EPIC SBC has USB 2.0, Gb-Ethernet, SATA and DAQ

18 April 2007 Computer/Embedded Technology

Diamond Systems’ Poseidon is a high performance EPIC form-factor (115 x 165 mm) single board computer combining a state-of-the-art CPU and peripheral technology with the company’s renowned high accuracy data acquisition circuitry on a single board.

This SBC uses the new Via C7 and VIA Eden ULV processors operating at speeds up to 2,0 GHz with up to 512 MB RAM and a 400 MHz FSB.

The Poseidon SBC is claimed to be extremely rugged, featuring soldered DRAM, optional hardwired jumpers for increased resistance to shock and vibration and an operating temperature range of -40 to +85°C without a fan for the 1,0 GHz model.

A broad set of system I/O includes Gigabit Ethernet, four RS232 ports (two with RS422/485 capability), four USB 2.0 ports, S-ATA and IDE controllers, PS/2 keyboard/mouse, an advanced 2D/3D video controller with integral MPEG-2 hardware acceleration supporting both CRT and LVDS flat panel displays and AC'97 sound with amplified speaker output.

Poseidon's optional data acquisition section has 32 16-bit analog inputs with a 250 kHz sample rate along with 4 12-bit D/A channels. Autocalibration on both A/D and D/A ensures maximum accuracy over time and temperature without user intervention. It supports both interrupt and DMA A/D transfers, and it uses an enhanced 1024-sample FIFO with programmable threshold for maximum flexibility and data reliability.

Poseidon II provides 24 digital I/O lines with programmable direction, as well as two counter/timers for A/D sample rate control, pulse counting, frequency generation, or other applications.

All Poseidon I/O is brought to pin headers along the edges of the board. Universal driver software for Linux, Windows 98/2000/XP/CE, DOS, QNX, and VxWorks is included.
