DeepSkyDad AF2 driver is included with libindi >= 1.7.6 Under Ubuntu, you can install the driver via:
sudo add-apt-repository ppa:mutlaqja/ppa
sudo apt-get update
sudo apt-get install libindi1
Listening to your feedback we developed a next generation autofocusing unit with WiFi connectivity and optional accessories - wired hand remote controller and temperature probe. Now even manual focus changes using your mobile phone/tablet are so simple that even a toddler can do it (check our Youtube channel for a demonstration on a prototype unit). At the same time it is also retaining mounting compatiblity with our older units, so upgrading to AF2 is as simple as swaping the units - no need to change mount adapters or belts.
You may set pre-defined presets for common focuser positions in the Presets tab.
Connect to the focuser using a USB cable. The connection type is serial and by default the port is set to /dev/ttyUSB0. The default baud rate is 9600. If you change the default port, save the changes by going to the Options tab and click Save configuration.
After establishing connection to the focuser, you can use the focuser control in the INDI control panel directly to move and sync the focuser. Alternatively, the focuser can be used in any INDI compatible autofocusing application.
The options tab provides several settings to tune the operation and performance of the focuser:
Coils mode: there are some scenarios when coils can be turned off after a period of time (e.g. manual focusing via software). But generally, we recommend you to use Coils mode "Always on" for autofocusing procedures, as turning the coils off results in lost position of the motor. Additionally, if coils are turned on at all times, motor holds the focuser position and prevents slipping.
With holding current set to 100%, motor can get a little warm after a while.
