Why can’t I control my stages within ENTTEC LED Mapper using the Ctrl for iPad module?

If you cannot connect Ctrl for iPad to ENTTEC LED Mapper (ELM). Firstly, check your iPad’s network settings to ensure that both your iPad and ELM PC are in a similar IP range with the same SubNet and Remote HTTP is enabled within Settings -> Remote within ELM (a SubNet of 255.0.0.0 is recommended on both your iPad and ELM PC). – To confirm connectivity you may wish to ping your iPad from your PC's command prompt.

Ensure your HTTP patch you are using for the ELM module is raw: i.e. http://10.0.0.10:80/

To rule out anything network related, create an HTTP fader to control ELM and ensure ports are not being blocked with connectivity and firewall settings.

If this still doesn’t work, try a different port other than 80 to communicate over (update ELM’s HTTP port to reflect this).
