If you are trying to use a Tricaster with Multicam Logger, and it fails to connect, make sure that you have entered the appropriate IP address. of your Tricaster. You can check the IP address simply by clicking on the little "World" icon at the top right of your Tricaster user interface.
If it still does not work, try to enter this url in any browser:
Just make sure to replace the starting IP address by the IP address of your Tricaster. IT should return an XML with the status of the switcher (see sample file attached). If this does not work then there is an issue with either your network or your Tricaster and you should get in touch with Newtek's support.
If this works, and still Multicam Logger can not connect, then create a support ticket and send us the complete logs from the menu "Help > Contact Softron Support..."
