Save the POPIT Label Sheets: The D8125 is
packaged with two sets of POPIT label sheets. One set
is marked “Bank 1” for use with the D7412GV2 and
D7212GV2. The other set is marked “Bank 2” for use
with the D9412GV2 and D9112. Use the sheets later to
label the POPITs. Refer to Section 9.3.6 POPIT Module
Point Assignments on page 40.

Wiring POPITs to the Data Expansion Loop
Use one two-wire data expansion loop or distribute the
POPITs on up to three loops. Setting DIP switches on
the POPIT Modules assigns them to point numbers.
Refer to Section 9.3.6 POPIT Module Point Assignments on
page 39.
