Various frequency bands formula:
User band:
Fs = 902.6 + N * 0.4 (MHz), N
∈
[0, 62].
Chinese band2:
Fs = 920.125 + N * 0.25 (MHz), N
∈
[0, 19].
US band:
Fs = 902.75 + N * 0.5 (MHz), N
∈
[0, 49].
Korean band:
Fs = 917.1 + N * 0.2 (MHz), N
∈
[0, 31].
8.4.3 Set Address
The host sends this command to change the address (
Adr
) of the reader. The address data is stored in the
reader’s inner EEPROM and is nonvolatile after reader powered off. The default value of
Adr
is 0x00. The range
of
Adr
is 0x00~0xFE. When the host tries to write 0xFF to
Adr
, the reader will set the value to 0x00
automatically.

8.4.4 Set Scan Time
The host sends this command to change the value of InventoryScanTime of the reader. The value is stored in
the reader’s inner EEPROM and is nonvolatile after reader powered off.

Scantime:
Inventory Scan Time. The default value is 0x0A (corresponding to 10*100ms=1s). The value
range is 0x03~0xFF (corresponding to 3*100ms~255*100ms). When the host tries to set value 0x00~0x02 to
InventoryScanTime, the reader will set it to 0x0A automatically. In various environments, the actual inventory
scan time may be 0~75ms longer than the InventoryScanTime defined.
