Section 11. Glossary 502 Term. node Part of the description of a datalogger network when using LoggerNet. Each node represents a device that the communication server will dial through or communicate with individually. Nodes are organized as a hierarchy with all nodes accessed by the same device (parent node) entered as child nodes. A node can be both a parent and a child. Term. NSEC Eight-byte data type divided up as four bytes of seconds since 1990 and four bytes of nanoseconds into the second. Term. null-modem A device, usually a multi-conductor cable, which converts an RS-232 port from DCE to DTE or from DTE to DCE. Term. Numeric Monitor A digital monitor is datalogger support software (p. 604). Term. offset a term, often a parameter in a CRBasic measurement instruction, to designate the y-intercept, shifting factor, or zeroing factor in a linear function. For example, when converting °C to °F, the equation is °F = °C*1.8 + 32. The factor 32 is the offset. Term. ohm The unit of resistance. Symbol is the Greek letter Omega (Ω). 1.0 Ω equals the ratio of 1.0 volt divided by 1.0 ampere. Term. Ohm's Law Describes the relationship of current and resistance to voltage. Voltage equals the product of current and resistance (V = I*R). Term. on-line data transfer Routine transfer of data to a peripheral left on-site. Transfer is controlled by the program entered in the datalogger. Term. operating system The operating system (also known as "firmware") is a set of instructions that controls the basic functions of the CR6 and enables the use of user written CRBasic programs. The operating system is preloaded into the CR6 at the factory but can be re-loaded or upgraded by the CR6 user using Device Configuration Utility (p. 116) software. The most recent CR6 operating system file is available at www.campbellsci.com. Term. output A loosely applied term. Denotes a) the information carrier generated by an
