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 133 MHz AMD ELAN520 processor and integrates all the standard functions of a PC. Memory of 16-128 MB SDRAM in SODIMM socket is offered and the system includes DiskOnChip and CompactFlash sockets facilitating easy upgrade of embedded programming. Optional on-board CRT/LVD interface allows connection to a CRT and/or 3V/5V flat panels via 24-bit TFT LCD interface.
|Standard Configuration 1A
|Built upon our standard configuration. 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 10/100BaseT Ethernet, keyboard and mouse, four 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, 4xUSB2.0, 2xRS-232 COM ports, PS/2 keyboard and mouse, parallel printer, AC97 sound, 10/100MBit LAN and more.
|Existing Configuration 3
|Configuration 3 uses a jumper selectable 233 or 300 MHz AMD Geode GX1 CPU with CS5530A companion chip. Features include: 256 KB SMT flash contains BIOS, SO-DIMM socket for up to 256 MB SDRAM, CompactFlash drive accepts Type 1 or Type 2 devices, and the integration of video, RS-232/422/485 serial ports, parallel port, digital I/O, dual USB ports and more.
|Existing Configuration 4
|Configuration 4 features an Intel Celeron 300 MHz PC/104-Plus CPU and offers high reliability and low power consumption. Optional Intel Pentium III 500 MHz or 700 MHz are also available for this system. PC/104-Plus form factor allows for graphics and high-speed I/O devices. A SO-DIMM socket allows up to 512 MB SDRAM and integrated graphic controller supports LVDS and JILI and has up to 32 MB of graphics memory. Includes standard peripheral interfaces.
|Existing Configuration 5
|Our best value, economical workhorse. Featuring a tried and true 133 MHz 486 engine. Includes DiskOnChip (DOC) supporting up to 288 MB flash memory for local OS and application programming. Fully adequate for most Ethernet I/O applications without limiting throughput.
|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.
