network protocol. Menu 6-2 to 6-7 are locked menus, refer to the
DAP III Operation Manual for the procedure of how to unlock these menus before
entering IP address. It is recommended to reset the DAP III panel after changing
the network protocol or the unit ID number.

2.3 Network Wiring
2.3.1 For RS-485 Multidrop network connection, the 18 AWG or 22 AWG shielded,
twisted pair cable is recommended. The network wiring should be wired in the
multidrop fashion: The RS-485 devices are wired in parallel. The wiring should
start from the RS-485 port of the BMS Gateway module. See Figure 3 above for
the DAP III RS-485 network wiring terminations.

2.3.2 For the Ethernet connection, use the CAT-5 Ethernet cable. The DAP III panel
should be connected to the same network with the BMS by a network switch or a
network hub. Each unit requires having a dedicated IP address. Consult with
the building IT personnel or building network administrator on IP addressing.
3 Communication Port Setting
3.1 The RS-485 communication Port for BACnet MS/TP protocol is configured as
follow:
3.2 For BACnet IP communication UDP port setting, refer to the DAP III Operation
Manual for the procedure to enter an IP address and port setting to the DAP III.
The BACnet/IP UDP port (Listen port) in the DAP III is default to 47808.
