Io-7. Sync-Off, Not-Invert - ITech IT-M3900D Series User Manual

5.11.7 IO–7. Sync-Off, Not-Invert
IO-7 pin can be set to 【Sync-Off】, 【Input】, 【Output】.
Parameter Description
IO–7. Sync-Off,
Not-Invert
How to Use
When pin 7 is set to default Sync-Off function, pin 7 has bi-directional I/O func-
tion, which can receive pulse signal input from the external instrument and also
can output pulse signal to external instrument. The parameter requirements of
this pulse signal are as follows:

This default function means that pin 7
performs bi-directional and synchronous
control over the turn-off of [On/Off].
Pin 7 receives the level signal from the
outside.
Pin 7 sends the digital signal (1, 0,
PWM) to the outside.
True By default (Not-Invert), the out-
put digital signal is 1 (i.e. low
level), and in the case of
Invert, the output is high level.
False By default (Not-Invert), the out-
put digital signal is 0 (i.e. high
level), and in the case of
Invert, the output is low level.
PWM Digital signal of PWM.
