The EET-200
Encoder Emulator Tester
by Trans-Cal Industries

The EET-200 End the shotgun approach to troubleshooting and reduce the time spent in diagnosing altitude encoder/transponder problems. TRANS-CAL INDUSTRIES' EET-200 offers the avionics technician an inexpensive diagnostic tool for altitude encoder/transponder troubleshooting. Open or shorted wire in your encoder harness? A bad input gate on the transponder? Why waste time jumping individual data bits to ground using a clip lead and paper clip? The EET-200 provides the avionics technician a clean, quick, and reasonably priced method of emulating an altitude encoder output by providing a known good altitude code source to aide in isolating each data bit D2 through C4. Simply unplug the altitude encoder and substitute the EET-200; rotating the knob will move the transponder through a variety of preprogramming altitudes testing each data bit in sequence. Suspect a problem with the altitude encoder? Unplug the encoder and plug both the transponder and the encoder into the EET-200. Use the built-in vacuum syringe to simulate any altitude from sea level to over 30,000 feet (using supplied 12" x 1/8" tubing, not pictured). Compare the encoder output to the supplied altitude code chart to determine if an error is present. Strobe function not working? Simply toggle the strobe switch on the EET-200 to simulate an open strobe on the digitizer or the transponder. Power supply connected correctly? Simply unplug the altitude encoder and substitute the EET-200. If the power LED glows green, then you are good to go. If it glows red, then you power is hooked up improperly. Simple, Clean, Compact, and almost indestructible. Put the EET-200 in your toolbox today! Click Here for a Specification Sheet on the EET-200
