Hop Channel Spacing
Controls the hop channel spacing when frequency hopping is enabled.
Parameter address: 0x0034
Length (bytes): 4
Default value: 0x00030D40 (200 KHz)
To enable frequency hopping, set a frequency range using the Start Frequency and Stop Frequency system
parameters. Then use the Frequency Hopping Sequence parameter to set the frequency hopping mode
(either sequential or pseudo-random). To disable frequency hopping, set the Start Frequency and Stop
Frequency parameter to the same value.

Frequency Hopping Sequence
Switches the hopping sequence between pseudo-random and sequential mode.
Parameter address: 0x0035
Length (bytes): 1
Default value: 0x01 (pseudo-random)
To set the reader to sequential hopping mode, write 0x00 to this parameter.
To reset the reader to pseudo-random hopping sequence, write 0x01 to this parameter.
To enable frequency hopping, set a frequency range using the Start Frequency and Stop Frequency system
parameters. Then use the Frequency Hopping Sequence parameter to set the frequency hopping mode
(either sequential or pseudo-random). To disable frequency hopping, set the Start Frequency and Stop
Frequency parameter to the same value.
