Analog Input
The analog input provides 13V/18V (selectable in software, see page 11) to the attached sensor. The analog
input can operate in either current (4-20mA), or voltage (1-5V). The input mode must be set by the slide switch.
Slide the switch up to Volts for a voltage input, or down to mA for a current input.

Relay Output
The RANGER has a single latching SPDT relay which may be controlled remotely from the server or by using the
RANGER’s internal relay control logic. The Relay will connect the COM terminal to NC when de-energized and
the COM will be connected to the NO terminal when energized

Expansion Cards
The RANGER has the option of being ordered with daughter cards to expand the I/O capabilities. Currently,
four expansion cards are offered: the 2AI/1DI, Modbus, HART, RTD and SDI-12cards. If the expansion cards
are installed separately it must be enabled using the RANGER ToolKit by loading the appropriate firmware.
RANGER with a 2AI/1DI installed
2AI/1DI
The 2AI/1DI card provides the RANGER with two (2) additional analog inputs, and one (1) additional digital
input.
These inputs operate the same as the analog and digital inputs of the base model. The analog inputs can be set
to 4-20mA mode or 1-5Vdc mode via onboard switches. When installed, additional input configuration tiles will
become available on the unit’s SignalFire Cloud configuration page. An optional junction box provides for easy
wiring to multiple sensors.

Rev 1.1
Modbus RS-485
The Modbus card provides the RANGER with the ability to read a Modbus sensor over two-wire RS-485.
Follow the diagram below for wiring the Modbus expansion card to a sensor. Sensors can be powered
off the RANGER’s onboard analog sensor power output. Like the analog sensor, its voltage is set in the
RANGER configuration tile (see page 11). The RANGER can provide up to a total of 60mA at 18Vdc for all
attached sensors. If more power is needed, or to conserve battery life, it is recommended the sensors be
powered with an external DC source. Follow the wiring diagram below for integrated and externally
powered options.
The attached sensors need to each have a unique Modbus ID.

HART
The HART card provides the RANGER with the ability to power a HART transmitter and read its
variables. The HART sensor should be wired to the RANGER’s HART terminals as shown below. Note
that the HART card also has 1 digital input available.
The system can supply up to 18Vdc to the sensors and then read the HART data from each sensor. Due to the
250Ω series resistance, every additional sensor will draw 4mA in multi-drop mode, dropping the output voltage
by 1Vdc. For example, if 4 HART devices are connected the total loop current will be 16mA, resulting in 4Vdc
being dropped across the 250Ω load resistor in the SignalFire node. If the RANGER is configured to output
18Vdc, this leaves 14V available to power the sensors.
If using an external power source, remove the jumper from the HART card. It is recommended to place a 250Ω
resistor in series with the source unless the supply already has a series resistor, to ensure proper HART
communication across the bus. It is up to the operator to ensure that the resulting voltage of the source minus
the drop across the series resistor meets the minimum voltage requirements of all attached sensors.
The attached sensors need to each have a unique HART ID. If their ID’s have not been set up before connecting,
they can be set up through the RANGER ToolKit.

SDI-12
The SDI-12 card provides the RANGER with the ability to read from SDI-12 sensors. The SDI-12 bus
contains three lines, Power (12Vdc), Data, and GND. Across multiple sensors, these three lines must be
connected in parallel, such that all the Power lines are connected together, the Data lines are all
connected together, and GND lines are connected together.
If the RANGER is powering the sensors, it can provide up to 60mA at 12Vdc for all attached sensors. It is up to
the operator to ensure this limit is not exceeded. If the sensors are powered externally, the Power terminal of
the SDI-12 card must still be connected to the positive power terminal of each sensor and the external voltage
source.
The attached sensors need to each have their own unique SDI-12 ID. If their ID’s have not been set up before
connecting, they can be set up through the RANGER ToolKit.

RTD
The RTD card supports a direct connection to a 3-wire P100 RTD temperature probe. The RTD should be
wired as pictured below.

The F+ and RTD+ terminals should be wired to the two wires with the same color from the RTD (typically red),
while the RTD- should be connected to the third RTD wire (typically white).

Power Options
Lithium Battery Pack (4DPak)
The internal lithium battery pack is the default power source for the ranger, simply plug the battery pack into
the RANGER PCB battery connector to power the RANGER on.
DC-DC converter
In situations where DC power is available, the RANGER can be ordered with an internal DC-DC converter that
accepts 9-36Vdc from an external source. The DC-DC converter is installed in the battery compartment of the
RANGER and has a pigtail cable to connect to the RANGER PCB. Simply connect your DC power source to the
“GND” and “Vin” screw terminals on the converter to power on the system.
HC-Solar System
SignalFire offers a solar system that consists of a bracket containing a solar panel and integrated battery and
solar charger assembly. The solar system is connected to the RANGER PCB using the battery connector.
Internal Lithium Battery Replacement
Battery Packs can be changed with the node in place.
1. Unplug the battery from the PCB, by depressing the locking clip on the connector.
2. Push up on the top metal plate to allow you to remove and replace the battery
3. Connect the battery to the main PCB battery connector.

External Antenna Conversion
The Wall Mount RANGER is shipped with its internal antenna connected to the cellular modem. If an external antenna is
needed the user can switch to the external antenna by following the following steps.
Disconnect the internal antenna connector by
unscrewing the SMA connection. The antenna does
not need to be removed. Tuck the connector in the
back of the box.
