The configuration of MDIS5 interfaces is possible through Device Manager of Windows OD, tab on the "MDIS5 devices" tab.
Types of interfaces can be identified by their name. Binary IO peripheral is a device called 16Z037_GPIO. The name of the configuration interface is 16Z034_GPIO. In Device Manager, you may find more devices of the same name. Therefore, you should display the properties to identified identify the particular interface. This interface should be placed in "cham-slot 2(is instance 2)" (see figure below). Next interface is HW watchdog, its name is XM01BC.
Each of these devices can be addressed via its unique identifier. The modification of identifier can be done in "Device Manager -> MDIS device -> Properties -> "Device Settings" tab.
