Comtrol NOW



MINNEAPOLIS, Minnesota — January 14, 2014 — Comtrol Corporation today announced that its RocketLinx ES8509-XT industrial Gigabit Ethernet switch passed IPv6 conformance testing and now carries the IPv6 Ready Logo indicating full compliance with IPv6 networking standards. As of January 2014, Comtrol’s complete line of managed RocketLinx switches includes support for IPv6, the replacement for the current IPv4 Internet protocol. IPv6 improves both security and performance while responding to the immediate shortage of IPv4 addresses. The ES8509-XT is the first in Comtrol’s RocketLinx series to be tested and awarded the IPv6 Ready Logo for compliance with the IPv6 core protocols.

Selecting an Ethernet Switch to Fit Your Environment

Posted by

Comtrol RocketLinx Ethernet Switch

As a communications equipment manufacturer, Comtrol often suggests applicable products for a customer’s environment based on features the products have.  However, this is a two way street. The proper selection of an Ethernet switch begins with classification of the area in which your product will be placed; only next does it become important to select a switch that fits your environment.

Step 1 – Classify the area in which your network equipment will be located.

Depending on how critical your application is, this can be done with various levels of intensity.  Some users may choose a standardized measure, such as the MICE classification system (Mechanical, Ingress, Climactic Chemicals, Electromagnetic) to ensure an accurate and objective description in every area.  Others may rely on individual objective measurements such as temperature (°F/°C), moisture (% humidity), and known acceleration rates.  Finally, others may elect for a simpler, subjective system such as “Hot/Cold” or “smooth/heavy vibration.”

Ethernet Specifications

Step 2 – Select an Ethernet switch that meets the requirements of the area it will be located.

Now that the environment has been classified, the next step is to find an Ethernet switch, or set of Ethernet switches that meets or exceeds each of the characteristics defined by the environment.  By listing environmental specifications on every Comtrol RocketLinx Ethernet switch, this step can be as easy as completing a check list.

Selecting a PoE Switch: A powerful decision

PoE Switch

You just picked up some new Power over Ethernet devices – a few of the hottest new IP cameras. However, after opening the box you run into a series of unexpected problems.

PoE panel fitting First: Each camera comes equipped with its PoE injector capable of supplying the appropriate level of power.  However, prior to even mocking up your panel it becomes clear – four PoE injectors and a standard Ethernet switch will not fit!

In an effort to maintain a reasonable panel size, you ditch the PoE injectors in favor of a Power over Ethernet switch, a single product that will replace all four injectors and provide Ethernet switching.  So far so good.

Second: After deciding that a PoE switch will best suit your need, you set out on a search for the cheapest PoE switch you can find.  Before long you realize the injectors were provided so that the cameras receive the exact amount of power they are optimized to run at.  With this new concern in mind, the search moves from the “cheapest switch” to the “right switch.” In order to identify the right switch, you will need some information… but where do you look?

Monitoring power consumption of a device that is connected to a managed RocketLinx® Power over Ethernet switch

Power over Ethernet device power consumptionWinter is setting in, the days have gotten shorter, and the nights longer.  After a long cold day you find yourself lying in bed staring at the ceiling.   You start thinking about the day’s events and as you drift off somewhere between consciousness and sleep, you start to think about a project that you did this past summer where you deployed several outdoor 802.3at PoE+ cameras for a good customer of yours.  The thought of a summer project brings warm thoughts of fishing, camping and swimming… and your mind goes back to the project.  You wonder, how are those cameras holding up as each passing day gets colder and colder?

You bold upright in bed in a cold sweat.  Did I ever check to see if the cameras’ heaters came on??


Expect More from an Unmanaged Ethernet Switch

Comtrol provides alarm conditions with dry contact relays! 

– Joe House

Comtrol’s RocketLinx® line of unmanaged, industrial Ethernet switches are bringing new features to unmanaged switch users.  A typical unmanaged Ethernet switch is expected to do one thing – provide Ethernet connections – which is a job most any switch can do.  As the number of Ethernet devices is growing daily and expectations of the networked device continuing to rise, we believe the unmanaged switch should do more.

Dry Contact Alarm Relay

Whether in an industrial control panel connecting Ethernet based sensors or PLCs, or in a surveillance application connecting IP cameras, the truth has become simple… expect no failure, and demand a quick fix.  Each time an Ethernet device is offline, the resource is wasted.  A camera is only as useful as the ability to connect its image to the user – an electrical connection that requires, at the bare minimum, power and physical connections to the transmit.  If power in the switch is lost, the image won’t make it past the camera.  If an Ethernet connection is lost from either end or even cut in the middle, the image will quickly disappear.

Dry Contact - Port Alarm Relay - Ethernet Switch

How can you quickly, easily and economically protect against the above problems? An interesting application of the age-old concept: Dry contacts.  Every unmanaged Comtrol RocketLinx switch has the user-configurable capability to set a dry contact alarm via DIP switch selection.

Is it really that simple? Yes, by toggling a port’s associated DIP switch to the “ON” position, you have created an alarm condition specific to that port.  Pull an Ethernet cord from either device – circuit closes. Cut the Ethernet cord in the center – circuit closes.  Main power supply failure – circuit closes.

What can you do once the circuit is complete? The RocketLinx dry contact alarm circuit is rated up to +24VDC at 1Amp, so you can power any physical device such as a bell or light stack to indicate the exact port of failure, or even wire in the output into an alarm panel where your options really open up.  Dry contacts are simple; so is this system.

How much does this feature cost? These contacts are included on every unmanaged RocketLinx Ethernet switch. Ask your Comtrol sales rep to try one today!
