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

[dsm]

Here is a summary based on what I think the situation is now ...


1) - (a) Probe + (b) xPod (Nonin 3012) + (c) Reslink / S8 Reslink
(b) to (c) uses a special plug that plugs only into a Reslink

2) - (a) Probe + (b) xPod (Nonin 3012) + (c) ApneaLink
(b) to (c) uses a special plug that plugs only into an ApneaLink or an S9 Adapter

3) - (a) Probe + (b) xPod (Nonin 3012) + (c) S9 Oximetery Adapter
(b) to (c) uses a special plug that plugs only into an ApneaLink or an S9 Adapter

To use an original xPod with its ResLink plug, requires a special cable offered by
Resmed that converts the original Reslink type plug to the ApneaLink socket or
S9 Oximetery Adapter socket.

That I believe sums it all up except as to if the Nonin xPod 3012 supplied for 2 & 3
is exactly the same as the Nonin 3012 used in 1 BUT fitted with the different connector
now needed for the ApneaLink / S9 Oximetery adapter. It just does seem probable
that users with an ApneaLink & S9 have to buy an adapter cable to make use of the
original Resmed Nonin 3012, unless Resmed have changed the plug on the Nonin
3012 units they now sell. As someone has already pointed out, for Resmed, the
xPod used for Reslink must surely have a different Resmed part number to the
xPod used for ApneaLink & S9 Oximetery adapter.

So think of the ApneaLink and the S9 Oximetrey adapter as the same thing and
requiring the same Nonin xPod with its unique plug. The YouTube video below
shows the plug and socket.

The only way I will be confident is when I get to see one or clear pics of one. It
is always irritating that the Resmed pics of the units never seem to show the
connectors.

Evidence ...
This Resmed ApneaLink brochure shows a Nonin 3012 xPod connected to the same type of
socket as is on the S9 Oximetery Adapter. This strongly suggests that there is a version
of the Nonin 3012 xPod that has the new ApneaLink / S9 style connector.
http://www.resmed.com/us/assets/documen ... er_eng.pdf

The part number for the Nonin 3012 xPod is listed as USA=22304 Canada=22308

This pdf for the ApneaLink plus shows an xPod with a plug that connects directly to the Apnea link
and as already can be shown, ApneaLink has the same socket for the xPod as does the s9 Oximetery adapter.

Here is a YouTube video showing an ApneaLink & xpod

While looking for a Reslink youtube (none avail) I found this video shoing how
the S8 II dual stage dual impeller motor/blower works.

DSM,

Sorry for having thrown confusion into the mix. Again.
Still fog-brained. I'd forgotten we'd already gone over this.

I've revised all previous graphic summaries to show exactly what DSM is suggesting,
adapting some of his images into the mix. I hope this finally does help.

I've left out any apnealink imagery because we're less interested in buying the
apnealink, and more interested in the 'apnealink oximetry accessory kit' which is just a proprietarily rebranded and 'reconnectored' xpod 3012.

[DreamDiver]

This is an interesting pdf -- particularly page 7
http://nonin.com/documents/OEM_Family_Brochure.pdf
http://nonin.com/ProductDetail.aspx?ProductID=27

Contrary to other sources, my ResMed source suggests that they actually made their
ApneaLink and S9 Oximetry adapter to fit the Nonin Xpod 3-lead connector,
not the other way around. So if we buy direct from another source, the 3-lead
Xpod or Ipod - either one - should work.

Update/Edit: I called Nonin. They sell their XPods as an OEM item with three leads unterminated. The woman in charge of Xpods said that ResMed decides how to terminate them - hence, as we suspected, it is a proprietary lead.

DSM - Did you buy your XPods direct from Nonin?

You have traveled the same path I did - I bought the official OEM xPod test kit from Nonin but mistakenly chose the xPod 3011 as had become convinced that the data rate was the 3-byte per sec rather than the xPod 3012 / iPod 3212 which is 255 byte per sec. I rigged up the xPod 3011 to connect to my ResLinks but not a sign of data. Then at the time this thread began, I woke up to the fact that Resmed were using the high-data rate xPod units & not the xPod 3011. I at last saw the Nonin model number mentioned in an official Resmed document.

