5.1.2.1 Active Interface
The only Active Interface settings that are available for the
RF430 radios are Auto Sense and RS-232. When changing
the RF430 active interface, it is necessary to cycle power to
the RF430 for the change to take effect.
The factory default setting for Active Interface is “Auto Sense.” It is designed
to automatically configure the radio’s port for common user situations. For the
RF401, Auto Sense determines whether or not a datalogger (or PS100 with an
A100 adapter) is connected to the radio by looking for 5 V on the CS I/O pin 1.
If 5 V is present, Auto Sense selects the RF401’s CS I/O port. Not finding 5 V
on CS I/O pin 1, Auto Sense selects the RS-232 port. For the RF430,
AutoSense looks for activity on the USB port. If activity is present, AutoSense
selects the USB port.
If powering an RF401 from the CS I/O port but communicating via the RS-232
port, the RS-232 setting needs to be chosen. The RS-232 setting can also be
chosen if the radio is connected to a datalogger’s RS-232 port.
The Datalogger SDC and Datalogger Modem Enable settings are used when an
RF401 is connected to the datalogger’s CS I/O port. Choose the SDC setting if
the RF401 is connected to a PakBus datalogger (CR800, CR850, CR1000,
CR3000). Choose ME if the RF401 is connected to a mixed-array datalogger
(CR510, CR10(X), CR23X).
The ME Master setting should be chosen if a COM200-series phone modem or
another ME configured device is connected to a base RF401’s CS I/O port.
The baud rate of both the COM200-series modem (or other device) and the
RF401 radio must be the same (see Section 5.1.2.5 ,
CS I/O ME Baud Rate
(p.
26)
).
PakBus Router should be chosen if the radio will be used as a standalone RF
router (repeater). When this is chosen, the Protocol should be set to PakBus
Node (see Section 5.1.2.3 , Protocol
(p. 24)
).
5.1.2.2 SDC Address or CSDC Address
This parameter is called SDC Address for RF401 radios with OS4 or higher
and RF430 radios. It’s called CSDC Address for RF401 radios with OS3 or
lower. The parameter is used when the radio is connected to a PakBus
datalogger (e.g., CR200(X), CR800, CR850, CR1000, or CR3000). Valid
settings are 7, 8, 10, or 11; the default is 7.
5.1.2.3 Protocol
The protocol choices are Transparent, PakBus Aware, and PakBus Node. The
default setting is PakBus Aware (RF401s with OS4 or higher or RF430s) or
Transparent (RF401s with OS3 or lower). The Transparent setting must be
chosen if the network contains the retired CR205 dataloggers or the retired
RF400 radios. When the Transparent protocol is used, all CR206(X)
dataloggers, RF401 radios, and RF430 radios must be set to Transparent.
The PakBus Aware and PakBus Node protocols are designed to work in
conjunction with PakBus to compensate for the interference and collision
problems inherent in RF networks. These protocols accomplish this primarily
