Section 1 Overview Introduction The Starrett DataSure™ wireless network is designed to allow the transfer of data from electronic measuring tools to computers where measurements can either be easily logged or conveyed to an SPC software package. The wireless network environment allows tool operators to move freely without the constraints of data cables.
The power cables may be looped around the posts located near the power entry jack on the rear of the Gateway. This provides strain-relief to guard against accidental shutoff if the cable should become snagged and pulled away unintentionally. DataSure™ Operators Manual PT 6*****...
1.5.2 Routing Network - STRING Networks consisting of routers in a common line or ‘string’ dramatically increase radio range, but at the cost of loosing redundancy or alternate link paths between the network routers. DataSure™ Operators Manual PT 6*****...
STRING routing, while not a MESH, does offer additional network flexibility in layout for remote buildings or measuring stations away from the general area. Product Note: With the Starrett DataSure™, multiple networks can exist and operate under one roof, but must have separate Group Numbers.
Routers and Gateway network nodes have a broadcast radius of 30 meters (97 feet). With this knowledge, you can simply draw out a schematic floor plan of the area for the DataSure™ system to be deployed in and superimpose circles of the scaled radio ranges for each network element.

1.7.2 Device Identification To bring a tool in the DataSure™ network the operator has only to plug an EndNode into the tool’s data port and power them both on. When the EndNode comes within range of a Router or the Gateway, it will be automatically recognized by the wireless service.
32 tool channels. It is possible to run the network service with a maximum of five multiplexers configured at the same time. If there are no multiplexers currently configured on the DataSure™ Homepage, and a new EndNode and tool is powered up in the presence of the wireless network, then a Primary Multiplexer is automatically generated by the DataSure™...

EndNode is not exceeded (maximum of 10 stored measurements). Operators have the option to be located at the site of the tool, with the PC hosting the DataSure™ software, or at any remote location with a PC networked to the localhost PC. Alternatively, 3 party software applications (such as an SPC package) running on the localhost PC have the potential to solicit data from tools.
Data logs can be generated and then sent to SPC packages, or retained as work records. DataSure™ administrators can also use the log file as a diagnostic view of network performance.
• Explain the use of the Application Command Set Remote Network Monitoring If the PC running the DataSure™ utility software is attached to a computer network, such as a LAN, it is also possible to monitor and manipulate network activity from a remote PC.
These settings allow the operator to customize the performance of the wireless network and direct the flow of data through DataSure™ utility software. It is also possible to impair or impede network operability through inappropriate changes to some settings. Operators are encouraged to proceed with caution, and test their networks after changes are made.
