S9 SpO2 module - can anyone ask their rep what one ?

So you need a cable adapter from 6-pin to 3-pin at the question mark in the image below?
How does this work without a reslink for the S9?
Does this properly summarize the challenge, or am I missing something?

Looking at the picture of the S9 oximeter adapter (http://www.s9morecomfort.com/s9morecomf ... er_big.jpg), the 3 pin hole looks similar to the ApneaLink pictures here:

http://www.resmed.com/us/assets/documen ... er_eng.pdf

Looking at page 3, pictures D and E-6, esp E-6, it clearly shows a wire with 3 pins at the end. Maybe the Nonin 3012 itself comes with an oximenter cable that has the 3-pin adapter.

Page 3 of the ApneaLink document here (http://www.resmed.com/us/assets/documen ... er_eng.pdf) has a picture of the Nonin 3012, so clearly that's the oximeter to get. Hard to find the names of the connectors.

I shall ask my DME when I visit them next time.

The frustration in a nutshell !!!

10 points for such simplicity. I have put so much effort into working this out & basically might have had it working 18 months ago had I been able to buy a Resmed style 3-pin plug AND found a document that stated the real model needed was the 3012 (vs the then common 3011).

I went to all the websites that listed plugs & sockets & visted 2 major importers but no one recognized the Resmed baby. That became my brick wall.

DSM

PS the data from the Nonin xPod/iPod is serial TTL and there are lots of low cost boards (just like the Nonin OEM kit) that can take TTL serial signals and convert that to serial DB9 type signals. But all that would do is rnable me to plug the Nonin into my PC & not have the data gathered by the Resmed machine - the OEM kit allows me to feed either a 301 or 3012 xPod into a PC. But I could always do that with any recording or serial output SpO2 unit.
I used an Ohmeda 3740 for a couple of years feeding its collected nights data into a program I wrote that then fed the data into an XL sheet & then produced a graph.

The real want is to just feed the SpO2 data into the Resmed & extract it along with all the other data & view it all together in ResScan.

Just realised that what you say re the 3212 iPod is not correct in that the 3212 iPod replaces a 8000AA probe + 3012 xPod.
Think of the 3212 iPod as an xPod with the finger probe built in. i.e. replaces both the 8000AA and the 3012 xPod.

The 3212 replaces both the top & middle diag, as a single unit.

D

#2 DreamDiver, marry the left half of diag 1 with the right half of diag 2 and call that marriage an iPod 3212. As said it then is an alternate to the diags 1 & 2 together which are the 8000AA probe & 3012 xpod.

I am pretty sure that the S9 also use the 3012 / 3212 Nonin and that same Resmed 3-pin plug. 18 months ago after receiving my Nonin OEM kit I sent pics of the REsmed plug to Nonin in the US & was told, we have no idea where that plug comes from. Either Resmed source it or they do a special production batch of REsmed compatible Nonin units. Slink's Resmed compatible unit seems to bear this out. Her one is a brand that appears to be a subsidiary of Nonin.

Without that plug I have to hard wire the cable into the reslink or attach another socket externally on the Reslink (don't really want to bucher it to that extent). After all the effort & research I had already done - I just put it aside & moved on to other projects.

I would be delighted if we could source both the plugs required as the cables are easy to then make up.

It looks like an audio connector I have seen. The 3 pin female microphone down this page looks like it is getting close to the ResLink adapter. Need to find a better picture:

It looks like that 61-603 part number is from Philmore:

MULTI-PIN MOBILE CONNECTORS
Although these connectors have been historically identified as microphone connectors. Today they are used in a wide variety of industrial applications which require reliable, economical multi-pin connections, particularly for rugged mobile use. The positive screw-on retaining ring, and built-in strain relief, provide reliable contact under extremes of shock and vibration.

Can we file/machine a plastic FEMALE 3 pin connector to fit? (edit - had male)

Gotta run for a bit! Great work DSM! And DD & manas! Fantastic stuff!


Edit: Looking around a bit for "3 pin in line male microphone connector" and "XLR3" connector. There is a Wikipedia entry:

http://en.wikipedia.org/wiki/XLR_connector


And a blog post on wiring mic cables.

I've updated the image per DSM's suggestions. Does this hit the mark?



This adapter looks entirely different from the S9 adapter.
Either way, one Reslink or the other is necessary, eh?

The connector for each machine is a proprietary design, unique to that reslink model. This is poor design. These connectors should be industry-standardized. Non-standard connectors that aren't similar from model to model are even more outrageous. The beveled design of the Reslink S9 looks like it would also be more likely to pull out by mistake than the S8 due to its beveled connector. Pffff...

DreamDiver,

That looks just right. But it is interesting that the S9 use yet another plug !!!.

I am pretty sure (but until I read it in a Resmed document ) that the Nonin data type #2 devices (3012 & 3212) will be the ones that work with the S9, the only doubt is that they did change it & either that was because they swapped type (possibly brands) or were maybe just being difficult. Actually, reversing the type of plug does make some sense in that the pins showing on the Reslink are 'live' - there is a 5v + & - on 2 of the pins & shorting them would affect the Reslink whereas making the SpO2 module socket on the S9 to be female protects those pins better.

So we now need 2 types of cable 1 for the REslink & 1 for the S9.

DSM

Unadog,

Microphone connectors were my 1st choice & that little plug I was holding in one of the pics was from the closest match I could find.

But, the shape of the Resmed Reslink socket is such that we would need a milling machine to reshape the connector & that is kind
of like cracking a peanut with a mallet.

The simplest of all solutions (but inelegant) is to clamp a 6 pin socket onto the outside of a Reslink. The socket being of the type that accepts the Nonin xpod & ipod 6-pin plug. Then run the cord in through a hole drilled in the Reslink where the wires get soldered onto the matching points in the existing socket.

One other problem I never solved (because there seemed no point) was locating a source of sockets for the 6-pin xpod/ipod plugs. If I could get some of them I could more easily test out a connection to the Reslink.

DSM

Some thoughts re the S9 'adapter' for Spo2 unit.

It may well be nothing more than one of these ... (se section 1.5 - original TTL to serial converter).

http://wiki.laptop.org/go/Serial_adapters

The Nonin OEM kit caomes with a similar sort of card that takes TTL levels and converts them to Serial signals.
I suspect the S9 accepts serial signals & that the SpO2 'adapter' does that conversion. Only way to prove this
is to open one up & take a look.

DSM

Dave21,

After reading your skew survey it dawned on me that the SpO2 data in the new S9 as held in the file on the SD card, may be in readable format.
The data held in the file could well be the raw data captured from the 3012 xPod. If that proved to be true then to get our SpO2 data into ResScan may merely be a matter of capturing data from a compatible device (e.g. the 30123212 units like I have) and reformating it into the format Resscan expects.

I have no problem producing a small shareware program that reads one format or text file & rewrites it into another. That is the easy part.

So I am wondering if anyone has an SpO2 data file off an S9. Perhaps there is a sample file with the latest Resscan version (will check mine tonight).

What about a Dremel?

I don't have one, but I know folks who get them spend their days looking around for things to attack.

Michael,

I have a dremel (just forgot about it ). Yep that might work if I can get a decent grip on that little plug bit.

So grinding that plug down might just be worth it as a test . Just need some of those 6-pin sockets for the xpod & ipod.

DSM

I told my DME that I needed the S9 Oximeter adapter and an oximeter. She asked the rep and told me that the adapter isn't yet available in the US and that there is no compatible oximeter available here. Guess the US is behind AUS in this.

So what are you going to do about that, other than complain?
