Communication Time; Transmission Time; Tat - Omron V700 series Operation Manual

5.3 Communication Time

The Model V700 Series has two communication times: the transmission time and
the TAT (Turn Around Time).

(1) Transmission Time

This is the transmission processing time between the Reader Writer and the
Tags. This time varies in accordance with the number of pages to be read /
written.
The transmission time values are as indicated below. This value is estimated
based on the assumption that the transmission operation is on trigger mode
and that there is no interference in transmission due to noise and other
causes.

This is the time required for the high-end unit to transmit a command to the
Reader Writer, and to complete receipt of a response. This time varies in
accordance with the transmission speed and the communication control mode.
