2 Nabla Quadro S.r.l. Sky Light Interface Card 868 General specification The Sky Light Interface Card 868 integrates the features of our Sky Light Hub and of a 16 channel dry contact card. In this way the events collected from Sky Light Sensor (Traffic version) trigger the activation of dry contacts exactly as inductive loops. Results can be output on 2 different types of serial interfaces: RS232 RS485 and on 16 ON/OFF optically isolated dry contacts, in order to emulate traffic detection loops. Pagina 2 di 5

3 A DC/DC Converter directly allows system to be powered from any DC source ranging from 10 V to 26 V. Furthermore the Card has an input for photovoltaic panel and an integrated NI- MH battery charger. Technical Specification The Interface Card has 16 optically isolated dry contacts. Channels are independent from each other and are referred to by number (1 to 16). Any detection event generated by one sensor in the network causes a transition on the corresponding contact. Contact Actions ( Open on Event or Close on Event ) may be individually configured by software. Furthermore, a set of sensors may be associated to an auxiliary Output that react to a combination of Events (For example an Or Logic can be implemented) Two channels are available for diagnostics (sensor failure and power supply down) The firmware of "Sky Light Interface card 868" provides the following features: Receiving and decoding of messages from sensors (Hub features) Synchronization of deferred messages due to sensor latency Recovery of slippage of the system clock Cancelation of too short events Implementation of policies to associate many sensors in OR logic in order to create a virtual magnetic loops of wider dimension. Power can be supplied through an external voltage between 10 and 26 VDC. Total energy consumption is around 60 ma (Including Hub features). Optional Features An Access Point (Traffic Version) can be optionally connected through the UART port (to send digital data directly on a server via Ethernet or GPRS). Pagina 3 di 5

4 A Radio-modem can be optionally connected by dedicate connector. The Radiomodem allows the Card to forward data to another Card (Repeater feature). Sensors configuration is available through RS232 port and dedicated software (Sky Light configurator). Pagina 4 di 5
