  4. Set_Reader_Config • It carries 2 parameters • RF transmitter Parameter • Inventory and Access Reporting Parameter RFU Ver=0x1 Type=0x2 Length=0x17 Message Seq Num = 0x2782 RFU 00 RFU S=1 Type=0x12 Length=0x8 RF Transmitter Parameter AntId=1 TXPower = 0xFF FhSeqId = 0 RFU 00 RFU Type=0xA1 Length=0x8 Inventory and Access Report Parameter Trigger=0x1 Contents=0x1 RFU Contents = 0x1 = Send only tag list Trigger = 0x1 = Send Inventory report after every inventory round

  5. Inventory Command • It carries 2 parameters • Inventory Operation Timing Parameter • EPC C1G2 Singulation Parameter RFU Ver=0x1 Type=0x10 Length=0x2B Message Seq Num = 0x2786 RFU AntId=1 RFU Air Protocol =0x4 (C1G2) 00 L=0 RFU Type=0x23 Length=0x20 00 N=1 RFU Type=0x14 Length=0x10 Inventory Operation timing Parameter C1G2 Inventory Command Parameter Start Time =0 (ignore) Start now Start Round = 0 End Round = 1 Round Size = 0 (ignore) 00 RFU Type=0x21 Length=0xC C1G2 Singulation Parameter RFU Sess=3 I=0 S=0 M=0 Mob = pop = env = ignore Q = 10 Qstepupsize = Qstepdownsize = ignore Tags in A state Tags in SL=1 state

  6. Inventory and Access Report RFU Ver=0x1 Type=0x20 Length=0x47 • It carries a list of tag parameters • Tag data Parameter (0xA4) Message Seq Num = 0 RFU 00 RFU Type=0xA4 Length=0x14 Timestamp = T1 RSSI = R1 RFU Tag Data Parameter Tag 1[0:31] Tag 1[32:63] 00 RFU Type=0xA4 Length=0x14 Timestamp = T2 RSSI = R2 RFU In this example, 3 tags are seen by the reader; 2 64 bit tags, 1 96 bit tag. Tag 2[0:31] Tag 2[32:63] 00 RFU Type=0xA4 Length=0x18 Timestamp = T3 RSSI = R3 RFU Tag 3[0:31] Tag 3[32:63] Tag 3[64:95]
