Bus Depot
Application
Toll collection is an important factor in keeping buses running efficiently and on schedule. By utilizing smart card readers, passengers can quickly scan preloaded transportation cards to pay fees, allowing bus operators to pay more attention to safety.
Installation of CCTV cameras will capture video footage of events both inside and outside the bus along with sensors that monitor the acceleration and deceleration. When a bus enters the depot, the stored video footage and sensor data can be wirelessly downloaded to the central server inside the bus depot for long term storage.
However, electronic equipment placed on moving vehicles have hardships due to its niche operating environment. Using industrial grade equipment with M12 connectors to provide links between devices can prevent accidental disconnection of equipment because of its locking safety feature.
Challenges

Light Rail
Application
To provide an effective means of transporting large populations safely and in a timely manner to their destinations, extensive data collection that is accurate, reliable and real-time is required. Therefore, the most critical component of a passenger rail's automated system is its industrial networking infrastructure or backbone. This infrastructure connects components such as crosswalks, message display signs, PA systems, automated ticketing kiosks, train status displays, and cameras. Edge-level network connections must be able to satisfy serial, Ethernet, fiber optic and wireless needs. All data from these edge devices need to be communicated in real-time between stations, traffic intersections, and other outside areas that may come into contact with the rail system. Due to heavy vibration, connectivity devices that utilize M12 connectors greatly mitigate the chances of lost connections. If there are failures within a segment of the infrastructure, the effects can quickly propagate causing delays.

Railroad Crossing
Applications
Railroads have always been an important way of life. It has allowed for a quick and easy way to transport people, animals, food, fuel, and other goods across cities, counties, and states. Along the railway path, there are railroad crossing systems at intersections. These railroad crossings were built with safety in mind and to act as a barrier against intrusion. It is crucial the railroad crossing systems are always networked correctly otherwise accidents can occur.
Every railroad crossing has a nearby control cabinet housing industrial-grade equipment to safely operate the warning systems. About 30 seconds before a train arrives at an intersection crossing, the train trips a track circuit, triggering the crossing signals. Lights begin to flash and bells at the top of railroad crossing masts begin to ring, and after a few seconds, the gate crossing equipment begins to lower. A serial to fiber converter inside the control cabinet allows for these safety measures to occur. The serial converter can transmit data long distances via fiber to the next railroad crossing. Eventually, all this data is brought back to a central control room for monitoring.
Application Requirements
- Automatic serial data transmission between railroad crossing intersections
- Solutions with ESD and EMI protection
- Optical fiber media path to extend distance and prevent corrosion
- Built in serial optical isolation and high surge protection
- Compact design to fit in existing enclosures
- Wide range operating temperature support for any ambient weather conditions
- High industrial grade with long product life cycle
Toll Plaza
Applications
Toll plazas contain different types of communication, control, and monitoring devices to effectively manage the infrastructure. Devices such as vehicle messaging signs, loop detectors, video monitoring, weather stations, and toll collection booths provide a great deal of data in a variety of communication mediums that require connectivity. Furthermore, there is a growing trend moving toll roads toward Electronic Toll Collection (ETC) and Open Road Tolling (ORT). The ability to perform ETC and ORT reduces traffic bottlenecks and allows travelers to pay tolls without stopping, thus increasing toll collection efficiency and keeping highway congestion to a minimum.
The constant flow of data sent to and from different locations within the toll plaza can benefit from a managed switch fiber backbone. Fiber optics provide hardware advantages for long-distance communication, swappable SFP fiber connectors, and noise immunity for data integrity. Additionally, industrial managed Ethernet switches provide features for advanced control and oversight of the network that assist in network redundancy with sub-second recovery times, Quality of Service (QoS), email event notifications and remote management.
Challenges
- Real-time data transmission

Additonal PoE features, such as remote PoE remote power management and automatic end device power recovery can also be managed.
- Antaira's industrial serial device server series provides multiple RS232 connections bridging legacy serial measurement devices to transmit data bi-directionally and allows users to set up a ring topology network for dual data redundancy.
Traffic Monitoring
Applications
A traffic controller is able to utilize input statistics and information from sensors and other devices to provide data about the number of vehicles and pedestrians waiting at a traffic intersection. An industrial Ethernet switch can expand the number of connection points for all Ethernet-based field equipment. Beyond standard connections, industrial Power over Ethernet (PoE) switches can provide power to cameras, wireless access points and other devices. The traffic controller can then use data to make adjustments by lengthening green lights or skipping turn signal phases when no vehicle is present in order to alleviate traffic.
All information needs to be brought back to a Traffic Management Center (TMC) for more management and control capabilities. Managed Ethernet switches with fiber-optic connections in each field traffic cabinet provide long-distance communication at high speeds and infrastructure redundancy to ensure data arrives at the TMC. As our transportation system further evolves into an intelligent transportation system, the need for higher speed communication and network redundancy is critical in maintaining a fast and reliable network.

Weigh Station
Applications
Weigh stations implement advanced equipment to quickly evaluate and weigh all trucks. Electronic bypass transponders provide a weigh station with not only truck but also driver information. As the truck approaches the weigh station it is automatically weighed by a system known as weight in motion. If the truck is within regulation it may continue on without stopping. However, due to several factors such as speed and multiple axle vehicles, the weigh-in-motion systems are not always reliable and the driver may need to pull over for more accurate measurements.
The weigh station infrastructure requires a substantial amount of equipment to accurately assess each vehicle that passes through. Weigh stations utilize a variety of devices that use many communication languages. Vehicle message signs and other devices use serial connections to transmit data. Due to the need for wide-area coverage, weigh stations benefit from the use of a fiber optic backbone. Fiber provides the capacity for long-distance communication, high bandwidth, and noise immunity. Industrial Ethernet switches can be utilized for additional equipment including PoE cameras to complete a comprehensive system for monitoring and data collection.
