Any dive reports to share? :wave2:
X-CCR Questions
- Thread starter Yamahadrummer
- Start date
I have been diving in Cave Country over the past two weeks on the X-CCR. A phenomenal unit. Not a single problem or concern to report. Conversely, the electronics are amazingly simple to navigate, the screen is very bright and easy to read, the set point control is rock solid and the rest of the unit, like it's predecessor the HammerHead CCR, is built like a tank. Obviously, I am a bit biased in this equation, but I can tell you that we would not be distributing it if it didn't meat our criteria. Off to Eagles Nest tomorrow, and Deipolder on Thursday and Indian on Friday. I love this unit!
By the way, last week there were 6 HammerHead CCRs, 2 X-CCRs and on Defender CCR all diving in Ginnie Springs at the same time. A great family of related CCRs giving rock solid performance.

'Sounds Great, Randy, please keep the reports coming! :thumbsup:
Pic and videos would be much appreciated!

Maine must be cold this time of year... Why don't you head south to cave county and share with us what your learn?

Lol!
SubGravity's X-CCR website will be up and running within the next couple of weeks. In the meantime, you can check out the SubGravity Facebook page and get lots of current information for both the X-CCR as well as the Defender CCR.
There are several instructors and instructor trainers in various locations throughout the world who have been diving the X-CCR over the past few months. It is a rock solid design built upon a long legacy of reliable and robust hardware combined with a phenomenal new set of electronics making this unit a real game changer (in my highly biased opinion!).
Hopefully this will answer a few questions for you. Additionally, Please feel free to download a quick overview flyer at the dropbox link below:
**X-CCR:**
Next generation CCR with completely new electronics - most notable the CO2 sensor and the digital HP sensors. CE approval in process.
O2-sensors and **built-in CO2 sensor** in the easily removable cartridge
Easy to dry, check or replace the sensors
Simple multi LED HUD
Ultra steady setpoint control
HP sensors for digital tank pressure (no SPGs!)**
Full color OLED screen
USB interface for easy firmware update
Logs scrubber changed, sensor age and date of last calibration
Fully tested to 150m depth before leaving factory
Radial scrubber
Shrimp BOV as standard
Easy to use click-lok connections
[DOWNLOAD PDF **X-CCR** FLYER HERE](https://www.dropbox.com/s/apva673egt2vn7h/X-CCR.pdf?dl=0)
Please feel free to ask any further questions you might have!
Kind regards,

It utilizes digital communication between the head and handset. The HUD, primary handset and secondary handset are all connected to the head with stainless steel, double barrel o-ring, potted connectors rated for 5000 connections. If one of the components were to go down, it is a simple matter to pull a spare out and plug it in. It truly is plug and play which makes for easy field emergency equipment replacement.

Actually it depends on what you consider canbus. For example if you unplug primary it will continue working. It sends and receives signals.

Hi Michael,
as canbus I consider a cotroller area network-multiple controllers, multiple parameters, Limp-Home-Mode etc. Or practically: If you unplug primary, you can use secondary or third as controller. CAN systems provide the highest data-security in such systems.
Not simple, but the best solution today.

In my opinion, canbus is a much misused word. Our system uses two way digital communication with the ability to plug in multiple handsets, HUD, etc. We are not so concerned about the ability to have multiple controllers with the X-CCR as the electronics/controller are in the head and function perfectly even in the handset controller were to be lost.
Let's not get carried away. CAN is a fine standard, but it has at least three wiring standards, one of which is described as "fault-tolerant". Even then, one nice thing about this fault tolerance is that all the devices are connected two 2 wires (and ground), so there's no single point of failure, and if one wire goes bad, let's say shorted to ground, it can still use the other. One bad thing is that, if both wires are shorted to ground, the whole network goes down. This is a situation that an evil single point of failure system with a central hub would have no problem dealing with; isolate, and keep the rest working. So CAN is not perfect. With that in mind, and considering the amount of information available about either DiveCAN (since that's what we're talking about here), or whatever the xccr is doing, to wit: none whatsoever, it's more than a bit premature to call anything "better", never mind "the best".
Totally agree. I'm all for digital communication, I really am, but at the end of the day, it's not about being digital or CAN or whatever the buzzword of the day is, it's about what it does, not how it does it.
Cheers,
Matthieu

Does this mean that the unit will continue monitor and manage set point with out a controller?

Randy,
Is this system unique to your unit or is it used on other manufacturers systems or in other industries?
Second question is about plugging in 3rd party devices. Is this possible and if so who make them?
The tech world is going open standards yet I see more and more proprietary standards going into rebreathers and I am not sure why.

Peter, the X-CCR controller is integrated in the actual head electronics. The primary handset is simply a display screen and buttons which communicate with the head. That said, if the handset cable is severed or becomse non-functional for some reason, the head (i.e. controller) will continue to maintain the last known set point all the way to the surface or until a depth where the set point is no longer possible.
The X-CCR utilizes proprietary electronics developed for iQsub, which include the head electronics, the primary handset and the HUD. The secondary handset (or device) is any number of 3rd party devices including the Shearwater Petrel, Heinrichs Weikamp OTSC, or other 3rd party devices which are capable of monitoring 3 O2 cells.
I have personally been using a Petrel as a secondary on my unit which has worked beautifully in conjunction with the X-CCR electronics.

Very nice!

Does that mean that the controller will try to maintain the setpoint until the O2 is exhausted, as in firing the solenoid almost continuously above 3 meters when using a 1.3 setpoint if a handset is nonfunctional?
