Confi guração do sensor DP-IAQ
A confi guração dos 2 dip-switch (DIP1, DIP2) permite o endereçamento, a modalidade de transmissão serial e a velocidade.
Por meio do DIP 1 é possível confi gurar o modo de operação da porta serial, selecionar a velocidade de transmissão e todos os
parâmetros necessários para o correto funcionamento do instrumento.

Se a função 8N1 (DIP1 SW5) for ativada, a função é desativada automaticamente a função Parity (DIP1 SW3) e a função Parity
check (DIP1 SW4),
Através do bit 6 do DIP 1 é possível ativar ou não a resistência de terminação de linha de 120ohm.
Tenha o cuidado de ativar esta resistência apenas no último instrumento da linha e não nos intermediários para garantir o cor-
reto funcionamento do sistema. O resistor de fi m de linha está ativo quando se seleciona Active.
A seguir encontra as confi gurações mais comuns para permitir a melhor operação com os sistemas Carel:
SW1 ON, SW2 ON, SW3 --, SW4 OFF, SW5 OFF, SW6 OFF.
Através do DIP 2 é possível confi gurar o endereço serial do instrumento, selecionando entre 1 e 247
