Sample of several ways to connect the Gemini-2 via Ethernet
Sample of several ways to connect the Gemini-2 via Ethernet
  1. Options 1 through 4
    • The top three illustrations are for direct connections. If either the router or switch has a Gigabit (10/100/100) speed connection it does not matter where a straight or cross-over cable is used.
    • The bottom illustration are for indirect connection through a Wifi bridge using a WiFi Adapter.
      Such adapters are described in FAQ Question  #3  There are many brands of what is commonly called Gateway/Bridges.  Just make sure that it has a Bridge mode.

Options 1 through 4


  1. Option 5 illustrates how you can use a single USB output from you computer to connect your cameras and also the Gemini-2 using it's Ethernet port. It adds a USB to Ethernet adapter into the mix so that you have the best of both worlds with only one USB cable from your computer.


Option 5


  1. Option 6 illustrates how you use two wired computers, (maybe using teamview or Remote desktop) to control the Gemini-2 plus cameria and focuser. a single USB output from you computer to connect your cameras and also the Gemini-2
    • This requires the remote computer to have two hardwired Ethernet ports.  Most computer so not have a second hardwared Ethernet port. We can simulate a second hardwared Ethernet port using a USB to Ethernet adapter.using  One suggestion is the Pluggable USB to Ethernet adapter. it's Ethernet port.
    • Note that a Powered USB hub is shown.  This is because most USB to Ethernet adapter draw the full 500Ma that a USB port can supply.  Also most small laptops do not have 3 fully powered USB ports, as would be required, if the HUB was not used,


Option 6


  1. Option 7 illustrates how you use computers two connected via a Wifi network, (maybe using teamview or Remote desktop) to control the Gemini-2 plus cameria and focuser. 
    • This requires the remote computer to have one hardwired Ethernet port and one Wifi port.  Most laptops fall into the catagory.
    • The Ethernet cable that connects the remote computer to the Gemini-2 can be a normal Ethernet cable if the Ethernet port on the laptop is rated as a Gibiport speed port.
    • It the Ethernet port on the remote computer is only a 10/100Mhz speed Ethernet port the a Ethernet crossover cable will be required between the remote computer and the Gemini-2.
