EZ-DT Handheld Wireless
Diagnostic Tool for Hunter
EZ Decoder Systems
Quick Start Guide
INTRODUCTION
EZ-DT is a handheld, battery-operated device used for eld diagnostics and troubleshooting with Hunter
EZ Decoder Systems. Innovative wireless communication from the EZ-DT to EZ-1 decoders permits fault
detection in the eld without removing the decoders from the two-wire path.
Use EZ-DT to quickly and easily retrieve a decoder’s status, station address, current draw, and voltage on the
two-wire path.
EZ-DT can also be used to program station addresses into EZ-1 decoders via the red and blue wired
connection to the decoder. This capability provides exible options for programming decoders prior to
installation or reprogramming existing decoders in the eld.

2. From the Home screen, select Read -> Then position the EZ-DT and
EZ-1 decoder as shown in the display -> Then press Enter.
3. Two beeps will sound and decoder information will be displayed.
4. If the decoder reading fails, a red X will appear in the display.
If the LED on the decoder is not blinking green, ensure the
