GAO RFID provides a selection of Digital I/O adapters design to work in conjunction with RFID Reader Antenna Hubs and the UHF Gen 2 RFID Reader/Writers. These digital adapters have protocols design to create a larger read zone and attach multiple antennas to one reader. Additionally, most of these devices are compliant with the Restriction of Hazardous Substances (RoHS) directive, the European Conformity (CE) directive, and the Federal Communications Commission (FCC) certification. Furthermore, several of these antennas enable from 5 to 32 antennas to be attached to a single reader in order to provide a low cost, large, contiguous RFID read zone. The digital I/O adapters have communication ports that provide excellent communications capabilities; some of them offer an isolated RS232C/RS485 combination port, a non-isolated RS232C port and an RJ-45 port for 10/100 Mbps EtherNet/IP peer-to-peer messaging. Other key technical feature of these adapters include an operating temperature that ranges from -40 °C to 80 °C (-40 °F to 176°F), which can vary depending on the specific features of the device. The digital I/O adapters have IP52 protection standards by which they are protected from limited dust ingress and are protected from water spray less than 15 degrees from vertical.

GAO RFID offers digital input/output adapters in different form factors and materials. These adapters are built with durable, resistant materials and come in convenient colors such as black and white to fit into the décor of any environment. Also, the digital adapters have an easy installation with feedback for reliable installation.

The digital I/O adapters are designed to enhance performance, increase read zone size, add more antennas to the user’s readers, and enable use with antenna hubs and RFID readers. These devices have several applications such as RFID smart shelves or document tracking applications. Moreover, this type of network gives the advantages of central control and easily overview of event log reports.
