where to buy a resmed serial adapter ?

[peartree]

Hi,

I need to buy a Serial Adapter (part code 22201) to my Resmed S8 Autoset machine, i've googled a few links but i didn't find the serial adapter.

Can someone recomend a supplier (online or/and store) ?

Thanks

If you are talking about the customized adapter that has one end connected to the machine and the other has a serial connector, I would try your DME or ResMed site. I got mine from my DME. If you are talking about a serial to USB adapter you can buy it at any computer store as Gerryk suggested or for example at the following link: http://www.usbgear.com/USB-Serial.html.

Another option would be the card reader and than you don't need the cable.

Gerry,

The S8 doesn't take a std null modem cable. It requires a special Resmed cable that is durned expensive (for what you get). IIRc the Resmed
USB serial cable is only marginally cheaper than the Resmed datacard reader. So it becomes a toss up as to which one is the better value.

(I settled for a Reslink at $160 & that uses an industry standard card that many computers can read without needing special readers or
drivers (or just a cheap less that $20 reader). Reslink uses a SmartMedia card & holds many more nights data & much more detail than the std Resmed (narrow) datacard.

What does a smartmedia card look like ? ----> http://www.allmemorycards.com/smartmedia-card.htm

Gee imagine that, Resmed gouging the folks who own their machines.

Hi Everybody,

Sorry Long text , I need real help here.

I'm not looking for a null serial cable or even USB-Serial converter.

My CPAP machine (Resmed S8 Autoset Vantage), does have an option to buy an adapter (Serial Adapter part code 22201) or (USB Adapter part code 22203).

I know that the price of the serial adapter should be arround $75. But i don't know where i can buy it.

Darotem mention two options:

1) resmed website: i don't see an option to buy, or even to request a quote.

2) my DME: i don't think they will help me. I'm really disapointed with the away the cpap machines are sold or the connection between doctors/machines/hospitals etc.
My family doctor recommend to do a sleep study, after 2 studies (one without a machine and another with a machine) a fews days later, i knew from my insurance that i had a doctor (specialist) assigned with some bills charged (related to the sleep study), and a requisition for a cpap machine was done by the specialist doctor.

After a few more days finally i met the specialist doctor, who told what i've alreay known from my (insurance online account) he gave me a machine to take home, everything was arranged, no choices (besides the mask).

Surpriselly his office represents the Resmed brand. I went home with a cpap machine (without the clinical manual and minimum information about the machine or options).
I've discovered later that i'll need a prescription to buy a second cpap machine, this is really funny ... When i asked about a prescription to buy a second cpap machine (traveling) he said don't worry come here and i'll get you a nice cpap machine.

But making the story short, i don't think they will sell me the adapter. I went to 2 appointments with specialist and i took the memory card, he printed the data, brieflly looked, archived, and talked the same stuff, and the end said: I need to see you in a month. After 2 appointments i stopped booking more appointments.

Q: Why a need a Serial Adapter + serial null modem VERSUS a resmed memory reader ?
A: I whould like to explore the option to monitor real time the cpap machine, instead of taking the memory out, going to the reader etc

Q: Why online VERSUS offline data analysis ?
A:

Currently i have a problem with my sleep/cpap machine. During my sleep i wake at least 1, 2 times (going to the bathroom, or drinking a little water/dry mouth (i have a humidifier) ) .
i'm doing this things without full awareness, and what happends is: i stop the cpap machine, i take the mask out, do whatever i need to to, i go to bed, and i don't put back the mask/ or i forgot to press the start again.

The result is 2-3 hours sleep with the cpap machine. This is not good.

What i would like to do is to setup a Laptop with the software, a online link (Serial Cable + Serial Adapter) and assign an alarm when the machine stops working for a specific period (means i went to sleep and i didn't put the mask and/or pressed the start button).

Offcourse there are some issues to solve: software limitations (ResScan) could not have the options (alarms, online monitor).
I'm a software engineer (desesperated to have good sleep nights), it's more easy to me to "reverse engineer" what is going on a serial cable, and build some simple application to monitor my resmed machine.

I think this functionality is so simple that should be available (built-in) in the cpap machine, it's like a alarm's snooze button, when you press it stops the machine for a short period (break) but than activates again later, if the mask is off, and with the "leak alarm on" a alarm is raised and the user needs to put the mask on.


The real QUESTION is where i can buy the Serial Adapter ? Can somene help me here ?


Thanks for reading,

FWIW i have the USB adapter on sale at cpapauction.com - priced at $60 plus shipping. i had to get it from australia, cost something like $75 plus shipping - couldn't find it in the states! i saw you want to do real time monitoring - i don't believe you can do that without the reslink adapter, which i believe is about $1k - reslink will let you monitor oxygen, and give you the high resolution "shark fin" breathing - breath by breath. ResScan (required for the adapter) will give you general averages, i.e. you can't see breath by breath but it claims it will give details within 10 seconds.
i would personally shy away from the serial adapter - i'd go either USB or use the card option - serial (okay, let's get fancy - RS232) used to be THE method of transferring data - modems, my telescope, etc. - now it's a dinosaur, and my 2 year old notebook doesn't even have a serial interface (it has 3 USB interfaces, and i have bought USB to Serial adapters -- but why?
hope this helps...

After doing a quick search on the net it looks like you can hardly buy the serial cable in the US. Found one source for about 90$. It can be obtained in Australia but as I have said before I believe the USB adapter or the card reader would be a better option and probably cheaper.
Regarding on-line monitoring, I can't see the use of it. I am checking my numbers daily on the machine's LCD and download from the machine to the computer every five days. By doing so I can have all detailed data for every night. Of course you can't monitor your oxygen unless you have an oxymeter but you can get a bunch of useful data.

Gary,

There is a lot of confusion about what a Reslink module is. The Reslink doesn't include SpO2 unless you buy the add-on SpO2 adpater. That is priced seperately but many places bundle the lot & all up ask around the $1000 mark BUT no one needs to buy 'the lot'.

The base Reslink is a clip on unit that has a SmartMedia card rather than the specialised Resmed narrow datacard. SmartMedia cards can be read by any computer with a SmartMedia slot or a sub$10 SM reader unit. I paid around $160 for my Reslink. Reslinks can sell at higher prices and that is where some smart shopping comes in. The Spo2 plug-in is expensive & normally sells around the $450-$500 mark.

thanks DSM; i had thought the ResLink was $1k - once i saw your post and that it was in the $160 range i actually sent you a PM asking where it was available for $160 - that might prompt me to buy the thing and either keep or repurchase the software -- thanks!

Slinky,

#2 FOUND the contact - no need to follow through on the below req DSM

#3 Also the actual cost was $189 & not $160 (I mentioned it was a guess at the price but in finding the original emails I see it was $189)

#4 PMs sent to those who asked (I won't post the sellers details directly here out of respect for our hosts as they are sort of a competitor to cpap.com)

Need your help here - who was it we go the Reslinks from ? (I would have to dig through months of emails to find the info)
If you don't have the answer readily available I'll do the search

Cheers & thanks
