Taking pin 3 as an example, IO-3 contains three function options, the first option
Off Status is the default function, and this function is also a special custom
function unique to this pin (the seven pins each have a different custom function).
The second and third options (Input and Output) are the general digital I/O
function, and the parameter settings and functions of the seven pins are the
same.

System-Related Functions
PS Clear: This default function means that
when the instrument generates protection,
the protection state can be cleared via this
pin.
Input: Pin 1 receives the level signal from
the outside.
Output: Pin 1 sends the digital signal (1, 0)
to the outside.
PWM: Pin 1 sends the PWM signal to the
outside.
PS: This default function means the output
level from pin 2, which displays that
whether the instrument is under protection
or not.
Input: Pin 2 receives the level signal from
the outside.
Output: Pin 2 sends the digital signal (1, 0)
to the outside.
PWM: Pin 2 sends the PWM signal to the
outside.
CH1: Apply the configuration to Ch1.
CH2: Apply the configuration to Ch2.
CH1&CH2: Apply the configuration to Ch1
and Ch2.
Off Status: This default function indicates
the existing [On/Off] state of the
instrument.
Input: Pin 3 receives the level signal from
the outside.
Output: Pin 3 sends the digital signal (1, 0)
to the outside.
CH1: Apply the configuration to Ch1.
CH2: Apply the configuration to Ch2.
