1 technical guide systems integration overview Integration between various control systems within projects, reduce end-users need to have multiple interactions to perform what seems like one task such as play DVD or arm security system. To perform this function, many different control system elements need to work together. By using different Philips Dynalite gateways, these elements can be coordinated together to produce a seamless performance. Philips Dynalite provides several different methods for interfacing with other services, such as building management systems (BMS), projector controllers and audio-visual controllers, blind motors and other third components. This guide outlines some examples of differing techniques. DyNet over RS485 All Philips Dynalite products communicate using the DyNet protocol which uses RS285 for communication. A subset of Dynet commands has been made available to anyone wishing to directly communicate with the Philips Dynalite system. Many AV controller, alarm system and BMS vendors also make available software drivers that can communicate directly with the Philips Dynalite system using DyNet messages. This allows the system to be operated as an open protocol. The drawing below illustrates connection of a BMS directly onto the DyNet bus. In this method, command direct from the BMS server can be sent to the lighting control system. To assist in the development of communications drivers for DyNet, we have developed an Integrator s Handbook, a copy of which is available on request from local Philips Dynalite dealers.

2 DyNet over RS232 DyNet message packets can also be sent and received over RS232 networks. The Philips Dynalite DTK unit is a passive network gateway that converts RS485 to RS232 for full duplex communication that allows AV systems that use RS232 to simply send Dynet commands directly. For more advanced integration that requires network message filtering or logical processing, the DMNG2322 gateway is ideal. This gateway has advanced features enabling it to receive custom RS232 data strings that can trigger a task or send a Dynet message on the RS485 port. An example of this is shown bellow. The device can also be used to send custom RS232 data strings to other third-party devices triggered from Dynet messages. This can allow third-party systems such as AV to be controlled from Philips Dynalite pushbutton panels. LonWorks The Philips Dynalite DDNI-LON provides a LON interface to the DyNet network, via a TP/FT1 LonWorks port. Lighting SNVTs (standard network variable type) are supported, as well as user-defined types. The device can typically translate up to 1 presets in 3 areas.

3 The diagram above illustrates the cascading of multiple DDNI-LON devices to accommodate a DyNet network with more than 3 areas. The device can also be used to trigger complex tasks for changing a project mode. For example, a BMS system manages the scheduled events and uses LON to communicate to the various systems throughout a project. A single LON message can be sent that can change the Philips Dynalite system to operate between after hour and trading hours mode. This can change the operation from panel function to sensor timer out, if required. BAnet BAnet integration allows for BMS system to send commands to the Philips Dynalite system triggering functions and timed events. In a Philips Dynalite system that is of a trunk and spur topology, the BAnet gateway can be connected directly to the network trunk giving it access to all of the system devices. The BAnet protocol uses addressable points for communication; these addressing points can be adjusted by the BMS for triggering required functions such as timed events or the Philips Dynalite system for reporting back current system status. An example of the kinds of functions that can be achieved is when the BMS system enters After hours mode, a request can then be sent to the Philips Dynalite lighting control system via the BAnet protocol to turn off all the lighting on a particular floor. The lighting control system can then flash the lighting off, warning any occupants still on the floor that they need to interact their continuing occupation of the area by pressing an afterhours button or the lighting control system could use passive presence detectors for detecting occupants. If no occupants have indicated their presence, then the Philips Dynalite control system will switch off the lighting and report this back to the BMS so that the aircondition plant can also be automatically shut down. This kind of integration allows for one system to control many different elements within an area. TP/IP Internet-Ethernet Ethernet connectivity Philips Dynalite supports a wide range of Ethernet gateways for different mounting requirements.

4 Using Ethernet gateways allows for networking multiple Dynet RS485 networks together or allows for integration to web-based systems. In a typical application of a high-rise office building, each floor will have its own Philips Dynalite system operating independent of each other. On each of the floors the network uses Dynet RS485 to communicate between the different devices. To coordinate the different floor systems together, each of the separate sub systems can be linked together via an Ethernet using gateways. A high speed Ethernet trunk is run between the floors of the building allowing for site-wide command to be sent while each of the floors use a network gateway to spur off and start the network. In applications where the distance between the Philips Dynalite devices exceeds the RS485 network limit, such as interconnecting separate buildings or linking control centres in a tunnel. These distances can be overcome by running fiber optic cables between the sites and having them connected together via Ethernet gateways. The Ethernet gateways also support the feature of providing remote control of a residential site via a web browser interface or Philip Dynalite DynamicTouch software. This remote control functionality can be made available from external locations by making the gateway visible on the Internet, as well as providing remote control within the dwelling via hand-held computing devices such as Palm Pilots, i- Pads and web tablets, via connection to a Wi-Fi hub. Ethernet connectivity products onnection of Philips Dynalite RS485 to the Ethernet is achieved using one of the Ethernet Gateways. It can be configured to use the TP/IP protocol and has an inbuilt web server that can be configured to serve up pages allowing control of the lighting control system via a web browser. EnvisionManager Server software is designed to provide high-level integration and control options to a DyNet network via Ethernet. The DyNet network is connected to a server P s OM or USB port and information can then be exchanged via client software running on the server P or clients connecting remotely over the Ethernet network using TP/IP.

