We’re proud to offer turnkey, one-stop shop MIL-STD-1553B solutions here at MilesTek, including the industry’s most complete line of data bus couplers for MIL-STD-1553B box-style and in-line couplers.

So here are just a few facts about the MIL-STD-1553B serial data bus worth knowing:

How was the MIL-STD-1553B standard developed?

Like much of our nation’s IT infrastructure, MIL-STD-1553 was actually designed by the military in the early 1970s as a way to replace analog point-to-point wire bundles between electronic instrumentation. In 1978, the version was upgraded to MIL-STD-1553B as a way to boost both compatibility between designs by different manufacturers and overall flexibility, through providing explicit specifics about the electrical interfaces.

For example, in the F-16 Falcon fighter jets which first featured the standard, MIL-STD-1553B helped reliably connect and integrate the weapons systems onboard with the mission computer and other applications.

Minus a handful of minor updates throughout the years since then, the data bus has remained the most popular and reliable militarized network for more than 30 years now, used most prominently in military machines like F-16 Falcon fighter jets, satellites, missiles, and the International Space Station. Commercial aircraft manufacturers have grown fond of the technology as well, thanks to a strong, mission-critical track record of excellent EMI performance, dependability, and robustness.

Cool. So how does it work?

The MIL-STD-1553B bus features four primary elements:

1. The bus controller, which manages the information flow.

2. Remote terminals that interface one or more simple subsystems to the data bus and respond to commands from the bus controller.

3. The bus monitor, which is used for data bus testing.

4. Data bus components (data bus couplers, bus cables, terminators and connectors).

Data is transmitted sequentially, bit-by-bit, and received then in a multiplexing scheme over two copper wires from computer to computer (usually at a rate of one megabit per second). In most vehicle uses for the MIL-STD-1553B, redundant buses are employed.

LAN topology usually encompasses bus couplers (coupling transformers with fault-isolation resistors), terminators and cabling via twinax cables (twisted shielded pair), and concentric twinax connectors (with a center contact and an intermediate cylindrical contact).

What’s the advantage of couplers?

Couplers play an important role in the overall system. Basically, they help reduce reflections and maintain signal impedence levels, resulting in the sort of mission-critical reliability that’s demanded from the system. Without couplers, there’d be no DC isolation or common mode rejection, and a simple shorting fault between the device’s internal isolation resistors and the main bus would lead to a failure of the entire bus.

Part of this function has to do with the bus coupler’s transformers, but there are also built-in fault isolation resistors designed to protect the main bus during a short circuit in the stub.

So what does MilesTek provide?

And at MilesTek, we offer the industry’s most complete line of MIL-STD 1553B data bus products, including:

1. Box-style couplers — From one-stub couplers to eight-stub couplers, and everything in between.

2. Inline couplers — From one-stub inline couplers to four-stub inline couplers—these are used in vehicles where light weight and small size are important.

3. Bus coupler kits — Integrated kits that include bus couplers, terminators, and cable assemblies.

Maximize viewing potential. Improve demonstrations and presentations. Make video distribution easier, cheaper, and more effective. These are the sorts of opportunities our new VGA over CAT5 multiport transmitter and receiver system open up for our customers—and they’re flying off our shelves as result.

Basically, the system makes it easy to extend and split a single VGA source signal (say, from a laptop) to as many as eight different remote displays (usually HDTVs, a projection system, or computer monitors, for example), up to 1,000 feet away. >From there, from the loop-out port of the receiver/distribution amplifier, you can expand that original signal to two additional levels of receivers.

In other words, the multiport extension and expansion system allows high-definition VGA video and audio to run through common CAT5E and CAT6 cables, which are less expensive and capable of maintaining high performance quality over much longer distances than the more costly and bulky VGA cable (in this case, up to 1,000 feet). Thanks to smaller cable size and end connectors, CAT5E and CAT6 cables are also easier to install.

So think of all the scenarios that could benefit from a flexible high-def video experience:

  • Classroom or boardroom video distribution
  • Easier control of presentations from multiple laptops
  • Tradeshow demonstrations
  • Multiple overhead projector systems controlled from a single video booth
  • Large lecture halls with multiple screens
  • Large church gatherings with active, dynamic video presentation.
  • Divided office environments

That one source can easily and effectively be multiplied and customized in the way that best fits your needs. Here are just few capabilities and features the VGA over CAT5 multiport transmitter and receiver systems include:

  • 4-port transmitters featuring local pass-thru ports, which provide VGA/audio signal to up to four remote receivers.
  • Receivers with built-in 2-Port D/A and daisy-chain ports.
  • Receivers with excellent equalization and gain control.
  • Expansion as needed off receivers with 3-level daisy-chain capability.
  • Support for VGA/UXGA up to 1600×1200 @ 60Hz up to 330 ft.
  • A starter kit that includes (1) 4-Port Transmitter, (1) 2-Port Receiver, and power adaptors for both.
  • Additional receivers for expanding (sold separately).

All of our AV over CAT5 solutions are popular for the flexibility and customization they provide. The VGA system is just one more example of how our products can make life easier. Contact our AV solutions experts for more information.

Our new HDMI Over Single CAT5E/CAT6 Splitters and Receivers allow one HDMI source to be split and distributed to as many as eight separate HDTV displays over a single run of CAT5E or CAT6 cable.

