EZ-DT - Handheld Wireless Diagnostic Tool

The EZ-DT is a handheld, battery-operated device used for field diagnostics and troubleshooting with 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. 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 provides flexible options for programming decoders before installation or reprogramming existing decoders in the field.
