Thank you and sorry,

I had searched by putting the name of the record and nothing appeared with direct relationship.

Thank you

Very simple.

1. Read the datasheet - this is always going to be your first step.

2. Find out where the uid is located, as their location is family specific.

3. Fix a data type of your choice to that address.

4. Done.
