Communications Time
Communications time differs according to the type of Data Carrier memory (SRAM or EEPROM). TAT
(Turn Around Time) and transmission time are displayed as communication times. 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 Data Carrier, not including communications with the host device.
