Green LED activity indicates that there is an RF signal being received whose
hopping sequence corresponds to the configured hopping sequence of the
RF401. This does not necessarily mean that the network/radio address of the
received packet corresponds with that of the RF401 (where a neighbo u ring
network exists it is a good idea to choose a unique hopping sequence).
4.1.2 Radio Configuration
The RF401 and RF430 radios are designed to be easily installed, and for many
applications, the radios work out of the box using the default settings. RF401s
with operating systems of OS4 or higher and RF430s are configured for
PakBus networks. These radios have a Protocol setting of PakBus Aware and
an RS-232 Baud Rate of 38.4 K. RF401 radios with an operating system of
OS3 or lower have a Protocol setting of Transparent and an RS-232 baud rate
of 9600. The 9600 baud rate needs to be used if the network contains older
dataloggers (e.g., CR510, CR10X) or other devices that do not support the
38.4 K baud rate.
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 .
If the default settings need to be changed, our Device Configuration Utility
(DevConfig) is often the preferred method to use (see Section 5.1 , DevConfig
(p. 22)
). DevConfig provides the settings for the standard setup (see Appendix
B , Advanced Setup Menu
(p. B-1)
, for the advanced setup menu).
If the spread spectrum radios are used in a PakBus network, the radios may
also be configured using the Network Planner or PakBus Graph. The Network
Planner assists you in designing PakBus networks. Refer to Sections 5.2.2 ,
Network Planner
(p. 34)
, and 5.2.3 , PakBus Graph
(p. 35)
, for more information.
4.2 Power Supplies
Appendix L , RF401/RF411 Average Current Drain Calculations
(p. L-1)
, provides information about calculating current drain for
your system.
4.2.1 Base Radio Site (radio connected to a PC)
The USB port supplies power to the RF430. If an RF401 is used as a base
radio, the #15966 wall charger typically supplies 12 Vdc power to the radio.
The barrel connector of the wall charger connects to the radio’s Power jack.
