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 approval pending 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 insure safety upon loss of radio communications.

Glossary FGRIO Master– FreeWave wireless radio transceiver that operates as a Master for up to 4 FGRIO Slaves, and, operates 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 Slaves. It can also transmit up to 4 digital output signals over air to the FGRIO Slaves. FGRIO Slave– FreeWave wireless radio transceiver that accepts up to 2 analog and 2 digital input signals from a sensor, then transmits those signals over air to the FGRIO Master. The FGRIO Slave also receives over air 2 digital output signals and a sensor power control signal from the FGRIO Master. Analog Circuit– An electronic circuit that operates with currents and voltages that vary continuously 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.

1. Select which FGRIO Slave you are mapping to the FGRIO Master. This is determined by the Call Book Entry # that lists the FGRIO Slave’s serial number in the FGRIO Master’s Call Book. 2. Next, determine if you are mapping Analog/Digital Input # 1 or # 2 of the FGRIO Slave to the FGRIO Master. 3. Enter the value listed in the table for the Analog or Digital Output of the FGRIO Master in Menu 9 of HyperTerminal. 4. Map unused FGRIO Master Analog/Digital Outputs to “0”. Multiple FGRIO Master Outputs will not mirror the same FGRIO Slave Input. EXAMPLE To map Analog Output 1 of the FGRIO Master to Analog Input 2 of the FGRIO Slave (serial # 930-004), entry (5) in the FGRIO Setup menu will have a value of 2. This is calculated by first checking the Call Book entry # of FGRIO Slave #930-004 (See Figure 8). The entry # is 0. Next, go to the table above, find call book entry # 0, then go to the column for FGRIO Slave Analog Input #2. The value listed is 2. A 2 will be entered for Analog Output #1 of the FGRIO Master.

(4) RF Data Rate– The RF Date 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.

(8) Retry Timeout– By lowering the Retry Timeout, the inactive link time between the FGRIO Master and FGRIO Slave can be reduced when going from autonomous mode to connecting back to the FGR Network. If the Network Master goes down, the FGRIO Master and Slave will continue to operate in autonomous mode. When the Network Master comes back up, the FGRIO Master will break the link with the FGRIO Slave to reestablish a link with the Network Master. Once the FGRIO Master is linked to the Network Master, then the FGRIO Slave will be able to link back to the FGRIO Master. With a lower Retry Timeout setting, it will take less time for the FGRIO Slave to link to the FGRIO Maser. FreeWave Technologies, 1880 S.

Installation (cont.) FGRIO Slave (2) 1-5 Volt Sensor • Sensor Output Wire is connected to Analog Input 1 screw terminal # 8 or Analog Input 2 screw terminal # 10 on the phoenix connector of the FGRIO Slave. (3) 4-20 Milliamp Sensor • Consists of a 2 wire connection from the Sensor to the FGRIO Slave. • An external resistor (typically 249 Ohms) is required to convert 4-20 milliamps to 15 volts. The resistor goes from the desired Analog Input to Ground screw terminals on the phoenix connector of the FGRIO Slave. • Sensor Power Supply (High) Wire is connected to VSNS screw terminal #7 on the phoenix connector of the FGRIO Slave. • Sensor Output (Low) Wire is connected to the same Analog Input as the resistor on the phoenix connector of the FGRIO Slave.

Installation (cont.) FGRIO Slave (3) Digital Input • Switch Output Wire is connected to Digital Input 1 screw terminal # 1 or Digital Input 2 screw terminal # 2 on the phoenix connector of the FGRIO Slave. • Switch Ground Wire is connected to Ground screw terminal # 3,6,9 or 12 on the phoenix connector of the FGRIO Slave. If the Switch Ground Wire is not returned to the FGRIO Slave, the potential differ ence between the FGRIO Slave Ground and the Dry Contact Closure (Switch) Ground should not exceed 1 Volt. • In the case of a 3 wire digital transducer, set up similarly to the 1-5V analog sensor, except with the signal wire connected to a Digital Input. (4) Digital Output • Digital Output is an open drain field effect transistor connected to Ground. It connects to Ground when zero volts is connected to the controlling Master Digital Input. • The current rating for Digital Output is 2 amps or less. The Digital Output will selfprotect if a current of more than 2 1/2 amps is drawn and automatically retry at .16 second intervals. • If power on the Solenoid (end device) is not driven from the same power supply as the FGRIO Slave, that source must be equal to or less than the FGRIO Slave power supply voltage. Within the FGRIO Slave, a 3 amp rated Schottky Diode is connected from each Digital Output to the radio power supply terminal for clamping the Solenoid fly back current. If the relay supply voltage exceeded the radio supply voltage, then current would flow through that diode back to the radio, potentially causing an overvoltage condition. Typical set up of Digital Output wiring between Solenoid and FGRIO Slave:

