2.45 GHz RFID ANTENNA
User Manual – BG245 pag. 3 may 09
1 OVERVIEW
2.45 GHz long distance reading system employs the ISM microwave technology.
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. This antenna is suited for any “hands-free” access control system.
1.1 LED STATUS OF THE BG245 RFID READER
Green LED
Flashing once per second: the reader is working properly (stand-by).
Red LED
Flashing once per 2 seconds: a tag has been read (detection).
1.2 AUDIO SIGNAL OF THE BG245 RFID READER
1 beep: a new tag has been read by the reader.
Note: after 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 CONNECTING YOUR RFID ANTENNA
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.
BG245 Reader Wire Definitions
Color Definition
Red Power (+)
Black Power (-) / GND
White Control Signal Input
Green Control Signal Input (GND)
Blue Wiegand Output DATA 1
Yellow Wiegand Output DATA 0
Note: the GND wire of the BG245 must connect with the GND line of the Wiegand controller;
otherwise, the communication network cannot be established. White wire and Green wire are
welded together to enable the reader to read tag. Alternatevely the White and Green wire must be
connected to an external trigging device (i.e. loop detector IG315/325) according to the application.
2.1 ADJUSTING READING RANGE
The reading range is adjustable from 1 to 35 meters and depends on the types of tags. This can be
done by adjusting the potentiometer at the bottom of the antenna (refer to the picture). The max
achievable range (but not guaranteed) is the following:
Tag types: BGCK-12 BGCK-70
Adjustable range From 1 to 15 m From 25 to 70 m
Note: the reading range is granted on the front part of the antenna using the BGCK-xx tag in a
perpendicular position on the respect of the transmission plan.

2.2 NETWORKING YOUR RFID SYSTEM
Wiegand controller (i.e. MWGD46)
2.3 OPERATING YOUR RFID SYSTEM
If – for example – your application is a Vehicle tracking management system, you may refer to the
following steps for the vehicle tracking.
1. Each car owners/drivers will be equipped with a 2.45 GHz active RFID tags: the tag IDs are
the globally unique ones, which associate the names and relevant information such as
vehicle type, user’s name, department, etc., into the server computer.
2. Since the power supply is +8V ~ +20V, please use an appropriate adaptor as a power source.
After following the right instruction in network connection of the 2.45 GHz RFID Readers
in a certain area, the readers automatically receive the information sending from the active
tags held by the car owner, then send the information to the Wiegand controller and wait for
the inquiry from the controller.
3. The server computer will combine the information read from the antennas and the
information from the active tag to operate the relevant devices such as raising the bar
automatically.
2.4 MANTAINING YOUR RFID SYSTEM
For a correct use of your RFID antenna, please, refer to the following tips.
1. Do not sabotage the 2.45 GHz active tag by beating or using strong impact on it.
2. Do not disassemble the tag by your own, other than for the battery replacement.
3. The 2.45 GHz tag can be fixed behind the windshield of the vehicle: in general do not fix
the tag in a dangerous position, such as close to the engine, etc.
4. Do not use the tag without its waterproof protection, since this prevent from moisture.
5. Do not remove the already fixed 2.45 GHz reader in a certain position unless it is
malfunctioned, otherwise the stability of the whole system will be affected.

2.5 TROUBLESHOOTING
In case of troubles while using your RFID antenna, please, refer to the following tips.
1. When the reader cannot read tags, please check the sequence of the yellow and the blue wire
for Wiegand port whether is wrong. If yes, please cut off the power supply and then swap
the yellow and blue wires for the correct connection.
2. When reading a tag, the reader’s Green LED is flashing but not the Red LED, and there is
no beep sound from the buzzer. Please connect the Green wire with the White wire together
so that the tag can be detected by the reader.
