A SureCross Wireless Network requires a Gateway radio at the IntelliLogger location to receive data from the remotely located SureCross™ Nodes. This Gateway is connected to the IntelliLogger Modbus port and serves to buffer readings collected from the network of wireless transducer interface Nodes.

As the IntelliLogger executes its application Program Net, the IntelliLogger will query Modbus registers within the Gateway that are periodically updated with data from the various Nodes in the wireless network. The IntelliLogger then utilizes these data readings in its Program Net to store them to IntelliLogger memory, trigger alarms, include in Emails or Web pages, etc.

Wireless Network Component Details

The hardware serial connection between the Gateway radio module and the IntelliLogger serial port (configured for Modbus RTU Master) is via a Logic Beach model SCC-1, RS-485 to RS-232 converter. This converter simply serves to convert the RS-485 hardware port on the Gateway to the RS-232 signal levels used by the IntelliLogger Modbus port. The Gateway can be physically located distant (up to several thousand feet) from the IntelliLogger as the RS-485 interface between the IntelliLogger/SCC-1 and the Gateway is a simple twisted pair cable. This facilitates location of the Gateway to optimize the RF connectivity with the Nodes while the IntelliLogger can be located in a more easily accessed user location for viewing the real-time values on its LCD, observing operation or connecting to other hardwired signal or transducer inputs.
