DUAL AUTONOMOUS TELEMETRY DATA ACQUISITION SYSTEM AND REAL TIME OPTO-ISOLATED RECEIVERS FOR USE THEREWITH

摘要

A serial digital data acquisition receiver (SDDAR) or system of receivers may include an opto-isolator assembly, sampling logic and a USB interface. Both a CLK signal and a DATA signal may each pass through the opto-isolator assembly upon receipt of the CLK and DATA signals at the SDDAR or system. The sampling logic may be operably coupled to the opto-isolator assembly and be configured to determine a point at which to sample the DATA signal based on state changes in the CLK signal. The USB interface may be operably coupled to the sampling logic and an output terminal. The USB interface may be configured to provide telemetry data for processing, display or recording at the output terminal, and may be configured to enable the SDDAR or system to be powered from the output terminal.

1. A serial digital data acquisition receiver comprising:
an opto-isolator assembly through which both a serial telemetry clock (CLK) signal and a serial telemetry data (DATA) signal pass upon receipt of the CLK and DATA signals at the serial digital data acquisition receiver; sampling logic operably coupled to the opto-isolator assembly, the sampling logic being configured to determine a point at which to sample the DATA signal based on state changes in the CLK signal; and a universal serial bus (USB) interface operably coupled to the sampling logic and an output terminal, the USB interface being configured to provide telemetry data for processing, display or recording at the output terminal, and configured to enable the serial digital data acquisition receiver to be powered from the output terminal.
