    33In 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].

    5 To 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:

    4343This 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 [https://69.164.214.41/projects/fslapcounter/wiki/S6350serialcom#Collisions collisions] [https://209.20.66.101/projects/fslapcounter/wiki/S6350serialcom#SilenceTag silence] the tag after it is detected.

     45This command is used to detect RFID's during a race.  The response time to this command is approximately 2ms giving us sufficient accuracy for tracking RFID's.
