SES Solid State Data Recorder - Expandable Range

The S3DR product family is a low cost, high performance, rugged solution to the processing and data recording needs of environmentally challenging embedded systems, such as those found in aerospace, defence, naval, vehicle and safety-related or high performance industrial applications.

The Solid State Data Recorder - Expandable (S3DR-E) is a high-speed, high capacity expandable data recorder with extensive data acquisition and communications flexibility. The recorder is built from the concept of multiple recording, data acquisition and communication modules that are assembled together to provide a system that meets the specific bespoke requirements of a customer application.

The recorder always contains a master processor module which provides control and configuration of any other modules contained in the system. This master processor provides a high-performance general purpose processor that controls all other data acquisition, recording and communication modules. The processor module also provides multiple high-speed USB 2.0, Giga Ethernet and VGA interfaces.

A minimum S3DR-E recorder is built from a master processor combined with a recording module and an integrated power supply. Alternative recorder configurations can be built from any combination of up to seven data acquisition, communications and recording modules.

• Recording Modules: Each recording module can be built from either a dual PCMCIA recorder with a dedicated I/O processor, or a high capacity (100 Gbyte), high speed (up to 480Mbits per second) dedicated recording module.
• Data Acquisition: The available data acquisition modules include high-speed A/D converters, video (Mpeg2), thermocouples, RTDs and strain gauges.
• Communications: The communications modules supported include 10/100/1000 Ethernet, 1553-B, Arinc-429, NTDS-E, RS422/485, CAN bus, Synchro and IRIG-106 (PCM).

S3DR-E: A/D Converter

The S3DR-E A/D Converter module provides an exceptional performance simultaneous-sampling, high-bandwidth capability for low and high-channel-count data acquisition and control systems. The SES S3DR-E A/D Converter module supports up to 4 channels of continuous high-speed data logging at 10 MS/s, 8 digital I/O lines, 2 counter/timers and 2 analogue outputs.

The module is typically used in the following types of applications:

• Radar, sonar.
• Synchronisation between high speed analogue input (AI), analogue output (AO), and digital I/O is required.
• In 42 V automotive applications
• Transient/ballistics measurements
• Highly accurate time/frequency domain measurements - as little as 6 µV of noise, as much as 90 dB spurious-free dynamic range

S3DR-E A/D Converter Module Key Features

• Dedicated A/D Converters per Channel: For faster sampling rates per channel (up to 10 MS per second), 12 Bit resolution, simultaneous sampling, and better dynamic accuracy for transient or frequency measurements 200 mV to 42 V Input Ranges - configure each analogue input channel to read from a very wide variety of voltage ranges. The input impedance is lower for 20 and 42 V ranges, preserving the bandwidth for signals with high frequencies and large amplitudes.
• AC or DC Coupling: Analogue inputs can be configured for AC or DC coupling on a per-channel basis. AC coupling removes the DC offset for applications only analysing signals in the frequency domain.
• Antialias Filters: The antialias filters are turned on from software on a per-channel basis. The module has 50 or 500 kHz filters for each channel.
• Large Onboard Memory: The module features a 64 or 32 Msample onboard memory.
• Hardware-Timed Digital I/O: The digital I/O lines can synchronize with the analogue input, analogue output, counter/timer I/O, or an external clock for mixed signal measurement applications. Using the onboard FIFO, the module can achieve reliable data transfers to 10 MBytes/s.
• Phase Locking: Multiple devices can be synchronized to a common backplane clock to preserve the phase between measurements across multiple device analogue input channels.

S3DR-E: Digital to Synchro Converter

This S3DR-E module contains four separate transformer isolated Digital-to-Synchro/Resolver converters (1.2VA), optional 5 VA reference, and extensive diagnostics. The (4) Stimulus channels include ON/OFF output capability; individual reference inputs are supplied for each channel, two-speed programmability, and rotation with start and stop angles. The Stimulus channels offer short circuit protection and the ability to ground one of the outputs without affecting performance.

External amplifiers can be added to drive up to 30 VA with a frequency range of 50 to 400 Hz. Each channel can be specified for a different voltage, frequency or resolution. To simplify logistics, Part number, S/N, Date code, & Rev. are located in permanent memory locations

Features

• 16 bit resolution
• 30 arc seconds accuracy
• Output format Synchro or Resolver
• Continuous background bit testing for Reference and Signal loss detection
• Power-On Self-Test (POST)
• 360Hz to 10kHz
• Transformer isolated
• No adjustments or trimming required
• 2 or 4 channels available
• Rotation: Programmable Start and Stop angles. 0 rps to ±13.5 rps with a resolution of 0.15°/sec

Major diagnostics are incorporated that offer substantial improvements to system reliability because the user is immediately alerted to channel malfunctions. This approach also reduces bus traffic because the Status Registers do not require constant polling. Power-On, Self-Test (POST) diagnostic can immediately initiate (D3) test.

Two different tests (one on-line and one off-line) can be selected:

The (D2) Test initiates automatic background BIT testing that checks the output accuracy of each channel, by comparing the measured output angle, before the output transformer, to the commanded angle. The status bits will be set to indicate an accuracy (0.05%) problem and the results can be read from D/S Test Status Register.

In addition, each Signal and Reference is continually monitored. Any failure triggers an Interrupt (if enabled) and the results are available in the Signal and Reference status registers.

The (D3) or POST test, (if enabled), starts a BIT Test that generates and tests 72 different angles, to a testing accuracy of 0.05°. Results can be read from Status Registers. External reference is required. Testing requires no external programming, and can be Initiated or terminated via the bus. CAUTION: Outputs are active during this test. Check connected loads for possible interaction.

S3DR-E: Synchro to Digital Converter

This S3DR-E module provides eight (8) transformer isolated Synchro/Resolver-to-Digital tracking converters that are programmable for either single speed or two-speed mode, extensive diagnostics, velocity outputs, angle change alert, and optional programmable reference supply. Each channel also produces differential incremental encoder (A&B) outputs (with programmable resolution) and a zero degree marker pulse. Commutation outputs are available for 4, 6, or 8 pole brushless DC motors that eliminate the need for Hall Effect sensors on the motor thus eliminating processor time and reducing bus traffic.

Features

• 16-bit resolution for single-speed (up to 24 bits for two-speed configuration)
• Accuracy: 1 arc minute for single-speed. 1 arc minute divided by gear ratio for two-speed
• Gear ratio: Each channel pair is programmable from 2 to 255
• Continuous background testing with Reference and Signal loss detection
• Power-On Self-Test (POST)
• Self-calibrating. Does not require removal for calibration
• Synchro/Resolver programmable input source
• Either two-speed or single speed configurable
• Watchdog timer and soft reset
• Accurate Digital Velocity outputs
• Angle change alert
• 47Hz to 10Khz options available
• Transformer isolated
• Synthetic reference compensates for ±60° phase shift
• Latch feature
• No adjustments or trimming required

In the two-speed configuration any ratio between 2 and 255 can be selected. Ambiguity circuits maintain monotonic outputs by compensating for variations of the zero positions between the Coarse and Fine synchros. The card also checks the angle difference between the Coarse and Fine synchros and will set a flag when the max. allowable angle difference of 90°/n is exceeded.

The S/D channels, even when large accelerations are encountered, never lose tracking, because they incorporate the unique capability to automatically shift to higher bandwidths. The shifting is smooth and continuous with no glitches. Tracking rates are only limited to bandwidth restrictions, up to 150RPS, at 16-bit resolution. The "Latch" feature permits user to read all channels at the same time. Reading will unlatch that channel. The angle alert monitors each channel for the programmed angle difference and sets an interrupt as soon as that threshold is reached. Thus, no polling of the angle registers is required until an angle has reached the specified difference.

Programmable Synchro/Resolver capability can be specified. The use of Type II servo loop processing techniques enables tracking, at full accuracy, up to the specified rate. A step input will not cause any hang-up condition. Intermediate transparent latches, on all angle and velocity outputs, assure that valid data is always available without interrupts or waiting time.

On-Board Diagnostics

Major diagnostics are incorporated that offer substantial improvements to system reliability because user is immediately alerted to malfunctions. This approach also reduces bus traffic because the Status registers do not require constant polling.

Power-On, (POST) diagnostic can immediately initiate (D3) test. Three different tests(one on-line and two off-line) can be selected:

The (D2) test initiates automatic background BIT testing. Each channel is checked every 5° to a testing accuracy of 0.05° and each Signal and Reference are always monitored. For two-speed applications, a flag will be set when the max. allowable angle difference of 90°/n is exceeded. Any failure triggers an Interrupt (if enabled) and the results are available in status registers. The testing is totally transparent to the user, requires no external programming, has no effect on the standard operation of this card and can be enabled or disabled via the bus.

The (D3) or POST test, if enabled, starts an initiated bit test that disconnects all channels from the outside world and connects them across an internal stimulus that generates and tests 72 different angles to a test accuracy of 0.05° and results can be read from registers. External reference is not required. Any failure triggers an Interrupt(if enabled). The testing is totally transparent to the user, requires no external programming, and can be enabled or disabled via the bus. Power-On (POST) test can be enabled or disabled via the bus.

The (D0) test is used to check the card and the interface. All channels are disconnected from the outside world, allowing user to write any number of input angles to the card and then read the data from the interface. External reference is not required.

S3DR-E: CAN Bus

The S3DR-E CAN module provides a complete CAN bus interface using the Intel 82527 CAN controller. The Intel 82527 CAN controller supports the standard data and remote frame as well as the extended data and remote frame according to CAN specification 2.0 part A and part B. It has the capability to transmit, receive and perform message filtering on extended and standard messages.

The CAN protocol uses a multi-master (contention based) bus configuration for transfer of "communication objects" between nodes of the network. This multi-master bus is also referred to as CSMA/CR, or "Carrier Sense, Multiple Access, with Collision Resolution." The Intel 82527 CAN controller performs all serial communications functions such as transmission and reception of messages, message filtering, transmit search and interrupt search, with minimal interaction from the host S3DR-E.

The physical interface is a fault tolerant CAN transceiver, which supports the communication between the CAN protocol controller and the physical bus. The interface is optically isolated from the CAN controller. The fault tolerant CAN transceiver supports transmission capability on either bus wire, if one of the bus wires is corrupted. The failure detection logic automatically selects a suitable transmission mode. The S3DR-E CAN module is designed for fault tolerant CAN applications (based on Philips fault tolerant CAN transceiver TJA1053 or similar types) with up to 32 nodes and a baud rate up to 125kbaud.
