Meeting NEMA TS2 Requirements for Traffic Control ApplicationsConnectivity and Communication Solutions Designed for Traffic Control Assemblies

NEMA TS2 Environmental Requirements

• Meet or exceed -34°C to +74°C temperature range

• Meet or exceed 18% to 95% humidity over the temperature range

• Meet or exceed vibration: 0.5g @ 5 to 30Hz

• Meet or exceed shock:10g

The National Electrical Manufacturers Association (NEMA) TS2 is a standard for traffi c control assemblies, such as traffi c lights, emergency road condition signs and walk/don’t walk signs.

The standard is designed for manufacturers to meet or exceed a set of minimum requirements to ensure high network reliability in Intelligent Transportation Systems (ITS). Many ITS applications share the following characteristics: remote, outdoor enclosures; equipment that needs to support a wide temperature range; equipment that needs to survive a wide humidity range; and solutions that often have a combination of several different communication technologies.

Advantech has tested products to meet or exceed the environmental aspects of the NEMA TS2 standard. The Advantech product range covers traffi c control cabinet applications that require Ethernet Switches, Fiber Media Converters, Serial Isolators, Ethernet Extenders, Ethernet Routers and Wireless communications equipment.

Traffic Control SolutionsTraffic Light ControlSeveral data communication products can help with traffi c light control, such as copper extenders or fi ber media converters. These devices are used to connect one traffi c control cabinet to another traffi c control cabinet. Ethernet extenders can be used for installations where wires already exist. For new installs or where fi ber can be pulled to use, fi ber is the best option. Many controllers still have a serial interface and can utilize IP or Ethernet to enable the traffi c controller for remote monitoring. Serial servers can be used for fi eld service, setup, and diagnostics.

Roadside Radar ApplicationsRoadside radar signs are usually mounted to a pole on the side of the roadway, or on a small mobile trailer. Radar data is sent when it’s needed to update information sent to digital signs or needed to dispatch law enforcement. When data is sent, managed Ethernet switches with fi ber ring technology are used at the network backbone. For remote or temporary locations, cellular routers may be used. Serial servers are used to enable the radar detection devices with Ethernet connectivity, and serial isolators are used to protect remotely-mounted radar equipment in extreme weather conditions. Devices used in these applications must meet a wide temperature range of -34°C to +74°C, and be shock and vibration tested.

Roadside Digital Signage For digital signage, the larger network will consist of managed Ethernet switches connected to a serial server, or to a fiber media converter that connects to the serial server. Serial servers are used to convert the Ethernet signals to serial signals. If needed, serial isolators or serial to fiber modules are ideal for isolating and protecting devices.

What To Use:

• IMC Media Converter (IMC-350I-SE-A)• EKI Ethernet Switch (EKI-7710G-2CI-AE)• ADAM IO (ADAM-6050-CE)

Parking Solutions

In parking lot control applications, connected devices can help with ticketing systems, control arms, teller houses, security cameras, digital signs and more. Ethernet extenders are ideal for creating a data connection to parking booth, as they work great in situations where there are already existing wires. When connecting multiple devices, use serial servers and Ethernet switches. Isolation offers additional protection for installed equipment. Fiber is a good choice for reliability when dealing with varying weather conditions.

What To Use for PoE Cameras:

• IMC Media Converter (IMC-390-SE-US)• EKI Ethernet Switch (EKI-7710G-2CI-AE) with SFP Option

NEMA TS2 Product BenefitsWhy Ethernet Routers?

• Supports VPN tunnels for secure private communications to remote sites

• Provides fi rewalls — address, port and protocol fi ltering limits network access in either direction

• NAT for public to private IP — there’s no need to pay for a public IP address for each device

• Supports HTTPS and SSH for secure encrypted communications

Why Ethernet Extenders?

• Eliminates the need to install new fi ber• Extends Ethernet over copper wire up to 1,200

meters

Why Ethernet Switches?

• Manages and connects multiple Ethernet devices• PoE options available for cameras and access points• Gigabit options for high bandwidth applications• Fiber options for extended distance connections

Why Ethernet Serial Servers?

• Ethernet enables traffi c controllers with an Ethernet to Serial communications converter

• Connects digital signs• Monitors roadside radar

Why Ethernet Media Converters?

• Converts and extends Ethernet over fi ber• 100 base fi ber or gigabit fi ber options• Multi-mode or Single-mode fi ber

Why Serial Products?

• Uses isolators to protect the serial interfaces• Converts RS-232 to RS-485

Why Wireless and Cellular Products?

• Supports remote connectivity• Eliminates the need for long cable runs
