You can get the return code from get_MDI_status(CARD0, 9) and
get_MDI_status(CARD0, 10) to read input status. If you don't set
the mode to 1, you still can read the MDI status by this function.

General Purpose IO
General purpose I/Os are input and output signals that user can
freely use. For example: encode counters, isolated DIO…etc. In
this section, all general purposed I/Os and their function calls are
discussed.
4.6.1
Encoder Counter
In this section, the following functions are discussed.
set_cnt_iptmode(CardID, EncNo, IptMode)
set_cnt_to_axis(CardID, EncNo, Axis, Resolution)
set_cnt_value(CardID, EncNo, Value)
get_cnt_value(CardID, EncNo, *Value)
Each PCI-8372+/8366+ has 3 encoder counters and can be use to
receive A/B phase signals from a linear encoder. Also these
counters can be programmed to receive CW/CCW, OUT/DIR type
signals.
Input circuit
The input circuits for EA, EB and EZ signals are shown below
Figure 4-30: Pulse Input (Encoder Counter) Circuit
Note
:
The voltage across each differential pair of encoder input
signals (EA+, EA-), (EB+, EB-) and (EZ+, EZ-) should be at
least 3.5V or higher. Therefore, the output current must be
observed when connecting to the encoder feedback or motor
driver feedback as not to over drive the source.
