Industrial automation RFID high-frequency reader/writer head CK-FR03-A01 is a high-frequency RFID tag reader based on radio frequency identification technology. The working frequency of the reader is 13.56MHZ. It supports I-CODE 2, I- CODE SLI, etc. conform to the ISO15693 international standard protocol format label reading. The radio frequency part of the communication protocol is integrated inside the card reader. The user only needs to receive data through the RS485 communication interface to complete the reading operation of the tag without understanding the complex radio frequency communication protocol.
The card reader comes with an Auto-turning automatic tuning circuit, which can automatically adjust the circuit parameters when working in different environments to minimize the influence of the external environment on the reading distance, further enhance its own anti-interference ability, and have high receiving sensitivity , Stable performance, strong reliability and other characteristics.
The card reader can be widely used in logistics, warehouse management, process control, robotic arm site control and other fields.
The reader mode is as follows:
| Card reader mode |
Register value (H) |
| Standard MODBUS |
0001 |
| Continue Read Mode |
0003 |
| Read Once Mode |
0004 |
| Standard MODBUS |
FFFF |
| invalid |
Other value |
The setting process of card reader modes such as Continue Read Mode and Read Once Mode is as follows:
Example:
| operating |
send command |
| Query card reader configuration |
02 03 00 00 00 06 C5 FB |
| Modify the card reading mode (such as Continue Read Mode） |
02 06 00 03 00 03 39 F8
|
| Set the head and end of the frame (here, set the pillow to AA, and the frame end to BB) |
02 79 01 01 AA BB F2 DC |
| Specify the read data (here, the specified read address is 0x0006, and the number of read registers is 4) |
