RF407-Series Spread Spectrum Radio

11.1.6 Network ID
Specifies the RF network. This setting must match in all radios in the same RF
network. Valid entries are 0 to 32767.
11.1.7 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 @12V Description
Always on < 12 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.
0.5 Second < 2 mA
The radio receiver is turned on every 0.5
seconds for 100 milliseconds to look for RF
activity. The radio transmits a 700
millisecond wakeup header with the first
transmission occurring after a period of RF
inactivity. This is one of the most common
setting in networks that do not contain
CR200(X)-series dataloggers.
1 Second < 1 mA
The radio receiver is turned on every 1
second for 100 milliseconds to look for RF
activity. The radio transmits a 1.2 second
wakeup header with the first transmission
occurring after a period of RF inactivity.
This is one of the most common setting in
networks that contain CR200(X)-series
dataloggers.
4 Second < 0.6 mA
The radio receiver is turned on every 4
seconds for 100 milliseconds to look for RF
activity. The radio transmits an 4.2 second
wakeup header with the first transmission
occurring after a period of RF inactivity.
Only use this setting in networks where time
between communications is long (hours) and
saving on average an additional 1 to 1.5 mA
is essential.
11.1.8 Retry Level
An advantage of using one of the PakBus
®
protocol modes is that the radios
will retry packet delivery at the RF level. This setting specifies the level to
which the radio should retry to deliver an unacknowledged RF packet