The Nonin test unit plugs into a serial port on a PC, it has a software program that monitors the port & when an xPod or iPod is connected it analyses the data and displays it in real time. It also can save the data to a file. The test unit AFAIKT works with all models of xPod / iPod. The test unit I got had a different connector to the type of connector on the xPods & iPods I bought from the medical supplier. I suspect the choice of plug fitted has to do with who Nonin sold the xPod/iPod units to.

I had also bought the xPod 3012 & iPod 3212 units from a wholesale medical supplier who was disposing of unwanted stock. I paid less for all of them than the price of 1 Resmed xPod & probe at the time ($US 600+).

I also spoke with Nonin & sent them images of the Reslink connectors & they told me the same story you got.

What I can do when I have some time, is rig up one of the xPod 3012 or 3212 units to the test connector & gather the data files then see if the raw data can be fed into ResScan by simply renaming the file to the name recognised by ResScan. I have to hack off that 6-pin connector to get it connected to the Nonin test kit & I have held off doing that as I would have preferred to find a supply of 6-pin connectors & do the job properly.

I would like to get some plug ends that would connect to the Nonin units I have as I can then make up cables & perhaps do some creative building using rubber or other molding material, that will allow me to make a ResLink plug.

I suspect that the Resmed ResLink & ApneaLink style plugs (same as used on the S9 Oximetery adapter) are non-standard.

Total Abbott and Costello, huh? Who's on first. That's it...
According to my source at ResMed, they are using xPod 3012 to report in format 1: 3bytes/1Hz -- Not format 2: 5bytes/75Hz. So your original rate assessment was correct - just not the model number.

Your suspicions are confirmed - ResMed terminates their own leads according to Nonin - they are ResMed proprietary.

Do you know for certain if the 3012's / 3212's you have will report in format 1?

Hmmmm, this is where it gets a tad murky.

The Nonin model number defines the rate !.
3011 = data rate #1 (3 bytes/sec) &
3012 = data rate #2 (255 bytes/sec)

See Nonin web site ref specs for iPod & xPod. When I fed 3 bytes/sec into ResLink (using a 3011) it failed.
It is clear I now need to hack one of the 3012 or 3212 units to prove the point.

Cheers

PS Here it is in B&W - see page 5 where the models & speeds are spelled out !

So we've got ResMed saying they're using 1Hz data on a 3012, but Nonin saying the 3012 is only available in 75Hz format.

I see your point. Well I'm flummoxed.

This exercise has helped me enormously as in gathering all the info together am satisfied there is enough good data (plus results of experiments) to explain the devices used, model numbers & data flows. The one aspect we don't have resolved is what brand of plugs are used. I took another look at medical equipment suppliers catalogs for plugs but it tends to be a useless exercise as a picture is hard to relate an actual socket/connector due to not being accurately able to measure sizes.

I am ready to experiment again & if indeed the 3012 feeds successfully into my ResLink then the only remaining issue is those elusive plugs & who makes them. And that we need 2 types 1 type for the ResLink & 1 type for the S9 Oximetery adapter / ApneaLink. Assuming as listed in their parts manual, Resmed do have an adapter that takes the ResLink style xPod & allows it t be plugged into an ApneaLink (& thus an S9 Oximetery adapter), the bet is Resmed would want around $US 80-100 for that adapter cable, then for S9 users a $269 S9 Oximetery adapter, then the cost of the xPod & probe.

Seems to me the only people who might purchase these at those prices, in even small numbers, will be clinics.

No wonder I was confused. If you look closely at that table on page 5 of the Nonin spec, they list 2 "order numbers" for the 3012, one with (3873-202) and one without a connector (3873-002). Resmed must purchase the no connector version (3873-002) and then terminate the cable with their connector. Funny that the spec doesn't mention the type of standard connector the 3873-202 uses.

Order #, Model #, Serial Format #, With Connector
3873-001, 3011, #1, No
3873-002, 3012, #2, No
3873-101, 3011, #1, Yes
3873-202, 3012, #2, Yes

I know what that is - it is the metal connector that came on my 3011 with the Nonin test kit. I'll try to do a pic this w/e

Does anyone have an update on this 'project'?

And BTW - are you aware that DeVilbiss IntelliPAP Auto *also* uses the Nonin XPOD for its oximetry recording?

According to the XPOD rep I talked to, they make the devices and sell them all with connectorless leads. Each buyer creates their own proprietary connector. If anyone at ResMed actually does know about getting just the connector, they aren't telling me. Creating our own would probably void the warranty. Even if DevilBiss actually uses the same version (there are several) XPOD device, they may still not use the same connector. I'd be interested in knowing what the connector looks like for the IntelliPAP.

