Antenna Installation
The MP9320 V2.8 supports from one to four external antennas in a variety of
configurations. One- and two-antenna configurations are typical for most conveyor
and container tracking. Four-antenna configurations are used for portals and
loading dock doorways.

Warning
The SAMSys MP9320 V2.8 EPC UHF Reader is equipped with four (4) RF ports. To
prevent reader damage, active RF ports must be properly terminated with a 50 ohm load
or a functional UHF RFID antenna before power up. UHF Readers are factory configured
to operate on RF port 1. As a result, port 1 must be properly terminated before initially
powering on the reader. Before activating any additional RF ports, they must also be
properly terminated. Never power up the reader unless the appropriate loads or antennas
are connected. Always power down the reader before removing an antenna or load from
an RF port.
Activation of these RF ports is controlled by the internal MCW and MSW registers as
described in the MP9320 V2.8 User’s Guide, the MP9320 Field Installation Guide, and the
Comprehensive Heuristic Unified Messaging Protocol (CHUMP) Reference Guide.
