A wireless diagnostic sensor link for providing wireless communication between a signal source and a monitoring device. The wireless diagnostic sensor link includes a signal input device operable for receiving a signal from the signal source in a first communication protocol in the form of an analog signal, converting the analog signal to a digital signal, and transmitting the digital signal in the form of a wireless communication protocol. The wireless diagnostic sensor link also includes a signal output device, which receives the digital signal. The signal output device is in electrical communication with the monitoring device, and is also operable for communicating with the signal input device. The signal output device converts the digital signal back to an analog signal, and sends the signal to the monitoring device in the form of a second communications protocol.
