How do I find the Windows Device Manager to see my USB to Serial Adapter port
Every Windows operating system uses a different succession of multiple mouse clicks
to eventually end up at the Device Manager. Why Microsoft chooses to make things
so difficult for the end user is beyond me. However, there is a shortcut that
can be used on any Windows machine to access the Device Manager directly, and
at any time. It's this simple:
1. Hold down the Windows key on
the keyboard, and press the "R" key.
2. In the textbox that appears, type:
devmgmt.msc and Click
OK, or Press Enter.
Bingo, you're in the Device Manager! Once there,
Double Click on:
"Ports (Com & LPT)"
and you'll see the Com Port assignments for your USB to Serial Adapters,
printer ports, and/or serial ports.
DataMaster Sportsman Computer FAQs
What diameter of driveshaft will the 12 point ring fit? I think mine is 3 or 3.5".
How does it attach? Is engine rpm determined from the MSD tach output? I have
Altronics DRT with G-time. The car will 60' within .001 and reactions can be within
.005 but the numbers on the DRT vary by as much as .3. From one day to the next
my reactions went from .010's to .040's and I know I was not late but the DRT
still shows about the same. Baffling information. My laptop only has a usb port.
Will that work? Thank you in advance.
Actually, it's not baffling information, the data is just telling you that the
device is not working. And, unless you have multiple pickup points and a high
speed CPU, like our DataMaster, there is no way it can work, because every time
you stage the car the pickup is in a completely different position. None of these
devices, or any data recorder on the market today, are as accurate as the DataMaster,
but it's a great way for them to get your money!
gives you a highly accurate Vehicle Reaction Time (VRT) with .001 accuracy, which
allows you to see if the car is repeating during roll out and hooking consistently.
Personal Reaction Time (PRT) or Driver Reaction Time (DRT) cannot be measured
without being able to "read" the tree. You can, however, subtract the VRT from
the Reaction Time (RT) on your time slip to see if your PRT is consistent, which
is what you seem to be looking for.
If you have a dragster with a coupler,
the ring goes on the female half of the coupler. Otherwise, the ring goes on the
machined surface of the pinion yoke directly in front of the pinion seal. It depends
on the type of rear and pinion yoke manufacturer what diameter ring you'll need.
There are several different sizes available, and we can machine many custom configurations.
The RPM square wave signal is provided by the MSD Tach terminal. A simple USB
to Serial adapter is used if you do not have a true hardware serial port.
ET Prediction Software FAQs
Does this software work with a set of gauges and a computer or do I need weather
station also. Will a notebook style computer with 200 memory , 1 gig ram and basic
Microsoft 7 run this. Will it load with flash drive or a disc player. What gauges
do you recommend. My Performaire station died and i need a small size computer
at work so I was hoping to get something to do both.
You can use gauges that measure barometric pressure, temperature, and humidity.
Old style analog gauges are not accurate and do not update rapidly, so digital
gauges are preferred. Ideally, you would want a barometric pressure gauge that
reads Absolute Pressure, not corrected pressure. We have a hand held gauge called
the Digital Pocket Weatherman that is very accurate:
next step up would be a Davis Weather Station because it also provides wind readings
that can be used in the ET Prediction result. Having a solar shield and better
sensors, the accuracy is improved:
Weather Station can be linked to your computer and have the readings go into the
program automatically using the Davis WeatherLink:
notebook computer or laptop should be fine. However, there are some netbook computers
that do not use a Windows operating system. The computer used must be running
at least Microsoft Windows 98, Windows XP, Windows Vista, or Windows 7 Home Edition.
The Windows 7 Starter Edition is very limited. If the computer can run one of
these operating systems, then it has enough resources to run our software. The
installation program comes on a CD or can be downloaded from our web site on the
internet. It can be transferred to a flash drive if the computer does not have
internet access or a CD or DVD drive.
Trailer Station FAQs
is the benefit of having the Di-Pole Antenna option versus the regular 'rubber
duck' style antenna?
A. The di-pole antenna is mounted externally.
If you have the transmitter located in a motorhome , the signal can travel through
the glass and an external antenna is not necessary. However, if you have the transmitter
located inside a metal trailer, the signal would be reduced. Closing the doors
on the trailer would kill the signal entirely. Therefore an external antenna is
mandatory in that application. In any event, the di-pole design doubles the radial
range of a normal transmission, or can be used directionally to 'point' the signal
in a particular direction such as the staging lanes.
