Check power, cable, port availability and driver state.
Rotators, radios and SDR
Verify power, transport, address, baud rate, protocol and manual stop controls before connecting equipment.
Verify transport, address, baud rate and protocol version.
Read state first, then test small movement or receive-only tuning.
Set mechanical limits and retain manual stop or independent power-off.
Accuracy and safety
Pass results depend on orbital data, location accuracy and time. Follow local radio rules and keep an independent way to stop or power down moving equipment.
