AbstractA research project investigating microwave radio frequency propagation in a 500 mile link across the Gulf of Mexico requires a remote-control process to command microcontroller-based devices including power control modules and antenna feedhorn positioners, and to telemeter system parameters back to the operators. The solution that was developed is a simple, webserver-based user-interface that can be accessed both locally and remotely via the internet. To interface the webservers with the microcontroller-based devices, a polling protocol, based on MODBUS, was developed that provides an efficient command and telemetry link over a serial RS-485 interface.
