DFI EC700-AL-E3940-4LAN Intel Atom x5-E3940 Low-Profile Embedded PC with 4x GbE and Extended Temperature

Small network appliances, from protocol gateways to firewall boxes, often need four Ethernet ports more than they need raw speed. The EC700-AL-E3940-4LAN is the four-LAN Atom x5-E3940 build of the DFI EC700-AL series: a low-profile fanless embedded PC with four GbE ports, four COM ports and an extended temperature rating.

The Atom x5-E3940 runs four Apollo Lake cores, which suits routing, protocol conversion and data logging. Memory fits one 204-pin DDR3L SO-DIMM, up to 8 GB in total. Intel HD Graphics drives two displays, and the EC700-AL-E3940-4LAN runs Windows 10 IoT or Linux, as DFI states for Apollo Lake.

Networking is four Intel I210 GbE ports on RJ45, with two USB 3.0 Type-A ports, four RS-232/422/485 ports on DB9 and one DisplayPort output at up to 4096×2160 at 60 Hz and one VGA at up to 1920×1200. Storage is a 2.5-inch SATA bay and a full-size mSATA slot. A full-size Mini PCIe slot with nano-SIM takes an optional 4G module, and an M.2 2230 E key slot takes optional Wi-Fi, with antenna holes on the front panel.

Power is 9 to 36 V DC on a DC jack. DFI rates the EC700-AL-E3940-4LAN from -40 °C to 70 °C and lists CE, FCC Class A, RoHS, CCC, UL and KC compliance, and it mounts on a wall, a VESA plate or a DIN rail with optional kits. We supply it configured and tested, with memory, storage, the OS image and any 4G or Wi-Fi modules fitted before it ships. The EC700-AL-E3940-2LAN swaps two GbE ports for two more USB ports, and the EC700-AL-E3940-4LAN-2DP adds a second DisplayPort, 4 GB onboard and 32 GB eMMC.