They work with a full range of compatible sources, like Blu-ray DVD players, gaming consoles like Playstation 3 and XBox 360, computers, satellite/cable set-top boxes, and personal video recorders like AVCHD camcorders. And because they allow for the use of CAT5E and CAT6 cables (which cost less, are easier to install, and perform better over long distances), the splitter and receivers sets can extend the HDMI signal up to 164 feet while maintaining an impressive level of quality at 1080P/60Hz.

They’re easy to install, improve distance, and give you the ability to adapt and customize the way you present video.

So imagine, for a second, in how many ways this might come in handy:

  • Conference room presentations
  • Corporate training environments
  • Retail displays
  • School classrooms
  • Lecture halls
  • Elaborate home theater systems
  • Divided office environments
  • Situations where crowds overwhelm available space

One HDMI source. One splitter. Either two, four, or eight HDTV displays receiving high-quality video over CAT5E or CAT6 cables (make sure you use high-quality cables like the ones we provide, as the most common source of picture problems is poor-quality CAT5E and CAT6 cables). The splitter and receiver sets let you control quality, improve security, and maximize and amplify the sharing and display of information.

If you did any holiday electronics shopping at all this Christmas (or didn’t skip over the Christmas shopping commercials on TV), you probably caught wind of all the fantastic new ways to watch TV: Higher and higher resolutions. Better and better picture. And the holy grail—in-home 3D television.

Welcome to 2011. Who knows that this year, and those to come, will hold in the world of high-definition and multi-dimension video. It can almost seem overwhelming—is it worth purchasing new technology when new technology these days becomes outdated so quickly?

We understand, so we’re offering you a way to “future-proof” your HDMI cable needs. Our new, cutting-edge high-speed HDMI cables are so far advanced beyond standard cables that you won’t need to worry about upgrading again until the distant future.

To understand this, you first need to understand the difference between standard HDMI cables and high-speed HDMI cables.

The fact that cables can be classified as “high-speed” is itself a new development, as HDMI Licensing, LLC—a collaboration between major electronics companies like Hitachi, Panasonic, Philips, Sony, RCA and Toshiba—only recently announced that cables would be tested as “standard” or “high-speed”. Basically, the difference comes down to performance speed, which plays a big role just what kind of picture the cable can help produce.

For standard HDMI cables (also known sometimes as “category 1” cables), tests usually show performance speeds of 75 Mhz and up to 2.25 Gps, the same as a 720p/1080i signal. For high-speed HDMI cables (also known sometimes as “category 2” cables), tests have proven performance speeds reaching 340Mhz and up to 10.2Gbps—nearly five times as fast. This wildly improved performance allows for 3D over HDMI when connected to those 3D devices you keep seeing advertised, boast deeper color and higher refresh rates, and support 4K x 2K and 1080p video resolutions—while staying backwards compatible for older HDMI versions. The high-speed cables boast the highest bandwidth currently available.

In other words, picture is better. Color is better. The overall visual experience is better, fuller, and more cinematic. That’s the difference. Here’s what the high-speed HDMI cables we offer currently provide:

  • HDMI Ethernet Channel, which allows for a 100 Mb/s Ethernet Connection between the two HDMI connected devices
  • Supports Audio Return Channel Functionality
  • Allows 3D over HDMI when connected to 3D devices
  • Supports 4K x 2K and 1080p Video Resolutions, like WQXGA cinema monitors.
  • Additional Color Spaces (sYCC601, RGB & YCC601)
  • Gold Plated HDMI (Type A to Type A) Connectors
  • Data Speed Transfer: 10.2 Gbps

The future sure seems like an incredible place. We’ll help you be ready for it— contact our HDMI cable experts for more information.

For years, our standard BNC connectors have defined the industry standard for coaxial cables. Our new mini BNC boasts all the same benefits as our standard BNC plugs, just with a smaller footprint. Designed for 735A and 734A coaxial cables, the DS3 Mini-BNC connector even uses exactly the same tool set as the standard BNC plug—making the switch to the mini-BNC as easy and painless as possible.

Let’s take a look at just a few of the benefits:

  • The smaller footprint maximizes space and functionality for those using it. In fact, the connector was designed specifically for DS3 central office applications, so that companies can install as many connectors and assemblies in any given area as their operations demand. In other words, its smaller size allows for a much higher density of assemblies, saving space and improving network capabilities.
  • Unlike many competitors, the BNC plug bodies are manufactured from brass, and then plated with premium bright nickel. Across the industry, many inferior brands are machined from cheaper die-cast bodies, which significantly lowers reliability and durability.
  • Additionally, the BNC connector body incorporates a beryllium copper wave washer, which allows it to flex during mating and provide uninterrupted continuity of the shield signal. Teflon, the best dielectric, provides the proper 75 ohm impedance, and securely holds the captive center pin. The MilesTek BNC center pins are plated with 30 micron inches of gold for maximum contact.
  • Pull strength is vital, especially on smaller cables like the 735A. At MilesTek, our BNC plugs have a diamond knurling for maximum cable retention. After testing thousands of cable assemblies, our BNCs recorded a pull-test performance of 49.3 inch lbs. on the 735A cable—unparalleled strength and reliability.
