After 7 years of planning and 3-4 months of frantic building, moving the submersible from the factory to the ship was a big deal.

We are engineers; we could have each spent another 6 months working on our parts of the system, but Jim was on a schedule and perfection would just have to take a back seat to safe and functional.

So there we were. In the wee hours of the morning, in a light rain, watching the crane very carefully lift our sub Deepsea Challenger onto the back of a flatbed truck.

Visual Data Overload

One of my many jobs during those first few weeks at the factory was to review the graphics used on the pilot's touchscreen interface.

Put simply, I was asked by Jim to "fix them."

To be fair, the lead programmer had a LOT on his plate at the time. Each of the 180 or so devices had to be tested and re-tested for its performance and its interaction with the rest of the control network on the submarine... Time to make the display "pretty" was just not something any of the team members had.

(Also keep in mind Jim is a movie director as well as deep sea explorer. The "look" of a control panel is an important aspect in his mind's eye).

A new series of blog posts by Opto 22 Application Engineer Ben Orchard gives you a front-row seat.

Remember filmmaker and explorer James Cameron's dive to the deepest part of the ocean, the Mariana Trench, just three years ago? 

Ben spent 4 months with the Deepsea Challenger team, in Australia, Guam, and at the Trench.

Today's tech tip is for anyone spec'ing new I/O for your system. It's a "hidden gem" on our website: the SNAP I/O Configurator.

This fun tool helps you build an I/O unit—mounting rack, I/O processor, and SNAP I/O modules.

Pick a rack-mounted controller or brain for I/O processing. There it is, on the rack.

Need a Factory Mutual approved, channel-to-channel isolated, digital input for DC voltage? Piece of cake. Check the boxes and choose the one you want.

Add all the analog, digital, and serial modules you need. If the rack is too large or too small, just click to change it. 

If your building automation system uses BACnet—and many do—you can integrate it with your SNAP PAC System using our free BACnet Integration Kit for PAC Project.

We've just updated this integration kit to include:

Older wind farms still produce clean energy, but many weren't built for modern monitoring and control.

This lack of remote visibility causes problems for utility companies and other owners, who must immediately respond when regulators call for changes in production.

That's because the electrical grid has to be a Goldilocks kind of system: not too much electricity, not too little. It has to be just right.

Faster. Ever faster.

There are around 180 devices on the submarine that the Opto hardware needed to communicate with.

Since every signal could not have its own physical wire, all the devices used a serial protocol. Each device had an address and a set of registers that could take commands or report their status back to the control program.

The interior of the pilot sphere remained at atmospheric pressure (around 14 psi), so there was no decompression requirement for the pilot. The outside of the sphere however took the full brunt of the mass of all the water above it. At the Mariana Trench, that was around 16,000 psi.

Serial data, power, and video camera feeds went in and out of the sub via very (very) special connectors called penetrator ports, electrical and fiber optic cables that had been cast in glass.

Challenger Deep:

On the 25th of March, 2015, it will be the third anniversary of filmmaker and explorer James Cameron's record-breaking solo dive on the Mariana Trench, only the third man in history to visit the deepest point on Planet Earth.

Perhaps you have already seen the movie, "James Cameron's Deepsea Challenger 3D". (Go figure - I took time off work and saw the opening session at a local theater). If not, you can pick up a copy from Amazon or iTunes.

Quick tease, follow this blog for a chance to win the movie or a special t-shirt.

As in past years, around this time my mind frequently goes back to the role that I and the entire team at Opto 22 played in helping put Jim in the pilot's seat of this amazing submarine Deepsea Challenger.

Join me in this and the next few blogs, as I touch on some of the highlights that stick in my mind of this epic adventure.

G'day Mate!

Since I'm going to be joining the world of blogging here at Opto 22, I thought I would kick things off by introducing myself.

Born and raised in Australia, I moved to the USA to take up working for Opto, rather than with Opto, in 2008.

For some 18 years I used Opto 22 hardware and software to automate a large hospital complex. Pretty much every aspect of the hospital is either controlled or monitored by some part of Opto 22 gear.

HVAC, chillers, boilers, backup generators, ice banks, refrigeration, nursery, operating suites, the list goes on and on.

The cool thing? I could control all of it from my office.... in the basement.....
