C-Bus/BACnet Gateway

Gateway Configuration

Before you can use the gateway, you need to configure some specific parameters. The configuration runs via a standard web browser.

Use the following parameters for the first login :

URL     :  http://192.168.1.222:8080
Username:  cbox
Password:  manager

After successful login, you need to perform some configuration tasks. Go through the preferences menu and update all the parameters that apply to your site. At the very least, you must check the gateway address and bus speed (baud rate) on the C-Bus to avoid address collisions and bus failures. And of course, you should change the default password!

Platform Settings

Go to the Preferences -> Platform menu and update the gateway platform properties according to your needs.

Property	Description
IP Address	Gateway IP address
IP Mask	Gateway IP mask
Default Gateway	Default IP gateway
Web Server Port	IP port for the intergated web server
Use NTP to Sync Time	True if you are going to sync the local date and time from the internet
Date / Time	Current date and time. Readonly if NTP is on
Timezone	Timezone of the gateway
Commissioning	If true, only limited set of C-Bus interactions is available

Save the changes with the Save button.

Commissioning checkbox switches the gateway between two modes. If true, the gateway does not activate the main polling loop and does not query for any C-Bus information like point values. In the commissioning mode, only the device and point learning are available actions on the C-Bus. You should not remove the flag commissioning until the gateway is fully set up. The setup includes the discovery of devices and data points, configuring their mapping to BACnet, including configuring attributes if you also plan to map them to BACnet.

C-Bus Settings

Go to Preferences -> C-Bus menu and update the gateway C-Bus properties according to your needs. The most important option is the gateway C-Bus address, that must be unique on the bus, and the C-Bus speed (baud rate). Additionally to the C-Bus options, you can later perform commissioning actions here. For more details about the action buttons, please see the chapter Utilities.

Property	Description
C-Bus Name	Gateway name on the C-Bus
C-Bus Address	Gateway unique address on the C-Bus
C-Bus Baud Rate	C-Bus baud rate
Map C-Bus Attributes	Check if you are going to map additional point attributes
Device Point Prefix	Name prefix for BACnet objects monitoring the status of the C-Bus controllers. For more details see the section `Device Points` under `Point Manager`

Please read carefully the documentation about additional attributes mapping before you activate the Map C-Bus Attributes option!

Please do not change the other settings in the C-Bus property sheet. These are the parameters that affect the behaviour of the C-Bus and should be changed only on the recommendation of the technical support.

Save the changes with the Save button.

BACnet Settings

Go to the Preferences -> BACnet menu and update the BACnet server properties according to your needs.

Property	Description
BACnet Device Name	BACnet device name
Bacnet Device Description	BACnet device descriptor
BACnet device ID	BACnet device ID on the BACnet network
BACnet Network Number	Number of the BACnet network
BACnet IP Address	Gateway IP address, readonly
BACnet Port	BACnet server IP port
BACnet Broadcast Address	BACnet broadcast IP address
BACnet Write Priority	Priority level for value write command (default 8)
BACnet Alarm Recipients	List of clients receiving C-Bus alarms

Save the changes with the Save button.

The BACnet server IP address in the form is readonly, all other properties are writable. Changing the IP address in the Platform menu automatically updates the BACnet broadcast address as the latest address of the IP segment.

The gateway sends C-Bus alarms to the BACnet recipients as BACnet Alert Notifications. There is only one Alert Enrollment object in the gateway, and if no alarm recipient is defined, all alerts are sent as broadcasts. Add a list of recipients in the field BACnet Alarm Recipients to ensure the C-Bus alarms will reach all your clients. Add an alarm recipient in the form ipaddress:port, e.g. 192.168.130.17:47808.

Check the settings

Open the Home menu and check the status of the C-Bus and BACnet services. Assuming the C-Bus is physically connected, you should see the proper status of both components.
