Acoustic node for configuring remote device

An acoustic node coupled to an industrial process device within a sealed housing, comprising:

• a microphone coupled to a receiver and configured to receive one or more incoming tones from a remote programming device external to the housing;
• a speaker coupled to a transmitter and configured to transmit one or more outgoing tones to the remote programming device;
• an audio processor;
• and
• a memory device storing processor-executable instructions that, when executed by the audio processor, configure the audio processor for:
• establishing communication between the remote programming device and the industrial process device based on the received one or more incoming tones;
• converting the received audio signal to incoming digital data;
• authenticating the remote programming device based on the incoming digital data;
• and
• determining a command based on the incoming digital data and instructing the industrial process device to execute the command,
• wherein the remote programming device transmits configuration information corresponding to the command to the industrial process device.
