Section 3. Overview Advantages of PakBus: • Simultaneous communication between the CR200(X) and other devices. • Peer-to-peer communication-no PC required. • Other PakBus dataloggers can be used as "sensors" to consolidate all data into one CR200(X). • Routing - the CR200(X) cannot act as a router, passing on messages intended for another logger, but other dataloggers can. PakBus supports automatic route detection and selection. • Datalogger to datalogger communications-special CRBASIC instructions simplify transferring data between dataloggers for distributed decision making or control. • In a PakBus network, each datalogger is set to a unique address before being installed in the network. Default PakBus address is 1. To communicate with the CR200(X), the datalogger support software (see Telecommunications and Data Retrieval (p. 131)) must know the CR200(X)'s PakBus address. The PakBus address is changed using the DevConfig software, CR200(X) status table, or PakBus Graph software. 3.1.7.2 Modbus Read More! See Modbus (p. 139). The CR200(X) supports Modbus Master and Modbus Slave communication for inclusion in Modbus SCADA networks. 3.1.8 Maintenance Overview Read More! See Care and Maintenance. With reasonable care, the CR200(X) should give many years of reliable service. 3.1.8.1 Protection from Water The CR200(X) and most of its peripherals must be protected from moisture. Moisture in the electronics will seriously damage, and probably render unrepairable, the CR200(X). Water can come from flooding or sprinkler irrigation, but most often comes as condensation. In most cases, protecting from water is as easy as placing the CR200(X) in a weather tight enclosure with desiccant and elevating the enclosure above the ground. The CR200(X) is shipped with desiccant to reduce humidity. Desiccant should be changed periodically. Do not completely seal the enclosure if lead acid batteries are present; hydrogen gas generated by the batteries may build up to an explosive concentration. 32
Section 3. Overview 3.1.8.2 Protection from Voltage Transients Read More! See Grounding (p. 55). The CR200(X) must be grounded to minimize the risk of damage by voltage transients associated with power surges and lightning induced transients. Earth grounding is required to form a complete circuit for voltage clamping devices internal to the CR200(X). 3.1.8.3 Calibration Read More! See Self-Calibration p. 41. The CR200(X) uses an internal voltage reference to routinely calibrate itself. 3.1.8.4 Replacing the Internal Battery Caution Fire, explosion, and severe burn hazard! Misuse or improper installation of the lithium battery can cause severe injury. Do not recharge, disassemble, heat above 100°C (212°F), solder directly to the cell, incinerate, or expose contents to water. Dispose of spent lithium batteries properly. The CR200(X) contains a lithium battery that operates the clock and SRAM when the CR200(X) is not powered. The CR200(X) does not draw power from the lithium battery while it is powered by an external source. In a CR200(X) stored at room temperature, the lithium battery should last approximately 5 years (less at temperature extremes). Where the CR200(X) is powered most or all of the time the lithium cell should last much longer. The internal lithium battery must be replaced periodically. Factory replacement is recommended. Contact Campbell Scientific to obtain an RMA prior to shipping the CR200(X). If the lithium cell is removed or allowed to discharge below the safe level, the CR200(X) will still operate correctly while powered. Without the lithium battery, the clock will reset and data is lost when power is removed. A replacement lithium battery can be purchased from Campbell (part number 15598). TABLE. CR200(X) Lithium Battery Specifications p. 33 lists the specifications of the battery. However, Campbell Scientific recommends that the battery be replaced at the factory. 33
