1. General

Radio Frequency Identification RFID is the acronym for radio frequency identification, commonly known as RFID. Radio Frequency Identification RFID is a non-touch automatic identification technology, radio frequency signal through the automatic target recognition and access to relevant data, to identify without human intervention, it can work in a variety of harsh environments. RFID technology can identify the high-speed moving objects, also identify multiple tags, the operation is quickly and conveniently.

Shenzhen eTel technologies co., ltd. according to market demand of the wireless internet of things RFID, Combine with FAM function, develop ET7430RFID Reader, it able to real time send RFID TAG information via the local network to data center. Data center platform will receive the data and save into database, users can just use browser to access data and view all information.

ET7430 RFID Reader is mainly used in schools, residential security, plant access, government access control, automotive systems, ET7430 RFID Reader also support FAM feature, which supports 3 DI, 1 DO, 1 AI, 2 TE ports, it can be connected to different sensors to cooperate with RFID function.

Active RFID supports two kinds of frequency, the following introduce the 433Mhz and 2.45Ghz RFID difference in practical application:





UHF 433Mhz

SHF 2.45Ghz

Reading Distance

0-100 meter adjustable

0-200 meter adjustable




Anti-collision performance



Recognition speed

Diffraction ability



2. Feature

·           Industrial Design

ET7430 RFID Reader is industrial design which built-in watchdog chipset to ensure the system work continuously, Watchdog monitoring the system all the time, if system does not response for long time, Reader will restart automatically. Reader is very suitable for long-term continuous work applications.

·           Basic TCP/IP network data transmission

RFID Reader supports Ethernet port, just a simple configuration, reader can quickly through user’s IP network to connect data center.

·           RFID card reader/writer distance adjustable, RSSI Location

Reader built-in signal attenuation, adjustable read/write distance cards, combined with RSSI function, the reading distance can be controlled to within 3 meter, and support locating position.

·           Main and backup data center

ET7430 RFID Reader support main and backup data center, user can set both main data center IP address or domain name, when Reader fail to connect with main data center, it will try to connect backup data center automatically.

·           TAG buffer

ET7430 RFID Reader can save the TAG card information in the NVRAM buffer, if the local network is abnormal, the reader will save data in the NVRAM, when the network returns to normal, the data will be sent immediately. NVRAM has feature for save data even power lose, so even reader power lose, Tag data will still save in the NVRAM. Reader buffer can save max 5000 TAG information.

·           TAG Packet Series Number

All TAG data packet include serial number, Data center need to reply a corresponding serial number of the ACK packet after received TAG packet, readers receive the ACK packet, then delete the TAG information from the buffer, otherwise it will resend TAG packet (as specified time interval and frequency). This feature is based on the IP network feature, to ensure TAG data doesn't lose.

·           Embedded Li-battery and Temperature sensor

ET7430 RFID Reader built-in 1000mA Lithium battery, it can work for 3 hours if the external power supply cut off. The built-in temperature sensor can real-time monitoring of environment temperature and the outside TE port can be extended to the user device surface to monitoring equipment temperature.

·           DO port programmable output

RFID Reader DO (digital output) port supports programmable output, according to the requirement of user site, the level of output level, switching time, times would be programmable.

·           Zone type

DI ports support zone type setting which can be set to as common zone, delay zone, intelligent zone, emergency zone, home zone, according to the user site conditions and sensor type, set the correct zone type to prevent false alarm, missing alarm.

·           RFID TAG, Keypad password, Fingerprint Authentication, Timing Arm/Disarm

Reader support multiple Arm/Disarm function, it can perform a specified time every day to Arm/Disarm; RFID TAG way to Arm/Disarm; Fingerprint authentication to Arm/disarm.

·           Micro SD slot (TF Slot)

Reader provide Micro SD Slot (slot TF slot) that is used to store camera photo/alarm log/arm disarm log and RFID TAG data. it can be sending TAG data to the data center, while stored in the TF card.

·           LED indicator to display Arm and Disarm

Reader DO port can be connected to 12V dual color LED lights, and displays the current Arm and Disarm status. Red indicates the FAM is ARM status, Green indicates FAM is Disarm status.

·           TAG link to DO output

Reader support TAG link to DO port output function, with the DO programming output function, we can connect a LED and buzzer on DO port, and then we would know TAG result according to the LED light and buzzer.

·           Clock synchronization

RFID Reader support clock synchronization; it can read the clock from management platform by IP network.

·           Graphical configuration software

ET7430 RFID Reader provides full graphical software configuration, easy to use, and supports import or export configuration file; so users just simply click a few icons to quickly setup RFID system.
