Help: Switchs with ascom driver for IPX800

I am looking for a user of the function relating to the use of switches in relation to the IPX800. I already use this function in another software, without problem, and here I can’t find how to make it work. I am using SGP PRO as a demonstration for 45 days, version 4.1.827, I have decided to use it definitively but I must be able to access the IPX switches, I have consulted the manual, but there is no nothing on how to make the setting and manage the use of swiths during a sequence. (For example, in my case, at the end of the sequence once the mount is parked, I have to disconnect it, and then cut the 12v power supply to it via its switch), thank you for the help you will give me, philippe
