on the Node in the list and select Get Signal Quality.
I/O Mapping
Use the I/O Mapping screen to easily map one SureCross device’s inputs to another SureCross device’s outputs, as long as both devices
are part of the wireless network.
To begin mapping your I/O:
1. Select the source device from the drop-down menu. After the source device is selected, the UCT program reads the existing map-
ping and I/O type configuration of the source device inputs and displays it on screen. In the example shown, I/O 1 through 4 are
discrete inputs on the source device (Gateway) and I/O 5 and 6 are 0–20 mA analog inputs.
2. To map the source input to a specific destination, select the destination device and output number from the drop-down lists. When
the destination device number and output point is selected, the output type is automatically read from the destination device and
displayed on screen. When the device is in the network, the arrow changes from red to green.
3. Depending on how you want the network to react during a loss of radio communication, select the default output value or the hold
last state checkbox.
4. Repeat steps two and three to map each input on the source device to its respective output point and device.
5. Click the Send button to write these settings to the network devices.
6. To configure another source device, repeat steps one through five. Remember to click on the Send button to write these settings to
the network device.
Source. The source device may be the Gateway or any of the Nodes physically present in the network. Device I/O points 1 through 8 are
inputs on most DX80 wireless models. Refer to the device's datasheet for exact input and output configurations. Any I/O points disabled
on the source device are grayed out on screen. The source type field displays the input structure for that given input. Sample input
structures include discrete, 0–20 mA, 4–20 mA, 0–10V dc, degrees C, degrees F, and raw.
Destination, I/O, and Type. Use the drop-down list to select the destination device. Device I/O points 9 through 14 are outputs on all
DX80 wireless models. The destination type field is set to None when the output point is not enabled or the destination type field cannot
be read.
Null and Span. When a temperature is the source and the destination is 4-20 mA, the configuration requires the definition of the null and
the span parameters. The null value is the starting temperature to be associated with 4 mA. The span is the entire temperature range that
is to be associated with 4-20 mA.
For example, to map an input temperature range from 20 degrees to 220 degrees to a 4-20 mA output, set the null value to 20 and the
span to 200. Setting the null value to 20 establishes a starting point of 20 degrees associated to 4 mA. Setting the span to 200 defines
the full range associated with 4-20 mA to 220 degrees. All temperature ranges between 20 and 220 degrees correspond to a proportional
value between 4 mA and 20 mA.
