KS232DU / KS485DU / KS232DF / KS485DF
RFID Computer Access Controller and Time Recorder
INTRODUCTION
The KS232DU / KS485DU / KS232DF and KS485DF proximity readers are cost effective
solutions for access control and time recording solutions. While connecting them to the
computer and running the Time Recorder software (in Windows), the program will stamp the
date, time and card ID into the computer database, show up the associated picture with the
specific ID on the computer screen, capture the photo if a PC camera is connected to the
computer and release the electric lock if allow access.
A 9 to 12V DC supply is required to power the reader, which has a current consumption of less
than 300mA.
