4.1 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-5004
series hardware (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 conductive.

A port that is configured as an output can also be read back!
4.1.1 Digital Input/Output
For input/output of individual digital values the single operation
mode is used. The subdevices are defined as follows: subdevice 0 is
always of type ME_TYPE_DI and subdevice 1 of type ME_TYPE_DO.
The sub-type is always ME-SUBTYPE_SINGLE.
