BACnet Configuration
This section describes how to set BACnet parameters using
the BACnet communication module’s built-in configuration
menu ( Figure 1 ). The BACnet configuration menu is accessed
using Microsoft Windows ® HyperTerminal ® or PuTTY. It is
assumed that the user is familiar with such an application.
Certain parameters are can also be configured via the BACnet
network (BAS). Parameters that can only be accessed
using the BACnet configuration menu are noted below. The
second part of this section, BACnet Commissioning and
Device Management , describes optional network testing and
verification tools available for the communication module.
The parameters listed below require configuration in order for
the communication module to properly integrate to the BACnet
network.
BACnet Device Properties
• Device Instance - must be set to a unique value on the
BACnet network
• Device Name - must be set to a unique value on the
BACnet network
• Location
• Units
• Description
BACnet MS/TP Settings
• MS/TP Baud Rate - must be set to match the speed
of the BACnet network. Valid values are 9600, 19200,
38400, or 76800. The baud rate must be set using the
BACnet configuration menu.
• MaxMasters - set to the highest address of a MS/TP
master on the network segment to reduce the MS/TP
token traffic and increase response time of the unit
controller. MaxMasters can be set from the BAS or from
the BACnet configuration menu.
• MAC Address / Address Switch - must be set according
to the BACnet network requirements. The MS/TP MAC
address can be set from the BAS or from the BACnet
configuration menu only when the physical address
switch (S3) is set to 255.
Accessing the BACnet Configuration
Menu
The BACnet communication module’s configuration menu is
accessed through the DB-9 serial connector on the module
itself. Any serial terminal device or application (such as
Windows HyperTerminal) can be used to view the menu and
change the configuration parameters.
Follow these steps to connect to the BACnet configuration
menu ( Figure 1 ):
1. Verify that the terminal application communication
settings are set to: 19200 bps, 8-data bits, 1-stop bit, no
parity, and no flow control.
2. Use a null modem serial cross over cable to connect the
computer to the BACnet communication module.
3. Once connected, press the ‘Enter’ key to display the
menu shown in Figure 1 .
4. Change the following parameters, if desired: Instance,
Name, Location, Description, MS/TP Baud Rate, and
Units.
5. Press ‘S’ to save the BACnet configuration settings.
6. Verify “Flash write – success” is shown for configuration
pages 1 and 2. Otherwise, save the settings again.
