BACnet MS/TP Network
What is BACnet?
BACnet MS/TP is a communication protocol for
communication between LUME20 and the building
automation network. BACnet communication allows the
end user to verify rooms are operating as expected and set
up trends to monitor safety
and any alarms that occur.
LUME20 requires a connection to BACnet to transmit its
information to the Building Management System (BMS).
Network Addressing
When configuring LUME20, the user needs to assign the
unique addressing for the device.
On any BACnet MS/TP network:
• MAC Address can be between 0 and 127 and
must be unique to the MS/TP segment.
• Device Instance can be between 0 and 4,194,303
and must be unique to the facility.
• Baud Rate can be 9,600, 19,200, 38,400 or 76,800
and must match that of the Router/System
Controller for the MS/TP segment.
Typical BACnet Wiring
BACnet Points
See LUME20 Product Submittal at AntecControls.com for
BACnet Points List.
Physical Connection
BACnet consists of a three-wire network architecture.
Daisy chain the +, - and COM connections of all devices on
the network segment. A BACnet MS/TP segment has a
limit of:
• Maximum of 32 devices
• Maximum length of 1050 ft. (320 m) for the whole
segment
When using shielded cable, ground the shield at one end of
the network segment only. Connect the shield of the cable
entering a device to that of the cable exiting the device.
Terminate the MS/TP network segment at each end of the
network segment by connecting a 120-ohm resistor
between the + and – terminals. Remove the termination
resistor or disable any network terminations on all devices
when adding devices to an existing network segment.
Wiring Requirements
Refer to your Antec Controls Wiring Diagram Package for
typical wiring requirements and recommendations.
CAUTION
When using non-isolated power supplies (i.e. A transformer
with the secondary common connected to ground), do not
reverse 24VAC polarity on any device, as it is critical to the
network health.
