Introducing the xPico – Smallest Device Server in the World

Posted on May 16, 2012 by Jonathan Witthoeft

xPico is a networking solution that enables Ethernet connectivity on any serial interface. This little, chip sized xPico is the smallest embedded device server in the world. It is a complete device server with a full IP stack and web server. It supports serial data rates up to 921Kbps and has the same functionality and user interface of the xPort.

xPico has added versatility to the xPort by removing its RJ45 circuitry. The end user can now use custom circuitry and is not bound to the xPort’s hardware components. The xPico therefore supports POE circuitry and boards that already supply an RJ45 jack and magnetics.

The xPico starts at $25.00 and is available both as a module and in a development kit

Application Adaptation – Creative Solutions for Customer Specific Applications

Posted on May 10, 2012 by Jonathan Witthoeft

“This product is NOT compatible with your application.” These are the dreaded words that no customer is glad to hear. Not only were you looking forward to using the device, but now after built anticipation and empty hopes, you are told it will not work. At Grid Connect we try to avoid this statement at all costs. Our technical sales advisory, expert technical support, and vast product versatility give us the tools to make our Bluetooth products work for you.

Recently a customer requested help using our firefly unit with a Siemens DDC. The only problem was that this DDC required a loop back of hardware flow control pins CTS and RTS. This is an option normally not supported.

End Device Flow Control Loop-Back

The flow control loop-back is a problem that is normally solved through a custom cable that would be in-between the firefly and the DDC controller.

This was not a possibility for the customer; the firefly needed to be directly plugged into the DDC. So we tested and came up with a different solution. We found that jumpering internal pins 6 and 7 of the firefly unit would directly loopback the RTS and CTS pins of the db9. This is a solution within the firefly and no additional cables would be needed.

Since the jumpers will not fit in a diagonal orientation, we suggest using wire wrapping rather than soldering so not to void our one year warranty.

The Future of Industrial Networking

Posted on December 13, 2011 by Jonathan Witthoeft

What is an industrial network driven on? What will prepare a network for the future? Microprocessors are the “Heart of the Network,” according to Jim Montague, executive editor at Putman Media. “Heart of the Network,” featuring our own Mike Justice, is the featured publication in the fourth quarter 2011 edition of Industrial Networking.

Mike Justice stated, “Microprocessors might be on the lowest layer of the network, but they have a huge influence.” Chips have evolved from simple standard microprocessors, to application-specific integrated circuits, field-programmable gate arrays, and so on. Design flexibility is what allows industrial networking to move into the future.

Gigabit Ethernet will help industrial networks keep up with the bandwidth requirements for increased network traffic. Many gigabit products have already hit the commercial network. It will not be long before the industrial Ethernet networks will need to speed up. With our new gridARM microprocessor, we are able to supply our customers with a cheap Gigabit Ethernet solution for adding fast Ethernet to their devices.

The gridARM microprocessor is designed for low cost products that require a fast Ethernet connection. This system on a chip is most flexible because it includes an ARM7TDMI core, 10/100/1000 Ethernet MAC, CAN controller, up to 3 serial ports, I2C, SPI, on chip SRAM, USB device, A/D converters, and interfaces for SDRAM, Flash, Compact Flash, external SRAM, and NAND flash.

10 Factors when deciding between Industrial and Consumer Networking Devices

Posted on October 20, 2011 by Jonathan Witthoeft

1. Protection against solid foreign objects

What solid foreign objects are a part of your operational atmosphere? Will your device need to be dust tight, protected against wires, or not protected at all? If maintenance is not an option due to distance or inaccessibility, then you might need to consider what objects can find their way into your devices enclosure.

2. Protection against water

This is very important in an outdoor application. You want your device to be able to withstand rain. Also what if you need your device to be submerged in water, or need to be able to hose down the device when cleaning an industrial area? These are all conditions that need to be considered when determining which device to go with.

3. Protection against oil, coolant, and corrosive agents

Hazardous materials can limit the range of products applicable for use. Without a doubt, you need to have an industrial product for protection against oil, coolant, and other corrosive agents that might be in that operational atmosphere.

4. Temperature range

There are typically two temperature ranges to consider in the specifications of a product: operational temperature and storage temperature. Industrial products tend to have wider ranges for both of these. If you need to store or use a device in an extreme temperature, you would want to use an industrial device.

