You are looking for the perfect networking solution to match all of your traffic needs. You have a limited amount of funds for the project and can’t afford to replace all of your multi-mode fiber with single-mode fiber. So instead, you have to utilize both your multi-mode and single-mode fiber that is currently in the ground throughout the city.
How do you decide which switch to go with? With Comtrol’s RocketLinx® industrial Ethernet switch line you don’t have to worry about purchasing two different Ethernet switches to get the job done. Instead we have a full managed switch line that will take care of running multi-mode and single-mode fiber on the same switch.
A gigabit fiber backbone was required due to the bandwidth needed for streaming live video. Video streaming, signal controllers, conflict monitors, preemption detectors, and all other Ethernet connected devices needed to have 100% uptime. The city also needed an Ethernet switch that was flexible and had the ability to support single-mode and multi-mode fiber due to the different communication mediums between the intersections. Finally, due to the extreme temperature environments within a traffic cabinet, the managed Ethernet switch they chose had to be NEMA TS2 compliant, supporting a -40° to 74° C temperature range. With all of these requirements in place, the city searched for a managed Layer 2 field Ethernet switch that would meet the certification requirements requested and would provide multiple fiber uplink ports.
During this expansion project, the Nevada DOT chose Comtrol’s RocketLinx® ES8510-XT switch to enable data transmission from their traffic cameras to server room monitoring stations, eventually showing up on live feeds at the DOT monitoring station.
One of the monitoring systems involved installing two traffic cameras to monitor the traffic flow going both east and west through the Carlin Tunnel, just West of Elko, NV. Both cameras are connected to one RocketLinx ES8510-XT industrial Ethernet switch, which directs information wirelessly through a point-to-point wireless link to another RocketLinx ES8510-XT switch installed on a nearby mountain. The data is then routed down to Elko’s server room. Additional information from switch-camera installations of similar configurations near Elko is also routed to the server room, which sends all of the information to the DOT control center in Reno.
The Nevada DOT decided to implement Comtrol’s switches into their system as a cost-effective, easily-configurable solution for their needs. The RocketLinx ES8510-XT was chosen over the competition for the addition of an extra fiber port as well as for its maneuverability within the DOT’s system structures. The switch is also NEMA TS2 compliant, allowing for reliable operation in extreme temperatures ranging from -40° to +74°C.
The RocketLinx ES8510-XT is housed in a rugged aluminum enclosure that features an excellent heat dispersing mechanical design. The embedded software supports full Layer 2 management features, multi-form ring redundancy, network control, monitoring, security and notification. The RocketLinx ES8510-XT also provides a built-in watchdog timer and digital input and relay output to avoid undetected problems, providing the perfect foundation for building an industrial Ethernet infrastructure.
Comtrol has released a new power supply that was designed with a wide operating temperature range for extreme and outdoor applications. With its compact DIN rail design, 100-240V input range and adjustable output range, this power supply works perfectly with Comtrol’s device servers such as the DeviceMaster® RTS and industrial Ethernet switches such as the RocketLinx® ES8510-XT. Together, these products power and control applications such as access control, industrial automation, and security and traffic monitoring. It is also compliant with the NEMA TS2 traffic standard for transportation applications.
With no load power consumption less than 0.75W, supporting inrush current limitation and heightened immunity against electrical disturbances, this power supply provides up to 90.4% efficiency and operates in an extended temperature range to reliably function in even the most demanding environments.
