TAT When Using an ID Controller (Reference Values)
TAT (Turn Around Time)
TAT refers to the total time required from the point at which a host device (such as a personal computer) starts sending a command until a
response is received.
1-kbyte Memory ID Tag
V680-D1KP@ (used in combination with the V680-HS@@ Read/Write Antenna and V680-HA63A Amplifier Unit)
V680-D1KP58HT (used in combination with the V680-H01 Read/Write Antenna)
Note 1. These are the TAT values for a baud rate of 115,200 bps. For information on the TAT for baud rates other than 115,200 bps, refer to the
Command send time:
ID Tag transmission time: This is the time required for transmission between the Read/Write
Response receipt time:
Normal mode
High-speed mode
(See notes 2 and 3.)
Controller or ID Sensor
TAT = Command send time + ID Tag transmission time + response receipt time
Unit transmission
2. The V680-H01 Read/Write Antenna cannot be used in high-speed mode.
3. When multi-access or FIFO is selected as the transmission option, the transmission time will be the same as in normal mode even when
4. The value given for TAT data assumes that communications settings for the V680-CA5D01/02-V2 ID Controller are as follows:
5. The number of bytes of TAT data is the number of bytes when ASCII is specified as the code.

the transmission speed is set to high-speed mode.
Data length: 8 bits, Stop bits: 1, Parity: Odd.
In this example, communications are continuous, with no gaps between characters.
This is the time required for sending a command from the host
device to the Controller.
It varies depending on the communications speed and format.
Antenna and the ID Tag.
This is the time required for returning a response from the
Controller to the host device.
It varies depending on the communications speed and format.
