Can't connect APM to APM planner

I’ve tried to connect my APM to APM planner. I’ve successfully installed Firmware and tried to connect APM (press connect button). But no one parameter have changed and “mode” light still red. What should i do ?

Did you remove modemmanager as instructed?
Do you know that it has any firmware on it, and that the baud rate is 115k?
