Description
This is an addendum to the Spread Spectrum Wireless Data Transceiver User Manual. It covers
details applicable specifically to using the FreeWave FGRIO Master and Slave modems. Please
use this addendum in conjunction with the User Manual.
The FreeWave Technologies FGRIO System provides outstanding performance and versatility
in wireless transmission of process-control signals. FGRIO offers “transparent” acquisition,
transport and reconstruction of analog, digital and power signals, eliminating the need for associated buried wiring. The RTU requires no altered programming. The FGRIO is Class 1 Div 2
approved and is lower-cost and provides better signal integrity than vulnerable wiring.
The FGRIO System is based upon wireless RF Technologies. RF is subject to interference and
communication interruptions. It should not be expected, therefore, to provide 100% communication, 100% of the time. The FGRIO System should not be used without proper provisions to
ensure safety upon loss of radio communications.
Glossary
FGRIO Master– FreeWave wireless radio transceiver that operates as a Master for up to 4
FGRIO or FGR2-IO Slaves, and can operate as a Slave in a point to multipoint network. The
FGRIO Master can receive over air a total of 4 analog input signals and 4 digital input signals
from up to 4 FGRIO or FGR2-IO Slaves. It can also transmit up to 4 digital output signals
over air to the FGRIO or FGR2-IO Slaves. The FGRIO Master does not operate as a Slave/
Repeater in the SCADA system.
FGRIO Slave – FreeWave wireless radio transceiver that accepts up to a total of 4 input signals
from sensors, then transmits these signals over air to the FGRIO Master. Two of the 4 available
input signals can only be transmitted as analog signals and are labeled as Analog Input 1 and
Analog Input 2 on the Slave’s terminal block. The other two input signals may be either analog
or digital inputs, depending on the user’s needs. The FGRIO Slave can also receive over air 2
digital output signals and a sensor power control signal from the FGRIO Master.
FGR2-IO Slave – New generation FreeWave wireless radio transceiver that accepts up to a total of 4 input signals from sensors, then transmits these signals over air to the FGRIO Master.
Two of the available 4 input signals can only be transmitted as analog signals and are labeled as
Analog Input 1 and Analog Input 2 on the Slave’s terminal block. The other two input signals
may be either analog or digital inputs, depending on the user’s needs. The FGR2-IO Slave can
also receive over air 2 digital output signals and a sensor power control signal from the FGRIO
Master. The FGR2-IO has a line-of-sight range of 60 miles, compared to the 2 mile line-ofsight range of the FGRIO Slave.
A note about terminology: The phrase ‘FGRIO System’, when used in this manual, will refer
to any system that uses an FGRIO Master in conjunction with either FGRIO or FGR2-IO
Slaves. IO Slave will refer to either an FGRIO Slave or an FGR2-IO Slave.

Glossary (cont.)
Analog Circuit– An electronic circuit that operates with currents and voltages that vary continu-
ously with time and have no abrupt transitions between levels. Temperatures, pressures, or flow
rates are all represented by analog circuits.
Digital Circuit– An electronic circuit that functions as though currents or voltages exist only at
one of a set of discrete levels, all transitions between levels being ignored. The states of a digital
circuit are often referred to as on or off, high or low.
VSNS- This is screw terminal # 7 on the IO Slave. This is an output used to power sensors/
transmitters. The maximum output voltage of this terminal is 20VDC for the FGRIO-S and
30VDC for the FGR2-IOS-C-U and FGR2-IOS-CE-U

FGRIO Master
(2) Call Book– IO Slaves’ serial numbers must be programmed in the FGRIO Master’s Call
Book. In addition, the Network ID must be set to the same ID as the rest of the network.
Programming both the Call Book and Network ID settings is unique to the FGRIO System
and must be done for both integrated and stand alone applications.
(3) Radio Transmission Characteristics
(1) Max Packet Size and (2) Min Packet Size– The FGRIO System requires a minimum
combined packet size of 48 Bytes. The following is a list of the available packet sizes that can
be used.
(4) RF Data Rate– The RF Data Rate must be set to 3 when using the FGRIO System. This
is for applications that are stand alone or when integrated into an existing FGR network.
MultiPoint Parameters-
(0) Number Repeaters– This setting must be set to 1 for all FGR and IO radios in the
Network.
(6) Network ID– In addition to entering the IO Slaves’ serial numbers in the Call
Book, the Network ID being used for the Network must be set from 1-4095. (Do NOT
use 255). Programming both the Call Book and Network ID settings is unique to the
FGRIO System and must be done for both integrated and stand alone applications.
Note: The FGRIO Master does not function as a Slave/Repeater in the SCADA network.
