Locking Connector Types


A new page was added to hold a graphic for a Bayonet style locking connector. The page is linked off the page covering the definition of a BNC Connector. A small definition is also provided. Both pages are part of the Definition of Radar Terms section.

Also added a graphic holding page to cover the definition of Terminal Lugs. The Terminal Lugs diagrams reside in the Engineering Glossary of Terms section.
In addition to the pictures referenced above a few others were added to pre-existing pages. A few additional entries were also added to the Definition of Resistor Terms section, but no new pages added.

I also moved the Balun Definition to its own page as the definition was being duplicated on three other pages. The new page covering Baluns is linked from a number of pages including the Antenna Terms section, and Engineering Dictionary section. Of course each of the new pages have been added to the site-map, linked of the index page.

Circular Connector Manufacturers


Finally added some text to the Sealed Circular Connector page located on interfacebus.net. The page was created a few months back... So far the page is a collection of links to pages that list manufacturers that produce round connectors on interfacebus.com.

The listing groups all the different pages into one list, which should make round connectors easier to locate.

Looks like the web site could use a few more pages dealing with Military Spec connectors.

HTML Language Codes


A new page provides HTML escape codes for country languages. The page lists the more common html language codes, but depends on your location. The page is listed on interfacebus.com. However there is a main listing that provides a more complete listing of escape codes, --. The escape codes are used in the meta tags to determine which language a web page is written in or using.
The new page is listed in the site map, but the newest version of the -- was not up-loaded, not for one obscure page.

PXI Express


The new Personal Computer video interface bus, PCI Express has been out for a few years now. The PCIe interface replaced the AGP bus which was used as a high speed video expansion slot shipped in PCs. As a video bus PCIe used a number of redundant lanes, or 16x to archive its high speed throughput. Because of its 2.5Gbps transfer speed (1x) the interface also started to replace the aging PCI bus, used for all other expansion slot functions.

Any way the PCIe bus started to replace all the other embedded buses based on the PCI interface. The upgrade path for cPCI becomes cPCI Express, PCMCIA went to ExpressCard, MiniPCI becomes Mini PCI Express, and so on.

Because many of the upgrades use the same physical interface, board format and function, but only change the electrical interface, page additions have been slow. Of course it takes a year or so before the interface is adopted by OEMs too.

A number of years ago the VME interface bus migrated to an instrumentation bus called VXI, low noise ~ high rel. Compact PCI [cPCI] did the same thing with the PXI interface [Compact PCI for Instrumentation]. PXI continued the advancement moving to PXI Express, using PCIe as the electrical interface and dropping the PCI bus.

So, four new pages were added to the web site today relating to PXIe;
System Slot pin out, PXI Express.
System Timing Slot, PXI Express.
Peripheral Slot pin out, PXI Express.
Hybrid Peripheral Slot pin out, PXI Express.

The pages link off the main PXIe page and have a listing in the html -- but because of those additions the pages do not yet contain the pinout data. Like all new pages, I add the page before the data gets loaded. A number of pages relating to the embedded PCIe interface have been updated.

PXI Express uses the same card form factor as PXI and cPCI, and some VME board sizes.

COTS Definition


Added a new page to cover the term COTS, or Commercial Off The Shelf Definition. The COTS term was already being defined on another Glossary page, but I reduced that listing and added a link to the new page.

The COTS acronym was also used on two Acronym pages; 'O' Engineering Acronyms, and 'C' Engineering Acronyms. Both of those pages now have links to the new COTS definition page.
