INDIGO Control Panel is a generic INDIGO client. It can be used to connect to the remote or local INDIGO or INDI server and read or set any of the device driver properties including BLOBs and images. There is a similar application for iOS running on iPhone or iPad if you have one.
Using this application is pretty straightforward. Application will discover any available INDIGO server in a local network automatically, but you can also add remote INDIGO or INDI server or servers in Preferences at INDIGO Services pane.
In the left pane you can see all available devices. Grey indicator means disconnected and the green indicator connected device. You can connect or disconnect by opening the Connection property (usually in the Main Control group) and clicking the Connect or Disconnect checkbox.
Other groups and properties are device driver dependent, read Standard INDIGO properties or Standard INDI Properties article to learn more about some of them. The grey, yellow, green and red indicators in front of the property name corresponds to idle, busy, ok and alert property states.
To run INDIGO Control Panel you need Apple Mac running macOS El Capitan or later.
