  • EZ-Tap Pro™
    RS-232 Passive Tap Module - Bus Analyzer / Protocol Analyzer

    Stratus Engineering's EZ-Tap Pro hardware module RS232 sniffer is a sophisticated protocol analyzer and bus analyzer hardware solution that overcomes latency and time-tagging problems associated with traditional dual COM port monitoring solutions.

    EZ-Tap Pro features state-of-the art electronics that provides extended functionality:
    • Exact hardware microsecond time tagging of all RS232 data and handshaking events
    • Captures and time tags state changes on all 6 RS-232 handshaking lines
    • Supports baud rates up to 921600 bps
    • Supports 3.3V/5V TTL and RS232 voltage levels
    EZ-Tap Pro offers these capabilities at a fraction of the cost of the nearest competitor and is available in the same small, convenient mechanical form factor as the original EZ-Tap module.

    Stratus Engineering's EZ-View monitoring program fully supports EZ-Tap Pro and is available free of charge from our downloads page.
