1Introduction
1.1 SPC Bridge KNX (gen 2)
SPC Bridge KNX (gen 2) 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
•Local network communication based on Vanderbilt’s official IP protocol FlexC.
•Direct connection to KNX-bus using Weinzierl KNX interface 332 or 312. The standard KNX tool ETS is
used for the configuration.
•Provides status and states of SPC areas, zones, outputs and doors.
•Support for commands to control SPC areas, zones, outputs and doors. e.g. arm/disarm, inhibit zones
and set outputs. The commands allowed are determined by the SPC panel's settings.
•Web based Admin GUI.
•Versatile tools for troubleshooting.
•Technically, a maximum of 256 zones, 16 areas, 8 doors and 16 outputs (mapping gates) are supported.
However, in practice, it is advisable not to exceed more than 128 izones to ensure optimal performance.
1.3 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

2Getting Started
2.1 EULA Agreement
Read carefully End-User License Agreement for SPC Bridge (EULA) in section 9.3 in this document. If you do
not agree to the terms of the EULA, do not install or use the SPC Bridge.
2.2 Install the KNX Interface
Connect the included KNX interface, Weinzierl 332 or 312, to the SPC Bridge USB port. Connect the
KNX bus cable to the KNX bus connector on the KNX interface. Please 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 4.3.1) before you physically connect the interface to the KNX-bus.
2.3 Ethernet Connection
Default network protocol is DHCP. Connect the SPC Bridge LAN port, with a regular network cable (included), to
your network switch or router.
2.4 Power On
Connect the power adapter to the SPC Bridge using the included power cable. Plug the power
adapter into a wall outlet.
2.5 Access the Web Admin GUI
Wait (~3 minutes) until the SPC Bridge has started up. Get the Device ID (7 characters) from the back
of your SPC Bridge device.
To visit the Login page, open a web browser (we recommend Chrome) and go to:
http://SPC-BRIDGE-DEVICE_ID.local
Example: If your device has ID aj4c5ab you should give the url: http://SPC-BRIDGE-aj4c5ab.local
Please note, if the url http://SPC-BRIDGE-<Device ID>.local isn’t working you can check your
router for the IP address of the SPC Bridge and use the url http://SPC_BRIDGE_IP instead.
Please note, for security reasons, all default values should be changed to your own.

2.6 Assign a Static IP Address
As default the network protocol is DHCP, but it is recommended to assign a static IP address to the
SPC Bridge. Follow the instructions in section Basic System Administration, Network (section 3.1) to
set a static IP address.
2.7 Setup Communication with the SPC Panel
Configure the FlexC communication to the SPC Panel by following the instructions in section
Configuration, SPC Communication (section 4.1) .
2.8 KNX ETS Configuration
Add the SPC Bridge KNX to your ETS project by following the instructions in section Configuration,
ETS KNX configuration (section 5).
2.9 SPC Bridge Security Hardening
For reasonable security you should always change the default settings for:
•Web GUI user password. (System > Web GUI –Login User).
•SSH user password. (System > SSH)
•FlexC encryption key and user credentials. (Services > SPC > FlexC).
In sensitive environments, it may also be wise to enhance security further by:
•Only allow HTTPS when accessing the Web GUI (see section 6.3).
•Only allow key-based authentication for SSH access (see section 6.1).

3Basic System Administration
3.1 Network
As default the SPC Bridge uses DHCP to obtain an IP Address. To ensure that the Bridge retains the
same IP address on the LAN port, for example, after the router has been restarted, the Bridge should
be assigned a static IP address. You change the LAN settings in System > Network. Uncheck Enable
DHCP to set a static IP and check/alter all the other network settings before saving.
The settings will take effect immediately when you Save & Apply and have acknowledged the
warning message. You have to manually redirect your browser if you have changed the IP address.
Please note, the WAN port should only be used as a last resort if you are unable to connect to the
LAN port. The WAN port always uses DHCP and cannot be changed via the WEB GUI.

3.2 Time
In System > Time you can change the time zone, sync the time with the current time of your browser
and also configure the NTP (Network Time Protocol) service.
3.3 Web GUI
In System > Web GUI, you can change the password for the Web GUI login user. The username is not
changeable, it is always spcbridge.
Please note, the device has no RTC clock. During boot the Bridge can have incorrect time. Events
that occur before the Bridge has received the current time via NTP can therefore have incorrect
timestamps.

4.1 SPC Communication (FlexC)
SPC Bridge is using Vanderbilt’s official IP protocol FlexC to communicate with the SPC Panel. The
communication is entirely local with no dependency on any cloud service. The communication is
initialized by the SPC Panel. The Bridge acts as a FlexC client, RCT.
To set up the communication, it's easiest to first configure the SPC Panel and then the SPC Bridge.
4.1.1 Setup FlexC Communication in the SPC Panel.
Log in locally to the SPC Panel using SPC's web interface and follow the following 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.
Note! The username must be 4 to 16 characters and the password 6 to 16 characters. Username and
password may only include following characters: a-z A-Z 0-9 . ! @ # $ % _ + - = ; < > ?
Hint! To set a web password for a new user in SPC you need to login as the specific user first, using
the pin code and go to Configuration -> Change Own Pin -> Change Web Password
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 third-party
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
5. Select Add ATP to FlexC RCT and change following from the default settings:
- SPT Account Code = 999
- RCT URL or IP Address = IP Address of the SPC Bridge
- ATP Category = Cat 6 [Ethernet]
6. Open Advanced ATP Settings and change following from the default settings:
- Encryption Key Mode = Fixed Encryption
- Encryption key (64 hex digits) = Your own key (This key should be copied to the SPC Bridge)
Please note, in Full Engineer mode, the panel does not report any events to the bridge, so it's very
important to be logged out of Engineer mode during communication tests.