5 Integration to other services is made simple by the use of a set of calls for an industry standard DOM interface. EnvisionManager can use client software such as Traypan which is an inexpensive solution for providing occupants of open plan office space with control over their local environment. TrayPan client software is provided with EnvisionManager and can provide control of the local lighting from the tool tray of desktop P s. It uses the existing LAN to communicate with EnvisionManger server software. When used for occupancy detection, additional cost benefits can be made from not having the provision of local control panels and sensors that would otherwise be required. A web page with an ActiveX control is another inexpensive option of client control. The optional EnvisionManager Toolbox Software Development Kit provides a rapid integration environment for connection to BMS. A set of system calls and example clients, including source code, are provided to assist with development of integration solutions and custom clients. As well as control and status reflection of the lighting system, alarm events such circuit breaker trips and lamp failures can be automatically forwarded to the BMS. Diagnostic and maintenance data such as lamp burn time is also readily available. infrared infrared reception Philips Dynalite sensors are multi-function devices; incorporating motion detection, light level measurement and infrared reception. Infrared signals from hand held remote controls are received by the sensors and can be translated into DyNet messages, which can then recall a lighting scene of trigger Philips Dynalite Technical Guide Systems Integration Page 5 of 9

6 a complex task. These messages can also be translated into other formats via network gateways, such as into ASII text strings via the DNG232 Network Gateway or back into infrared via the DIRTX8 Infrared Transmitter. Philips Dynalite offers a range of hand-held remote controls for use with the Philips Dynalite sensor range. The codes from these remote controls can be used to program most models of unified programmable or leaner remote controls. infrared transmission The DIRTX8 Infrared Transmitter is an 8-channel device, commonly used to integrate equipment with an IR port, such as AV controllers and airconditioners, onto the DyNet network. These IR transmissions can be triggered from any Philips Dynalite user interface such as a pushbutton panel or even a motion sensor. Multiple IR codes can be programmed to transmit with the press of one button by using the inbuilt task engine. A typical situation is where small IR emitters are fixed to the IR window of Hi-Fi equipment. The IR emitter includes a one-metre lead terminated with a 2.5mm plug, which is plugged into the DIRTX8. Multiple channels allow the DIRTX8 to transmit individual codes out on each channel, which eliminates problems where different Hi-Fi components share the same code. The DIRTX8 can record and store macros that are executed in response to DyNet messages on the RS485 network. analogue and dry contact inputs For receiving analogue and dry contract inputs, the DDMID8 unit meets the integration requirements. The unit can receive eight dry contact inputs and four analogue inputs. When a dry contact closure is detected, the unit can perform a wide variety of functions such as recall a scene or perform a control room join. As the unit also has a task engine, multiple functions can be performed from a single contact closure. The unit can also receive 1-1V analogue input and directly translated this into Dynet channel level messages. Both styles of inputs can be used at the same time so that when a contact closure is detected the analogue inputs are then enabled. This kind of function could allow a user who wants to use a single rotary pot to control very large lighting loads that could not normally be controlled in such a format. dry contact outputs Philips Dynalite offers several dry contact units that can be used for interfaces, as well as load control. Two of the more common models comprise eight sets of changeover contacts for added flexibility; the DDR81DT-GL (DIN rail mount) and the DR81DT (wall mount). These outputs are suitable for connection to SELV circuits. Page 6 of 9 Philips Dynalite Technical Guide Systems Integration

Supply: 23V.5A 1 Phase E N L GND D + D - +15V AUX µp DMX512 dual port load controllers Many Philips Dynalite load controllers are available with dual ports, which allow a separate control network for DMX512 signals, while still allowing the use of the main control system. The DyNet network can be used to control the behavior of the system in response to DMX signals, such as the selection of the circuits for which DMX512 control is allowed. It is also possible to only allow partial control of a circuit via DMX512, in the form of setting a low limit, which is useful for allowing partial control of critical circuits such as egress lighting, but never allowing these circuits to be switched off or dimmed to an unacceptably low level.

8 The diagram above illustrates the use of dual port load controllers. converting Dynet to DMX512 A common requirement for buildings such as hotels, museums and other sites with a lighting control system is to connect outdoor architectural lighting to the Philips Dynalite network. Often this style of fixture operates on DMX512 communication protocol. The Philips Dynalite DNG485 Network Bridge converts DyNet into 64xchannels of DMX512 signals. converting DMX512 to Dynet DMX512 can also be converted into DyNet channel level messages. This would be typically be achieved by connecting a theatrical lighting desk onto a DyNet network gateway DNG232, removing the need for the lighting control devices to be double ported for DMX512, apart from a single interface. This method Page 8 of 9 Philips Dynalite Technical Guide Systems Integration
