：・ The provided TAT graph data shows an example in which the V720S-BC5D4A Controller is used with the

following communications specifications for host communications: Data is continuously sent with no

space between characters, at a baud rate of 38,400 bps, in a data length of 7 bits with 1 start bit, 2 stop

bits and even parity . The number of bytes in case ASCII are specified as the data code.

・The transmission rate of the Tag is set in Fast Mode as factory default.

（2）Communication time in

Multiple modes:

The communication time when the commands with multiple access options

are used varies depending on operating conditions. Those conditions

include the number of bytes, as well as the number of Tags in the

communication area. The mean values in consideration of these conditions

are shown in the table below.

Example of Multiple Access communication time: I.CODE1 Chip (msec)
