Network

All Gemini 2 parameters and many observing functions are accessible using a built-in

web interface. In order to use the web interface, you will need to make a network con-

nection to your computer. This is most easily done using a cross-over Ethernet cable

directly between Gemini’s Ethernet connector and your computer’s network connector.

Alternatively, you can use standard cables between Gemini and an Ethernet hub, and

between your computer and the hub.

IP Address: In order to successfully communicate with your computer over the net-

work, the Gemini 2 unit must have an IP address on the same subnet as the computer.

There are several ways to do this depending on how you connect to a network. The

following sections describe these methods.

Direct connection (typical conﬁguration in the ﬁeld): If you use a cross-over Ethernet

cable to directly connect your computer to Gemini, you’ll need to assign both the com-

puter’s Ethernet port and Gemini to IP addresses on the same subnet manually. This

assumes that your computer is not running a DHCP server on the network port. If

Gemini doesn’t get an IP address assigned by DHCP, it will use its stored value

192.168.0.111 by default.

1. Use a cross-over cable to connect Gemini 2’s Ethernet port to an Ethernet port

on your computer

2. Use the appropriate tools on your computer to assign a static IP address to the

computer’s Ethernet port. The address should be in the form 192.168.0.xxx

where xxx is any number between 1 and 254 except 111. Set the subnet mask

to 255.255.255.0. On Windows, you can do this from the control panel. Look

for an option to change network connections. Refer to your OS documentation

for speciﬁc instructions. On Macintosh OS X, open System Preferences/Internet

& Wireless/Network to edit network connections.

3. Power on Gemini and attempt to access the web server at http://gemini or

http://192.168.0.111. If this doesn’t work, use the hand controller menu to

ensure that Gemini’s IP address is 192.168.0.111 by selecting the menu-

>mount->network options. If it is not set to that address, you can either

change your computer’s IP address to match Gemini’s subnet or you can change

Gemini’s IP address to 192.168.0.111 (preferred).

4. Gemini uses NetBIOS name resolution so that you don’t need to type the IP ad-

dress into your browser. If you haven’t already done so, enter http://gemini in

your browser to access the web server. The username is “admin” and the de-

fault password is blank.

Network with DHCP support (typical conﬁguration for most home networks with a

router): If you are connecting Gemini to an existing network through a switch, hub,

router or wireless adapter, and there is a DHCP server on the network, use this proce-

dure. Gemini will be assigned an IP address by the DHCP server. It is important that

your computer also be set to either use DHCP to get an IP address, or use a static IP

address on the same subnet.
