Gemini

Gémini 2 system






How to load a catalog into the Gemini :

Unzip the catalogs you are interested. The catalog use in the Gemini must be ".guc" type.

Using an ethernet cable between Gemini and your computer :
  1. establish a fixed IP to your computer (eg 192.168.0.1)
    Control Panel / Network Connections / network connection properties / TCP IP
  2. use your web browser by connecting to the address 192.168.0.111
  3. in the new window : username = admin and validated without password
  4. Gemini homepage appears
    click on "SD Card" then "HCFirmware"
  5. select the new catalog (click on Browse, select .guc file)
    and press Submit
  6. on the hand controler, go to Menu, HC, and press Dowload
    a scrollbar appears ... the new catalog is load
Now you can use it


You can also transfer catalog into the directory "HCFirmware" by using a FTP program
  1. paramatrers software (see above)
  2. connect the Gemini to your computer
  3. submit catalogs in Gemini "HCFirmware" directory
  4. on the hand controler, go to Menu, HC, and press Dowload
    a scrollbar appears ... the new catalog is load









Some catalogs :

With these catalogs you can goto the object and have some information about it

Create your own catalog

Use a text editor
Write your data as follows:
The Right Ascension is in the form 00:00:00 (6 digits separated by ":") and DEclination as +00:00:00 (sign (+ or -) 6 digits required separated by ":")
A maximum of 20 characters for the name and 50 for information (this can vary slightly depending on the characters used)
Save in text format and then rename your file with the extension ". GUC"

Comments:
French accents (à, é, è, ê) are taken into account
Comma can not be used because it serves as a delimiter (between the name, position and information) for the Gemini
Greek letters are considered, you must write in the following way:
