AirLink FXT Series User Guide-REv002[1].pdf

Table 8 page 36
Pin 1 GPIO25 General purpose input/output
Pin 2 GPIO21 General purpose input/output
Pin 3 Vref Voltage reference for the GPIOs

Table 9 page 37
Pin 1 GPIO21 I/O Vref General purpose input/output
Pin 2 GPIO25 I/O Vref General purpose input/output
Pin 3 Vref I 2.6V ~ 15V Voltage reference for the GPIOs

So which is it?

Experimentation seems to show Pin 2 (orange lead) is GPIO21
Pin 1 (Brown lead) is GPIO25

Hi
The first column in table 8 refers to the pin number wheresas,table 9 providing further description of the pins has the first column just refering to the general serial number and not pin number.
