SC932A
SC932A
OrderableRS-232 DCE Interface, CS I/O to 9-Pin
Overview
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.
Technical 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.

Peripheral Mounting Kit
The 16087 provides hardware for affixing an SC932A to an enclosure backplate. This mounting bracket attaches only the SC932A to the backplate; the 6282 bracket kit is available for attaching both the SC932A and SRM5A.

SRM-5A and SC932A Mounting Kit
The 6282 bracket kit attaches both the SRM5A and SC932A to an enclosure backplate.
Orderable8125
Flat-Bladed Screwdriver, 2.5 mm Blade x 50 mm Shaft
If not ordering the datalogger on the same order, you might need this small, flat-bladed screwdriver. The 8125 is extremely useful for opening the guillotine terminals on this interface. The blade is 2.5 mm across and the untapered shaft length is 50 mm. The handle has an approximate length of 9 cm, and features a rotating end-cap that makes the screwdriver easy to rotate.

Spacer Jack for Screw #4-40
This spacer is needed if screws are used to secure the cable to the device.
Orderable10873
Serial Data Cable, 9-Pin Socket (Female) to 9-Pin Pin (Male)
The 10873 is a serial cable that is useful for connecting the RS-232 port of the datalogger to the 9-pin RS-232 port of a computer. The cable is six feet long.

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.
