The input voltage range (DC-IN) is from 4.75V to 32V, with a typical operating voltage of 13.2V.
The power cable is provided as part of the FX Series package.
Caution:
Pins 1, 2, 3, 4, 5, 8, 9 and 10 are low voltage interfaces. It is strictly prohibited to connect these pins
to any power supply as there is a risk of damaging the FX Series.
5.1.1.1.
General Purpose Input/Output
The FX Series has two external GPIO ports, GPIO21 and GPIO25 (GPIO35 for FX100); as well as a
voltage reference line,
Vref
.
Vref
sets the reference voltage of the input or output of the two GPIOs. Leaving it unconnected sets
the GPIO level at 2.3V
– 2.6V by default. It is
strongly
recommended to connect to the required
GPIOs’ output voltage (2.8V ~ 15V).
Refer to the following table for the pin description of the GPIOs.
Table 8.

Voltage reference for the GPIOs
Note:
It is recommended to use a
6-wire cable accessory
for easy access to these three lines. Please
refer to section 13.1 Standard Accessories for more information about the 6-wire cable accessory.
When the voltage reference,
Vref
, is not connected, if one of the GPIO output is in High state while
the other is in Low state, the GPIO in high level voltage will be at 2.3V.To avoid this voltage drop, it
is recommended to use
Vref
to the desired output voltage.
