evidence: The ECI states that an EVM consists of two units, control unit and balloting Unit, with a five metre-long cable connecting the two units. A balloting unit caters to up to 16 candidates. EVMs come in many different variants. They have evolved over time and become more robust. In the case of pre-2006 model (M1) and the post-2006 model (M2) of EVMs, four balloting units can be cascaded together to accommodate up to a maximum of 64 candidates (including the option of none-of-the-above or NOTA) and used as a single unit.