5. Durability

Some applications require a tolerance for impact or fast motion. Some tests that are done on industrial devices include stationary vibration, shock, and vertical free-fall. Some devices are also given an impact rating from 0 to 20.0 Joules.

6. Surge protection

Surge protection ratings specify the protection level electrical devices have from voltage spikes. In certain conditions components need to be able to withstand large spikes in voltage. Industrial devices tend to have a higher range of tolerable AC and DC voltage spikes.

7. Electromagnetic response

In many applications multiple electronics are in the same confined area. Some of which might have motors, or other components that create EMF. It is important, in this case, that your device can tolerate different electromagnetic conditions. Industrial devices have higher electromagnetic resistance than consumer devices.

8. Power supply

Consumer products are usually powered with a wall plug. Industrial products are often powered in parallel to each other. They share power supplies, rather than having a dedicated power supply for each unit. Some have redundant power inputs that are used with redundant power supplies.

9. Enclosure mounting

Many consumer devices are designed to be set on a desk or other flat surface and do not include any mounting options. Industrial products include mounting options such as DIN Rail Mounting and Panel Mounting.

10. Longevity

Most industrial products in an industrial application would be functional approximately 3 to 5 times longer than a consumer device in normal IT application.

Announcing the gridARM System on a Chip

Posted on September 22, 2011 by Adam Justice

Today we are announcing the gridARM^tm, System on a Chip, with integrated Gigabit Ethernet. The gridARM is targeted at the low cost embedded marketplace where cost and performance are important. The cost for quantity 100 pieces is $10 each.

The gridARM is designed for low cost products that require a fast Ethernet connection. As most IT networks, PCs and laptops are all gigabit Ethernet, it only makes sense to have all your devices on the network to be as fast as possible. The gridARM is designed to be the main processor in the system. The cost of adding Ethernet to your product is now low and can be a marketing and performance advantage for your product.

The gridARM is available in volume today. The development kit includes an evaluation board, cables, JTAG emulator, power supply and a complete set of development tools including a royalty free real-time operating system, TCP/IP v4/6 library, web server, telnet and example tunneling software.

The gridARM is available in two packages – 225 pin BGA and 208 pin QFP. The gridARM chip includes an ARM7TDMI core, 10/100/1000 Ethernet MAC, CAN controller, up to 3 serial ports, I2C, SPI, on chip SRAM, USB device, A/D converters, and interfaces for SDRAM, Flash, Compact Flash, external SRAM, and NAND flash.

The gridARM is our third ASIC in the family. The LX and EX ASICs have been around since the early 2000 and are used by thousands of customers in commercial and industrial applications. The gridARM is manufactured for Grid Connect by Atmel Corporation.

Routers and Switches and Hubs…Oh My!

Posted on September 12, 2011 by Jonathan Witthoeft

8 Port Industrial Gigabit Switch

Hubs, switches, and routers are all the same in the sense of connecting network devices with each other at one of three speeds. Most devices are capable of both 10Mbs and 100Mbs and will automatically detect the speed. If the device is only capable with one speed then it will only be able to communicate with switches that also support that speed. Gigabit devices (1Gbs) are starting to slowly become more common as well. Gigabit switches, e.g. our GC-EKI-2728-BE, can be used with these devices to utilize that faster speed.

Speed aside, there are still key differences between routers, switches, and hubs that many people are confused about. I often see people misusing these titles and would like to clear this up. I will start with the least complicated.

A Hub is the cheapest option of the three. They are not intelligent and they simply forward all communication that is received on one port out to all of the remaining ports. All of the devices connected to a hub can see all of the data sent through it. The hub does nothing with the data being transmitted. Hubs are great in small networks without a lot of traffic.

5 Port Industrial Managed Switch

A Switch does a little more. A switch is intelligent. Switches recognize what devices are on what ports by analyzing that ports traffic. It is able to determine which particular addresses are associated with which particular ports. For example, if it sees traffic from my PC coming in on port 1, it will send all traffic for my PC to port 1 and not any of the other ports. With switches, most of the network traffic only goes where it needs to rather than to every port. On larger, busy networks this will increase the network speed. Managed switches, like our GC-ATC-405, have their own IP address and have configurable options such as directing traffic to certain ports or ignoring traffic of a certain protocol.

