In order to communicate with this RFID reader you must set your serial device to 38400 baud, 8 data bits, 1 stop bit, no parity.  This reader is using the [wiki:ISO15693] protocol like the [wiki:S6350 TI reader].  Though the protocol is the same the commands used to execute the protocol are different.  The Kyosho IC lap counter also supports a [wiki:KyoshoICserialcom#AutomaticPollingMode automatic polling mode] that the TI reader does not support.

-Collision information here!!!!
+The Kyosho IC lap counter does not appear to be using any collision detection.  When using the [wiki:KyoshoICserialcom#AutomaticPollingMode automatic polling mode] the reader would only return at most 1 tag if multiple tags were in the field at the same time.  Sometimes it would not return any results.