I'd be interested in knowing what the connector looks like for the IntelliPAP.

Just speculating, but if I were Product Manager at DeVilbiss and coming up with an oximetry add-on for the IntelliPAP, I would probably do my best to; (a) insure use of a proven product, (b) leverage others in the industry who had gone before (sort of the same as 'a'), and (c) try to give customers a simple migration path by allowing re-use of as much equipment as possible (lower the cost to switch to my product).

Now - please note I admit this is pure speculation, but since I am not a big believer of coincidence, I tend to think there may be a reason both Resmed and DeVilbiss use the same model of Nonin oximeter.

BTW - you can get a pretty clear photo of the connector for the IntelliPAP by going to our hosts page for: Accessories - Software - Card Readers and Modules - SmartLink Therapy Management Module (or click here -- https://www.cpap.com/productpage/devilb ... odule.html) and look at the 2nd photo of the back of the module (http://c0009431.cdn.cloudfiles.rackspac ... e-back.jpg).

Additionally, I found the ResMed S9 oximeter manual, and the photos and instructions look like this:

P1 Instructions --

P2 Instructions --

Image A --

Image B --

Image C --

Image D --

In Image C, it looks like:

# 1 is the SD card

# 2 is the ResMed proprietary module (similar to SmartLink for DeVilbiss - though SmartLink is for ANY data recording, and the ResMed module is used solely for oximetry)

# 3 is the Nonin XPOD possibly with a unique plug to connect to the ResMed/DeVilbiss modules

# 4 is the sensor/probe (such as the Nonin 8000AA or equivalent)

I see upthread there is some discussion about the connectors from the XPOD to the ResMed. Not sure about the DeVilbiss, but would expect it to be a standard Nonin connector since DeVilbiss - unlike ResMed - has no special part number for the XPOD (ResMed part number, I *think* is 1430055).

If there is a special connector for the ResMed, it would be great if some kind of adaptor might be fashioned.

FWIW

[DHC]

Whoops! In terms of my earlier speculation that DeVilbiss and ResMed might be using the same Nonin XPOD model, I just learned the DeVilbiss uses Nonin model 3011 - and upthread it seems it was confirmed ResMed uses Nonin model 3012 - and they are quite different.

Oh well.

I got it to work. It's a bit messy but it works.

I purchased the following items:
- Resmed Oximeter Adapter (purchased from SleepQuest in San Carlos, CA 650-412-0123) - $275
- Nonin OEM Xpod kit w/3012 Xpod, 8000AA sensor and data format 2 (http://www.nonin.com/documents/OEM%20De ... mation.pdf) = $300
- Lemo Receptacle EGG.0b.304 or other series B 4 pin receptacle (http://www.mouser.com/)- $20

When I recieved the Nonin OEM Xpod Kit I noticed right away the connector will not work the Resmed Adapter but Nonin uses Lemo 4 pin connectors. The end connector off the Xpod lead is a FFF.0B.304 (4 pin)
see image:

After reading in the Xpod technical specifications manual about the wiring I noticed that they really only use 3 (a red voltage, black ground and green serial output) [http://www.nonin.com/documents/Xpod%20S ... ations.pdf]. So I figured that if I could just replace the connector on the Resmed device with a Lemo connector, match the wiring it should work. And it does...

Step 1: Remove the cover off the Resmed Oximeter Adapter and remove the wiring from the circuit board. There is a nut the holds the connector on the housing and simple connector to the circuit board.



Step 2: Melt the solder from the 3 wires connecting to the Resmed plug.

Step 3: Replace with Lemo plug and match up the wiring following this image:
Coming off the Xpod the color wiring is not the same as mentioned in the manual. The Red and Yellow are the power leads and the black is the serial output.. Go figure..

The picture of the Lemo connector is from the back where you attach the lead wires from the Resmed device. There is a red dot at the top of the Lemo connector to distinguish top. You will need very eye sight or a maginfing glass to do this since the connector is so small. Use simple needlenose plyers to crimp the Resmed wires in place. No soldering needed here.

The connector is too big to fit into the Resmed Oximeter housing hole so you can either hold the connector in place with tape or drill out the hole bigger. I just taped temporarly myself.



Done!

Here is the end result of a report off my S9 last night:
