Invert
How to Use
When pin 6 is set to default Sync-On function, pin 6 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:

forms bi-directional and synchronous con-
trol over the turn-on of [On/Off].
Pin 6 receives the level signal from the
outside.
Pin 6 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 lev-
el), 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 lev-
el), and in the case of Invert, the
output is low level.
