Campbell Scientific SC932C 9-Pin Interface Specification

The Campbell Scientific SC932C 9-Pin Interface is a crucial component designed to facilitate seamless communication between a Campbell Scientific data logger and external devices such as modems or computers. This interface is specifically engineered to convert RS-232 signal levels to the logic levels required by the data logger, ensuring reliable data transfer and integrity.

The SC932C is housed in a robust, compact casing that guarantees durability and ease of installation in various environmental conditions. Its design includes a 9-pin male D-sub connector, which interfaces directly with the modem or computer, and a 9-pin female D-sub connector that attaches to the data logger, streamlining connectivity without additional complex wiring.

Operating efficiently within a wide temperature range of -25°C to +50°C, the SC932C is suitable for diverse field applications, supporting the rugged and demanding conditions often encountered in environmental data collection. The interface operates without the need for an external power source, drawing minimal power directly from the data logger, which enhances its versatility and ease of use in remote locations.

Weighing approximately 90 grams, the lightweight nature of the SC932C ensures that it adds minimal load to field equipment setups, making it ideal for portable data logging solutions. Its simplicity and reliability are further underscored by its plug-and-play functionality, requiring no additional configuration for standard operations.

Overall, the Campbell Scientific SC932C 9-Pin Interface is an indispensable tool for researchers and technicians who require a dependable and straightforward method to connect data loggers with external devices, ensuring consistent data acquisition and transmission in a variety of environmental monitoring applications.

Campbell Scientific SC932C 9-Pin Interface F.A.Q.

What is the primary function of the Campbell Scientific SC932C 9-Pin Interface?

The SC932C is used to interface Campbell Scientific data loggers with RS-232 devices, enabling communication and data transfer between the two.

How do I connect the SC932C to a Campbell Scientific data logger?

Connect the SC932C to the data logger using the provided 9-pin cable, ensuring that the connections are secure and correctly aligned.

What troubleshooting steps should I take if the SC932C is not communicating with the RS-232 device?

Check all cable connections, verify the baud rate settings on both devices, and ensure that the RS-232 device is powered on.

Can the SC932C be used in outdoor environments?

The SC932C is designed for indoor use and should be protected from harsh environmental conditions. Use appropriate enclosures for outdoor applications.

How can I verify if the SC932C is functioning correctly?

Perform a loop-back test using terminal software to check if data sent is received correctly, indicating the interface is operational.

What maintenance is required for the SC932C?

Regularly inspect the SC932C for any visible damage or loose connections, and clean the connectors to ensure good contact.

How do I configure the baud rate on the SC932C?

The SC932C itself does not configure baud rates; ensure the connected devices have matching baud rates for communication.

What should I do if the SC932C interface gets wet?

Immediately disconnect it from all devices, dry it thoroughly, and inspect for any water damage before reuse.

Is it possible to extend the cable length of the SC932C?

Yes, but ensure that the total cable length does not exceed the RS-232 specification limits to maintain reliable communication.

Can the SC932C be used with non-Campbell Scientific equipment?

Yes, as long as the equipment operates with standard RS-232 communication protocols.
