Data Cables / SC932A
SC932A RS-232 DCE Interface, CS I/O to 9-Pin

Overview

The SC932A supports two-way communications between a datalogger 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 datalogger that has a CS I/O port.

Detailed Description

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.

Additional Compatibility Information

Cable Connections

Two cables (SC12 CS I/O Data Cable and 10873 Serial Data Cable) are shipped with the SC932A. The SC12 cable connects the SC932A to the data logger, and the 10873 cable connects the SC932A to the RS-232 DCE device. An SC12R-6 cable (purchased separately) may be used instead of the SC12 cable if a longer cable is required.
