1Introduction
1.1 SPC Bridge KNX
SPC Bridge
Weinzierl KNX interface 332
Weinzierl KNX interface 312
SPC Bridge KNX allows interfacing Vanderbilt SPC intrusion system to a KNX system. Using the SPC
Bridge you are able to use events from all your SPC connected motion detectors, door/window
contacts, fire detectors and alarm status for automations in your KNX system. SPC Bridge KNX
includes a certified Weinzierl KNX interface (332 or 312) for a reliable and approved connection to
the KNX bus.
1.2 Main Features
Mirrors SPC zone and area states/status to KNX bus
Support for area and zone commands from KNX bus, e.g arm/disarm, inhibit zone.
SPC Panel Communication using FlexC
Weinzierl KNX interface 332 or 312
Communication objects configurable in KNX ETS.
Web based Admin GUI
Recommended for maximum 128 zones and 16 areas (The actual limit depends on the use case,
e.g. how many motion detectors the SPC system has.)

2Installation
2.1 Prerequisites
Vanderbilt SPC panel with firmware >= 3.6 (3.6 was the first version with support for FlexC)
Network router with DHCP server enabled
SPC Bridge and SPC panel connected to same local network
Internet access (to be able to use time synchronization via NTP)
KNX system
KNX configuration tool ETS v 5
2.2 First Time Installation Workflow
1. Read carefully End-User License Agreement for SPC Bridge (EULA) in last section in this document. If
you do not agree to the terms of the EULA, do not install or use the SPC Bridge.
2. Connect the included KNX interface, Weinzierl 332 or 312, to the SPC Bridge USB port.
3. Connect the KNX bus cable to the KNX bus connector on the KNX interface. NOTE! The default
individual device address of the KNX interface is 15.15.255. If this address already is in use you should
change the address (see section KNX Interface Info) before you connect the interface to the KNX-bus.
4. Connect the SPC Bridge LAN port, with a regular network cable, to your network switch or router.
5. Power up the device by connecting the included power adapter to a wall socket and then to the SPC
Bridge.
6. Wait (~3 minutes) until the SPC Bridge has fully started.
7. Open a web browser and access your router (DHCP-server) to find the IP address assigned to the SPC
Bridge. Type the IP address in the web browser to go to the SPC Bridge sign in page.
8. Assign a static IP address to the SPC Bridge. Follow instructions in section System Administration,
Static IP Address.
9. Configure SPC communication. Follow the instructions in section SPC Bridge Configuration, SPC
Communication.
10. Test the SPC Communication. See SPC Communication Test.
11. Configure the KNX interface. Follow the instructions in ETS KNX configuration

3System Administration
The SPC Bridge is based on a standard Linux platform, OpenWrt, that is very common on routers. The
System Administration Web GUI contains many settings intended only for advanced users. Only the
settings described in this section should be changed by normal users.
3.1 System Administration Login
Type IP address of the SPC Bridge in the web browser address field, go to SPC Bridge sign in page and
click on System Administration in the top bar.
This will open the OpenWRT sign in page. Enter username (root) and password (default: dragino) and
click on Login.
NOTE! To return to SPC Bridge sign in page you need to type the SPC Bridge IP address in the web
browser address field.

3.2 Static IP Address
Default will SPC Bridge use DHCP to get an IP Address. To be sure that the SPC Bridge keeps the IP
address after a network/router restart you should assign the SPC Bridge a static IP Address. In the
System Administration GUI, go to Network -> Interfaces and:
1. Select LAN –Edit.
2. In Interfaces –LAN, select Static address in the Protocol option menu
3. Click on Switch Protocol
4. In Common Configuration –General Setup fill in; IPv4 address, netmask, gateway and custom DNS
servers.
5. In DHCP Server –General Setup; check the checkbox Ignore interface. NOTE! It is very important to
disable the DHCP server in the SPC Bridge to avoid conflict with your normal DHCP server.
6. Click on Save & Apply.
7. Redirect your browser to the new IP Address.
3.3 Time Setting
To set correct Timezone, go to System -> System and select Timezone in section System Properties –
General Settings.
The device is as default using NTP to synchronize time. This setting is in System -> System section
Time Synchronization.
3.4 Change Administration Password
The default administration password for accessing the device is dragino. Of security reasons it is
highly recommended to change the password as soon as possible. Go to System -> Administration
section Device Password to change the password. The same password is used in both Administration
Web GUI and for ssh access to the device.
NOTE! The device has no RTC clock. During boot the device can have incorrect time. Some events
in the system log can therefore have incorrect timestamps.

4.1 SPC Bridge Sign In
Type IP address of the SPC Bridge in the web browser address field, go to SPC Bridge sign in page,
enter username (spcbridge) and password (default Spcbridge!) and click Login.
4.2 SPC Communication (FlexC)
To setup the communication link between SPC Panel and SPC Bridge you have to configure the link in
both SPC Panel and SPC Bridge ends.
4.2.1 SPC Panel - FlexC Settings.
Use Vanderbilt SPC Web interface and define the FlexC communication following this instructions:
1. Select Full Engineer mode
2. Create a specific user for the SPC Bridge communication, e.g spcbridge. User profile should be
Manager and you need also to define a web password for the user. (To be able to set a web password
you need to login as the user in the SPC web interface).
3. Select Communications -> FlexC -> Event Profiles. Click on Add to add a new event profile. Give the
event profile the name SPC Bridge Events and select (check) the report checkboxes for all event
types. (You may consider reducing these settings later to just necessary events for the application)
4. Select Communications -> FlexC -> FlexC ATS. Select Add Custom ATS and change following from
the default settings:
- ATS Name = SPC Bridge
- Event Profile = SPC Bridge Events (created in step 3)
- ATS Polling Timeout = 60 seconds
- Uncheck Generate FTC and Re-queue Events

(Scene Control Output), each time the assigned event occurs. The scene numbers are configured per
alarm area and can have values between 1 to 64 (Set 0 will disable the event).
An individual scene number can be assigned to following SPC events:
Area becomes unset
Area becomes partset A
Area becomes partset B
Area becomes fullset
Area reports an intrusion alarm
Area reports a fire alarm
Area reports a tamper alarm
Area reports a confirmed alarm
Area reports all alarms are restored

5ETS KNX Configuration
5.1 First Time Configuration
To configure the KNX interface you should use the KNX standard configuration tool ETS. The
configuration is based on a generic product database from Weinzierl, but adapted according to the
Communication Objects below. For a quick start please copy and paste the configuration from one of
the attached ETS project templates:
1. On ETS project page, import the template project file that best match your size of SPC
system.
2. Open the template project. In the Topology tree, select and copy the item 1.1.1 SPC KNX
SPC Bridge.
3. Switch to your ordinary project and paste the copied item to the Topology tree (see
example below).
4. Change the individual address to desired address of the KNX interface.
5. Download (full) configuration to the KNX interface. NOTE! To set the KNX interface in
programming mode you need to use SPC Bridge Web GUI, see section KNX Interface Info
(Programming Mode).
After successful first time configuration you can link the communication objects (datapoints) to
group addresses as usual.
5.2 Communication Objects
5.2.1 KNX Datapoint Map
States, status and commands from /to the SPC system are mapped to predefined datapoints/group
objects on the KNX interface. The datapoint map has following main structure:
