 Description

 The Data Acquisition System (DAS) is a stand-alone system, which provides data format conversion of digital, analog, serial, synchro, and resolver signals.

 The DAS is factory configurable to customer requirements for easy field installation.

An DAS is available in rugged EMI/EMC enclosures.

Applications
  • Radar Systems (antenna azimuth)
  • Navigation Systems  (gyrocompass, speedlog, course, pitch, and roll)
  • Industrial Processes    (position, velocity)
  • Meteorology Instruments (wind speed and direction)
  • Many Others

Features

  • NEMA-0183 Compatible
  • Optional LCD Display
  • 90V, 11.8V Synchro, 6.8V Resolver
  • RS-232, RS-422, RS-423, RS-485, MIL-STD-188C Protocols
  • Custom Serial Data Formats and Frequencies are available upon request

 

 

Card Layout  

 

The DAS is capable of interfacing to two synchro/resolver, two serial, sixteen digital and two analog interfaces.

Overview

The Data Acquisition System (DAS) is a stand alone system which interfaces to several types of analog and digital inputs and outputs (I/O).  An onboard microcontroller controls the processing of these signals to provide conversion to user requested outputs.  An optional LCD display enables display of raw or converted data.

 During power up or reset, an onboard microcontroller reads the configuration switch, configures the interface card, and provides all signals and control necessary to read the desired interface, process and display the data, and output the converted information. 

Examples of uses include: radar systems (antenna azimuth), navigation systems (gyrocompass, speedlog, course, pitch, and roll), industrial processes (position, velocity), and meteorology instruments (wind speed and direction).

 

 

Input/Output

Inputs and outputs are available on circular connectors provided with the DAS. Inputs and outputs are listed below: 

 

 

 Serial Interfaces

Serial data interfaces use the standard National Marine Electronics Association(NMEA) message formats NMEA-0183 as shown below.  This I/O is available in RS-232, RS-422, RS-423, RS-485, or MIL-STD-188C protocols. Standard output update rate is once per second.  Custom serial data formats and frequencies are available upon request.

Serial baud rate selection and checksum checking is determined from the configuration switches at power up or reset.  Selectable baud rates include:  2400, 4800, 9600, 19,200 and 38,400 bits per second. Default data output is 9600, 8 bits, no parity, and one stop bit (9600, 8, N, 1). Table 3 defines the switch position for the available baud rates.

NMEA-0183 Format

The DAS can be factory programmed for any NMEA-0183 data format.  Default data format is as follows:

 

$PTBBG,AAA.AA,BB.B,C,D,EEE.E,FF.F,G,HA*CSCRLF

 

$ - start of message ascii character 24 Hex

PT - Proprietary message

BBG - BBG Incorporated

AAA.AA - channel 1 angular information (ex: 045.01)

BB.B channel 1 analog information (ex: 08.4)

C channel 0-3 hexidecimal digital information (ex: 7) Note: 7 = 0111

D channel 4-7 hexidecimal digital information (ex: E) Note: E = 1110

BBG - BBG Incorporated

EEE.EE - channel 2 angular information (ex: 270.24)

FF.F channel 2 analog information (ex: 10.0)

G channel 8-11 hexidecimal digital information (ex: 5) Note: 5 = 0101

H channel 12-15 hexidecimal digital information (ex: E) Note: A = 1010

A - validity (A = valid, V = Invalid)

* - ascii character 2A Hex

CS - checksum (8 bit XOR of characters between $ and *

CR - carriage return

LF - Line feed

  

 

Synchro/Resolver Interfaces

Synchro/Resolver Inputs:         

 Inputs are jumper selectable for synchro or resolver signals and can be configured for any desired voltage by a simple chip/resistor replacement.  Synchro or resolver inputs are fused and transient protected.  Standard voltages include 90Vrms, 26 Vrms, and 11.8Vrms synchro inputs and 6.8 Vrms resolver inputs over the frequency range of DC to 40kHz.  Custom voltages are available upon request.  Please specify desired voltage when ordering DAS.

 

Synchro/Resolver Outputs:       

 Outputs are factory configurable for synchro or resolver signals at any required voltage and frequency.  Please specify desired voltage and frequency when ordering card.  Synchro/resolver outputs are reference powered.

 

 

 

 

Analog Interfaces

Analog Inputs: 

 Inputs are factory configurable for full scale ranges of -10V to +10V. Custom ranges are available upon request. Please specify desired voltage range when ordering UCE.