A Router is the most intelligent of the three. A router is a Layer 3 gateway, which means it operates at the network layer of the OSI model. It routes traffic from one network to another. It has the same functionality as a switch and a hub, but also does much more. A router is programmed to understand, possibly manipulate, and route the data it’s given. Most routers include the ability to hide devices behind a firewall as well as all of the functionality found in a managed switch. With the use of a routing table, routers have the ability to filter traffic, either incoming or outgoing, based on the IP addresses of senders and receivers. The entire configuration is done through some kind of user interface, e.g., a web page.

IP in your hand…Really!!

Posted on November 8, 2010 by Rick Rockershousen

The world’s tiniest device server, the NET232jr, was originally nicknamed by its first customer as “IP In Your Hand”. This clever turn of phrase gave us a few chuckles, but it does point out the amazingly small size of the NET232jr. The NET232 “junior” enables serial devices with IP technology in the smallest package available in the world (as far as we know!).

We were able to shrink down the size of our standard NET232 by getting rid of the power regulation circuitry and the power LED. This change requires that power be provided to the NET232jr over the serial port (coming from the serial device), and that power must be regulated at 3.3VDC or 5VDC. This obviously means that the NET232jr is not for everyone.

The NET232jr has been primarily used thus far by OEM’s who want to offer it as an add-on for their serial port devices, and who have the ability to modify the serial port of their product to put out the power required. You might ask “if you’re going to modify your product to put out power on the serial port, why not just go ahead and add the XPort (the main component inside the NET232jr) to your product instead?” Well, there are several reasons why you might not want to do that. First and foremost is cost. Maybe you expect only a limited percentage of your customers to actually need an Ethernet connection. Why put an XPort in every product? Why not just sell an add-on that is small, smart, cost-effective and can be customized to your specifications with ease? This is the motivation for the NET232jr.

Another interesting use of the “junior” is when you have a serial device that must be operational at all times, and you need to “live swap” it for servicing quickly and simply. If you use the NET232jr as the network connection, then you can leave the NET232jr attached to the network while you swap out whatever serial device is attached. This means you do not have to reconfigure the network connection for the new device; you simply plug it in and the NET232jr “remembers” the network settings. Thus, you do not need to call in IT personnel to replace your serial device – anyone can do it – just plug it in!

The NET232jr came into existence when a customer asked for something smaller than the NET232 (which is already one of the smallest Serial to Ethernet device servers on the market). Grid Connect is happy to discuss your project/product needs with you and see if we can find a solution – even if you don’t see on our website. We have on staff a team of engineers dedicated to finding solutions to your networking problems. Maybe you need a custom design that will fit in your enclosure or cabinet. Who knows – maybe you’ll even see an “IP in your cabinet” blog post someday!

Ever wanted to be a Fly-On-The-Wall?

Posted on September 13, 2010 by Rick Rockershousen

Small business owners, businesses with multiple retail locations/branches, and even individuals with an elderly parent living alone, can all benefit from our remote audio surveillance technology over IP!

Small business owners, who want to be able to listen in from home or other locations when trouble arises at their business, can do so using our IP Intercom/Paging Technology powered by Digital Acoustics.

Let’s say you have video surveillance of your retail franchise and want to hear when something happens. Or maybe you’d like to “yell” at troublemakers after hours that are on your car lot. Using the IP7-SE8, you can wire in a wide variety of speakers (including paging horns, ceiling speakers and wall speakers), and microphones, including very sensitive omni-directional mics, and be able to monitor and talk to your business location from any remote location with Internet access from your PC.

Using the Talkmaster Software on your PC (free with purchase of the IP7-SE8), you can communicate over the network with your business. Listen to disturbances, or simply talk to your employees and/or customers from anywhere in the world.

For multi-location businesses, you can make announcements to your employees at all locations at the same time. You can even play music and other recorded programs from your PC using the Network Music software. For locations where security is a concern, you can have a panic or help button installed by the cashier’s location, which would trigger the TalkMaster Software as an incoming call. You can then listen in and find out if any additional action needs to be taken.

For those with an elderly parent living alone, you can use a desk or surface mount intercom, which can be used to communicate in a time of need. This may be a life saving capability, allowing you to communicate with a relative who has taken a fall or is otherwise not able to answer the phone.

These flexible intercom and paging products provide extended security, surveillance, and paging applications anywhere there is an Internet connection. It’s an affordable, flexible and easy way to become a “fly-on-the-wall.”

*Note: Use of remote audio surveillance technology is subject to local, state, and federal surveillance laws.
