Hunter EZ-DT Handheld Wireless Diagnostic Tool for EZ Decoder Systems
INTRODUCTION
EZ-DT is a handheld, battery-operated device used for field diagnostics and troubleshooting with Hunter EZ Decoder Systems. Innovative wireless communication from the EZ-DT to EZ-1 decoders permits fault detection in the field 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 flexible options for programming decoders prior to installation or reprogramming existing decoders in the field.
EZ-DT COMPONENTS:
INSTALLING THE BATTERIES
The EZ-DT operates with 4 x AAA batteries (included).
To install batteries:
Remove the battery compartment from bottom of the device. Insert 4 AAA
batteries as shown, observing polarity. Reinsert the battery compartment and
lock it into place (counterclockwise to unlock; clockwise to lock).

DECODER DIAGNOSTICS AND TROUBLESHOOTING
All diagnostic functions are completed via wireless communication between the EZ-DT and EZ-1 decoders. To read decoder information:
- Manually activate the desired station to energize the two-wire path.
- From the Home screen, select Read -> Then position the EZ-DT and EZ-1 decoder as shown in the display -> Then press Enter.
- Two beeps will sound and decoder information will be displayed.
- 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 station is active, check the two-wire path and wire connections, and repeat steps 1 and 2.
PROGRAMMING AN EZ-1 DECODER:
To program an individual EZ-1 decoder, you must connect the red and blue wires from the decoder to the EZ-DT. You can only program one decoder at a time.
- With the EZ-1 disconnected from the two-wire path, insert the red and blue wires from the decoder to the EZ-DT programming ports located under the top cover.
- From the Home screen, select Program -> Then choose Station or P/MV -> Select the desired station number or P/MV output.
- Successful programming of a decoder is confirmed with two beeps and a green check mark.
