NTester is a tool that allows an individual unfamiliar with technical details of the National Transportation Communications for ITS Protocol (NTCIP) to test devices for NTCIP conformance. Version 2.4 includes:
- A set of built-in automated test procedures for:
- DMS
- ESS
- CCTV
- Supports manual testing through a MIB browser,
- Supports SNMP and STMP
- Supports UDP/IP, TCP/IP, and TTP/PMPP
- Provides a TestDeveloper tool to allow users to easily develop their own test suites (requires interaction with Trevilon) and
- Allows users to write or record their own macros using Microsofts Visual Basic for Applications
While it is designed so that a novice can use it, the software provides NTCIP-experts and manufacturers an automated way to perform rigorous testing in a repeatable fashion. For purchasing information, contact kvaughn@trevilon.com.

FTS for NTCIP
FTS for NTCIP is a protocol analyzer jointly developed by Frontline Test Equipment, Inc. and Trevilon for monitoring and analyzing NTCIP data communication protocols associated with Intelligent Transportation Systems (ITS). It operates on both serial (RS-232/422/485/530) and Ethernet networks. Currently supported protocols include PMPP-232, PMPP-FSK, PPP-232, and Ethernet (NTCIP Subnet Level); T2 (Null) and Internet (UDP/IP and TCP/IP) [NTCIP Transport Level]; SNMP and STMP (NTCIP Application Level); and Global, ASC, DMS, and ESS (NTCIP Information Level). FTS for NTCIP also compiles any MIB to recognize new data objects as needed.The new version of this software enhances the decoding of NTCIP packets, provides the ability to bookmark frames, and includes decoding of NTCIP traps according to their draft definition in NTCIP standards.
NOTE: This is now sold as three distinct products. You will need to purchase the NTCIP Decoder along with Serialtest or Ethertest.

Users of Serialtest may also find it useful to be able to add serial ports to their computer. We also sell PCMCIA cards that work with Serialtest.
TestDeveloper
TestDeveloper is a tool to assist in the creation of test procedures that conform to the NTCIP 8007 format. The tool allows users to enter a structured set of requirements and to trace each requirement to one or more test procedures. Each test procedure can then be defined through a series of structured test steps. Each test step has a step type and associated information that is relevant to the type. For example, a GET command is associated with the list of objects that should be retrieved and the type of error response expected.TestDeveloper stores its information in an open XML format according to a published schema. It can also generate a report that conforms to the NTCIP 8007 format (e.g., to include in an NTCIP standard or to publish as a set of agency-specific procedures) and generate C++ code that can be provided back to Trevilon for inclusion into the next release of our software. Of course, any other tool manufacturer is also free to translate the XML file into its own programming language if they wish.
Currently, this software is available as a beta release and is distributed with NTester for free. If you wish to become a beta tester and do not own a current license of NTester, please contact kvaughn@trevilon.com.
The original version of NTester is still available for free download. Version 1.3 provides automated tests for version 1 Dynamic Messages Signs (DMS), Environmental Sensor Station (ESS), and Closed Caption Television Camera Control (CCTV). This version of the software was released as freeware under an agreement reached with ENTERPRISE, the I-95 Corridor Coalition, and the Federal Highway Administration. This version does not include Visual Basic for Applications integration, MIB browsing capability, STMP support or detailed information about the steps being performed.
