FULL VOTING LOGIC 3-SENSOR DIGITAL CCR CONTROL
In response to our continuing need for electronics to supply controls for the Mark 15, 15.5 and CCR-1000 Rebreathers, we have developed a fully functional Digital CCR control with LCD Readout, and now make this available to divers worldwide.
Yes - this will work with just about ANY Rebreather. It will drive a 6 volt Oxygen Solenoid (also available), and will accept Oxygen Sensor output from just about any Sensor (from an K-1D to a R-10, and everything in-between). If you are a Homebuilder, and want to move up to automatic CCR control, then this is for you.
Read below for a full description of how these new electronics work.

Here is a picture of the complete unit, equipped with a POD for use with the Mark 15 CCR. NOTE: The Control Module for this unit is EXACTLY 2 inches by 2 1/4 inches (SEE PICTURE) - don't let the size of the POD fool you - this board is extremely small, and can operate for about 50 hours on a single 9v Battery! The unit consists of the Control Board, a HUD Board, plus a 2 x 16 LCD encased in a clear Lexan Housing |
 |
For those of you who have a Mark 15 Series Rebreather, this is a view of the base of the pod with the underwater connectors. |
 |
We put our name on every product we make, so you know we care about what goes inside. It's that simple. |
 |
This is the LCD Module in the Clear Lexan Housing - you can see we have incorporated 2 Hermetic Switch sealed elements for the push buttons. One controls the Backlight, and the other controls the Menu. Both are used to call up menu items, and then to confirm your required changes - there is no "accidental" changes made by bumping a button against a reef or wreck. |
 |
This housing is the toughest we've come up with yet. We designed it out of clear Lexan for a reason: The Window of the housing is actually curved at a precise degree, forming a convex lens which MAGNIFIES the LCD Character Display - something our, ahem, "older" customers may particularly appreciate! To further ensure the integrity of this housing and the LCD encased within, we also fill the entire case with a dielectric fluid so that this wrist unit can dive deeper than most of us would ever dare. |
 |
Once again, you will see our name on this unit. We are very proud of the work that went into this design, and want to give our sincere thanks to Alex Varouxis of Associated Design who helped create it, as well as Will Smithers for being the genius behind all of our electronic products. Anything worth owning in the dive business is usually the product of more than one man's vision or expertise. Our philosophy is that by combining the talents of others with our own vision, we create a better, more reliable product.

Now on to the works of the thing: Upon power-up, you will notice that your Surface Interval timer is set to 00:00, there is no Set-Point yet selected (the empty field just next to the Surface Interval Timer), all three sensors are currently being read by the electronics (the three ***) - If any one sensor is "Voted Out" by the electronics, a "X" will appear in it's spot instead of an Asterisk. The next spot, where there is a "0" on the screen is your Dive Time - as you can see, we haven't gone diving yet. Moving down to the next line, we have your Maximum Depth, and the three Real-Time readings of your Oxygen Sensors. |
 |
As you can see here, in 100% O2, they list each sensor. Any deviation of any one Sensor can be detected this way immediately by the diver, without a need for a Secondary Display (even though the use of one IS a requirement of ANY CCR diving). |
 |
Here is a finger pushing the Button to select the Menu Option. When you press this button, the Menu (located in the spot used by the Set-Point - in between the 00:00 and ***) will scroll with each push of the button (or automatically when held) through the available selected Set-Points of .4, .7, 1.0, 1.2, 1.4, MAN (For Manual Control), then if you are on the surface - CAL. |
 |
When you select "CAL" (for "Calibrate) the unit will prompt you through the Calibration Procedure. |
 |
It prompts you to fill your loop with O2 (and then flush it at least 3 times) before proceeding to the Calibrate function. This ensures that YOU have control of the calibration process. You must manually inject Oxygen into your loop, then flush it out at least THREE times (you can do it only once, but three is recommended).
|
 |
When done, you press "GO" |
 |
The unit will then start calibrating itself. |
 |
It will then inform you that it is Calibrated and ready to dive. |
 |
Inside the Lexan Housing is mounted a Tri-Color LED which coupled with the HUD Electronics in the POD gives you a visual reference as to your exact ppO2 without even having to look at your Primary Display. In this way, coupled with a working Secondary, you have TRIPLE Redundancy in your Oxygen Display System. No other rebreather control on EARTH offers that kind of redundancy out of the box. |
 |
Here is the unit during a dive - you can see your Current Depth (98 FSW), your Maximum Depth (114 FSW), your three Sensor Readings (1.0, 1.0, 1.0) and your elapsed Dive Time (in this case, 0 - since we took the picture too soon after taking it down for a dive!). |
