silverlining data cables

[solveforz]

Quick version: can information from a Goodknight 420s be downloaded
without spending $50 on cables?

Some details: I have a 420s and would like to see my data. I can borrow
a CD to install the silver lining software but need a cable. I see that I can
buy the usual RJ11 to RS232 data cable and also a RS232 to USB
converter for about $27 each for a total of around $55 (before shipping
and handling from two places) (like most people I don't have RS232 ports
anymore).

There is also a "modem cable" M-213930-05 but I can't find any
description of what it looks like or does. That is about $32.


Evidently it is possible for a provider to remotely download information
from a 420 and even reset it via a modem. I suppose it is too much to
hope that an ordinary phone cord (RJ11 to RJ11) can run from the cpap
to the modem port on a computer and download the information.

random details: I've had my 420s for several years and it works well
enough for me. I use naal-aire 2 pillows. I have allergies but I just up the
pressure for a few nights if I need to. As long as I can get the flow going I
am good for the night even without a PM decongestant. I like that after
decades as a mouth breather I'm using my nose. My slep doc is great
but I only see him once a year. I prefer to use no more pressure than I
need. My sleep study setting was 8.5 but I've found that I am OK at 7.
I've tried 6-6.5 and from an apnea perspective that seems OK but there is
some snoring which results in pain to my ribs on one side (my wife has
sharp elbows). Lately I've managed to lose a few pounds so I'd like to
see what setting will keep me snore free.

Related question: Is it correct that a fancier machine like an APA or
420SP is less able to give accurate unformation about delivered pressure
at the tube end and also snoring events?

Thanks!

Thanks, I might. As I mentioned, though, most modern computers don't accept this kind of cable so one is out another $24 or so for something like: http://www.pcconnection.com/ProductDeta ... oext=1038A

True, most newer computers do not have a Serial port. However, a Serial port PCI card or a Serial to USB to Serial cable can be added at a low cost.

It's my understanding that either method (with or without an extra sensor tube) will give accurate airflow information.

Some machines are designed to use an extra sensor tube sensing at the mask end. Most are designed to do the sensing at the machine end and don't require an extra sensor line. Either way is accurate. It's just a matter of how the machine designers choose to handle it.

When you fire up Silverlining, its first screen has "modem connection" as an option, But you're expected to dial a number....

My computer doesn't have a serial port, so I did buy a USB to Serial adapter.

Here's a link about a cool way loonlvr ran a long telephone extension line from his 420E in one room, to his computer in another. I did that, too...worked fine. Didn't have to carry the machine (little, though it is) and its power cord to the computer anymore. The phone extension line connected to the download cable at the computer, of course. Wasn't just a long phone line running from machine to a modem on the computer.
