    3 In order to use the [wiki:S6350 TI reader] within RealBasic we had to implement some of the serial protocol ourselves.  You must first generate a command encapsulated in the TI protocol and have the payload of the command be the [wiki:ISO15693] command.  Only 3 of the [wiki:ISO15693] commands are necessary to track RFID's, [https://69.164.214.41/projects/fslapcounter/wiki/S6350serialcom#InventoryAllSlots Inventory All Slots], [https://209.20.66.101/projects/fslapcounter/wiki/S6350serialcom#Inventory1slot Inventory 1 Slot] and [https://209.20.66.101/projects/fslapcounter/wiki/S6350serialcom#SilenceTag Silence Tag].

    55To use [wiki:ISO15693] commands with the TI reader the command must be encapsulated in a TI command followed by a [https://69.164.214.41/projects/fslapcounter/wiki/S6350serialcom#Checksum checksum].  An example of the TI command structure follows: 
    … …  
    2626= Inventory All Slots = 
    2727 
    28 This sends an ISO15693 inventory command for the TI S6350 reader.  It does an inventory of all time slots, this supports anti-collision but is too slow to use during a race as it takes about .3 seconds to return results.  This command is used to scan in racers before a race starts.  By using the inventory all slots command everyone can line up on the finish line and one inventory done to add them to the race.

    51 This sends an ISO15693 inventory command for the TI S6350 reader. 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 [https://69.164.214.41/projects/fslapcounter/wiki/S6350serialcom#SilenceTag silence] the tag after it is detected.
