Industrial Ethernet Switch on 3U cPCI

MEN Micro has announced the G102, a fully managed 3U flexible multiport Gbit switch, with a 29 Gbit/s switch matrix, implemented as a CompactPCI Serial board. It occupies one system slot or one peripheral slot using a 4 HP front panel with three Gbit Ethernet ports on M12 X-coded connectors on the front panel. The new backplane concept for MEN routers and switches allows high flexibility in network applications and management.

02g102-03_rightThe G102 guarantees high speed, high efficiency and an extensive firmware supporting various protocols like security, time synchronicity, stability, as well as for temperature needs. The switch supports EEE (Energy Efficient Ethernet) as a standard on all ports, IEEE1588v2 on ports 1 to 12 and SyncE (synchronous Ethernet) as an option.

The G102 either features three Ethernet ports on the front and up to 22 ports on the rear, or alternatively all 25 ports on the rear. These include 12 ports with integrated 10/100/1000 Mbit/s copper PHYs.

The switch is fault tolerant and restores itself on its own: If a link is temporarily unavailable, frames can be sent via backup/redundant links (spanning tree protocol/link aggregation) and no data loss occurs. Its built-in test mechanisms make the G102 an even more reliable component in the communication system. The railway Ethernet switch is specifically designed for rugged mobile communication systems and fully compliant with the EN 50155 railway standard, qualified for a -40 to +85°C operation temperature and ready for coating.

COM-Based SBCs Offer High I/O Density

Diamond Systems has released its ultra-small COM-based ZETA single board computer family. Highlights include interchangeable COM Express COMs for scalability and long product life, ultra- compact size and an rich amount of I/O, including a complete high-quality analog and digital data acquisition subsystem.

Designed in the COM Express Mini Type 10 form factor (84 mm x 55 mm / 3.3 in. x 2.2in.), the Zeta family offers performance scalability due to its use of COM Express CPU modules. Three processor options are currently available: Intel “Bay Trail” E3825 dual-core 1.33 GHz CPU with soldered 2 GB RAM; Intel “Apollo Lake” E3940 quad core 1.60 GHz CPU with soldered 4 GB RAM; and Intel “Apollo Lake” N4200 quad core 1.1 GHz (burstable to 2.5 GHz) CPU with soldered 8 GB RAM.

zeta-enlargedThe use of interchangeable CPU modules in the increasingly popular COM Express Mini Type 10 format enables Zeta to serve applications across a wide spectrum of price and performance needs. It also offers customers the longest possible product lifetime by vastly simplifying migration to a new CPU when the current one reaches its end of life. Zeta is an excellent choice for applications with expected lifetimes of 10 or more years, including military, medical, and transportation.

Zeta’s two-board COM + baseboard construction yields the highest feature density possible in a given footprint. The COM provides the core CPU functions, while the baseboard provides the “final inch” for all the system I/O plus the data acquisition subsystem, power supplies, and expansion sockets. Zeta provides as much as a 60% reduction in size compared to boards in larger form factors offering the same level of I/O.

Zeta’s impressive I/O list includes the following:

  • VGA display and Single-Channel LVDS port
  • Dual Gigabit Ethernet
  • 4 USB 2.0 Ports + 1 USB 3.0 port
  • 4 RS-232/422/485 ports with software-programmable protocol and termination
  • 16 digital IlO lines
  • Optional complete analog and digital data acquisition system
  • Integrated wide-range 6 V to 36 V power input circuit

Zeta is available in two I/O configurations, digital I/O only or digital + analog I/O. The DIO only circuit offers 16 DIO lines with selectable 3.3V/5V logic levels. The full circuit includes 16 channels of 16-bit A/D, 4 channels of 16-bit D/A, 27 digital I/O lines with selectable 3.3V/5V logic levels, and 8 32-bit counter/timers, all supported by Diamond’s free, industry-leading Universal Driver data acquisition programming library. An interactive graphical control panel for Windows and Linux is also provided to control all data acquisition features.

Zeta offers multiple options for system expansion and mass storage. It includes a PCIe Minicard / mSATA socket and a micro-SD socket. A unique expansion connector enables the installation of a daughterboard that contains an M.2 SATA SSD socket, a second PCIe Minicard socket, HD audio and 16 additional GPIO lines.

A built-in heat spreader efficiently removes heat from the SBC to keep the processor and all internal electronics cooler for improved reliability. The bottom-side mounting configuration of the heat spreader provides a secure and convenient mounting system for the board. It also simplifies the installation of I/O expansion modules by eliminating interference or airflow problems that can occur with traditional heat sinks. All three models of Zeta are tested for operation over the full industrial temperature range of -40°C to +85°C, making Zeta well suited for vehicle applications.

