Features of the BGW
 Web interface configuration
 Automatic detection of modules
 Automatic detection of Remote Units
 Can handle large systems
 Functions for statistics
 Northbound communication to CGW
 Includes firewall to protect local net
 Is the portal to your Master Unit
 User-provided certificate based security via HTTPS
If the BGW is replaced the Remote Units
may not show up immediately. This is due
to the lease time on the address they have.
Eventually they will request a new address
and when this is done they will show up.
The BGW is the unit responsible for alarm
handling and remote forward of alarms
either by SMTP mail forwarding or by
SNMP traps. A MIB file for your SNMP
system is available from DeltaNode upon
request as well as documentation
regarding SNMP.
The BGW can also launch VPN tunnels to a remote supervision center called the Central Gateway (CGW).
This way it is possible to manage multiple systems from a single place. The CGW will be described later in
this manual.
The BGW has two Ethernet ports. One is connected to the internal network in the Master Unit to provide
the local network for all the modules, the Remote Units and everything else. It also provides, via the
built-in switch in the Master Unit, a way of locally configuring the network. It provides the web interface
for all the settings of the system as well as many other functions. Secondly there is a “northbound”
Ethernet port that allows the BGW to connect to the Internet, or a WAN/MAN type of larger network.
This means that the system can be monitored and managed remotely.
A Virtual Private Network (VPN) tunnel can be set up from the BGW to a central location using a CGW.
The CGW can handle a large number of such tunnels, providing a central point for supervising all the
installations and collecting alarms and statistics from all the systems as well as centralized alarm
management. The BGW can actually set up a second tunnel, which is sometimed done to DeltaNode
management center where we can help with management and supervision. This is a service that we
provide if needed.
The actual use and how to set up the BGW will be described in the commissioning and supervistion and
maintenance chapters of this manual.

A BGW can also be set up in factory for a special need, it will then be delivered together with a restore
image that allows the customer to restore it quickly in case of a hardware failure.
