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.
Given the complexity of the markets, products, and expanding levels of technology at Comtrol, we believe firmly in the words of Albert Einstein, “If you can’t explain it simply, you don’t understand it well enough.” This mentality, taken from one of the smartest men to live has led Comtrol to create a new type of data sheet: one that distills the complexity of a RocketLinx Power over Ethernet switch down to five key features.
UPDATE: Linux Support at Comtrol – Part II: Six Months Later
- Nick Thompson
It’s been six months since our first Linux post here at Comtrol, and I thought I’d give an update as to what’s been going on with Linux support here at Comtrol.
Kernel (not Distribution) Specific Support Continues:
Our support for the kernel, and not specific distributions, continues. We believe this allows us to offer the best and most wide-ranging Linux support possible. We have been able to support many customers with very niche distributions, and even a few who built their own distributions using LFS (Linux From Scratch) using this approach. We have been able to support incredibly non standard distributions for companies and other organizations that we would not have been able to with a distribution specific approach. We will continue to operate this way, supporting as wide of a range of Linux as possible.
We have announced our official partnership with Axis Communications through the Technology Partner Program (TPP), and look forward to working with Axis to continue to improve product compatibility, increase successful product integration and enhance end user experience!
“The Axis Technology Partner Program is designed to bring to market the ‘best of class’ solutions for channel partners and their customers,” says Vince Ricco, Business Development Manager, TPP, Axis Communications, Inc. “We are excited to formally welcome Comtrol to the program and look forward to collaborating with such an interesting partner to offer true problem solving technology solutions that go beyond common capabilities.”
Industrial Surveillance Partner Solution Note
“Our customers have come to expect the very best in reliable networking solutions for the past thirty years,” says Bradford Beale, President of Comtrol, “We are pleased to be involved in Axis’ Technology Partner Program. Our ruggedized line of RocketLinx™ Power over Ethernet switches has proven to complement the physical security solutions that Axis and its partners provide in North America, South America and Europe.”

The fracturing process, in order to be profitable, must be truly mobile. Thus, many pressure pumping companies located in both the United States and Canada have created mobile command centers inside vehicles to control the fracking operations directly from the field. These vehicles, often termed “data vans,” house important monitoring equipment. Sensors used directly at the fracking site such as pressure meters, flow meters and engine and pump monitoring sensors transmit data in various different protocols such as CAN bus, RS-232 and RS-485. Converting all of this data to a common medium – Ethernet – is necessary for the SCADA system to ensure the fracking process is safe and efficient.
Comtrol’s DeviceMaster RTS 16-port serial to Ethernet gateway is included in data vans as the center of communication with the field. As seen below, the data from the sensors is either converted from CAN bus to RS-232, or travels directly via RS-485 to the DeviceMaster. The DeviceMaster then relays that information via TCP/IP (Ethernet) to the SCADA system. The DeviceMaster provides great flexibility with software selectable RS-232/422/485 support, along with being reliable, rugged and tolerating use in a mobile environment for extended periods of time.

As the number of network connected devices continues to increase exponentially, an uninterruptible network continues to get more valuable. Without power, you have no network – without a network you may as well have no devices!
While there are many methods a system can employ to create redundancy, the base of redundancy often relies on three letters, U-P-S (Uninterruptible Power Supply). Regardless of the electrical chaos that may occur in every area around a system, the battery backup UPS maintains power to the parts of the system that need it most. If you plan to keep a series of PoE devices alive on a UPS, Comtrol’s RocketLinx switches have two key features that can help keep your UPS running like the Energizer Bunny®.
Before we get started: Where are the DC Power inputs on Comtrol’s Power over Ethernet switches? Most of Comtrol’s PoE switches support redundant DC power inputs (accepting various input voltages depending on model, but shown with +48VDC here) via screw terminal connectors as shown below. Taking some artistic liberties, you can see how two power supplies could be wired up!
We have recently improved our RocketLinx ES8108 series with:
- A smaller form-factor housing for higher reliability and increased MTBF (Mean Time Between Failures)
- Wider input voltage range resulting in flexibility for use in a wider variety of systems and applications
- High efficiency, low-power design significantly reduces power consumption over previous ES8108 and ES8108F series models
- Compliance with IEC 61000-6-2 and IEC 61000-6-4 heavy industrial immunity and emissions standards
