Connections and Components Radio LEDs - The Radio TX LED (green) flashes each time a radio packet is sent. This LED will blink rapidly while searching for the radio network and at boot up. - The Radio RX LED (red) blinks on each received radio packet. 4 Status LEDs - The STATUS LED (green) will blink on when the pressure sensor is sampled. - The ERROR LED (red) will blink to indicate an error condition.
Setup The Pressure Scout needs to be set up for correct operation before being fielded. The configurable items include: - Network selection - Check-in period selection - Modbus Slave ID setting - Optional alarm thresholds and scaling 5 All settings are made using the SignalFire Toolkit PC application and a USB-serial programming cable available from SignalFire. WARNING: Perform the steps in this section (Setup) in a safe location only.

Network Setting The network is set using the SignalFire Toolkit. The network, network group, and corporate ID (replaced with Encryption) settings must match those of the gateway (and other nodes) in order for them to communicate 7 Encryption Starting with firmware version 0.50, it is possible to encrypt over-the-air transmissions to prevent tampering.
Modbus Slave ID The Modbus Slave ID can be set with the SignalFire Toolkit. Each remote device connected to the gateway must have a unique Modbus Slave ID (1-240). 8 Alarm Threshold Settings Optional alarm threshold settings are available which allow for rapid pressure sample interval (5 or 15 seconds) and will cause the Pressure Scout to check-in immediately if the threshold is crossed.
Remote Modbus Register Mapping The Scout Node sends data to a SignalFire Telemetry Modbus Gateway. The data that is sent to the gateway is available at the gateway in registers where it can then be read by a Modbus RTU. Consequently, the node needs to have a unique (to the network it is in) Modbus slave ID which the gateway will use to store its unique data. Modbus Registers Every check-in period, the sensors are read and data is sent to the gateway.
Mounting and Care The Pressure Scout unit comes with an integrated pressure sensor with a ½” MNPT process fitting. The Scout is mounted directly to the pressure source. It is important to mount the Scout so it is vertically orientated with the pressure fitting facing down. Internal Lithium Battery Replacement Battery Packs can be changed with the node in place. 1 2 3 4 5 Unscrew the cover from the base. Unplug the battery from the PCB, by depressing the locking clip on the connector.
Configuration / Debug WARNING: Only connect to the debug port in a safe area! 11 Debug and configuration information is available if a connection is made via the debug port on the main board. A USB converter cable (available from SignalFire) must be used for this interface. Debug and advanced configuration may be done using the SignalFire Toolkit PC application.
