INSTALLATION RADAR INSTALLATION - RED LIGHT ENFORCEMENT (RECEDING FLOW) The nature of the design of the radar lends itself to versatility in its mounting on the roadway. There are however, factors to be considered when siting the radar to ensure optimum performance is achieved. 20º The radar should be installed at an angle of approximately 20º from the pavement line and sited toward the centre of the junction area. The area to be enforced should be within the ‘D1’ range of the radar (85 metres max).
INSTALLATION RADAR INSTALLATION - RED LIGHT ENFORCEMENT (RECEDING FLOW) This diagram shows the potential beam coverage of the 350 Radar being used to monitor an intersection for red light enforcement. The ‘D4’ distance is an important consideration when adjusting mounting parameters of the radar. Adjusting mounting height, offset and mounting angle will all have the effect of increasing or decreasing the ‘D4’ value. The value is defined as the initial point of radar coverage on the surface of the roadway.

INSTALLATION RADAR MOUNTING As highlighted on the previous page(s). There is a certain amount of flexibility in the position of where the RADAR is mounted. The offset, height, distance from stop line, even orientation in relation to the stop line can be altered, however when selecting a mounting position, all parameters should be reviewed to ensure that sufficient RADAR beam coverage of the area of interest, can be achieved at the chosen mounting location.

SYSTEM HARDWARE OVERVIEW RS422 SERIAL INTERFACE A UART interface is provided that uses RS422 voltage levels on the multi-pin mating connector. The default baud rate for this interface is 921600. The serial interface default set-up, during normal operation is shown in the table below.
SYSTEM HARDWARE OVERVIEW ETHERNET INTERFACE An optional Cat 6 Ethernet interface is provided on product connector 2. The 350 radar requires it be connected to a network and be able to obtain an IP address through a DHCP server. A Cat 6 interface cable is not provided for use with the product, but should it be fitted, it should be of the type: Overall braid screened, shielded twisted pair (S/FTP). This is to ensure EMC compliance.
SYSTEM HARDWARE OVERVIEW POWER SUPPLY The radar is powered using a DC voltage in the range of 10-16 Volts. The power is applied to the radar using the multi-pin mating connector. Reverse polarity protection is included in the design. The radar takes approximately 1A for a period of 5ms. The radar consumes 500mA at 12vDC. Power consumption is approximately 6 Watts. A thermal fuse with a 1.25A rating has been installed to protect against electrical short circuit fault conditions.

RADAR COMMANDS RADAR COMMAND OVERVIEW Commands are used to control the operation of radar. These can be sent over the RS422 UART Link. (Ethernet available at a later date) Commands are immediately followed by an operator that indicates the required action. Not all the operators are supported for all commands. Where an operator is used and it is not supported the radar will respond with warning message. The table shows the commands used by the radar. Operator Operation = Set a parameter to a value e.g.

IMPORTANT SAFETY PRECAUTIONS All work must be performed in accordance with company working practices, in-line with adequate risk assessments. Only skilled and instructed persons should carry out work with the product. Experience and safety procedures in the following areas may be relevant: • Working with mains power • Working with modern electronic/electrical equipment • Working at height • Working at the roadside or highways 1.
IMPORTANT IMPORTANT INFORMATION Low Power Non-Ionising Radio Transmission and Safety Concern has been expressed in some quarters that low power radio frequency transmission may constitute a health hazard. The transmission characteristics of low power radio devices is a highly regulated environment for the assurance of safe use. There are strict limits on continuous emission power levels and these are reflected in the testing specifications that the products are approved to.
