RF401-series and RF430-series Spread Spectrum Radio/Modems
4.2.2 Remote Sites with Datalogger
At the remote site, an RF401 radio is usually powered by the datalogger through its
CS I/O port. Alternatively, the #14291 Field Cable can be used to connect the radio
to an appropriate 12 Vdc power supply. The 14291 Field Cable connects to the
radio’s Power jack.
The field cable is required for the following situations:
• RF401-series radio connected to the datalogger’s RS-232 port instead of
the CS I/O port
• RF430-series radio connected to the datalogger (RF430-series radios do
not have a CS I/O port)
• Datalogger purchased before December 1997 (see TABLE 3-2 in Section
3, Installation)
If ac power is available, the #15966 wall charger may also be used to power the
radio (see Section 4.2.1, Base Radio Site).
If powering the RF401 from the CS I/O port but communicating
via the RS-232 port, be sure to select RS-232 as the Active
Interface so that the CS I/O port is not automatically selected by
Auto Sense.
4.2.3 Non-datalogger Remote Site
Radio-to-MD485 networks and radio-to-phone networks require a power
supply with a null modem port at the non-datalogger site. An A100 adapter
used with a PS100 power supply provides this capability. The PS100 is
recharged via a wall charger or a solar panel.
4.3 Serial and USB Cables
An RF401 base station must use the included 10873 RS-232 cable to connect
the RF401’s RS-232 port to the PC COM port. An RF430 base station
normally uses the included USB cable to connect the RF430’s USB port to the
PC’s USB port. An RF430 base station can also be connected to the PC COM
port via the 10873 RS-232 cable.
A remote RF401 normally uses the included SC12 cable to connect the
RF401’s CS I/O port to the datalogger’s CS I/O port. A remote RF401 can
also be connected to the datalogger’s RS-232 port via the 14392 null modem
cable.
A remote RF430 must use the 14392 null modem cable to connect the RF430’s
RS-232 port to the datalogger’s port.
Radios connected to the datalogger’s RS-232 port must use a 12-
Vdc field cable (item #14291) or AC adapter to furnish 12 V to
the Power connector on the radio.
