The GRANITE 9/10 data acquisition system
The GRANITE 9/10 data logger provides fast communications, low power requirements, and built-in host and devices USB in a compact size. It includes digital I/O (C) terminals, which allow connection to virtually any digital or smart sensor. The GRANITE 9/10 in conjunction with GRANITE Measurement Modules can be collocated in a chassis or distributed over distances of thousands of feet and all behave as a single unit for the purposes of programming, synchronization, and data collection and storage.
Overview
The GRANITE 9/10 data logger is the main part of a data acquisition system (see GRANITE 9/10 data acquisition system components for more information). It has a central-processing unit (CPU), digital measurement inputs, analog and digital outputs, and memory. An operating system (firmware) coordinates the functions of these parts in conjunction with the onboard clock and the

The GRANITE 9/10 can simultaneously provide measurement and communications functions. Low power consumption allows the data logger to operate for extended time on a battery recharged with a solar panel, eliminating the need for ac power. The GRANITE 9/10 temporarily suspends operations when primary power drops below 9.6 V, reducing the possibility of inaccurate measurements.
Operations
The GRANITE 9/10 measures almost any sensor with an electrical response, drives direct communications and telecommunications, reduces data to statistical values, performs calculations, and controls external devices. After measurements are made, data is stored in onboard, nonvolatile memory. Because most applications do not require that every measurement be recorded, the program usually combines several measurements into computational or statistical summaries, such as averages and standard deviations.
Distributed measurements are one of the hallmarks of the GRANITE series. All modules are interconnected using CAT5e Ethernet cable. This makes running cables inexpensive and familiar. One of the advantage of distributed measurements is to take the GRANITE 9/10 to the sensors and shorten the sensor cables. This replaces many long sensor cables with a single inexpensive data cable. It also reduces the distance for signals to travel therefore reducing opportunities for corruption of the signals by noise.
Programs
A program directs the data logger on how and when sensors are measured, calculations are made, data is stored, and devices are controlled. The application program for the GRANITE 9/10 is written in CRBasic Campbell Scientific's BASIC-like programming language that supports analog and digital measurements, data processing and analysis routines, hardware control, and many communications protocols., a programming language that includes measurement, data processing, and analysis routines, as well as the standard BASIC instruction set. For simple applications, Short Cut A CRBasic programming wizard suitable for many data logger applications. Knowledge of CRBasic is not required to use Short Cut., a user-friendly program generator, can be used to generate the program. See also:
For more demanding programs, use the full-featured CRBasic Editor The CRBasic programming editor; stand-alone software and also included with LoggerNet, PC400, and RTDAQ software.. The CRBasic Editor help contains program structure details, instruction information and program examples: 
Programs are run by the GRANITE 9/10 in either sequential mode A CRBasic program execution mode wherein each statement is evaluated in the order it is listed in the program. or pipeline mode A CRBasic program execution mode wherein instructions are evaluated in groups of like instructions, with a set group prioritization.. In sequential mode, each instruction is executed sequentially in the order it appears in the program. In pipeline mode, the GRANITE 9/10 determines the order of instruction execution to maximize efficiency.
