The MCR1 is only compatible with our mixed-array data loggers and the DSP4 Heads Up Display. (See the Compatibility information.) In a single package, it includes both the CSM1 and a SC532(A). The MCR1 connects to an IBM-compatible computer via a 7026 cable (supplied). AC power and SMS software are required. Please note that availability varies by country; please contact a Campbell Scientific office or representative to discuss your data storage requirements.
