Section 3. Overview 3.1.5.1 Firmware: OS and Settings Read More! See CR200(X) Configuration (p. 59). Firmware consists of the operating system (OS) and durable configuration settings. OS and settings remain intact when power is cycled. Note The CR200(X) is shipped factory ready with all settings and firmware necessary to communicate with a PC via RS-232 and to accept and execute user application programs. OS upgrades are occasionally made available at www.campbellsci.com. For more complex applications, some settings may need adjustment. Adjustments are accomplished with DevConfig Software (DevConfig (p. 59)) or through datalogger support software (see Support Software (p. 143)). OS files are sent to the CR200(X) with DevConfig or through the program Send button in datalogger support software. When the OS is sent via DevConfig, most settings are cleared, whereas, when sent via datalogger support software, most settings are retained. 3.1.5.2 User Programming Read More! See Programming (p. 69) and CRBASIC Programming Instructions (p. 93) and CRBASIC help for more programming assistance. A CRBASIC program directs the CR200(X) how and when sensors are to be measured, calculations made, and data stored. A program is created on a PC and sent to the CR200(X). Two Campbell Scientific software applications, Short Cut and CRBASIC Editor, create CR200(X) programs. • Short Cut creates a datalogger program and wiring diagram in four easy steps. It supports most sensors sold by Campbell Scientific and is recommended for creating simple programs to measure sensors and store data. • Programs generated by Short Cut are easily imported into CRBASIC Editor for additional editing. For complex applications, experienced programmers often create essential measurement and data storage code with Short Cut, then edit the code with CRBASIC Editor. Note that once a Short Cut generated program has been edited with CRBASIC Editor, it can no longer be modified with Short Cut. 3.1.6 Memory and Data Storage Read More! See Memory and Data Storage (p. 129). The CR200(X) has 2K SRAM for communication buffers, calculations, and variables, and 60K Flash EEPROM for the operating system and user program. The CR200 originally had a 128K Serial Flash EEPROM for data storage. Campbell Scientific has increased the data storage memory from 128 kbytes to 30
Section 3. Overview 512 kbytes in newer CR200s and in all CR200(X)s. CR200s with the increased memory have "512K" on their label. Figure 26: CR200(X) Wiring Panel 3.1.7 Communications Overview Read More! See Telecommunications and Data Retrieval (p. 131). The CR200(X) communicates with external devices to receive programs, send data, or act in concert with a network. The primary communication protocol is PakBus. Modbus is also supported. 3.1.7.1 PakBus Read More! See PakBus Overview (p. 133). The CR200(X) communicates with Campbell Scientific support software, telecommunication peripherals, and other dataloggers via PakBus, a proprietary network communications protocol. PakBus is a protocol similar in concept to IP (Internet protocol). By using signatured data packets, PakBus increases the number of communications and networking options available to the CR200(X). Communication can occur via RS-232 or RF. 31
