The Sure Cross
®
Performance wireless I/O network provides reliable monitoring without wiring or conduit installation. The
SureCross wireless network operates independently or in conjunction with a host system, PLC, and/or PC software.
Each wireless network system consists of one Gateway and one or more Nodes. Devices ship with
factory-defined discrete,
analog, or a mix of discrete and analog inputs and outputs.

The Sure Cross
®
Performance network is a deterministic system—the network identifies when the radio signal is lost and
drives relevant outputs to
user-defined conditions. After the radio signal is reacquired, the network returns to normal
operation.
1.1 Gateways and Nodes
Every wireless network must have one Gateway, which schedules communication traffic and controls the I/O configuration
for the network, and one or more Nodes.
A Gateway is the master device within each radio network. Similar to how a gateway device on a wired network acts as a
“portal” between networks, the Sure Cross 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. 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.

1.2 GatewayPro
A GatewayPro combines the wireless capability of the standard Gateway with the protocol converter of a DX83 Ethernet
Bridge, resulting in a device that is the master of the wireless network and a slave to an Industrial Ethernet network.
The GatewayPro is treated the same as a standard Gateway, with the GatewayPro providing Modbus/TCP or EtherNet/IP
slave access to all the information on the wireless network instead of the Modbus 485 slave interface the standard Gateway
provides. There are two basic models of the GatewayPro:
