The LEC-7920 is a fanless embedded system designed for embedded and industrial computing applications, featuring Intel i5/i7 and Celeron processors. Its robust design, including an aluminum extrusion enclosure, aids in heat dissipation, allowing it to sustain operating temperatures from 14-131°F (-20-55°C). The system is equipped with dual LAN, DVI-I, and DVI-D connectors, catering to high-demand internet and video playback applications.
The LEC-7920 offers a comprehensive set of features for various industrial applications. Its dual DVI-I and DVI-D video outputs, powered by the Intel HD Graphics Engine and Chrontel's CH7318 SDVO to DVI converter, support resolutions up to 1920x1080 @ 60 Hz for both analog and flat panels. The dual 10/100/1000 Mbps LAN ports, driven by Intel 82574L Ethernet controllers, support advanced management features such as IPMI pass-through via SMBus or NC-SI, WOL (Wake-on-LAN), remote wake-up, PXE function, ISCSI boot, and VLAN filtering.
For connectivity, the system provides six USB 2.0 ports (four external Type A and two internal headers), two RS232 serial ports with hardware auto-flow control, and a digital I/O port (DB9 female) offering four digital inputs and four digital outputs (5V TTL level, max 50mA per port). Audio input and output are available via Mic-in and Line-out jacks.
A unique feature is the power-on switch accessible through a Phoenix connector, enabling distant control of the system. The system also includes a SIM card reader for 3G module installation, supporting wireless communication. Storage options include a 2.5" HDD/SSD drive bay and a SATA-DOM connector, both supporting SATA II with data transfer rates up to 3.0 Gb/s.
The LEC-7920 is designed for ease of maintenance and hardware setup. The user manual provides detailed instructions for installing critical components such as system memory (DDR3 SO-DIMM up to 8GB), CPU (Intel i5, i7, Celeron P4500 on micro-PGA 989 socket), wireless modules (Mini-PCIe slot), 3G SIM cards, and hard disks. The CPU installation involves aligning the CPU's triangle with the socket's triangle and securing it with a knob. For the SIM card, a slide-out reader mechanism allows for easy insertion and secure locking.
The system's fanless design, coupled with its aluminum extrusion enclosure, minimizes maintenance requirements related to cooling. The integrated Fintek F81865 Watchdog Timer (1-255 level) provides a critical maintenance feature by automatically detecting system anomalies and resetting the processor, ensuring system stability and reliability in industrial environments. The manual includes instructions for programming and verifying the watchdog timer and digital I/O control via the GPIO port, using the LannerIO driver and sample programs.
Physical installation is also straightforward, with a wall-mounting kit provided. The process involves making holes for anchors, pressing anchors flush with the surface, screwing in threaded screws, and attaching the wall mounting bracket to the device.
The manual also outlines warranty and RMA service procedures, emphasizing the importance of proper packing for defective units to prevent shipping damage. This comprehensive approach to design, installation, and maintenance ensures the LEC-7920 is a reliable and manageable solution for embedded and industrial computing needs.
