TAT (Turn Around Time)
• The TAT depends on the type of Data Carrier being used (with or without a built-in battery).
• The TAT of Data Carriers without batteries also depends on the communications mode setting.
• The TAT is the total time required for the host device to receive a response after it has finished send-
ing a command.
Command send
time
: The time required to send a command from the host device to the ID Controller.
The command send time depends on the baud rate and communications
format.
Data Carrier
communications
time
: The time required for communications processing between the Read/Write
Head and Data Carrier. Refer to the next page to find the values.
Response reception
time
: The time required to return a response to the host device from the ID
Controller. The command send time depends on the baud rate and
communications format.
TAT = Command send time + Data Carrier communications time + Response reception time
