Frequently Asked Questions (FAQ):
How do I add a new connection?
You can add a new connection by going to File>Settings>Add Task and clicking the Add Connection button.
I’m trying to add a device/request/write and I keep getting a “Please select a connection/device” error. What do I do?
When adding a device, you must highlight the connection you want to add the device under from the list of connections. The same goes for adding new requests or writes; you must highlight the device you want to add to first.
Where can I find a log of my session after I’ve closed my connections?
The log.txt file can be found in your base installation folder.
