The Quattro (Model R4321P) is a compact long range RAIN RFID reader of the easy2read© product line, well suited for retail and warehousing installations.

The Quattro reader has 4 antenna ports capable of a 31.5 dBm maximum power enabling to build RAIN RFID portals for long range reading. Its slim form factor makes it easy to install even when limited space is available. It offers the Ethernet (PoE) and USB communication interface in order to simplify the installation both on large and single read point solutions. The Power over Ethernet capability permits to provide power and to communicate with the reader with a single cable.

The USB host port, combined with the internal computing architecture, permits to connect USB peripherals like barcode scanners, keyboards, printers and many others transforming the Quattro reader in a powerful and versatile identification platform.

The Quattro is based upon an embedded Linux platform and it’s easily configurable using an internal web interface. System integrators can customize the behavior of the reader installing Java code that, having access to all the RFID features and interfaces, permits a full customization.

The Quattro reader complies with and can operate in both European and US regulatory environments and, due to its multiregional capabilities, it’s ideal for integration in devices requiring compliance to different geographical regions.
