Page 4: Important Safe Handling Information
The list here describes common causes of failure found on boards returned to Diamond Systems for repair. This information is provided as a source of advice to help you prevent damaging your Diamond (or any vendor’s) embedded computer boards. - Page 5 Overvoltage on analog input – If a voltage applied to an analog input exceeds the design specification of the board, the input multiplexor and/or parts behind it can be damaged. Most of our boards will withstand an erroneous connection of up to 35V on the analog inputs, even when the board is powered off, but not all boards, and not in all conditions.

Page 6: Introduction
2. INTRODUCTION Aries is an embedded single board computer (SBC) in the PC/104 form factor. Aries integrates on-board memory, PC/104-Plus expansion, one PCIe Mini card 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”. -

The A/D section includes a 16-bit A/D converter, 16 analog input channels and a 2048-sample FIFO. Input ranges are programmable, and the maximum sampling rate is 250 KHz. The D/A section include 4 16-bit D/A channels. The digital I/O section includes up to 22 lines with programmable direction. -
Page 36: Fpga
10.2 FPGA FPGA provides all logic functions of the Aries baseboard data acquisition as well as a watchdog timer and a power sequencing circuit. The chip also interfaces to a Renesas encryption chip for future security features. The following table shows a list of all the features offered by Aries FPGA. Feature Description A/D channels... - Page 37 ADINT=1 and an interrupt occurs when ADINTEN=1 and one of the following occurs: FIFOEN SCANEN Action Interrupt occurs after each A/D conversion completes (ADBUSY goes low). Interrupt occurs after each A/D scan completes (ADBUSY goes low). Interrupt occurs when A/D conversion completes and FIFO threshold is reached or exceeded.
-
Page 38: A/D Circuit
11. A/D CIRCUIT 11.1 A/D Input Ranges and Resolution Aries uses a 16-bit A/D converter. This means that the analog input voltage can be measured to the precision of a 16-bit binary number. The maximum value of a 16-bit binary number is 216 - 1, so the full range of numerical values that user can get from Aries input channel is 0 - 65535. -
Page 39: Conversion Formulas
11.3.1 Conversion Formulas The 16-bit value returned by the A/D converter is always a two’s complement number ranging from -32768 to 32767, regardless of the input range. This is because the input range of the A/D is fixed at ±10V. The input signal is actually magnified and shifted to match this range before it reaches the A/D. -
Page 40: A/D Sampling Methods
11.3.1.2 CONVERSION FORMULA FOR UNIPOLAR INPUT RANGES Input voltage = (A/D code + 32768) / 65536 * Full-scale input range Example: Given, Input range is 0–10V and A/D code is 17761. Therefore, Input voltage = (17761 + 32768) / 65536 * 10V = 7.7103V. For a unipolar input range, 1 LSB = 1/65536 * Full-scale voltage. -
Page 41: Scan Sampling
Note: If both scan and FIFO operations are enabled, the interrupt occurs at the programmed FIFO threshold and the interrupt routine reads the indicated number or samples and then exits. This happens even if the number of samples is not an integral number of scans. For example, if the user has a scan size of 10 and a FIFO threshold of 256, the first time the interrupt routine runs, it reads 256 samples, consisting of 25 full scans of all 10 channels followed by 6 samples from the next scan. -
Page 42: D/A Circuit
Interrupt Used for controlled-rate sampling of single channels or Single multiple channels in round-robin fashion, where the Conversion, frequency of sampling must be precise but is relatively slow Low Speed (<100Hz). The sampling clock comes from the on-board counter/timer or from an external signal. The interval between all A/D samples is identical. -
Page 43: Resolution
DAC supports is 0 - 65535. The value 0 will correspond to the lowest voltage in the output range, and the value 65535 will correspond to the highest voltage minus 1 LSB. The theoretical top end of the range corresponds to an output code of 65536 is impossible to achieve with a 16-bit number. -

Page 45: Calibration
All analog outputs power up to 0V for safety. If recalibration or calibration for nonstandard D/A ranges are needed, please contact Diamond Systems for technical support. All analog components contain inherent errors in offset and gain which affect the accuracy of the signals they generate. -
Page 46: Digital I/O
13. DIGITAL I/O The FPGA has three digital I/O ports named A, B, and C. The DIO is organized as follows in the FPGA: Port A = 8 bits with 1 bit for direction control of the entire port (DIRA) Port B = 8 bits with 8 bits for direction control (DIRB[7:0]) Port C = 6 bits with 6 bits for direction control (DIRC[5:0]) A 0 means input mode and a 1 means output mode. -
Page 47: Counters And Timers
14. COUNTERS AND TIMERS The FPGA contains 8 32-bit up/down counter timers with programmable functions. The counters are programmed using a command register at address 5 in the counter block, a counter number register at address 4, and a 32-bit data register CTRD31-0 at addresses 0-3. -
Page 48: Pulse Width Modulation
15. PULSE WIDTH MODULATION Aries supports 4 24-bit PWM circuits. The PWMs are programmed using a 24-bit PWM data register PWMD23-0 and an 8-bit command register PWCMD3-0 + PWM2-0 + PWMCD. Each PWM consists of a pair of 24-bit down counters named C0 and C1. The C1 counter defines the duty cycle (active portion of the signal), and the C0 counter defines the period of the signal. -
Page 49: Watchdog Timer
16. WATCHDOG TIMER The watchdog timer can be used to trigger an interrupt or system reset upon the expiration of a programmed time interval. The purpose of this timer is to enable the system to recover from a software or hardware error that causes the system to freeze or get caught up in a software infinite loop. -
