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 RS232 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, that 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 1MBit/second where the datalogger supports it.
The SC-USB will appear to PC software as a new virtual serial port, allowing it to
be used with many software packages.
The SC-USB PC drivers support various operating systems including Windows
2000, XP, Vista, Windows 7 and 8. 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 running the setup program.
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
