Yes, most modern laptops do not have a serial port in order to save
space. If you don't like radioshack(like I), you can find these
adaptors at many computer stores as well, such as compusa.
If you use a USB adaptor, you need you follow the instructions that
come with it for installing drivers if needed.

Not sure what you are getting at here, but USB and RS232(serial) are
completly different port types. Further details are not needed to et
this working, but I can say that if you attempt to wire a usb port to
your intelliscope with just wires, you do not risk damaging your
intelliscope, but you do risk damaging the USB port on your laptop.

Hmmm, not sure what you were trying here, but for others, don't do
this! You do risk damaging a laptops parallel(printer or LPT) port if
you try to connect it to the intelliscope. Besides, it won't work.
Although it is possible to have a serial port with a 25 pin connector,
I have never seen it on a PC more recent than a 486. If you have at
least a pentium, there is approximatly 0% chance of having a 25pin
serial port. In otherwords, if you have a 25 pin port, it is a
parallel one, not serial. Serial is a 9 pin. If you don't have it,
then you don't have it, use USB.
For the majority of people out there, the apropriate thing is to
purchase Orion's cable, then if you do not have a serial port, use a
USB to RS232 adaptor.

With ECU do the following: (from a prior post)
Step 3: Setup scope as usual with object locator. Connect serial cable
to smaller connector on the object locator. The other end of your
serial cable goes to a open port on your pc. (If you don't have a
serial port, you could try one of those USB to RS232 dongles)
Step 4: Align the object locator as usual as described in the Orion
manual. Now you can use the object locator as normal.
Step 5: Start up and configure ECU. Under the telescope menu select
"telescope type and general settings", then select telescope type "Orion
Intelliscope Object Locator". The default settings (including the
encoder setting) are automatically inserted. (if you mess them up, the
encoder resolution for both is 9216 with the azimuth direction being
Step 6: Enable the telescope interface in ECU, performing it's alignment
routine. (Telescope menu, "enable telescope interface") You may wish
to change the default alignment stars first by selecting the desired
star, then in the telescope menu, select alignment stars, then 1st or 2nd.
Step 7: When enabled, you will need to perform the alignment procedure
for ECU. I find it is easier if you use the same stars in ECU as you
did with the object locator. I always used the 2 star alignment, and
used the +90 setting(with the tube pointed up just like with the object
Now you should be working!

There are two benefits in my mind. First, you get a chart view. With
the object locator, you need to cross reference manually with a print
chart if you want to see where you are, or what is nearby. Second,
you can have a larger database.
I use it by using ECU to scroll around the chart, and pick the object
I want. Then I just move the scope until the cross hairs are pointing
at my object(using zoom out and in as appropriate to see enough of the
chart). Alternatively, you can select the object, and press the
button for goto, and a popup window will appear which functions the
same as the finding method with the object locator. Move your scope
so the numbers are zero.

To double check, align your locator and find an object or two to know
that it is aligned good.(this isn't really needed, but is a good place
to start when having problems) Then, align ECU with a 2 star
alignment and the +90 option.(+90 is vertical) When done, make sure
the chart view shows the cross hairs on the star you finished the
alignment with. If so, point the scope back to the first alignment
star, and again make sure the cross hairs in the chart view point at
the correct star. If this isn't working you must be doing something
different in ECU alignment. Perhaps you are not pointing at the stars
you think you are, or perhaps you have ECU configured for something
A couple more points:
You need to provide location information into ECU(like any planetarium
program). If you cannot find your locations lat/lon, use the nearest
city, and you should end up close
the +90 setting is relying on your pointing the scope vertical. by
moving the tube up agaist the stop, you are not necessarily pointing
vertical, just perpendicular to your ground. I have never had any
problem, and I've never bothered leveling my base.
If you find that the setup is close, but not perfect, these things
might be good areas to work on.

2000 is not correct. It must be set to 9612.
