ELEKTRA
High-Performance Rugged Embedded CPU with Data Acquisition
1. DESCRIPTION
ELEKTRA is an embedded CPU board in standard PC/104 form factor that integrates a complete
embedded PC, consisting of the following subsystems onto a single compact board:
♦
CPU
♦
Core PC Chipset (including memory controller, PCI interface, and ISA interface)
♦
128 MB system memory
♦
10/100
Ethernet
♦
Analog and Digital I/O
A detailed list of features is shown on the next page.
The single board ELEKTRA computer is a Pentium II class device with onboard central
processing, memory and memory management devices and I/O management for specific
functions. It conforms to the PC/104 standard, an embedded standard that is based on the ISA
and PCI buses and provides a compact, rugged mechanical design for embedded systems.
PC/104 modules feature a pin and socket connection system in place of card edge connectors, as
well as mounting holes in each corner. The result is an extremely rugged computer system fit for
mobile and miniature applications. PC/104 modules stack together with 0.6” spacing between
boards (0.662” pitch including the thickness of the PCB). The computer communicates externally
via an ISA bus as well as the specified I/O ports. The single board computer is powered from an
externally reg5VDC (+/-5%) supply.

Elektra uses the PCI bus internally to connect the Ethernet circuit to the processor. It uses the
ISA bus internally to connect serial ports 3 and 4, as well as the data acquisition circuit, to the
processor. Only the ISA bus is brought out to expansion connectors for the connection of add-on
boards. Diamond Systems manufactures a wide variety of compatible PC/104 add-on board for
analog I/O, digital I/O, counter/timer functions, serial ports, and power supply.
The Elektra is mean to be a direct replacement upgrade for the Prometheus and is backwards
compatible.
