Claim 0:
1. A method implemented by a control system for communicating with a remote device comprises:
determining a frequency of operation of the remote device;
determining whether the frequency of operation of the remote device varies from a programmed frequency;
determining a frequency scaling factor based on whether the frequency of operation of the remote device varies from a programmed frequency;
generating a frequency shift keying (FSK) signal;
scaling the FSK signal to generate a frequency scaled shift keying (FSSK) signal; and
transmitting the FSSK signal to the remote device, wherein transmitting the FSSK signal to the remote device comprises superimposing the FSSK signal as an alternating current signal on a power signal provided to the remote device via a wireline.
