2198 Westermo's DDW-120 Ethernet extender allows existing twisted pair cables to be used to establish a high-speed remote connection between two Ethernet networks. The company claims this is an easy-to-install alternative to optic-fibre or radio systems when linking remote Ethernet networks.

The device employs a transient blocking unit on each line interface to provide both over-current and over-voltage protection, allowing the line to handle indirect lightning strike transients, power induction and short circuit problems.

The DDW-120 uses twisted pair cables rather than expensive optical fibres or radio links. This plug-and-play unit covers many applications, offering data rates from 192Kbit/s to 5.7Mbit/s in both directions over distances of up to 15km (10 miles).

    A new report carried out by Parsons Brinckerhoff on behalf of the DC Department of Transportation (DDOT) finds that speed cameras are helping to reduce accidents and injuries and slowing drivers down. The DDOT conducted an engineering study to determine a link between traffic safety and placement of automated speed enforcement devices (speed cameras) in the District of Columbia. As part of this study, Parsons Brinckerhoff and its team members conducted speed and volume studies, carried out field assessme

    Self-employed courier or taxi drivers who get their work through apps could be more likely to be involved in a collision, says a new study. The University College London (UCL) research found 63% of ‘gig’ economy respondents – who are not paid a salary - are not provided with safety training about managing risks on the road. The emerging issues for management of occupational road risk in a changing economy: A survey of gig economy drivers, riders and their managers also revealed 65% of drivers did not
