What connects to the data logger RS-232 port?
The RS-232 port is used for communication with computers, modems, and radios. It is also used for communicating with, and retrieving data from, serial sensors.
- The RS-232 port on CR3000 and CR5000 dataloggers is electrically isolated.
- The RS-232 port on the CR800, CR850, and CR1000 is not isolated. For these data loggers, it may be preferable to connect ac-powered PCs to the CS I/O port instead of the RS-232 port to avoid ground loops on some measurements.
