FCCMERA-3110-3L-4ML Overview
Networks on a machine or a vehicle-mounted rig take a beating that office-grade RJ45 latches were never designed for, and a loose camera or sensor cable usually shows up as an intermittent fault. The Arestech MERA-3110-3L-4ML answers that with four M12 Gigabit Ethernet ports alongside three RJ45 ports, making it the screw-locking networking option in the MERA-3100 series of fanless industrial PCs.
Compute comes from 9th or 8th Gen Intel Core i3, i5 or i7 desktop processors in the 35 W LGA1151 class, from the four-core i3-8100T to the eight-core i7-9700TE at up to 3.8 GHz, on an Intel Q370 chipset. Two DDR4 2400/2666 SO-DIMM sockets hold up to 64 GB, and Intel UHD Graphics 630 drives VGA and DVI-D at up to 1920 x 1200 plus a DisplayPort output at up to 4096 x 2160, so one MERA-3110-3L-4ML can drive three screens.
Networking is the reason to choose the MERA-3110-3L-4ML. GbE1 runs on an Intel i219-LM and GbE2 and GbE3 on Intel i210-AT controllers, all on RJ45 with Wake-on-LAN and PXE, while an Intel i350-AM4 module provides GbE4 to GbE7 on M12 connectors. Four removable 2.5″ SATA bays support RAID 0, 1, 5 and 10, and two CFast sockets, shared with mSATA, take a boot drive. Six RS-232/422/485 DB9 ports with auto flow control, 8x isolated DI and 8x isolated DO, six USB 3.2 and two USB 2.0 ports cover controllers and peripherals. The enclosure measures 241.5 x 92.6 x 230 mm and weighs 4.35 kg.
Power enters through a 3-pin terminal block at 9 to 48 V DC, with ignition sensing, a PC/car mode switch and protection against over-voltage up to 52 V, reverse voltage and over-current. With a 35 W processor the MERA-3110-3L-4ML runs fanless from -40 °C to 70 °C, and Arestech offers an external fan kit for 65 W processors at up to 60 °C. Vibration is rated at 5 Grms and shock at 50 G, and the fanless industrial PC wall or stand mounts. Where RJ45 is acceptable, the MERA-3110-7L keeps seven GbE ports on standard connectors, and the MERA-3110-3L drops to three.
