Pin 1: Tag communication speed
Pin 1 is used to set the speed of communications with Tags. When this pin is
set to Standard Mode, a longer communications distance can be used, but
communications will be slower. When this pin is set to Fast Mode, the
communications distance with Tags will be reduced, but communications will
be faster. Use the best mode for your application.
Note Although both modes can be used with the V720-H01-E Read Write
Antenna, if large Antennas are added to the series in the future, there may
be cases where Fast Mode cannot be used in Japan because of laws
regarding electromagnetic waves. For details, refer to the documentation on
the Read Write Antenna actually used.

Pin 7: RS-485 Terminating Resistance (V720-CD2D)
To ensure stable operation when using more than one Controller with one
host device, the RS-485 communications line must be terminated with a
terminating resistance at the Controllers at both ends of the line or at the
Controller at one end and the host device.
Pin 7 is used to enable or disable the built-in RS-485 terminating resistance.
