Static IP Address
The BACnet IP Address of the MicroTech II chiller unit
controller consists of the four-octet IP address followed by the
two-octet UDP (User Datagram Protocol) port number. The
BACnet/IP address is a six-octet value analogous to a MAC
(Media Access Control) address. The IP address portion of
the BACnet/IP address must be unique in the BACnet network
segment. The default UDP port number of the unit controller is
47808 (BAC0 in hexadecimal).

Consult with your network administrator for the information on
your network settings.
Multiple IP Subnets - BBMD
A BACnet/IP network may consist of multiple IP subnets
assigned the same BACnet network number. In this case,
a BBMD (BACnet Broadcast Management Device) allows
broadcasts to be transmitted to all other BBMDs on the BACnet
network. BBMDs allow devices on one network to distribute
broadcasts, or communicate, across multiple subnets. A
BBMD also provides for foreign device registration. This allows
a device on one network to communicate with a device on
another network by using the BBMD to forward and route the
messages.
The communication module can be registered as a foreign
device with a BBMD device. This is done by providing the
module with the IP Address and Foreign Device Time-To-Live
setting of the BBMD. Once entered, the module automatically

a read-only screen with a number of setup parameters. The
parameters that require setting depend on the data link layer (IP
or Ethernet) of the BAS network. The items that appear on the
page are relative to the selected BACnet layer. Device, Date/
Time, and Alarms require settings for all BACnet networks.
BACnet via Ethernet may not require network settings. However,
BACnet IP does require network settings. Note that the example

Follow these procedures if you can control the chiller unit
controller from its keypad/display or touchscreen interface, but
you are not able to communicate with the unit via the network.
Network Parameters
→ Verify that network parameters are set correctly as
shown in Table 4.
→ Make sure there are no duplicate devices on the
network (Device Name and Device ID, for example).
Network wiring
→ Check for loose connections and that devices are
plugged in properly.
→

→
when a static IP address is being used for non-DHCP
networks.
→
→ Verify if BBMDs are required. BBMD must be used
if the BACnet client and BACnet server are located on
this. Tracert shows all stations used to forward the
signal to another segment. See Figure 28 for the result
of a BBMD network as displayed by using the “tracert”
command.

→ Use the standard TCP/IP suite of tools to check
connectivity with other devices. Ping the unit controller
using these steps if the communication module is not
working:
1Select Start > Run on the Windows start bar
→ The “Run” dialog box opens
2Enter C:\>ping XX XX XX and press Enter
→ The ping result is displayed (Figure 29)
Figure 29: Successful Ping Result
→ If you get a response from that IP address, you are
connected to the communication module. If the ping
fails and you do not get a response, then there is an
issue with the network or the IP settings. Verify the
communication module and the PC network settings (see
).
