Using GPIO and ReaderEnable
Two general purpose inputs, one general purpose output and the ReaderEnable input are
provided through a 6 position Tyco Amp 1445049-6 Connector (Mating Shell: 1445022-6,
Mating Contact: 794610-3). GPIO describes the pin out for this connector.
GPIO
The GPIO signals can be accessed using the Config tab on Reader Assistant as
described in the previous section.

GPIO Logic Voltage Levels
The following are the voltage levels between Ground (Green) and the input or output pin
for logic high and low:
Inputs
 Low - apply a signal between 0 and 0.8 V
 High - apply a signal between 2 and 5 V
Outputs
 Low - outputs a maximum 0.4 V and will sink 12mA
 High - outputs a minimum of 2.4 V and will source 12mA.
