Tag Data/Control
The communication path between the IT2020 Reader Logic Card and the IT2611 RF
Module runs through the input/output (I/O) module that is connected to IP slot A. The
I/O module connects to the RF module through a ribbon cable terminating at a DB-25
connector mounted on the RF module interface bracket. The tag data/control cable
from the RF module connects to this DB-25 connector.
