In case of input through RX1, RX2 or RX3, jumpers JP5 (RX1), JP6 (RX2) or JP7 (RX3) control digital input
channels (RX1, RX2 or RX3) from PORT3.
About only input channels, set some of jumpers JP5 (RX1), JP6 (RX2) or JP7 (RX3) to OPT.
About no-input channels, set other of jumpers JP5 (RX1), JP6 (RX2) or JP7 (RX3) to GND.
