Identix Catena installation diagram

Installation diagram

Identix Catena is a low-cost solution that expands the antenna deployment capacity for the Identix UHF RFID readers and gateways.

With the Identix Catena you can connect up to 32 RFID antennas using a 4 port Identix UHF RFID reader, which offers an ideal solution for applications requiring the deployment of multiple antennas, like large read zones, RFID enabled shelves and intelligent cabinets or freezers.

The Identix Catena is simple to install and control. Simply connect an RF coaxial cable from the antenna port on an Identix UHF RFID reader to the Catena port and the Catena is immediately recognized and controlled by the reader’s firmware.

The individual RF coaxial cable serves to power and control the Catena, thus eliminating the need for separate dedicated cables for power and antenna switching. This architecture frees the GPIO port for other uses.
