Interest in the PCI Bus is Falling

I was just updating some of the data relating to the PCI Bus yesterday, really just adding some data. There was no new page added.

The main page relating to the Peripheral Component Interface is the PCI Bus Description. Just a few lines of text were added, the real update occurred on the page containing the PCI pin out,[which does not have a page rank?]. I started to add a better description of the signals, and added a few more notes. There are also two additional pages that were updated, each related to PCI card size; Half Sized PCI Board, and Full Sized PCI Board. I guess the only other page is Manufacturers of PCI Boards, but it wasn't updated.

I noted a steep decline in page visits for any of the pages relating to the PCI Interface, by about 4-to-1 over the last three years. Google had data that goes back to 2004, so I posted their graph for PCI Bus searches instead.
The Graph is a Google Trend for the search term PCI Bus.

Industrial Rackmount Computers

As part of the section on how to define an equipment chassis specification, two new pages were added.

The first page covers Industrial Rackmount Computers. The Industrial computers page provides a few design hints and a listing of companies that produce industrial PCs. The original list of industrial PCs had resided on the Manufacturers of PC Chassis page. The PC chassis vendor page now only holds commercial products.

The second new addition covers Cable Carriers or Cable Retractors. A Cable Carrier helps manage cables between the equipment chassis and the chassis rack. Using a cable retractor insures that the cable assembles bends and moves the correct way as a chassis is being moved in and out of a rack. Cable retractors also insure that the cable does not bind on any thing behind the chassis or within the rack. Within a few days the page will also cover Cable Retractor manufacturers.

Also added two more chassis specifications to the chassis standards page. Of course the main page in the section now lists the new page additions. Two new link additions to the section include; Fuse Derating, and Power Supply Standards. Also fixed the link to manufacturers of Anti-Vibration products, which happened to be pointing to the Rack Leveling products page by mistake.

The purpose of the entire section is to show a novice how to design an equipment chassis, or how to write a specification so an OEM could design the chassis. In any case the pages provide many design hints and engineering guidelines as well as some do's and don't s concerning electrical equipment design.

The industrial equipment design section spans 46 pages with links to other relevant topics on the web site. Don't get burned when purchasing an equipment chassis, review the different section that are relevant to the chassis your designing.

The page covering manufacturers of chassis has a link to the top page in this section.
