Restrict access to the (BACnet) IP network to an authorized group of people through user IDs and strong
passwords.
Additionally secure remote access to the device via a VPN connection.
A virtual private network (VPN) establishes an encrypted and authorized connection (VPN tunnel) from a
remote location to a network over the Internet. This VPN connection allows for a secure
and overheard-protected communication between a remote device and the KNX installation.
If Wi-Fi is used, change the default SSID from the wireless access point. Encrypt the Wi-Fi with a secure
procedure (currently e.B. WPA2) and a strong password.
Document network settings and hand them over to the building owner/operator or the LAN administrator.
Manage access rights to this BACnet device on an IP network with the appropriate IP network administrator.
Since the DCC (DeviceCommunicationControl) password is stored in the device, the ETS BCU password must
be set to protect this password.
For security reasons, the FTP port may only be opened for a firmware download and must be closed again
after the update.
For security reasons, the HTTP port may only be opened during troubleshooting and commissioning and
must then be closed again.
The configuration of the device must be backed up. To do this, an ETS BCU password must be set and
KNXnet/IP must be deactivated.
Actions after replacing a device on the network
If a BACNET gateway is stolen from a network or replaced due to a defect, the BACnet DCC (DeviceCommuni-
cationControl) password must be changed and a different BAU password must be assigned to the new BACnet
gateway.
This is necessary because it cannot be ruled out that the passwords that are in a protected area of the device
can be read.
Installation notes
The device may be used for permanent interior installations in dry locations within distribution boards or small
casings with DIN rail EN 60715-TH35.
