Key Features
The J1-LED MIDAS Outstation Intelligent Vehicle Detector is a reliable and accurate vehicle detection system.
The MIDAS Outstation collects, stores, and reports on multi-lane traffic data comprising individual vehicle data events or average flow data on traffic volume, speed, length category, vehicle headway, and percentage occupancy. It can monitor 20 loops (10 lanes) at vehicle speeds up to 125mph.
The MIDAS Outstation supports communication via RS485 interfaces for legacy installations and IP-based interfaces for new deployments. The Outstation is compatible with NMSC2 protocols.
Remote access via RMAS interface allowing for rapid configuration, real-time incident detection, real-time viewing of traffic and host communication data, extensive fault diagnostics and logs.

The MIDAS uses the already proven TD664 detector incorporating Automatic Frequency Selection (AFS). The AFS circuitry on each 4-channel card evaluates 21 possible frequency shift selections and automatically chooses the best frequency setting on start-up.
The MIDAS logs every event that occurs and classifies it as a vehicle event, communications event, fault, alarm, debug, info, or critical issue. This data is available on a real time Live View via the web interface. The data is also written to file and can be stored in onboard Flash memory downloadable locally via the Engineers Terminal interface or via a remote access service such as RMAS.
Traffic data comprises average data calculated over pre-determined intervals and includes vehicle count, speed, volume, headway, and occupancy. Optionally individual vehicle reporting can be selected which provides a record of every vehicle showing its lane number, speed, length, and headway. Loops can be configured as stand- alone loops or paired into lanes to suit the application and required data.
The MIDAS has an Ethernet port for Upstream connectivity using the MIDAS NMCS2 protocol. A second Ethernet port can be used for on-site Engineers Terminal access. The Engineers terminal and supporting Debug features allows equipment interrogation, verification and setup of all operating parameters, real-time monitoring of traffic data and communications, and viewing and downloading of traffic data and logs.
Two serial ports are provided to support the MIDAS Transponder connection and the Outstation Auxiliary Link.
