SC-USB USB to CS I/O Opto-isolated Interface
The SC-USB is designed to allow Campbell Scientific dataloggers to communicate directly
with computers fitted with a USB interface. It provides an isolated connection which can
also operate at higher speeds than conventional RS-232 connections.
1. Introduction
The SC-USB is optically isolated thus preventing possible noise pickup
associated with PC power supplies and ground connections. It also supports
synchronous communications modes, available in some models of dataloggers,
which allow multiple devices to be connected in parallel. The SC-USB can be
used in place of an SC32B interface. The SC-USB also has the potential for
high-speed data transfer to the PC at up to 1 MBit/second where the datalogger
supports it.
Originally, the SC-USB was fitted with an integrated USB cable. At the end of
2009, the SC-USB was redesigned to include a connector instead of the
integrated cable. A 17648 USB cable attaches to the new connector. This
cable is shipped with the SC-USB.
The SC-USB will appear in PC software as a new virtual serial port, allowing it
to be used with many software packages.
NOTE
The SC-USB PC drivers support various operating systems including Windows
98/ME, 2000, XP, Vista, and 7. The SC-USB is shipped with a software CD
containing suitable drivers and a set-up/programming utility called Sc-USB.exe
which can be found in a directory named ‘Utility’ on the CD. The CD also
contains a comprehensive help file, and manual. These files can be accessed
directly from the CD, if required, by double-clicking on the icon 'index'.
The SC-USB will normally operate ‘straight from the box’ for most
applications using the default settings. However, you can change the baud rate,
the communication rate, and its USB ID by using the Sc-usb.exe set-up utility
provided (see Section 3.2). This utility can also be used to upgrade the
SC-USB’s operating system.
Please check with Campbell Scientific if you wish to use the SC-USB with a
CR9000X.
If you are using a CR5000 datalogger, make sure the datalogger
operating system is version 2.0 or later as this will enable the
highest communication speeds. For older versions set the
SC-USB to work in ME Comms Mode (see Section 3.2).

2. Technical Specifications
2.1 USB Specifications
• USB Version 1.1
• USB transfer rate up to 12 MBits/second
• Active current consumption less than 85 mA (current drawn from PC)
• Standby current consumption less than 18 mA (current drawn from PC)
• 17648 Cable Description: 6 ft (1.8 m) length; USB Type A male to Type B
male.
2.2 CS I/O Port Specifications
• Opto-isolated from the PC/USB to 47 V AC or DC. Note that this is
signal isolation only, and does not provide safety isolation.
• Supports asynchronous communication from 9600 to 115200 baud and
synchronous communication up to 1 MBit/second.
• Campbell Scientific protocols implemented: supports Modem-Enable
(ME), Synchronous Device Communications protocol (SDC) and
Concurrent-SDC (CSDC) modes. Some of these modes may require that
the datalogger operating system be a specific version or higher. The SDC
mode only works with operating systems created since October 2002
(CR10X 1.18 or higher, CR23X 1.15 or higher, etc.) The CSDC mode
only works with a PakBus (PB) operating system and the CR5000.

PB, CR23X / TD / PB, CR800 series, CR1000, CR3000 and CR5000.
• PC software compatibility PC200W, PC400, LoggerNet, RTDAQ and
most other packages that support virtual serial ports.
• Active current consumption less than 19 mA (current drawn from
datalogger).
• Quiscent current consumption less than 80 µA (current drawn from
datalogger).

CD (Contact Campbell Scientific for other drivers)
2.4 Ships With
SC-USB USB to CS I/O Opto-isolated Interface
• 17648 USB cable for connection to the PC’s USB port.
• SC12 CS I/O cable for connection to the datalogger.
• Driver CD containing setup utility and manual.
• ResourceDVD.
3. Using SC-USB Driver and Setup CD
3.1 Drivers Installation
The installation procedure is straightforward. The Windows set-up wizard will
guide you through the installation steps as indicated below.
This guide assumes that you are installing the drivers onto a ‘clean’ system
(i.e., one on which similar drivers have not been installed previously). If this is
not the case, then you should first uninstall the existing drivers using the
standard Windows procedure (see below). If upgrading your drivers from a
previous version of SC-USB driver, it is also important to deinstall the
previous drivers first to avoid conflicts.

3.1.1 Windows 7
Connect the SC-USB to a spare USB port on your PC. If there is an available
internet connection, Windows 7 will silently connect to the Windows Update
website and install any suitable driver it finds for the device. If no suitable
driver is found automatically, you will see a message similar to this...
...if so, use the following procedure to update the driver.
Click the Windows start button to bring up the start menu and click ‘Control
Panel’ as shown below...
