2.3 INSTALLING THE UHF-CNTL-485-02
The UHF-CNTL-485-02 RFID Controller supports RS485 communications and Escort
Memory Systems’
Subnet16™
multi-drop bus architecture and RFID network
protocol.
Through the Subnet16 protocol, up to 16 UHF-CNTL-485-02 units can be connected
to one Subnet16 Gateway and four UHF-CNTL-485-02 units can be connected to
one Hub interface module. Subnet16 Gateways and Hubs assign each attached
controller a unique Node ID number through which communication with a host
computer and/or Programmable Logic Controller (PLC) is achieved.
For applications that require multiple UHF-CNTL-485-02 controllers, install and
configure each device one at a time.
