Section 3. Overview Table 3. Internal Lithium Battery Specifications Manufacturer Renata Model CR2016 (3.6V) Capacity 80 mAh Self-discharge rate 1%/year @ 23°C Operating temperature range -40°C to +85°C 3.2 PC Support Software Read More! See Support Software (p. 143). Several datalogger support software products for Windows are available. Software for datalogger setup and simple applications, PC200W and Short Cut, are available at no cost at www.campbellsci.com. For more complex programming, telecommunications, networking, and reporting features, fullfeatured products are available from Campbell Scientific. • PC200W Starter Software is available at no charge at www.campbellsci.com. It supports a transparent RS-232 connection between PC and CR200(X), and includes Short Cut for creating CR200(X) programs. Tools for setting the datalogger clock, sending programs, monitoring sensors, and on-site viewing and collection of data are also included. • PC400 supports a variety of telecommunication options, manual data collection, and data monitoring displays. Short Cut and CRBASIC Editor are included for creating programs. PC400 does not support complex communication options, such as phone-to-RF, PakBus® routing, or scheduled data collection. • LoggerNet supports combined telecommunication options, customized data monitoring displays, and scheduled data collection. It includes Short Cut and CRBASIC Editor for creating programs. It also includes tools for configuring, trouble-shooting, and managing datalogger networks. LoggerNet Admin and LoggerNet Remote are also available for more demanding applications. 34
