Analog Input and Output Scale
Use the DIP switch to select which current scale to use for all the device's analog inputs and outputs: 0 to 20 mA or 4 to 20 mA.
When using a 4-20 mA sensor with a 0-20 mA input, the sensor uses the 4-20 mA section of the total range. Using a 4-20 mA with
a 0-20 mA input allows you to determine when you have an error condition with the sensor. A normal input reading between 4 and
20 mA indicates a functioning sensor whereas a value below 4 mA indicates an error condition, such as a broken wire or loose
connection. This DIP switch is used only on the 0 to 20 mA models, not the 0 to 10V models.
Discrete Input Type
Select the type of discrete input sensors to use with this device: sourcing (PNP) sensors or sinking (NPN) sensors.
Link Loss Outputs
®
The Sure Cross wireless devices use a deterministic radio link time-out method to address RF link interruption or failure. When a
radio link fails, all pertinent wired outputs are set to defined states until the link is recovered, ensuring that disruptions in the
communications link result in predictable system behavior.
Following a radio link time-out, all outputs linked to the Node in question are set to de-energize (discrete outputs to zero, analog
outputs to 0 mA or 4 mA), energize (discrete outputs to one, analog outputs to 20 mA), or hold the last stable state/value. Use the
DIP switches to select the link loss output state.
Modbus/Software or DIP Switch Configured
In Modbus/Software Configured mode, use the User Configuration Software or a Modbus command to change the device
parameters. DIP switch positions 3 through 8 are ignored. In DIP Switch Configured mode, use the DIP switches to configure the
parameters listed in the table.
Transmit Power Levels
The 900 MHz radios transmit at 1 Watt (30 dBm) or 250 mW (24 dBm). While the Performance radios operate in 1 Watt mode, they
cannot communicate with the older 150 mW radios. To communicate with 150 mW radios, operate this radio in 250 mW mode. For
2.4 GHz models, this DIP switch is disabled. The transmit power for 2.4 GHz is fixed at about 65 mW EIRP (18 dBm), making the
2.4 GHz Performance models automatically compatible with older 2.4 GHz models.
Configuring Universal Analog Inputs for mA or V
To configure inputs to use 0 to10V instead of 0 to 20mA, remove the installed resistors from the marked locations on the wiring
board. For example, to make analog input 1 a 0 to 10V input, follow these instructions.
A4 A2
A1
A3
Remove resistor in A1 slot
to make Analog IN 1 a 0–10V input.

Step 1. Cut out the resistor installed in the A1 (analog 1) slot. (Your wiring
board may differ slightly from the board shown. Use the board's labels to
confirm you have selected the correct resistor to cut.)
Step 2. Launch the User Configuration Tool software.
Step 3. Change the units parameter for this particular input on this device
(Gateway or Node) to use voltage instead of milliamps. Refer to the
Modbus Register table for the I/O number for each analog input. Writing
a four (4) to the Units parameter defines the units as 0 to 10V. Writing a
two (2) to the Units parameter defines the units as 0 to 20 mA.
