1. I MPORTANT N OTES
The PRT-LT reader can be configured for several data output format however the factory shipped
new unit is pre-configured for RACS address ID=0. If required reader can be reconfigured
manually using Memory Reset procedure. Comparing with PRT-EM series access terminals the PRT-
LT series readers doesn’t support standalone operating mode.
Note: If after power up the LED SYSTEM is lit and accompanied with repeated sound it means
that contents of reader’s memory is corrupted. In this case reader must be initialized and
configured from the scratch.

2. G ENERAL D ESCRIPTION
The PRT-LT readers have been designed for use in access control installations to enable user
identification via EM 125 KHz (and compatible) proximity cards and/or PIN-s. The PRT-LT reader
works as a slave unit serving a sole purpose of reading cards/PIN-s then providing subsequent
transmission of such collected data to host ACU for further processing. Reader offers several data
transmission formats including popular Wiegand/Magstripe data protocols.