Power Over Ethernet Solutions

Powering devices over Ethernet cabling seems easy, but there’s more to it
than meets the eye. In this article, Eddie Insam explains how it all works.

So you’ve designed a brand new Ethernet-based device. Perhaps it’s a clock, a weather sensor, or an industrial controller device. You plan to hang it proudly on your wall and connect it to a RJ-45 wall socket. But how are you going to power it? Where will the system get its juice? Surely, you aren’t going to disgrace your design with a brick wart. There must be a better way!

Why not feed power over the CAT-5 cable? Well, you’re not the first person to consider this technique.

The D-Link DWL-P50 is a ready-togo module. Ethernet in, Ethernet out, and a choice between 12- and 5-VDC outputs.

Photo 1: The D-Link DWL-P50 is a ready-togo module. Ethernet in, Ethernet out, and a choice between 12- and 5-VDC outputs.

Standard CAT-5 cable has four pairs, and only two are used for data in a typical 10- or 100-Mbps installation (see Figure 1a). So, it sounds obvious to stick a few DC volts down the spare pairs. Oh, yes. But hang on, life is never so simple. This is technology, remember? There has to be a catch somewhere. So, sit down and relax, I have the story.

Standard 10- and 100-Mbps Ethernet devices use just two of the four available pairs. The spare wires can be used to transmit power to the remote. Two possible methods are shown (b and c). But watch out! The power source must be smart enough to detect shorts and overloads and to avoid damaging components at the far end.

Figure 1: Standard 10- and 100-Mbps Ethernet devices use just two of the four available pairs. The spare wires can be used to transmit power to the remote. Two possible methods are shown (b and c). But watch out! The power source must be smart enough to detect shorts and overloads and to avoid damaging components at the far end.

It may not come as a surprise that the wise men at the IEEE thought about this for a while and came up with a standard (IEEE 802.3af). This standard has been around since 1999, but progress has been relatively slow. It started to take off only recently, mainly because of the availability of inexpensive specialist components. Tom Cantrell and Jeff Bachiochi have covered some of the available components and modules (Circuit Cellar 165 and 187). A wide range of parts are now available, including dedicated switching transistors, isolation transformers, and high-quality nonsaturating magnetics, making power over Ethernet (PoE) a practical proposition.

TECHNICALITIES
The IEEE document covers two main methods for sending power down the CAT-5 wire. One involves using the spare pairs. The other involves sharing with the existing data lines using center-tapped transformers (see Figures 1b and 1c). The latter method is beneficial when spare cable capacity isn’t available.

The method involving spare pins allows a decent amount of current to be drawn because the two spare pairs are paralleled together to increase capacity by reducing the total DC resistance. The present IEEE specifications allow up to 13 W of power to be transferred this way. This may not be enough for some heavy-duty devices, but it’s quite acceptable for medium-size and small items such as TV cameras and VoIP phones. An updated PoePlus standard is currently being considered. This will allow for up to 30-W capacity, while still remaining backwards compatible.

Transmitting power with center-tapped transformers is more limited. Pulse transformers and other magnetics in the Ethernet controller must be designed to take the full DC power load current without saturating. That isn’t an easy task for miniature surface-mounted components. The advantage of this alternative is that it leaves the extra pairs alone, an essential consideration in higher-speed gigabit Ethernet, which requires all four pairs to carry data.

POWER SUPPLY
Why can’t you just stick any old power supply across the spare wires? Because you don’t know what’s at the remote end, and you may run the risk of blowing up sensitive equipment. If you don’t believe me, take a look at Figure 2, which is a typical Ethernet terminator. This kind of circuitry is sometimes contained within a single metal enclosure called a MagJack.

This is a typical Ethernet termination. The resistors strapped to the spare data pins and center taps are there to balance the line and to reduce noise. They can quickly flash to smithereens in true Harry Potter style if any unmanaged DC power is placed on the cable.

Figure 2: This is a typical Ethernet termination. The resistors strapped to the spare data pins and center taps are there to balance the line and to reduce noise. They can quickly flash to smithereens in true Harry Potter style if any unmanaged DC power is placed on the cable.

Note the two 50-W resistors R3 and R4 across the center taps of transformers T3 and T4. They are branched in series to form an effective 150-W DC load across the input lines. Also note the two 50-W resistors R1 and R2 right across pins 7 and 8 and 4 and 5. These present a controlled impedance load to the otherwise non-terminated wires. They are there for robustness and noise reduction. This hookup is sometimes known as a Bob Smith termination.

If you connect a 48-VDC raw supply into such a socket, you will be driving a good third of an amp through these tiny resistors. This is guaranteed to vaporize them to kingdom come. Tiny SMD resistors are not built for such treatment.
