Warning
The SAMSys MP9320 UHF Reader is equipped with four (4) RF
ports. To prevent reader damage, 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 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 User’s Guide,
the MP9320 Field Installation Guide, and the Comprehensive
Heuristic Unified Messaging Protocol (CHUMP) Reference
Guide.
