4 Port Board ICL4P – Impinj E710 – Wi-Fi + PoE

A 4-port UHF RFID module for gates and multi-zone panels

The ICL4P is a UHF RFID reader on a bare board, made for system integrators and OEMs who build the reader into their own cabinet, gate or machine. Its four antenna ports can work together on one wide read zone, or separately on up to four nearby read points, all reporting from one board.

Two ways to use four ports

Performance and connectivity

Built on the Impinj E710, the ICL4P reads at up to 20 m and up to 1,000 times per second, which helps when a trolley or pallet of tagged items passes in one go. It runs Linux on an ARM9 processor designed for round-the-clock operation.

PoE support lets one Ethernet cable carry both power and data to the board, which is useful at a gate far from a power socket. Wi-Fi covers sites where cabling is not practical, and Bluetooth and 4G are optional. For commissioning, the board auto-scans over COM port or network; SDKs for all common languages handle the integration.

Planning the antennas

• Use the same type of coaxial cable on all four ports, and keep lengths similar so the ports perform evenly.
• Position antennas so neighbouring zones do not overlap, or one lane will pick up tags meant for the next.
• Decide which port serves which door or lane before installation, so your software can tell entry from exit.

Choosing between modules

For a single door or kiosk, the single-port ICL1P is the simpler and lower-cost board. If one controller must run more than four antennas, such as several toll lanes or a long conveyor, step up to the 8-port ICL8. The gate and portal reader guide explains common antenna layouts.
