Ethernet Uart UHF RFID Reader 860~960MHz ISO18000-6C 1-15m


Introduction and Application

UHF RFID card reader is an important way of information datas automatic identifying and inputing,it is a comprehensive technology base on computer and communication technology.The automatic identification technology develop quickly in rescent years,which consist of barcode technology,magstripe technology,RF technology,optical character identification technology,biometrics identification technology and UHF RFID reader etc.
Usually,UHF RFID reader has high sensivity.In some system,receiving and transmitting of UHF RFID reader is mutually independent,especially when uplink signal frequency is different from downgoing signal.
Generally,transmitting power 100mW-500mW is applicable to all kinds of UHF RFID reader.
E_RFID915M_0703 UHF RFID reader has many advantages of more protocol supporting,fast reading,more lables identification,circular polarization antenna and compact design. This reader is widely used in all kinds of RFID system.

Using Explanation:
The UHF RFID reader start to work when the buzzer makes a sound,when the tag approach the reader,the buzzer makes a sound again to indicate transmitting datas.The time interval which between two times of reading one IC card is set by software.After read card, the IC card will not make any indication and not transmit datas if it is still in RFID reader field,but if exceed the time interval,or other ID cards in RFID reader filed, the reader will read cards and transmit datas.
The UHF RFID reader use radio influence technology,avoid to approach the metal as far as possible when using it.The radio wave will be affected by metal and reading distance will be shorted when reader approach to metal.The UHF RFID reader installation position should be far away from motor and transformer etc, to reduce the impact on reader.
E_RFID915M_0703 reader support E_RFID915M_0211 and E_RFID915M_0311, compatible with Wiegand 26 bits/Wiegand 34 bits/RS485.
E_RFID915M_0703 reader is mainly used in Parking lot .
E_RFID915M_0703 reader provide SDK with demo of VB and VC.

Hardware Installation and Application
1) Installation
There are two way to install the reader bracket: “1 type” and “L type”, see pictures below: select the installation way according to application and actual system. Generally, “1 type” reading distance is not long, but simple installation; “L type” reading distance is longer, but complicated installation.
2) Reader Fixing and Height Adjustment
“1 type”, the diameter of bracket pole must be 50-60mm, the length is 2.2 meter, and it would be better use the stainless steel material which thickness is more than 1.2mm.Fix the reader at the top of bracket by accessories. Adjust the height of reader according to car type (big car or small car); usually the height is about 2.0m (1.8-2.2 meter).
“L type”, the diameter of L type bracket vertical pole must be 60-80mm, the diameter of horizontal pole must be 50-60mm, and it would be better use the stainless steel material which thickness is more than 1.2-2.0mm. Fix the reader at the top of bracket and close to the center of roadway. Adjust the horizontal pole height according to car height; usually the height is about 3.5-4.0meter.
3) Reader Angle Adjustment
Angle picture
Antenna angle 1:when antenna incline ground, the angle between antenna and horizontal line, is about 60~75
Antenna angle 2:when antenna incline roadway, the angle is about 30~40°
1) RS-232
2) RS-485
3) Wiegand
Attention and After Service
1) When card reader working, the installation people should stand 30cm away from the antenna, this is the most approaching distance of America FCC standard.
2) Stand far away from reader when it working.
3) Wiegand communication, power trigger level should be same as Wiegand trigger level.
4) Trigger conditions: high level or low level.
5) According to production date, we provide 1 year guarantee, but collision, high voltage, wrong operation and man-made damage are not in free repairing field.
