Program interface is shown below:
[/vc_column_text][vc_tour][vc_tab title=”Connection between PC and RFID Reader” tab_id=”1393277476-1-71″][vc_column_text]1.1 Serial Port Configuration
First select the correct serial port that is connected to the RFID reader. In the following example, we use COM3.
1.2 Connection between PC and RFID Reader
Press “Connecting” button. If you see the following message, PC has built a successful communication connection with the RFID reader.
If you see the following error message, the connection is failed. You need double check the serial port connection and RFID reader functionality.
When the connection between PC and RFID reader is built successfully, we can configure the RFID reader and demonstrate its functions.

- Press “Read Para” button, current parameter settings of RFID reader are read out and displayed on the GUI.
- Select proper parameter settings on the GUI, and press “Write Para” button, the selected setting will be written into RFID reader.
2.2 Basic Setting
- Command: RFID reader responses to commands it receives. For example, if it receives a command of reading tag, it will read a tag and send tag ID back to PC’s serial port. Refer to “Manual of SDK for LinkSprite UHF ISO18000-6B，ISO18000-6C(EPC GEN2）Far Distance RFID Reader” for command details.
- Timing Read: RFID Reader periodically read tags and output tag ids according to the selected Read Interval and Output Mode. For example, if Read Interval is set to 5ms, and Output Mode is set to RS232, then the RFID reader will read tags every 5ms, and send tag ids to RS232.
- Trigger Read: RFID reader reads tags and sends tag ids only when receiving a trigger signal.
Read Interval: Length of Interval (ms) between reading tags for Timing Read mode. Note: Read interval should be larger than 5ms in normal cases, since too small read intervals could shorten the lifetime of RFID reader.
Output Mode: Connection mode between PC and RFID reader.
- Wiegand 26
- Wiegand 34
Trigger: Types of trigger signals:
- Low level signal
- High level signa
2.3 Wiegand Setting
These settings only take effect only when Output Mode is set to Wiegand26/34. Please refer to Wiegand communication protocol for details. Note: Users usually only need to choose Byte Offset, and use default settings for other parameters.
2.4 Other setting
- Card Type: Selection of RFID tag communication protocol. Linksprite RFID reader support two protocols: 18000-6B and EPC (GEN 2).
- Power Setting: Set transmitting power of RFID reader. Maximum number is 18.
- Antenna Setting: Used when setting multi-channel. Select 2 for dual-channel and 4 for four-channel.
- Same ID Output Interval: Same ID Discrimination is used to reduce the redundancy of RFID reader’s uploaded data. By using this function, when the RFID reader repeatedly reads a tag within a given interval, it only uploads one set of data. If the interval time between two adjacent readings of a same tag is larger than the parameter “Same ID Output Interval”, the Same ID Discrimination doesn’t take effect.
- Frequency: These parameters are related to 18000-6B and EPC (GEN 2) protocols. Usually set to Hopping-Freq.
- Buzzer: Turn on/off the beeping when recognizing an RFID tag.
- 18000-6B Identifying: Searching RFID tags in working range, and reading their 8-byte UIDs.
- 18000-6B Reading: Searching RFID tags in working range, and reading data that starts from the designated “Address” and with the designated data “Length”.
- 18000-6B Writing: Writing the designated “Data” into RFID tag, starting from the designated “Address” and with the designated data “Length”
- EPC(GEN2) Identifying: Searching RFID tags in working range, and reading their EPCs.
- EPC(GEN2) Reading: Searching RFID tags in working range, and reading data from the designated “MemBank” that starts from the designated “Address” and with the designated data “Length”.
- EPC(GEN2) Writing: Writing the designated “Data” into the designated “MemBank” of RFID tag, starting from the designated “Address” and with the designated data “Length”
- EPC is stored in 16-Bit format, so it’s read/written in 2-Byte increment. And 18000-6B is stored in 8-Bit format, so it’s read/written in 1-Byte increment.
- When reading data from “EPC Block”, the data length should be no longer than 64.
- When writing data to “EPC Block”, the data length should be no longer than 64, and the writing address starts from 2.
- For “18000-6B Demo” and “EPC (GEN2) Demo – Single”, the “Command” working mode show best demonstration performance, so when you enter the two demo windows, there is a reminder message as follows.
- This Demo is for the applications that need simultaneously read multiple RFID tags.
- The multiple-tag Demo works in “Timing Read” mode or “Trigger Read” Mode.
- The GUI displays the information of all RFID tags that are read and the number of reading times for each tag, as shown in the following figure.
- Press “Clear” to remove the current data.
[/vc_column_text][/vc_tab][vc_tab title=”Write Card Demo” tab_id=”1393279180845-5-3″][vc_column_text]This function is to write ID into DFID tags. You can select types of Wiegand protocols. We also provide a small tool to convert numbers between Hex format and Decimal format.
