Do unexpected Ethernet network shutdowns create a crisis mode with people on your case to find the problem? Utilizing redundancy schemes such as Spanning Tree Protocol (STP) can provide for fault-tolerant communications and keep people off your back! Learn the essentials and advantages of STP.

Wow...the Success of AHR Expo 2006
Wow, an industrial trade show and potential purchasers could be seen in large numbers in the aisles. That seems almost like a miracle in today's age of failing or poorly attended trade shows. AHR Expo was a resounding success. I read that AHR Expo was the best attended of all times. From my point of view, it was a great show for us because we had some face time with existing and potential customers. The flow of traffic was constant which made the time fly, and when your standing on your feet all day it is nice to have time fly.

Our focus was exhibiting the Plug-and-Play (PnP) Ethernet switches in our product family. There is an expanding need for Ethernet switches in many of the new building automation systems. We have designed many low-cost devices to fill those applications. Our popular EIBA5-100T is complemented by its DIN-rail cousin, the EIBA5-100T/R. These are low-profile, five-port, 10/100 Mbps, auto- everything switches.

[an error occurred while processing this directive] For those applications requiring minimum panel space the EISK5-100T is the solution, and if more ports are required, the EISK8-100T with eight ports fills the bill. Keeping costs down is a fundamental need for the BAS integrator and with our five-port switches priced at $99, there were a lot of smiling faces.

Our customers have already benefited by moving away from the office-grade stuff and spoke positively of the simple things we do to make Ethernet switches easy to use in control systems.

For example, the ability to directly connect to 24 VAC (or DC) without dealing with the wall-wart power converter is a huge plus. The fact that our units are easy to mount means no more Velcro®, duct tape, Super Glue® or double stick tape need to be used. You would be amazed at how many potential customers admitted to doing those strange things. And our switches have more to offer! Add the easy to view diagnostic indicators, the marking label to document your wired connections (here you would be amazed at how many folks chuckled when I talked about documenting the wiring—seems like it is not done as often as it should be), the UL 508 to keep electrical inspectors at bay, and auto-everything on the ports (yes, even the cable—use straight through or crossover), the switch will figure it out.
