7.6.3.5.2 Basics Section 7. Installation Caveats • Network Planner aids in, but does not replace, the design process • It aids development of PakBus networks only. • It does not make hardware recommendations. • It does not generate datalogger programs. • It does not understand distances or topography; that is, it does not warn the user when broadcast distances are exceeded or identify obstacles to radio transmission. For more detailed information on Network Planner, please consult the LoggerNet manual, which is available at www.campbellsci.com. PakBus Settings • Device addresses are automatically allocated but can be changed. • Device connections are used to determine whether neighbor lists should be specified. • Verification intervals will depend on the activities between devices. • Beacon intervals will be assigned but will have default values. • Network role (e.g., router or leaf node) will be assigned based on device links. Device Links and Communication Resources • Disallow links that will not work. • Comparative desirability of links. • Prevent over-allocation of resources. • Optimal RS-232 and CS I/O ME baud rates based on device links. • Optimal packet size limits based upon anticipated routes. Fundamentals of Planning a Network • Add a background (optional). • Place stations, peripherals, etc. • Establish links. • Set up activities (scheduled poll, callback). • Configure devices. • Configure LoggerNet (adds the planned network to the LoggerNet Network Map). 113
