Note:

1. DI ports have two types: Dry or Wet.

2. For Dry ports

    0 means the external circuit is conductive.

    1 means the external circuit is NOT conductive.

3. For Wet ports

    0 means the voltage of input is between 10-30V

   1 means the voltage of input is between 0-3V

   3-10V is unstable status.

Set and Get DO Status

Take DO1 for example:

# #---- Set 0 to DO1 ----# #
# echo 0 > /dev/DO1

# #---- Set 1 to DO1 ----# #
# echo 1 > /dev/DO1

# #---- Get DO1 status ----# #
