Introduction
Tag Reader is a device that is designed to operate in conjunction with a Tag and a Signpost. Basic Tag
Reader functionality is shown in diagram below:
The Signpost generates modulated RF signal at 125 kHz frequency, which is detected by the Tag. Upon
detection of Signpost signal, the Tag transmits its own signal on 434 MHz frequency to one or more Tag
Readers. Tag Readers process information and based on internal database, they activate outputs while
simultaneously passing information to the Server computer which is running application software.
There are two types of tag Readers: Tag Reader Door Controller and Tag Reader Receiver.
Tag Reader Receiver is used when only to collect all the messages from the Tags and pass them toi the
Server. Tag Reader Door Controller has the same functionality, but additionally, it is used for perimeter
protection by controlling the door it is assigned to.
Installation
Position
The main function of a Tag Reader is to receive RF communication from Tags. It is important to select
carefully mounting location of the Tag Reader which will not interfere with a capability of the device to
receive RF messages from the Tags. This is accomplished by avoiding mounting in the proximity of metal
objects, cables, electrical devices, etc.
