Communications Time
TAT represents the total time from when a command is first sent from the host device until a response
is received. The transmission time represents the time required for communications between the
Hand-held Reader Writer and the ID Tag, not including communications with the host device.

 V680-CH1D TAT
 V680-CHUD TAT
Note 1) In V680 mode, communications specifications for TAT data with the host device represent values with a baud rate of
9,600 bps, a bit length of 8 bits, 1 stop bit, and even parity. In this example, characters are sent consecutively, with no
spaces between them.
2) The number of bytes in the TAT data is the number for hexadecimal encoding.
