Sink (NPN) / Source (PNP) radio button
Select Sink (NPN) / Source (PNP) MODE.
Set button
DIO conguration must be dened before DO output condition.
Get button
Dene DIO conguration to get DI input condition.
Output data (Hex)
DO output condition is dened by a hexadecimal bitmask - on / off.
Range: 0x00~0xFF, 1: High; 0: Low.
Input data (Hex)
DI input condition is dened by a hexadecimal bitmask - on / off.
Range: 0x00~0xFF, 1: High; 0: Low.
Example
Dene Output data 0x00 LED all bright on sink(NPN) mode.
Dene Output data 0xFF LED all bright on source(PNP) mode.
Loopback test (connect pin.1-11 ~ pin.10-20):
Dene sink(NPN) mode output and Get source(PNP) mode input.
