The AltAcc, etc. software was written when the serial port was always there
and never went away. The USB to serial adapter's serial port appears when
the cable is connected, and disappears when it is removed. This old software
isn't set up to handle this. That is why you have to connect the USB to
serial cable, let the Windows recognize it, then set the software to use it.
I have a Prolific PL-2303 USB to serial cable. This cheap adapter works with
Windows XP and 7 and has worked with every program and piece of hardware I
have tried. I did need to download and install newer drivers. I had problems
with other adapter cables.

I am still having issues downloading the Altacc sometimes and it is usually
the port settings. Same with the Control. For once I would like to plug it
in and have it find the port automatically. Seems pretty stupid to have to
go in and line up the port setting every single time. I don't know if that
is the function of the usb/serial adapter or what. When I actually had a
serial port, I don't remember having that problem. I have a Featherweight
Parrot and the interface for that is much better. But then the Altacc and
Control are both dinosaurs compared the the Parrot and Raven.

The best adapter that I could find at the time for my computer was IOgears
GUC232A USB to Serial adapter. Works great with downloading flight data but
will sometimes lock up when using the read live data option. I think it
overloads the buffer but everything else works fine.
I loaned it to Kurt G. at one time and he for some reason couldn't get it to
work properly so it's possible that it won't work on some computers or that
Kurt didn't have the correct port setting.

I'll have to look to see what adapter I have. It's on a 5 year old Dell
laptop in the shop. Actually Ron I got a line on another! :D
I stopped using it when Wayne got me into hybrids ;) I guess people said it
was not optimal for the thrust profile. Or something like that...
Other than not reading out the altitude from the LED, the Altacc, being a
recording altimeter, was actually WAY ahead of its time. Or at least lead
the way. I used to correspond with Konrad Hambrick who did the coding down
in San Diego. You could work the data and find out the CD of your rocket.
THAT is what is missing IMO about the Altimeter Two. It's REALLY handy to
know the real CD of a rocket.
Anyway mounting the Altacc is sooo freakin simple. Arming it is simple.
Everything about it is simple. (Cept reading the altitude!) And though I've
only had about 25 out of a 100 HPR flights using an Altimeter for
deployment, the little Altacc has never failed. And I like that I can test
it easily.

Cheap, yah good luck! Them thar things are collectors items. yuk, yuk!
So which adapter are you using? I did some testing for Scott Bartell way
back when (I did it on my own) and he was very gracious for me putting the
info out from my tests.

Yep! It's the very same. It's an AltAcc 2. One of the originals. I've tested
it with 12v lamps and it's working fine. Then I got a Serial to USB adapter
on my Laptop and made sure I could run the old proread and produce to get
the data out...
I'd love to buy a backup on the cheap. :)
(Cheap = under 50 bucks) :)

Hey Jeff,
That hole pattern in the Ebay sure looks like the same hole pattern as an
AltAcc manufactured by the late Black Sky Rocketry Company ;^)

PS Does anyone remember Delta V Rocket motors or perhaps even want too? To
do so is definitely dating ones self lol

I am sure a few of you remember last weeks flight of the upscaled The Launch
Pad Osiris on an H97-S. 'S' standing for 'Still too long'. :)
To be honest the rocket has flown many times with a recording altimeter.
Over that time I've dialed in the CD on ROCKSIM based on those flights. It
was getting to the point where flights were within 10% to 15% of ROCKSIMs
predictions. So it should have had PLENTY of margin for apogee deployment...
I am not sure what went south. My guess looking at the rail guides is those
guides should have been replaced a long time ago and it expended too much
energy off the pad. It's speculation but the flight was way low for a 5
pound rocket.
Anyway... since the PML tubing was glassed when I built it, I was able to go
from picture 1 to picture 2 one week later... - Now slightly longer and
sporting an Altimeter bay for an Altacc or MissileWorks RRC
