Using GPIO and ReaderEnable

ThingMagic Vega Set Up Guide 11

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.

Table 3: GPIO connector pin out

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.
