Function Terminal Name Input/Output
In this unit, the terminal with asterisk mark (*) is (open) terminal which is not connected to the outside.
Controlled with serial data command
from micro computer.
When not used, set it as the input terminal and
open it by connecting to 0V, or set it as the output
terminal and open it.
