9.4 Output Configurations
When an I/O port is configured as an output, the V
IN
signal must be connected to a supply to pull
up the I/O port when it is not activated. Setting the I/O port pulls down its output to the GND. V
OUT
supply may be used to supply V
IN
signal and the external load. The following examples show how
to connect a load ( a relay, a light, etc.) to the L-L100 Reader using the internal supply (V
OUT
) or an
external supply.
