+To use 1-Wire on a Unipi unit with OpenSource OS, you must install and configure OWFS. In the case of an OS with EVOK, OWFS is already installed.
+**Do not install OWFS for Mervis OS**! It uses an alternative method to work with 1-Wire and collisions could occur.

+**DO** status reading:
+<code>cat /run/unipi/io_group1/do_1_01/do_value</code>

-SysFS driver included in the kernel module provides easy file-based access to all IOs. Check the following examples to get started:
+**DI** status reading:
+<code>cat /run/unipi/io_group1/di_1_01/di_value</code>
-Set state of DO to 1
+Status reading of all first section **DI**'s:
-<code>echo 1 > /sys/devices/platform/unipi_plc/io_group1/do_1_01/do_value</code>
+<code>cat /run/unipi/io_group1/di_[1-3]_[0-9][0-9]/di_value</code>
-Read the state of DI
+Status reading of all available **DI** units:
-<code>cat /sys/devices/platform/unipi_plc/io_group1/di_1_01/di_value</code>
+<code>cat /run/unipi/io_group[1-3]/di_[1-3]_[0-9][0-9]/di_value</code>
-All IOs can be accessed similarly.
