Model E4-DAS, takes its name from being an Easy to utilize, Ethernet enabled, Embedded and Environmentally adaptable PC/104-based Data Acquisition System. The latest line of systems from ACCES, the E4-DAS is designed for rugged embedded applications requiring superior performance and a high degree of protection from damaging vibration and shock environments commonly encountered in military and defense, avionics, communications, process control, automation and other real-world applications. The completely integrated E4-DAS is packaged in a lightweight aluminum enclosure with a railed card-cage subassembly for easy serviceability. Internal elastomer inserts are also provided for vibration and shock mitigation. The systemís fanless design is fully conduction cooled, enabling the box itself to dissipate the heat by heat-sinking the CPU and power supply on each end of the stack. The E4-DAS can accommodate stacks of two to six PC/104 boards (including the CPU and power supply), allowing the unit to incorporate a
wide range of analog and digital I/O, serial communications, relay and TTL output, wireless, Ethernet and other functions. An internal single (+5 V), or optional triple (+5, Ī12 V) output DC/DC power supply is used to accept system power sources of 12, 24, or 48 V. I/O is accessed via connector cutouts on the unitís end plates.
The standard system configuration utilizes a Intel Atom processor (speed can vary) and integrates all the standard functions of a PC. Memory up to 2GB DDR DRAM in SODIMM socket with a variety of SSD or SATA devices available for operating system/storage. All CPUs used come with USB 2.0 ports (multiple), LAN, as well as on board VGA/LVDS or optional HDMI interface allowing connections to a CRT and a wide variety of Display interfaces.
Standard Configuration 1A
Built upon our standard configuration using a 1.8GHz Intel Dual core Atom D525. This system adds up to 6 channels of 16-bit LVDT/RVDT signal conditioning, 16 analog inputs and 8 analog outputs with 12-bit, 100KHz conversions, 48 digital I/O lines, 8 opto-isolated digital inputs (AC or DC) with change-of-state interrupt generation and 8 electro-mechanical relays. Standard PC functions include 1GB LAN, USB keyboard and mouse, four USB and two RS-232 ports.
Existing Configuration 2
Configuration 2 utilizes a 0.6GHz to 1.8GHz Intel Pentium M / Celeron-M processor. The Intel Graphic controller "Extreme Graphics 2" is integrated into the chipset and can drive either a CRT or LVDS LCD. The system includes 128-1024MB DDR-DRAM which can be added via a SODIMM200 socket. Power management incorporates ACPI/APM functions which utilizes Intels Advanced SpeedStep (Pentium only) feature. This feature-rich system also incorporates PCI 2.2 Bus, EIDE, 4 x USB2.0, 2 x RS-232 COM ports, PS/2 keyboard and mouse, parallel printer, AC97 sound, 10/100MBit LAN and more.
Existing Configuration 3
onfiguration 3 uses a Intel Atom N2000 at 1.6GHz, SO-DIMM socket for up to 2GB DDR3, 2 SATA ports w/RAID for a wide variety of storage options, optional mPCIe socket, VGA, 4 USB 2.0, 2 RS-232 serial ports, 2 1GB LAN ports and more.
Existing Configuration 4
Configuration 4 uses a Intel Atom E3800 at 1.75GHz, SO-DIMM socket for up to 8GB DDR3, Dual SATA ports or a mSATA port for a wide variety of storage options, optional mPCIe socket, VGA, 4 USB 2.0, 2 RS-232 serial ports, 2 1GB LAN ports and more.
Existing Configuration 5
Configuration 5 uses a AMD G-series processor with single or dual core from 615MHz to 1.5GHz clock speed, SO-DIMM socket for up to 4GB DDR3, 2 SATA Ports as well as a CFAST socket with locking arm and/or optional flash memory soldered for a wide variety of storage solutions, VGA/LVDS, 4 USB 2.0, up to 4 RS232/422/485 serial ports, 1GB LAN ports and more.
Advanced and Custom Systems
Every application is different, and ACCES can easily tailor a system to a users specific needs. After listening to our customers, ACCES has developed a system design and integration team focused on the development of powerful, yet simple to use, data acquisition systems. These include extensive CPU and peripheral capabilities and the integration of a generous selection of our (or customer-specified) data acquisition, I/O, or special-function PC/104 boards. Custom development can include minor variations of standard boards and systems to completely custom interfaces and configurations. ACCES has the in-house engineering resources to design, develop, supply and support custom embedded systems at the board, software and system level. For more information please visit our System Integration and Custom Hardware Design page.
Military and Defense
The system ships with pre-loaded board software packages containing utility and tools software along with a variety of drivers. Source code and examples in ďCĒ are provided for Linux and DOS, and in a variety of languages for use in Windows versions including XP and beyond. TCP/IP / Internet data acquisition is available via onboard web server software optionally integrated with the customerís application. Any operating system and customerís applications can be pre-loaded for any production volume.
