V1 Upgrade
Delta P Technology Ltd is proud to announce an upgrade available from November 14th, 2005 which will enable VR computer owners to use both the standard VR decompression algorithm AND a new variation of the algorithm that we have developed which incorporates a variable permeability model.
We are calling it the V1 upgrade.
Once this is released new VR computers may be ordered with the V1 upgrade already installed or current VR owners may upgrade by returning their existing computer to us via you for the work to be done. This is not currently a PIN upgrade.
We enclose a spreadsheet with pricing guidelines to help you deal with enquiries and a new price list with the V1, V1a and V1b upgrades included.
The cost of the upgrade depends on the age of the unit being upgraded.
New VR computers and VR2s and VR3s manufactured since October 2004 which have Software Version V3.02aC or V3.03aC installed are already armed with the expanded memory needed to run the V1 upgrade. Therefore all that is required is the software upgrade itself. This will cost $290.00 retail.
If the computer to be upgraded is a VR3 with the later body style (circlips visible behind the switch pockets and a 7 pin I/O connector) and software version V2.1 CXR or V3.03aB installed, or a VR2 with V2.1CXR or V3.02aB software, the owner will need to purchase the expanded memory required as well as the software upgrade. This will cost $585.00 retail.
If the VR3 to be upgraded was manufactured before June 2003, which means it either has no I/O connector on the side or takes a 2 pin connector and has no visible switch circlips, then unfortunately the existing box cannot be fitted with the expanded memory required and will also need to be upgraded. The combination of box upgrade, expanded memory and V1 software will cost $960.00 retail.
When considering upgrading one of these older units, owners using analyser or rebreather cables should be aware that the new box will have a 7 pin connector, not a 2 pin connector.
What it does
The new algorithm is based on VPM BE and depending on gas selection and dive depth and time, it will in some cases provide a reduced decompression requirement, although this is not always true. What the new algorithm does is smooth out the decompression profile. There are no deep micro-bubble stops and 'normal' decompression stops begin much deeper. Generally speaking, the intermediate stops are longer compared with the standard VR algorithm and shallower stops are shorter.
A unique feature of the V1 upgrade is that, once it is enabled, divers can switch to the algorithm they prefer for the type of diving they are doing, even in between dives if they wish. On every dive the VR3 records tissue and bubble states using both algorithms so divers can swap between the two without compromising their ability to switch back.
