The Decabit code consists of 10 characters of "+" and "-" that directly translate to numbers from 0 to 126. These values are mapped to the corresponding ASCII characters/numbers. This tool will accept both ASCII characters or their numerical code (example: A or 65) and can output the same when decoding.

The Decabit code is a series of electrical pulses intended to encode data via power lines (alternative current). It is a modulation of the electrical ripple similar to the CPL (current carriers in line), mainly used in Europe, for example for the transmission of meter readings.
