Naztec 2070N ITS Controller

Download a Product Sheet for the 2070

Naztec is happy to present the 2070N advanced traffic CU (Controller Unit) which meets and exceeds current CALTRANS specifications.  The hardware is built on the Motorola VME platform which provides an open data buss that accepts interface cards from a number of sources.  The software developed by Naztec, Inc. supports the OS-9 operating system called for in the CALTRANS specification.

The 2070N bridges the gap between NEMA TS-2 and CALTRANS 170E controllers by providing full I/O capability with NEMA using the TS-1 "A", "B", "C" and "D" connectors and with Type 170E cabinets using I/O connectors defined in the CALTRANS specifications.  The NTCIP protocol insures that the 2070N is fully compatible with ATMS applications at the communications level.

In addition, Naztec is partnering with Cisco to provide WAN applications using Cisco's routers to interconnect signals on fiber networks using TCP/IP protocols to take NTCIP where it was intended to go.

The CALTRANS 2070N specification defines the hardware and operating system for the CU and provides a high end platform to develop software applications for ITS.  Naztec software developers are pushing the envelope with this new technology by providing a 4-ring, 16-phase, 16-overlap controller with many new features and improvements over the old NEMA and 170E.  A sample software specification is available for download to provide a sample of the software capability being developed for the 2070N.  Some of these software features are summarized below:

Features

• Direct replacement for 170 CU

• Compliant with CALTRANS 2070N specifications
