RF401A-Series Spread Spectrum Radio

11.1.5 RF Hop Sequence
Specifies the radio channel hop sequence. This setting must match in all radios
in the same RF network. This setting can also be used to prevent radios in one
RF network from listening to transmissions of another.
11.1.6 RF Network
Specifies the RF network. This setting must match in all radios in the same RF
network. Valid entries are 0 to 3 for radios with Protocol set to PakBus Aware
or PakBus Node. Valid entries are 0 to 63 for radios with Protocol set to
Transparent.
11.1.7 RF Radio Address
Specifies the radio address. The radio address is only used when Protocol is set
as Transparent. Radios must have matching radio addresses in order to
communicate. Valid addresses are 0 to 1023.
11.1.8 Power Mode
Power Mode governs the duty cycle that the radio will use for powering its
receiver. As such, it governs the amortized current drain for the radio. Note that
choosing a low power mode that requires a long transmission header for a
network with frequent communications can actually cause a higher average
power draw; a large percentage of the communication interval is spent in high
power transmission.

Current
Draw Description
Always
on, No
Header
< 15 mA
The radio receiver is always on. Additional wakeup
header is never transmitted. Use this setting in a network
with very frequent communications or when network
latency needs to be minimized. The red LED is always
on.
Always
on, 1 Sec
Header
< 15 mA
The radio receiver is always on. A wakeup header of 1.2
seconds is transmitted at the beginning of the first
transmission occurring after a period of RF inactivity to
ensure that other radios in the network set to a 1 second
mode are awake and ready to communicate. Using this
setting is uncommon, generally only used in a base radio
that communicates with a CR200-series datalogger
configured with a power mode of “1 second” (no
header). The red LED is always on.
Always
on, 8 Sec
Header
< 15 mA
The radio receiver is always on. A wakeup header of 8.2
seconds is transmitted at the beginning of the first
transmission occurring after a period of RF inactivity to
ensure that other radios in the network set to an 8 second
mode are awake and ready to communicate. Using this
setting is uncommon, generally only used in a base radio
that communicates with a CR200-series datalogger
configured with a power mode of “8 second” (no
header). The red LED is always on.
