From Tester To Dashboard - Without the wait!

The Tester Monitoring Daemon (TMD) is a lightweight, high-speed data snooper designed to operate directly on your test equipment—no extra hardware, no floor space required. TMD captures STDF data streams in real time and transmits them seamlessly to your SMART Server, enabling instant visibility into production metrics and test outcomes.

But it doesn’t stop there. TMD also monitors GPIB or Parallel/TTL communication traffic, extracting key performance data without disrupting your test flow. Its non-intrusive architecture ensures zero impact on throughput, while its rapid data relay keeps your monitoring systems fully up to date.

Whether you're tracking yield, cycle time, or equipment health, TMD delivers the data you need - fast, clean, and in real time.

  • Real Time GPIB, Parallel/TTL or STDF Snooper
  • No Floor Space Required
  • Runs on Tester
  • Sends Data to OEE Server for RealTime Monitoring
