RF401-series and RF430-series Spread Spectrum Radio/Modems
26
If the RF430’s operating system is prior to OS2, its USB port will
only communicate at 38.4 kbps. Therefore, the RF430 operating
system will need to be updated to a newer version if the network
will contain dataloggers that do not support 38.4 kbps. Operating
system updates are available from
www.campbellsci.com/downloads .
When the radio is connected to a PC, the baud rate selections in LoggerNet
Datalogger Support Software must agree with the baud rate setting for the
radio. In the "AutoSense" mode, if the RF401 is connected to a datalogger's
CS I/O port, the RS-232 Baud Rate is irrelevant since the RF401
communicates with the datalogger in the "SDC" mode.
5.1.2.5 CS I/O ME Baud Rate
5.1.2.6 Hop Sequence
This setting is only used if the active interface is set to Datalogger Modem
Enable or ME Master. The default value of 9600 is typically used if the active
interface setting is Datalogger Modem Enable. When the active interface is
ME Master, this baud rate must match the baud rate of the COM200-series
modem (or other device).
The hopping sequence must be the same for all radios in your network. The
default value of 0 is typically used, unless there are neighbo
u
ring RF401/
RF430 networks. Ideally, neighbo
u
ring radio networks use different hop
sequences to prevent interference. Valid entries are 0 to 6.
To determine if there is a neighbo
u
ring RF401/RF430 network
in operation using the same hopping sequence as yours,
stop communications on your network and observe the radio’s
green LED for activity. A flashing green LED indicates that
there is a nearby network using the same hopping sequence.
5.1.2.7 Net Address
Use the default net address of 0 unless a neighbo
u
ring RF401/RF430 network
is using this setting. All spread spectrum radios in your network must have the
same net address setting. Valid entries are 0 to 3 for radios set to "PakBus
Aware" or "PakBus Node"; valid entries are 0 to 63 for the "Transparent"
protocol. Refer to Appendix C ,
Address and Address Mask
(p. C-1)
, for more
information about the Net Address.
5.1.2.8 Radio Address
The radio address setting is only used when the radio’s protocol setting is
Transparent. For two radios to communicate, their radio addresses must be set
to the same number. The factory default radio address is “0” (zero); valid
addresses are 0 to 1023. For simple point-to-point installations, the radio’s
default settings should work unless there is a neighbo
u
ring network which uses
the default setting. Refer to Appendix C ,
Address and Address Mask
(p. C-1)
, for
more information about the Radio Address.
