    1.1.3. Overview 1.1.3.1. Technical Details The EUROCOM 248 is an Intel Pentium III single-board computer with a CompactPCI interface, optimized for real-time applications, while maintaining full PC compatibility. This is the ideal platform for industrial applications with real-time operating systems, extending ELTEC’s successful BAB product line for Intel...
  • Page 10 1.1.3.1.4. Graphics Interface The graphics interface of the EUROCOM 248 is the graphics controller of the 815 chip set. It can display up to 1280 x 1024 pixels in true color (24 bpp). Since it uses an unified memory graphics frame buffer, there is a trade-off between the bandwidth used for display and for CPU access.
  • Page 11 1.1.3.1.6. Ethernet Interfaces The two network interfaces on the EUROCOM 248 use the network controller i82559ER for 10/100 Mb connectivity with the 10BaseT or 100BaseTX standards. Optionally, one or both port can be ordered with 1 Gb capability (i82540). Remote boot from LAN is supported.

  • Page 13: Installation

    1.2.2. SO-DIMM Installation If the EUROCOM 248 is not shipped with DRAM SO-DIMMs, the user must insert his own SO-DIMMs on the board. The EUROCOM 248 is not able to run without DRAM. SO-DIMM installation can be done easily. The board has one SO-DIMM socket, X401. The BIOS software detects automatically if the bank is populated.

    Chapter 1. Hardware part 1.2.3.3. Mouse A standard PS/2 mouse can be connected to X802 using a splitadaptor. 1.2.3.4. Serial A serial device can be connected directly to X805. The interface supports speed up to 115200 kb/s. 1.2.3.5. Ethernet A Network can be connect using 10BaseT, 100BaseTX or 1000BaseT standard. It can be connected to X808.

  • Page 15: Bios Setup

    The EUROCOM 248 is delivered with an EMBEDDED BIOS from GENERAL SOFTWARE. The BIOS includes a setup menu to configure basic settings. ELTEC ships the EUROCOM 248 with optimized BIOS settings. If desired, most of the BIOS settings can be changed (some settings are hardwired). Also if the battery for the CMOS RAM is weak, the RAM may loose its contents making a new setting of the setup necessary.

  • Page 16: Testing The Installation

    Chapter 1. Hardware part 1.2.6. Testing the Installation After power is switched on the BIOS displays a message on the CRT screen. It takes some time before the BIOS is ready to display. After system boot from harddisk or floppy drive the keyboard should work. The driver software for the mouse should detect the mouse device.
