<li>Go to the <a href="http://www.ascom-standards.org/index.htm">
ASCOM Standards Site</a> and find the "Download" button (usually inside a box on right).
This should be the latest version of the ASCOM
Platform. Download and install the platform on your computer. DO NOT INSTALL
USING RUN AS ADMINISTRATOR.
You can read about ASCOM Release 6.5 here:
<a href="https://github.com/ASCOMInitiative/ASCOMPlatform/releases/tag/v6.5Release">
ASCOM Platform 6.5 Release</a><span style="word-spacing:normal;">.</span></li>
<li>Next you will need the
<a href="javascript:localURL('Gemini2_drivers/GeminiTelescopeInstaller(1.0.75.0).exe')">Gemini ASCOM driver</a> and install it.
It should be version (1.0.75.0). DO NOT INSTALL USING RUN AS
ADMINISTRATOR. This will also be the
latest version released. Please note that this driver requires .NET
4.0 Framework. You can
<a href="https://www.microsoft.com/en-us/download/confirmation.aspx?id=30653">
download .NET 4.5 here</a>. Windows 10 has .NET Framework 4.6
built in. (it might need to be turned on.)</li>
<li>If you have never installed or setup the Gemini.net ASCOM driver then
here is instructions for

first time Setup</a>.</li>
<li>If you are going to use Ethernet to connect your Gemini-2 to
your computer here are
<a href="configuringEthernetASCOMdriver.html" target="_self">
instructions</a> to do that.</li>
<li>** If you install the ASCOM programs as ADMINISTRATOR you will
have to run any program you want to connect to them as
ADMINISTRATOR.</li>

Why use the Gemini.net ASCOM Driver with the Gemini-2: (or Gemini-1)<br>
<ol>
<li>The Gemini.net ASCOM Driver implements a standard ASCOM interface to contol telescope mounts. Many software packages support this ASCOM interface allowig you to try and use many of them.
The ASCOM Driver is a convenience and, in many cases, a requirement.</li>
<li> If you need to share the connection to Gemini across two or more software packages, ASCOM is the only game in town today.
</li>
<li> Moreover, nearly all astronomical software from small companies or independent developers only use ASCOM to
control astronomical equipment. This enables them to concentrate on one implementation that works across various
equipment brands, and avoids the cost of developing, testing, and supporting separate custom interfaces. </li>
<li> You can control the mount via a Serial Cable, a USB connection
or Ethernet (Preferred). (Gemini-1 Serial Only.)</li>
<li> You can guide and control the mount using the same Ethernet cable.</li>
<li>When a UDP Ethernet connection is used, the speed is extremely fast (faster that a USB connection) while minimizing the load on the computer.</li>
<li>The Gemini.net ASCOM Driver allows multiple clients
connected to the telescope at the same time. The Gemini.net
ASCOM driver is a HUB.</li>
<li>You can use other ASCOM drivers to control focusers, cameras, observatory, etc., and the Gemini.net ASCOM Driver to control the mount at the same time.</li>
<li>Guiding through the ASCOM Gemini-2 Driver provides many
advantages:<ul>
<li>The guiding is synchronous (two-way):
Gemini-2 will acknowledge the guiding commands, something that is not possible when using the Guider ST-4 port.</li>
<li>The Autoguider program can tell the mount how much to move,
instead of sending fixed guide pulses via the ST-4 port. The Guider ST-4 port relies on an
interrupt for the RA signal, but a timer for the DEC signal. This
means that DEC guiding pulses could be missed if they are too
short. This problem does not exist when using the Ethernet port
to guide.</li>
<li>No guider cable is necessary, therefore almost any camera
can be used to guide as long as you have a driver for the
camera. The camera does not need a guider output plug.</li>
<li>Less cables means less chances of a ground loop, which can
cause possible damage to electronics. the Ethernet connector has a built
in transformer that isolates its input and prevents
ground loops.</li>

As a small example you can have TheSkyX, MaximDL, PHD guiding using pulse
guiding, all connected at the same time, plus many more of ASCOM
compatible programs. A few of the programs that use the ASCOM Driver to connect to the Gemini
1 and 2 are:
<ol>
<li>The SkyX</li>
<li>MaximDL</li>
<li>PHD2</li>
<li>Sky Tools 3</li>
<li>Stellarium</li>
<li>Carte du Ciel</li>
<li>PemPro</li>
<li>Sequence Generator Pro</li>
<li>Many others. See if the program you want to use supports ASCOM.</li>
