Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A control system, comprising:
a microcontroller including a memory; and
executable code stored as firmware in the memory that, when executed by the microcontroller, configures the microcontroller to:
generate a frequency shift keying (FSK) signal including a command for a remote device;
condition the FSK signal according to operating characteristics of the remote device and characteristics of a communication channel coupling the control system to the remote device to generate a conditioned FSK signal;
transmit the conditioned FSK signal to the remote device via the communication channel;
determine a time base of a message received from the remote device;
determine whether the time base of the message received from the remote device varies from a time base of the control system; and
scale the FSK signal to generate the conditioned FSK signal as a frequency scaled shift keying (FSSK) signal based on a variance between the time base of the message received from the remote device and the time base of the control system.
