The SureCross

DX80 network is a deterministic system—the network identifies when the radio signal is lost and drives relevant outputs
to user-defined conditions. Once the radio signal is reacquired, the network returns to normal operation.

DX80 Gateways and Nodes
A Gateway is the master device within each radio network. Every wireless network must have one Gateway that schedules communica-
tion traffic and controls the I/O configuration for the network. A radio network contains only one Gateway, but can contain many Nodes.
Similar to how a gateway device on a wired network acts as a “portal” between networks, the SureCross Gateway acts as the portal
between the wireless network and the host controller. When the Gateway, using its Modbus RTU RS-485 connection, is a Modbus slave
to a Modbus RTU host controller, the wireless network may contain up to 47 Nodes in a single wireless network and the Gateway holds
the Modbus registers of all wireless devices within the network.
A Node is a wireless network end-point device used to provide sensing capability in a remote area or factory. The Node collects data
from sensors and communicates the data back to the Gateway. Nodes are available in a wide variety of power or input/output options.
Each Node device can be connected to sensors or output devices and reports I/O status to the Gateway.
Host Systems
Host-connected systems collect I/O data for logging, controlling other devices, or performing calculations.
Host-connected systems can contain up to 15 Nodes (when using Rotary Dial Addressing Mode) or 47 Nodes (when using Extended
Addressing Mode) within a single network. Inputs from Nodes within the network are transmitted to the Gateway, which communicates
the information to a host device for processing. While the Gateway is the master device within the radio network, the Gateway may be a
slave to the Modbus network.
Host-connected DX80 wireless systems are configured using an Ethernet network connection and a common Web page browser. An
Ethernet connection can be established from a DX80 GatewayPro device or a DX83 Ethernet Bridge device serially connected to the
DX80 Gateway.
Setting Up Your Wireless Network
To set up and install your wireless network, follow these steps:
1. Configure the DIP switches of all devices.
2. Connect the sensors to the SureCross devices.
3. Apply power to all devices.
4. Form the wireless network by binding the Nodes to the Gateway. If the binding instructions are not included in the datasheet, refer to
the product manual for binding instructions.
5. Observe the LED behavior to verify the devices are communicating with each other.
6. Conduct a site survey between the Gateway and Nodes. If the site survey instructions are not included in this datasheet, refer to the
product manual for detailed site survey instructions.
7. Install your wireless sensor network components. If installation instructions are not included in this datasheet, refer to the product
manual for detailed installation instructions.
