Description
4.1.9 RFCHAN: RF Channel Select
4.1.10 ATTEN: Transmit Power Attenuation
RFCHAN {chan}
Define RF channel
None
This command sets the reader’s RF frequency channel to 1 of 50 available channels between 902-
928Mhz. The channel spacing is 500kHz with the first RF channel starting at 902.5MHz.
ATTEN {val}
Transmit RF attenuation – AS3992.
None
This command applies additional attenuation to the transmit output power. At startup, 10dB of
attenuation is applied to the AS3992 output. The transmitted output power is not a linear function –
it has the general output from shown in Figure 1 below. The AS3992 output may be attenuated from
0dB to 14dB. If maximum output power is desired, the attenuation must be set to 0.
Parameter
chan
Parameter
val
Value (hex)
1 – 32
Value (hex)
0-E
Definition
The channel identifier defines a channel number between 1 and 50.
The parameter passed in the instruction is presented as a hexadecimal
value.
Definition
The output attenuation is set through this parameter. The AS3992
output power attenuation defaults to 10dB, or val=xA (in
hexadecimal).
