Verify Communications - Banner SureCross DX80 Manual

SureCross DX80 Gateway with Analog I/O
Address Mode
The SureCross wireless devices may use one of two types of addressing modes: rotary dial addressing or extended addressing. In
rotary dial address mode, the left rotary dial establishes the network ID and the right rotary dial sets the device ID. The wireless network
is restricted to a maximum of 16 devices.
Extended address mode uses a security code to "bind" Nodes to a specific Gateway. Bound Nodes can only send and receive informa-
tion from the Gateway to which they are bound. In extended address mode, wireless networks may contain up to 48 radio devices. For
more information on extended address mode, refer to the SureCross™ Wireless I/O Network product manual.
The device ships in rotary dial address mode by default, with the DIP switch in the OFF position. To use extended address mode, change
the DIP switch to the ON position.
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.
Host Configured
Selecting "Host Configured (override switches)" uses the factory's default configuration for this device or allows a host system to set
parameters. If the host configured option is not selected, use the DIP switches to configure the device parameters.
Link Loss Outputs
The SureCross™ DX80 wireless devices use a deterministic link time-out method to address RF link interruption or failure. When a radio
link fails, all pertinent wired outputs are sent to defined states until the link is recovered, ensuring that disruptions in the communications
link result in predictable system behavior.
Following a 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 to hold the last stable state/value. Use the DIP switches to select
the link loss output state.

Verify Communications

After powering up and binding the Gateway and its Nodes, verify all devices are communicating properly. Verify LED 1 is green. Until
communication is established with the Gateway, the Node's LED 2 flashes red. When communication is established, the Node's LED 1
flashes green.
A Node will not sample its inputs until it is communicating with the Gateway to which it is bound.

For Gateway and Ethernet Bridge systems, active Modbus communication refers to the communication between the Gateway and the
Ethernet Bridge. For GatewayPro systems, the Modbus communication LEDs refer to the communication internal to the Gateway Pro.
For Gateway only systems, the Modbus communication LEDs refer to the communication between the Gateway and its host system (if
applicable).
When testing the Gateway and Node, verify all radios and antennas are at least two meters apart or the communications may fail.
