1. A method for bi-directional digital communication between a device having a sensor for accumulating information and an external system, wherein a communication cable couples the device to the external system and wherein a microcontroller processes the accumulated information into processed information and communicates the processed information to the external system via a communication cable as a current signal, the method comprising the steps of:
communicating digital information from the device to the external system by setting, by the microcontroller, the output current less than an output low threshold for a logical 0 and higher than an output high threshold for a logical 1; and
communicating digital information from the external system to the device by the external device establishing a voltage less than an input low voltage threshold for a logical 0 and higher than an input high voltage threshold for a logical 1.
