Axiomtek AX92320-2GbE 4 Port M12 10GbE PoE+ Intel X710-AT2 PCIe Frame Grabber

A vision cell with two GigE cameras needs data and power on each cable, without extra injectors or a separate switch in the cabinet. The AX92320-2GbE is the two-port build in the Axiomtek AX92320 series, a PoE card that Axiomtek describes as a GigE frame grabber card for machine vision and surveillance applications. It fits the PCI Express slot of a multi-channel vision control system, and we specify it for the systems we build and supply.

The card carries two independent Gigabit PoE ports on 8-pin RJ45 connectors. Each port has its own Intel i210-AT controller running at 10/100/1000 Mbps, with support for 9.5KB jumbo frames and IEEE 1588. The host interface is PCI Express x4, so both ports run at full Gigabit rate side by side. Because each camera sits on a dedicated controller, one busy stream does not hold up the other.

Each port is IEEE 802.3at compliant and delivers up to 30 W at 54 V DC. From the PCIe slot alone the card supplies up to 20 W of PoE in total; connect the 6-pin ATX power connector and the total rises to 120 W. PoE power management software and smart on/off for each LAN port help when a camera needs a remote restart. For four cameras, the AX92320-4GbE doubles the port count on the same board. Our guide to PoE power budgeting for multi-camera systems covers how to size the supply.

The ATX connector takes 12 V DC or 24 V DC, drawing 12 A at 12 V or 6 A at 24 V, and the PoE output has overload protection. The card operates from 0 to +60 °C with air flow and stores from -20 to +80 °C. It measures 168 x 111 mm, and Axiomtek lists Windows 7 and 10 (32/64-bit) support.