Installation (cont.) FGRIO Master (1) Rx, Tx, B+ • Receive, Transmit, and Power are available on screw terminals of the FGRIO Master phoenix connector as well as the 10 pin header. (2) Analog Output • The Analog Output wire is connected from the Analog Output 1,2,3 or 4 screw terminal on the FGRIO Master phoenix connector to the Analog Input of the RTU (destination device). • Common Ground is required. It is recommended to run a Ground wire from a FGRIO Master Ground screw terminal to Ground on the RTU. NOTE: Analog Output is 1-5 V at low current, so any 4-20 mA current sensing resistor on the RTU MUST BE REMOVED. (3) Digital Output • The Digital Output wire is connected from the Digital Output 1,2,3 or 4 screw terminal on the FGRIO Master phoenix connector to the Digital Input of the RTU (destination device). • Common Ground is required. It is recommended to run a Ground wire from the FGRIO Master Ground screw terminal to Ground on the RTU. NOTE: The Digital Output actively drives Low (.4V) and High (4.0V). Remove any RTU input pull-up resistor, if less than 10 K ohms. (4) Digital Input • The RTU Digital Output Wire is connected to Digital Input 1,2,3 or 4 screw terminal on the phoenix connector of the FGRIO Master. An internal 10Kohm pullup to +5V is provided. • The RTU Ground Wire is connected to any of the Ground screw terminals on the phoenix connector of the FGRIO Master. (5) Sensor Power • To minimize power drain of the FGRIO Slave Solar/Battery System, an input terminal called Sensor Power is provided on the FGRIO Master phoenix connector. • If the RTU provides a switched sensor power output, connect it to this terminal. • The state of that sensor power will be mirrored at the FGRIO Slave, powering the sensors at the FGRIO Slave on and off. It is necessary to change FGRIO Setup sub menu (A) to “1” (Gated). • The sensor power terminal both activates sensor power at the controlled FGRIO Slaves, and activates Analog Outputs at the FGRIO Master interface board, when in Sensor Power “Gated” mode.

Installation (cont.) FGRIO Master (6)Link Alarms • Link Alarm 1 is an alarm reflecting loss of communication on any path. A wire is run from the Link Alarm 1 screw terminal to the Link Alarm screw terminal on the RTU. • Link Alarm 2 (CMD Alarm) indicates that a Digital Output or Sensor Power command was not carried out due to an over-current fault. A wire is run from the Link Alarm 2 screw terminal to the Link Alarm screw terminal on the RTU. Note: The mini phoenix connector of the FGRIO Master and Slave can accept a single wire up to 16 gauge. Smaller wire is required for 2 wires, or wire + resistor into the same screw terminal.

Frequently Asked Questions Q: Can FGRIO be used with a 1 watt radio? A: The FGRIO Master operates as a standard FGR 1 watt radio with a 60 mile line of sight range. The FGRIO Slave functions as an FGR radio with a 2 mile line of sight range.

Q: Can the FGRIO radios be repeated through our other radios to extend the range? A: From the FGRIO Slave to the FGRIO Master, repeaters cannot be used. From the FGRIO Master to the rest of the existing network, repeaters can be used as they already are in exist ing FreeWave networks.

Q: Can the FGRIO Master operate as Slave/Repeater in the overall network? A: The FGRIO Master currently does not have the capability to operate as a Slave/Repeater. It does function as the Master to the FGRIO Slave, and as a Slave to the rest of the network.

Q: Can data be sent directly from the FGRIO Slave to the Master of the FreeWave network? A: No. The FGRIO system functions as wire replacement only. The FGRIO Slave does not have the capability of transmitting data directly to the Master of the network.

Frequently Asked Questions Q: What are the sizes of the FGRIO Master and Slave? A: The FGRIO Slave has the same footprint as the FGRO9 family. The FGRIO Master is a standard footprint FGRO9 plus an IO Interface board on top, differing only in width at 2.75 inches.

Q: What timing issues does FGRIO introduce? A: Although FGRIO mimics a wired connection, the electronics and communication heartbeat do cause some signal delay. The worst case delay for digital signals in either direction and the Sensor Power command from FGRIO Master to FGRIO Slave is 167 msec, assuming a robust link.
