1. Overview
2.4G Hz long distance reading system employs the ISM microwave. The reflection of
radio waves can be helpful in transmitting a radio signal over long distances in high
speed. Active RFID tags have their own internal power source, which is used to power
the integrated circuits and broadcast the signal to the reader. If the reader has received
the signal from tag, the reader will send the data to the server computer for data
processing.
1.1 LED status of the BG-245/W UHF RFID Reader
Green LED: Flashing once per second: the reader is working properly.
Red LED: Flashing once per 2 seconds: a tag has been read.
1.2 Audio Signal of the BG-245/W UHF RFID Reader
1 beep: a new tag has been read by the reader.
Note:
when a tag has been read once, if it remains in its reading distance, the tag will
not trigger the buzzer again; if the tag is moved beyond its reading distance and then
moved within its reading distance later on, the reader considers it is a new tag and will
emit 1 beep.

2.1 Wire Definitions
The 6-core wire for external connection has the following color in sequences: red,
black, white, green, yellow, and blue. The red and black wires are for power source.
When the power source is DC, the black wire is ground wire; when the power source
is AC, there is no sequence for the red and black wires.
