6) to read the fingerprint template index table ReadConList
Description: Read module fingerprint template index table, and each index table to read up to 256 fingerprint templates.
Input parameters: index page
Representative of the index page 0 read 0 to 255 fingerprint template index table
Index page represents read 256 to 511 fingerprint template index table
2 represents the index page reads 512 to 767 fingerprint template index table
3 representatives of the index page reads 768 to 1,024 fingerprint templates index table
Return parameters: Recognition word the + fingerprint template index table

command packet checksum (2 bytes) = packet identification (1 byte) + packet length (2 bytes) + script (1 byte) + (1 byte) index page;
response packet checksum (2 bytes) = packet marking (1 byte) + packet length (2 bytes) + confirmation code (1 byte) + index table (N bytes);
checksum bytes added to carry more than 2 bytes ignored, big endian transfer;
default module address "0xffffffff"; default password is "0x00000000".
