PROMETHEUS
High-Integration PC/104 CPU with Ethernet and Data Acquisition
1. DESCRIPTION
Prometheus is an embedded PC/104 CPU that integrates 3 separate circuits onto a single
compact board:
♦
CPU
♦
Ethernet
♦
Analog I/O (optional, model PR-Z32-EA only)
A detailed list of features is shown on the next page.
Prometheus 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). A mechanical drawing of a standard
PC/104 board is shown on page 74.

Prometheus 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.
