RFID Module Specification-時序圖 • 資料傳送至RF-201 DATA腳與CLOCK腳的時間單位 Low Bit High Bit Data Clock 50 us Note : 在 Low to High 時讀取資料 • 資料接收時序同上圖, 等待讀取時的Time Out (30 ms)

RFID Module Specification-資料格式 • Length ；資料長度, 此為 Command 1 至 [Data] 的 Bytes 數 • Command 1 • Bit 3 0 UID 不使用 1 UID 使用 Bit 5 0 0 1 1 Bit 4 0 Read System Information 1 Read Block 0 Write Block 1 Lock Block

RFID Module Specification-資料格式 • Data a. Read Data = 不使用 b. Write Data = 4 Bytes data (由 Low Byte 先送) • BCC a. 為各 Byte 資料加總 b. BCC = Length + Command 1 + Command 2 + [UID 1 + UID 2 ……. . + UID 8] +[Block] + [data 1 + data 2 + data 3 + data 4]

RFID Module Specification-功能列表 • • Read System Information Read Block Write Block Lock Block

RFID Module Specification-功能列表 • Read System Information • • • Length = 00000010 B Command 1 = 0000 B Command 2 = 00100000 • • • Length = 0001 B Command 1 = 00001000 B Command 2 = 00100000 B System Information A. Flags = 1 Byte B. Information Flags = 1 Byt C. UID = 8 Bytes D. DSFIO = 1 Byte E. AFI = 1 Byte F. Other = 3 Bytes

RFID Module Specification-功能列表 • Read Block • • Length = 00000011 B Command 1 = 00010000 B Command 2 = 00100000 B Block = 0 – 63 (DEC) • Length = 00001000 B • Command 1 = 00010000 B • Command 2 = 00100000 B Flags = 1 Byte Security = 1 Byte ( 0 未 Lock, 1 Lock ) Data = 4 Bytes Data

RFID Module Specification-功能列表 • Write Block • • Length = 00000111 B UID = 8 Bytes Command 1 = 00100000 B Block = 0 – 63 (DEC) Command 2 = 00100000 B Data = 4 Bytes Data 注意 : 寫入時請由 Low Bytes 先送 • Length = 00001000 B • Command 1 = 00100000 B • Command 2 = 00100000 B Flags = 1 Byte Security = 1 Byte ( 0 未 Lock, 1 Lock ) Data = 4 Bytes Data

RFID Module Specification-功能列表 • Lock Block • • Length = 00000011 B Command 1 = 00110000 B Command 2 = 00100000 B Block = 0 – 63 (DEC) • Length = 00001000 B • Command 1 = 00110000 B • Command 2 = 00100000 B Flags = 1 Byte Security = 1 Byte ( 0 未 Lock, 1 Lock ) Data = 4 Bytes Data
