This does an inventory of just the first time slot, which allows for a faster inventory responses but can not handle collisions. A collision is when two tags or more tags are in the field at the same time. To minimize collisions silence the tag after it is detected. 38 38 39 39 {{{ 40 40 Byte 1 is the Start of Frame, always 01 41 41 Byte 2 and 3 is the length of the command including the 2 byte check sum that is added to the end, Least Significant Byte first … … 51 51 The resulting command could look like this: 52 52 ChrB(&h01) + ChrB(&h0D) + ChrB(&h00) + ChrB(&h00) + ChrB(&h00) + ChrB(&h00) + ChrB(&h60) + ChrB(&h11) + ChrB(&h27) + ChrB(&h01) + ChrB(&h00) + ChrB(&h5B) + ChrB(&hA4) 53 54 55 56 57 58 59 60 61 53 }}} 62 54 63 55 = Silence Tag = … … 65 57 The UID passed must be a string in the reverse byte order that it is recieved in the string assemled by this can be sent directly to the serial port to silence the given RFID tag 66 58 67 dim silencecommand as string 68 59 {{{ 69 60 Everything but checksum, portion before UID is the ISO15693 silence command for a TI S6350 70 61 Byte 1 is the Start of Frame, always 01 … … 82 73 83 74 ChrB(&h01) + ChrB(&h14) + ChrB(&h00) + ChrB(&h00) + ChrB(&h00) + ChrB(&h00) + ChrB(&h60) + ChrB(&h11) + ChrB(&h23) + ChrB(&h02) + UID + Checksum 84 75 }}} 85 76 86 77 = Checksum =
