  • Application

    The Marlin is designed to provide a low-cost, rugged computer for well/deep drilling applications where the computer needs to be up to 100 meters away or longer with additional In-Line repeaters. The Marlin interconnect is designed so that the I/O subsystems that are connected to its ultra-high-speed I/O may operate in a remote location while collecting images and other data and then send it all up to the base station via the Gigabit Ethernet port, which also powers the entire system and I/O devices.  The Atom’s astounding performance is ideal for remote control of I/O functions in defense and UAV applications, as well as commercial and industrial applications. The Marlin is widely deployed in oil/gas exploration and unmanned robots for hazardous applications in which the computer is exposed to the harshest possible environments and where power, weight, and size are the main considerations. The Marlin may be ordered with PoE or optional solar power supply for commercial and industrial applications in which the computer system is placed out in the field where there is no power available. The S502-LP is fully compliant to MIL-STD 810F, MIL-S-901D, DO-160D and IP67 (MIL-STD 1275 Optional via PCM).
  • General Description

    The S502-LP "Marlin" is a fully-sealed, rugged, ultra-low-power, lightweight, Intel® Quad Core Atom™-based computer system. It is designed to provide the lowest power consumption possible in a fully ruggedized conduction cooled module, operating up to -40°C to +85°C (-20°C to +75°C Standard). The Marlin is targeted for applications where an ultra-low-power, fully sealed, submersible rugged computer is needed to operate up to 100 meters away from the base station utilizing Power over Ethernet (PoE) (IEEE 802.3AT type 2) technology with ultra-fast I/O and processing capabilities.  The Marlin provides the best possible performance per dollar and per watt, utilizing hi-density rugged interconnects to provide easy interconnect to system I/O and user I/O. 
    The Marlin utilizes the Intel® Quad Core Atom™ processor with 2MB of L2 cache operating at 1.91 GHz and deep sleep capabilities for ultra-low power consumption when not active. To harvest this incredible CPU performance, the CPU is coupled with up to 8GB of 1333MHz DDR3 RAM with Error Correcting Code (ECC).  The entire Marlin system consumes less than 15W in normal operation. This makes the Marlin the highest performance per watt system in a fully rugged, sealed enclosure on the market.
    The I/O subsystem for the Marlin is designed to support a wide array of standard and custom I/O functions. The S502-LP supports one Gigabit Ethernet port with Power over Ethernet (PoE) per IEEE 802.3AT type 2. This version of PoE supports up to 25W, which may be used to power the entire system as well as the external I/O connected to the USB ports. Additionally, the Marlin supports one USB 3.0 and three USB 2.0 ports, up to 1TB of fixed SSD storage, five optically isolated digital General Purpose I/O lines, one VGA port, one COM port with RS-232/422/485 options and isolated I2c bus for additional low cost sensors and I/O. Additional I/O functions such as dual Gigabit Ethernet, CANbus, ProfiBus, Wi-Fi/Bluetooth, GPS, and many other I/O functions are provided via one SAM™ Site with I/O via the J2 connector. 
  • Technology Used

    The S502-LP utilizes the most efficient Quad Core Atom™ processor from Intel®. The BayTrail CPU is a third-generation Atom™ processor with a fully integrated memory controller for the best memory performance possible. This CPU is considered to have the best performance per watt in the market. Due to the embedded Intel® HD Graphics, the graphics engine of the BayTrail has the best performance of any Atom™-based integrated video in the market with outstanding performance in 2D and 3D with DirectX™ 11 and OpenGLES 3.0 support.
  • Cooling

    The Marlin is equipped with GMS's patent pending RuggedCool™ technology, which is the most unique conduction cooling system in the industry, and is the only system that operates up to -40°C to +85°C at full load without throttling the CPU! This cooling approach provides the lowest thermal resistance to the case while providing the highest shock specifications known in the industry. The S502-LP is a stand-alone, fan-less system and should be mounted directly to a metal surface that provides a reliable conductive thermal path for dependable operation.
