The SC932A supports two-way communications between a data logger and a device that is configured with an RS-232 DCE serial port. Common Campbell Scientific devices used with the SC932A include our SRM-5A RAD Short Haul Modem and RavenXT-series digital cellular modems. The SC932A can also be used with third-party fiber optic modems, Hayes-compatible modems, satellite transmitters, and spread-spectrum radios. The SC932A is compatible with any data logger that has a CS I/O port.
Benefits and Features
- Communicates at baud rates up to 115.2 kbps
- Provides true RS-232 signal levels
- Compatible with most Campbell Scientific data loggers
The SC932A is a 9-pin to 9-pin interface. Modems with a 25-pin DCE serial port, such as the SRM-5A, connect to the SC932A via the 15751 adapter.
This interface provides true RS-232 signal levels. It does not support one-way output or printers; our SC105 interface is recommended for those applications.
