The GR-250 High Performance Reader has additional capabilities that are implemented using this software via the RS-232 interface.  Up to 3,072 transponder ID number readings, automatically stamped with date & time, can be stored in memory into one or more of 254 separate groups, called lots.  In addition to saving transponder readings that can be uploaded to a computer, the GR-250 High Performance Reader can search for transponder numbers previously stored in one of the 254 lots.  When a match is found, an audible tone is emitted, and the LCD displays a “match” message.  The transponder ID number just “matched” can optionally be stored into a keylot for subsequent uploading to a computer via the RS-232 interface.
