APPENDIX 1 COMMUNICATION TIME (REFERENCE)
The following describes the communication time between the RFID interface module
and ID tag, according to ID tag type.
For suitable ID tag and antenna combinations, refer to the Omron RFID system V680
series manual.

communication specification area (Un
\
G1, Un
\
G4001), the communication time
becomes the standard mode communication time, even if the ID tag communication
speed setting is high-speed mode.
