1. A probe for optical communication with a device external to the probe, the probe comprising:
- an optical receiver for receiving a light signal from an external device and generating a corresponding data signal; and
a voltage converter for converting a first voltage signal from a diagnostic tool coupled to the optical receiver to a second voltage signal, the second voltage signal being coupled to the optical receiver to operate the optical receiver in a high speed mode.

Abstract
An optical communication probe enables a diagnostic tool to optically communicate with an external device, such as an appliance, through a low intensity indicator light of the external device. The communication probe includes an optical transmitter, an optical receiver, and a voltage converter for converting a first voltage signal received from the diagnostic tool to a second voltage signal. The second voltage signal is coupled to the optical receiver to operate the optical receiver in a high speed mode.
