Product Description

 

Lantronix G520 cellular gateways target industrial communication, cybersecurity, and transportation

 

Lantronix G520-series 4G LTE Cat 4 and 5G cellular gateways are designed to address challenges in Industry 4.0, security, and transportation markets with three/four separate gateways all based on an unnamed ARM926EJ-S-based CPU running at 600 MHz that's most likely Microchip SAM9X60 processor introduced in 2020.

All gateways are from the same base with variation for specific markets:

• G526 Industrial Gateway with LTE Cat 4 Ethernet, Serial, I/O, Fieldbus conversion, and other industrial protocols

• G527/G528 Security Gateway with LTE Cat 13 or 5G, built-in cryptographic secure element and PSE-PoE

 

Lantronix G520-series specifications:

• SoC - ARM926EJ-S-based processor running at 600 MHz with 32 KB instruction cache and 32KB data cache

• System Memory - 256MB DDR2 SDRAM

• Storage - 8MB SPI flash for OS, 256MB parallel NAND flash, MicroSD slot, or USB flash drive for user data storage

• Connectivity
  • Cellular options

    • LTE Cat. 4 with 3G and, depending on the regional variant, 2G fall-back modes on industrial pack

    • LTE Cat 13 (uplink) / 7 (downlink) with 3G fall-back mode on security pack

    • 5G, Sub-6 GHz with both LTE Cat. 13 (uplink) / Cat. 20 (downlink) and 3G fall-back modes

    • Dual SIM / Single standby via two mechanically secure mini-SIM holders OR MFF2 SIM(s) combination of (i) 'MFF2 + mini'; or (ii) 'mini + MFF2'; or (iii) 'MFF2 + MFF2' SIMs, substituted for the standard two mini-SIM trays.

  • Wi-Fi & Bluetooth

    • 2T2R Wi-Fi 5 via an RP-SMA antenna connector

    • Bluetooth 5.1 via Wi-Fi's rightmost RP-SMA antenna connector

    • Optional 2T2R WiFi6/6E

  • Dual 10/100M Ethernet with 1x LAN RJ45 port and 1x WAN RJ45 port user-reconfigurable as second LAN port

  • GNSS

    • Qualcomm IZat location services, Gen. 8c/9c or u-blox M8 (transport pack)

    • Concurrent GPS and GLONASS (security gateway 5G model)

• USB - 1x USB Type-A host port

• Serial

  • RS-232 full via DB9 connector

  • RS-485 via 5-pin COMBICON header

• I/Os

  • 2x IOs with common ground via a 3-pin COMBICON header and a tool-less plug configurable as analog input or digital output

  • Input: 0V ~ 2.5V DC (Zero); 3V to 50V DC (One)

  • Output: open collector; 200 mA max.; 50V DC max.

• Sensor - 3-axis accelerometer (STMicroelectronics LIS331DLH)

• HW Security - Microchip ATECC608 secure element on security variant

• Misc

  • 9x LEDs for power, connectivity, some user-programmable

  • RTC with 100-day data retention period, approximately 15 mWh lithium manganese battery (not functional below -20°C)

• Power Supply

  • Input voltage - 10.8 to 60V DC via 3-pin Nano-Fit header

  • PSE-PoE+ for Security pack only (30W per LAN port)

  • "Last Gasp" with about 100 seconds of power via 2 96 mWh Li-ion batteries (not functional below -10°C)

  • Digital Input (Ignition) on the third pin of the 3-pin header

• Dimensions - 131.5 x 81.27 x 25 mm without connectors (Brushed aluminum alloy enclosure)

• Weight - About 300 grams

• Temperature & Humidity

  • Operating: -30°C tp +70°C; up to 95% RH

  • Storage: -40°C to +85 °C; up to 95% RH

 

Each gateway comes pre-configured with Lantronix's ConsoleFlow cloud-based device management and comes with a web-based user interface to configure networking (WiFi, Ethernet, Cellular, VPN, routing…), security (firewall, VLAN, SIM pin, etc..) , and industrial communication protocols that include EtherCAT, DLMS client, DNP3 Outstation, Modbus master, IEC104 slave, and IEC 101 master.

While not specified in the description, Lantronix G520-series cellular IoT gateways clearly run OpenWrt as the company offers a G520 SDK to create custom packages and build custom firmware images, and the documentation assumes that "you have a computer running a supported Linux distribution (or VM) and are familiar with the OpenWrt build system and the Lantronix Web Admin for configuring G520 series devices."
