SC115 CS I/O 2G Flash Memory Drive with USB Interface
1. Introduction
The SC115 is a portable 2-GB memory drive (thumb drive) compatible with
Campbell Scientific CRBasic dataloggers that have a CS I/O port. It shuttles
data, OS, and program files between Campbell Scientific dataloggers and a PC,
or it remains connected to the datalogger to augment data memory. It can be
used in tandem with a CompactFlash (CF) card.
The SC115 can also be used as a CS I/O to USB communications interface.
2. Cautionary Statements
• Corruption of multiple data files may occur if the SC115 is removed from
the host datalogger or PC during data transfer.
• Do not disconnect the SC115 from the host while the LED is flashing or
lit. Always use the Safely Remove Hardware utility provided in the
Windows operating system prior to removal from a PC.
• Some data collection modes increase the risk of inadvertently
disconnecting the SC115 from the datalogger during data transfer. See
Section 12.1, Preventing Data Corruption to assess the risk in a particular
application.
• Always click Disconnect in the datalogger support software prior to
removing the SC115 when it is a communications interface. See Section
11, Serial Communications Interface Function for communication
interface details and precautions.
3. Initial Inspection
Upon receipt of the SC115, inspect the packaging and contents for damage.
File damage claims with the shipping company. Immediately check package
contents against the shipping documentation. Contact Campbell Scientific
concerning discrepancies.
4. Quickstart
The primary function of the SC115 is as a portable memory drive (thumb
drive) to collect data from compatible Campbell Scientific dataloggers (see
Section 6, Specifications for compatibility). Simply connect the CS I/O
connector of the SC115 to the CS I/O connector of a properly programmed
datalogger, and data are transferred automatically.
Memory drive setup (see Section 7, Setup for complete instructions):
• SC115 — shipped from the factory ready for use in most applications.

SC115 CS I/O 2G Flash Memory Drive with USB Interface
• PC — requires software drivers be installed. See Section 7.2, PC
Preparation. Install drivers BEFORE plugging in the SC115. When these
drivers are installed, the SC115 performs on the PC as a memory drive
(thumb drive).
• Datalogger — as shown in the following code example, insert the
TableFile() instruction into the datalogger CRBasic program immediately
following the DataInterval() instruction. This configuration enables the
SC115 to collect the newest data in the data collection mode (see Section
8.1, Data Collection Modes). Note that “USB:” is the correct drive name.
For complete programming examples, see Section 10.5, Example
Programs.

5. Overview
The SC115 is a portable 2-GB memory drive (thumb drive) compatible with
CRBasic dataloggers that have a CS I/O port. It can be used in tandem with a
CompactFlash (CF) card. It shuttles data, OS, and program files between
Campbell Scientific dataloggers and a PC, or it remains connected to the
datalogger to augment data memory.
The SC115 can also be used as a CS I/O to USB communications interface.
The SC115 has a USB 2.0 compatible connector used to attach the SC115 to a
PC USB port to allow stored data files to be copies to the PC. It also has a CS
I/O 9-pin connector that attaches the SC115 to the CS I/O port of compatible
Campbell Scientific dataloggers. The SC115 may be connected directly to a
PC or datalogger, or connected through the supplied extension cables.
The 5 Vdc (pin 1) of the CS I/O interface determines whether the SC115 is
used as a memory drive or as a CS I/O-to-USB communications interface. If
the 5 Vdc pin is not driven high, it acts as a memory drive. If the 5 Vdc pin is
driven high by the datalogger, the SC115 will serve as a communications
interface.
5.1 Memory Drive Function
As a memory drive, when the SC115 is attached to the CS I/O port of a
datalogger, the LED (Light Emitting Diode) first flickers as the SC115 and
datalogger negotiate communications. The datalogger determines if the
TableFile() instruction is set to write to an SC115. The LED flickers as the
datalogger copies data files to the SC115. The LED stops flickering when data
transfer is complete, and the SC115 can safely be disconnected.
As a memory drive, when the SC115 is attached to a PC, the LED first lights
solidly as it communicates with the PC to obtain a unique address. Once
negotiations are finished, the LED extinguishes and the SC115 appears as a
removable drive in Windows® Explorer. Data files on the SC115 can be
copied or moved to other drives. Files, such as CRBasic program files or
operating system files, can be copied or moved from PC drives to the SC115.

5.2 Communications Interface Function
As a communication device, the SC115 provides pass-through
communications.

A PC requires software drivers to support the SC115, and the datalogger
requires inclusion of specific code in its CRBasic program. In rare instances,
the SC115 may require a change to its default configuration through Campbell
Scientific’s Device Configuration Utility software v. 1.5 or higher
(DevConfig).
7.1 SC115 Settings (Optional)
The default SDC addressing in the SC115 is adequate for most applications.
For exceptional circumstances, the CS I/O SDC address can be altered using
the SC115 service in DevConfig v. 1.5 or higher (see Section 14.1, SDC
Addressing).
