Aries

This product is supported for DSCUD 8.0 and above. For DSCUD 7.0 documentation, please refer Aries SBC Universal Driver Software User Manual A0.pdf

Overview

Aries is an embedded single board computer (SBC) with a PC/104-Plus form factor. Aries integrates on-board memory, PC/104-Plus (ISA + PCI) expansion, one PCIe MiniCard socket, dual Gigabit Ethernet, and optional data acquisition circuit with analog and digital I/O.

The Aries SBC is based on Intel “Bay Trail” E3800 series processors. The form factor is similar to PC/104 with left and right side extensions that extend the full length of the two sides without providing the corners traditionally seen in PC/104 boards with “wings”.

Board Initialization

To use the Aries board in an application using the UD, the dscInitBoard function should use the board macro DSC_ARIES. This is shown in the example below...

The base address should be 0x280 and the default IRQ to use is IRQ 5.

dscInitBoard(DSC_ARIES, &dsccb, &board );

Analog Input

Max Input Channels:	16 (single-ended) or 8 (differential)
A/D Resolution:	16 bits (1/65536 of full-scale)
Data range:	-32768 to +32767 for all voltage ranges
Input Ranges (Bipolar):	±10V, ±5V, ±2.5V, or ±1.25V
Input Ranges (Unipolar):	0-10V, 0-5V, or 0-2.5V
Supported Conversion Triggers:	Software, External digital signal
Maximum Conversion Rate (Software Command):	approx. 250,000 samples per second, depending on code and operating system
Maximum Conversion Rate (Interrupt Routine w/FIFO):	100,000 samples per second
FIFO:	2048 samples with Programmable interrupt threshold

Analog Output

Max Output Channels:	4
D/A Resolution:	15 bits (1/65536 of full scale)
Data range:	0 to 65535 for all voltage ranges
Bipolar Output Ranges:	±10V, ±5V, ±2.5V
Unipolar Output Ranges:	0-10V, 0-5V

Digital I/O

Max Ports:	3, bi-directional, programmable in 8-bit groups.Digital I/O ports on Prometheus require direction to be set with DscDIOSetConfig() before use. All DIO lines power-up in input mode and have readback capability. All DIO lines have r external configurable pull resistors that can be configured for all pull-up or all pull-down with a jumper.
