Overview

The SC105 is a CS I/O to RS-232 adapter used to connect a Campbell Scientific data logger to an RS-232 DCE device. Common DCE devices used with the SC105 include cellular modems, radios, and smart serial sensors. The SC105 is compatible with any data logger that has a CS I/O port. Multiple SC105 interfaces can be connected to a single data logger CS I/O port.

 

Key Advantages

Communication Support

Technical Description

The SC105 provides internal buffering that temporarily stores data. This buffering allows the data logger and DCE device to operate at different baud rates by storing the data received from the faster device until the slower device is ready to receive it. Internal buffering also ensures that no data is lost during transmission.

Benefits

  • Supports communication between a data logger and an RS-232 DCE device
  • Communicates at baud rates up to 115.2 kbps
  • Provides internal buffering capability to ensure no data is lost during transmission
  • Data logger can operate at a different baud rate than the DCE device
  • No power source needed—powered by the datalogger and computer
  • Compatible with most Campbell Scientific data loggers
  • Helps protect components from electrical damage
  • Ships with cables needed for most uses

Compatibility

Cable Connections and Mounts

Three cables (13657 Null Modem Cable, SC12 CS I/O Data Cable, and 10873 Serial Data Cable) are shipped with the SC105. The 13657 cable is used to program the device via a computer. The SC12 cable connects the SC105 to the data logger, and the 10873 cable connects the SC105 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.

The 16987 mounting kit is available for attaching the SC105 to the backplate of an environmental enclosure.

Data Logger Considerations

Note: When using an SC105 with OS version 4 or newer with a mixed-array data logger, the data logger operating system should be updated to the latest released version.
