Single Operation Mode
Individual values can be read or written in this operating mode.
Notes:
The digital-I/O channels direction is determined by the ME-582x hard-
ware (opto-couplers).
In power-down state and after switching on the PC all outputs are in a
high-
impedance state. Only if “1” is written, the output changes to con-
ductive.
A port that is configured as an output can also be read back!
