SC-USB USB to CS I/O Opto-isolated Interface
3.2 Set-up Modes – the SC_USB Programming Utility
The Set-up button on the SC_USB.exe utility allows you to configure the
SC-USB interface to work with the supported dataloggers and peripherals and
their modes of operation. Before pressing the Set-up button, ensure that the
correct COM port is selected.
This program is only needed for some older dataloggers or
datalogger operating systems. NOTE
The set-up screen is shown below, and the set-up modes are explained in detail.
3.2.1 Settings
3.2.1.1 Auto Detect (Automatic Baud Rate Detection)
Auto Detect will try to connect at the highest asynchronous baud rate the
datalogger can support. This can be used in most cases. The exceptions are:
• Upgrading a datalogger operating system using CSOS.EXE, when the SC-
USB must be set to 19200 baud.
• Using Call Back, when you must fix the baud rate.
• Using a 21X or CR7 datalogger, where the baud rate needs to be fixed and
set to either 9600 or 76800 baud (OS dependent).
• Using a non-PakBus CR23X-TD datalogger – the baud rate may be
adjusted to the maximum supported by the datalogger. (By default it will
run at 9600 baud.) See Section 5.2 for more details.
Auto Detect is the Factory default.
