Campbell Scientific SC32A RS-232 Interface The Campbell Scientific SC32A is an optically isolated RS-232 interface designed to facilitate seamless communication between a computer and compatible data loggers. By converting the CMOS logic levels of the data logger’s serial I/O port to the RS-232 levels of a computer, the SC32A ensures reliable data transfer and device configuration. Key Features Optical Isolation: The SC32A provides electrical isolation between the data logger and the computer, protecting against ground loops, static discharge, and noise interference. RS-232 Compatibility: It converts the data logger’s logic levels to standard RS-232 levels, enabling direct connection to a computer’s serial port. Flexible Connectivity: The interface connects to the data logger’s 9-pin CS I/O port via an SC12 or SC12R-6 cable, and to the computer’s serial port using a standard RS-232 cable. Extended Cable Lengths: Supports RS-232 cable lengths of up to 50 feet, providing flexibility in system setup. Specifications Operating Temperature: -25°C to +50°C Power Supply: Powered by the connected devices Ports: 25-pin female RS-232 port configured as DCE; 9-pin male port for connection to data logger Dimensions: 130 x 60 x 25 mm Weight: 0.1 kg Applications The SC32A is ideal for applications requiring direct communication between a computer and Campbell Scientific data loggers, such as the CR510, CR500, CR10(X), 21X, or CR7 models. It ensures data integrity and system protection in various environmental monitoring and data acquisition setups. Included Accessories SC12 cable for connection between the data logger and the SC32A Standard RS-232 cable for connection between the SC32A and the computer’s serial port By providing robust isolation and reliable data conversion, the SC32A enhances the performance and longevity of data acquisition systems in diverse operational environments.
