Parameter
3
Range/Default
Description/Notes
Device Object Name
Up to 17 characters
Default: Varies
This name must be unique throughout the entire BACnet network. The last 6 characters of
the default are the last 6 digits of the MAC Address, which is on a printed sticker affixed to the
BACnet communication module.
Device Instance Number
0 - 4194302
Default: 1579312
Device Instance of the BACnet communication module. This must be unique throughout the
entire BACnet network.
Act IP
If DHCP set to On:
Address automatically assigned by
network
If DHCP set to Off:
Address = Given IP
Actual IP Address of the BACnet communication module. This parameter is not changeable.
Displays 0.0.0.0 if the network is not connected when power is applied to the unit controller. If
DHCP is set to On (enabled), the network automatically assigns this address. If DHCP is set to
Off (not enabled), the Actual IP Address is set equal to the Given IP Address (Gvn IP) provided
the network is connected when Apply Changes is set to Yes.
Gvn IP
Default: 127.0.0.1
Given IP Address of the BACnet communication module. The BACnet IP address consists of the
four-octet IP address followed by the two-octet UDP (User Datagram Protocol) port number. The
IP address portion of the BACnet/IP address must be unique in the BACnet/IP network segment.
Set the four-octet IP Address to match the Static IP Address.
Gvn Msk
Default: 255.255.255.0
Given Subnet Mask of the BACnet communication module. Set the Given Subnet Mask to match
the Static Subnet Mask Address.
Gvn Gwy
Default: 127.0.0.1
Given Gateway Address of the BACnet communication module. Set the Given Gateway Address
to match the Static Gateway Address.
Act Msk
If DHCP set to On:
Address automatically assigned by
network
If DHCP set to Off:
Address = Given Subnet Mask
Actual Subnet Mask of the BACnet communication module.
Displays 0.0.0.0 if the network is not connected when power is applied to the unit controller. If
DHCP is set to On (enabled), the network automatically assigns this address. If DHCP is set
to Off (not enabled), the Actual Subnet Mask is set equal to the Given Subnet Mask (Gvn Msk)
provided the network is connected when Apply Changes is set to Yes.
Act Gwy
If DHCP set to On:
Address automatically assigned by
network
If DHCP set to Off:
Address = Given Gateway Address
Actual Gateway Address. Item remains blank if the network is not connected when power
is applied to the unit controller. If DHCP is set to On, the network automatically assigns this
address. If DHCP is set to Off, the Actual Gateway Address is set equal to the Given Gateway
Address (Gvn Gwy) provided the network is connected when Apply Changes is set to Yes.
DHCP
2
Off or On
Default: On
Dynamic Host Configuration Protocol (DHCP) is a network protocol that enables a server to
automatically assign an IP Address. Set to Off if a static IP Address is needed. See
for more information.
UDP Port
Default: 47808 (BAC0 hex)
User Datagram Protocol. The UDP Port allows host-to-host communication via the IP network
and is used to identify the application process in the destination unit. Only change the UPD Port
if there are multiple subnets. See network administrator before modification.
Unit Support
English or Metric
Default: English
Controls the type of units that are passed through BACnet.
NC Dev 1
1
0-4194303
Default: 0 (no device)
Alarm Recipient Device 1. This is the device instance of the BACnet workstation or device that
will receive the alarm notification. Use this in place of the Recipient List in the Notification Class.
NC Dev2
1
0-4194303
Default: 0 (no device)
Alarm Recipient Device 2. This is the device instance of the BACnet workstation or device that
will receive the alarm notification. Use this in place of the Recipient List in the Notification Class.
BACnetBSP
Varies
Basic Support Package. Indicates the communication module firmware version. The BSP is
read-only.
1. Parameter must be configured via the unit controller display menu.
2. The BACnet communication module defaults to DHCP-enabled. See your system integrator for additional information regarding BACnet IP networks with DHCP
functionality.
3. The parameters shown in boldface text are required for minimum network configuration.
NOTE:
If the unit controller application software requires a
field update, the network configuration parameters
revert to their default values. Please contact the
Applied Air Handling Customer Support Group at
763-553-5330 for assistance with upgrading the unit
controller application.
