It consists of 6 circuits which convert signals from Vcc logic levels to Vdd logic levels.

Suppose we need to convert the voltage level of data pins D0-D3 which is of 3.3 V (parallel port) to 6V level. It means we have to convert the HIGH of 3.3 V to HIGH of 6V. So we apply 3.3 V to Vcc from the status pin of parallel port and 6V to Vdd. For this we connect the data signals D0-D3 as below and get the output of +6V.

Atualmente, o software de controle remoto é usado principalmente na área de escritório, com funções básicas como transferência remota de arquivos e modificação de documentos.
