- a page that shows the current state of the mount
- a small hand control program that gives limited control and Go functions.
- GOTO Coordinate Input, Physical Position Park/Sleep/Wakeup and reboot mount, plus Manage
parking modes, PEC control, Classic Hand Controller mode, (Note: this
has to be either in Photo or All Speeds mode for the mount to auto guide)
and tracking speed selection.
-(Previously called Objects) This is a list of all the
targets above the horizon in all the catalogs of the Sky. It also provides a Go-To function.
Mobile Hand Controller
- this interface was written by a third party, (who has moved on to building his own
mounts). It provides an interface that sizes itself to a mobile phone or tablet and was
designed to work from either Android or IPhone devices using the web browser on these devices.;
It does provide for using the built in GPS of these devices to update the site info.
Because this is wrote by a third party you use it at your own risk.
- This is where the mount Parameter setup, including mount design, mount type, Gearing, Slew,
Move, and Centering Speeds are entered. Also the Safty Limits canbe set on this page.
- This is where you can enter the time in either Local time or UTC. You can also define the
sites that come up on the hand controller. There is also a button to Query a GPS receive if it
is connected to serial Port one. You can also Query an
external NISP time server to get time and date.
- This is where you can see the model Parameters, change the current model, and store and retrieve
models from the micro SDcard inside the Gemini-2 main unit.
- here is where you can see the contents of the micro SDcard inside the Gemini-2. You can also
upload files into the micro SDcard here. PLEASE NOTE: There is no delete function to
erase a file, once it is uploaded to the micro-SDCard.
You can also format the complete micro SDcard. You really need to know what you
are doing if you use this function.
If you do that only FTP functions are left to be able to then update the card, or the
Gemini Firmware updated can also still update the card. The other alternative is to
remove the card and use a mico-SDCard reader writer to access it's contents.
- This is the Flash memory menu. You can upload a new NewGem.bin file using this menu. That is all
it allows you to do. It does make sure the file is at the root of
the micro SDcard. The SDcard menu will also let you do that, but you
have to select the location to load it to.
- This is where you can see and set the current and stored setting for all networking parameters.
- This is where you can add a password to the Web interface.
- This is where you can set the baud rate for the serial ports.
Please note that Serial Port Baudrate need to be 57600 if the hand
controller is going to work.
- This is the TCP Socket status page. It is read only.
- This page shows the Power Supply voltage and the Internal Lithium Battery voltage (a CR2354
replaceable battery) Also show is the pin status of all the ports.
To see the pin status Periodiclly you will have to select Periodic
Port E usage can also be defined on this page. To use
any of the Port F pins, they have to be checked. But it seems that
this state is not retained after leaving the page.
- This is the page where you can see what current firmware is installed. Please note that we
normally go by the build date to determine the firmware version.
This menu also allows for flashing the NewGem.bin file into the main
processor. The NewGem.bin file contains all of the Gemini-2
instruction and code. There are many other files that reside on
the micro SDcard, and in the Internal SRAM (battery backed up) that must
to there for proper operation of the Gemini-2. You can also store
the SRAM contents into the micro SDcard for later retrieval.
- This page allows you to see the Motor State and setting, and
allow you to set the Thresholds for the
warning messages shown on the hand controller. Please be very
careful when you set these setting as you can damage the motor's or
motor drive circuits, is set wrong.
Serial Command Set
- This is a listing of all the serial commands that the Gemini-2 accepts, through it serial port, USB port, Ethernet Port,
and from the Graphics Hand controller.
Videos By Scott Losmandy
- The 15 videos that Scott Losmandy produced to show how to use the Gemini-2, Position the mount to CWD, and use the
Polar Scope Illuminator are stored on the mico SDcard, and with an
external web browser connected through the ethernet port, they can be
view directly from the Gemini-2 micro SDcard.
- Please note that at the bottom of each screen is a
selection for Night mode - Day mode. Click night mode on the above
image to see an example of what night mode would look like. In
this tutorial, this is the only page that has a night mode screen shown.
The Gemini-2 has night modes for all screens.
On the bottom of each page, except "Hand
Control (HC)", "Mobile Hand Control (MHC)", "Serial Command Set" and
"PAA Tutorial" there should be a "HOME" button, use that to return to
