This guide will help you get the Ethernet connection working
with the ASCOM Gemini.net driver. Please note that this guide now
has been added to section 5 of the

Gemini.net ASCOM driver</a> manual.

Advantages of using Ethernet over other connections interfaces.
<ul><li>Able not only control the mount with Ethernet, you can also guide
through the same cable. The UDP protocol used is much faster
than USB, provides less load on the computer, and provides for error
correction. You can guide and control the mount with USB or
RS-232 (one cable) but it does not provide for error correction and
actually loads the computer with an additional driver. </li>
<li>If UDP is selected. The speed is extremely fast,
even faster that an USB connection.</li>
<li>The ASCOM Driver and ASCOM provides for having many clients
connected to the telescope at the same time. You can have
TheSkyX (using the X2 Plugin), MaximDL, PHD guiding using pulse
guiding, all connected at the same time, plus many more of ASCOM
compatible programs.</li>
<li>Guiding through the ASCOM Gemini-2 Driver provides many
advantages:<ul>
<li>The guiding is Synchronous - which means two-way, the
Gemini-2 will acknowledge the guiding commands. Using the
Guider input this is not possible.</li>
<li>The program can tell the mount how much to guide, instead of
a fixed guide pulse. The Guider input relies on an
interrupt for the RA signal, but a timer for the DEC, which
means DEC guiding pulses possibly can 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 guider output plug.</li>
<li>Less cables means less chances of a ground loop, which can
cause possible damage to electronics. Ethernet has a built
in transformer to help isolate it's input, thus preventing
ground loops.</li>
</ul>
</li>

<span class="style3">Before we get started, You must be able to access the
<a href="http://gemini/" target="_blank">web interface</a> with a web browser. If you
cannot do that, then you will not be able to get the ASCOM Gemini.net
driver to connect via Ethernet. Clicking on the address above will
test your Ethernet connectivity. (The address above uses
<a href="http://gemini/">http://gemini/</a> and only works if netbios is
working on your system. Otherwise use the IP address shown on your
hand controller (Menu-->System-->Network-->IP Address.) The default is
192.168.0.111. You must have the Gemini-2 powered up also. This
is only a test to make sure the Ethernet connection is working properly.
It has nothing to do with the actual ASCOM to Ethernet Driver.</span><br />
<br />
If you passed the above test, lets get started. Now these instructions only cover configuring the Ethernet in the ASCOM Gemini.net
driver. You will need to see the
<a href="Gemini2_drivers/Gemini_Telescope_Net_Installation_and_Operation.pdf" target="_blank">HELP</a> guide included inside the ASCOM
driver which covers most everything else. Just use the HELP or
Press F1 - It will
bring up the help guide as a PDF. To find it select Setup, the Help is
displayed in the third group down. Selecting it will bring up the
Help PDF file also.</td>

The above setup menu is what you will get if the Gemini-2 has not been detected. Notice you can still see
Asynchronous Pulse Guide and Precision Pulse Guide.<br />But if the Gemini-2 has been detected, you will get the menu below. Asynchronous Pulse Guide and Precision Pulse Guide, are not shown. This is because the Gemini.net driver sets them automatically.

<li>(Gemini-2 only for this step and beyond.) Now click on the

If you cannot connect to the Gemini.net ASCOM driver with the NetBIOS
Name Resolution box checked, as on the left picture above, then that probably means that you do not have
<a href="Enabling_netbios.html" target="_self">NETBIOS
enabled</a> or working. That really is the best solution.</li>
<li>
But if you cannot use NETBIOS, then uncheck NetBIOS Name Resolution, as
in the picture on the right, and in the
<strong>"Gemini IP address"</strong> block enter the IP address of the Gemini-2
Telescope controller as shown on the Gemini-2 hand controller or the
Gemini-2 network web page. Do not uncheck "Use UDP port" or change
the port number. Do not change
User name or password. Keep Bypass proxy checked, and then
click OK.</li>
<li>
Please note that some firewalls or Routers might block Port 11110.
If they do, then you need to unblock them. There is no way that I
can cover how to do that. You will have to refer to your
firewall or router manual to do that.</li>
