Vecow VIG-120M NXP i.MX 6UL Cortex-A7 IoT Gateway with M12 LAN, Dual CAN Bus, Four COM Ports and Wide Temperature

Machines and fleet equipment that use a CAN bus are usually the same ones that shake connectors loose. The Vecow VIG-120M is the M12 full-I/O build of the VIG-100 series, a fanless IoT gateway on the NXP i.MX 6UL with two CAN bus ports, four RS-232/422/485 ports, eight GPIO lines and M12 LAN.

The NXP i.MX 6UL is a single Arm Cortex-A7 core with 512 MB of DDR3L, a low-power choice for protocol conversion and data forwarding rather than heavy local processing. The VIG-120M ships with Debian Stretch R01 on Linux kernel 4.9, stores the OS on 512 MB of NAND flash, and takes micro SD cards up to 128 GB, with eMMC up to 32 GB as an option from Vecow.

I/O covers two 10/100 Ethernet ports on screw-locking M12 connectors, which hold up better than RJ45 under vibration, one USB 2.0 Type A port with OTG support and four software-configurable RS-232/422/485 ports with 8 kV ESD protection, two on RJ45 and two on DB9, plus eight 3.3 V TTL GPIO lines on a 10-pin terminal block. Two CAN 2.0 A/B ports sit on a six-pin terminal block. A full-size mini PCIe socket with an external SIM slot takes an optional 4G LTE and GPS module or Wi-Fi module, with four antenna positions, and eight user-programmable LEDs show status.

Power is 6 to 40 V DC on a three-pin terminal block, and the VIG-120M runs fanless from -25 °C to 70 °C, with shock tested to IEC 60068-2-27 at 50 G and vibration to IEC 60068-2-64 at 5 Grms. The EMC list covers CE and FCC, and the gateway is designed to EN 50155 and EN 50121-3-2 requirements. It wall-mounts on a bracket or fits an optional DIN rail kit. The VIG-120 uses RJ45 LAN instead, and the VIG-110M drops the CAN bus.
