Note that addresses in the Connection Properties window are

so that a check mark appears in the box.

The Connection Name by default is Discrete 16 Bit Exclusive
Owner. This is the 16-bit rack connection we want. The first
available I/O addresses are I:3.1 and O:3.1, where the
1747-SCNR scanner is in slot 3 of the processor chassis. The first
available starting I/O addresses have been placed into the Input
Address and Output Address fields, because automatic
addressing was previously selected in the Auto Address
Preference screen.
