SC-USB USB to CS I/O Opto-isolated Interface

COM port number; then Add the datalogger or PakBusPort directly to the new
ComPort.
In general, the baud rate settings that are offered in the EZSetup or Setup
screens can be left at the default settings as they do not apply to the SC-USB
which determines the best speed to use by automatically negotiating this with
datalogger (see Section
Auto Detect (Automatic Baud Rate Detection)
(p. 13)
, for exceptions).
The SC-USB should plug into and work with any standard USB
1.1 or 2.0 compatible port.
5.2 Using the Device Configuration Utility (DevConfig)
5.2.1 Accessing DevConfig
The SC-USB can be used with
DevConfig
to change datalogger settings. To do
this, open
DevConfig
and connect the datalogger to the PC’s USB port via the
SC-USB. Select the appropriate datalogger from the list. For the COM port,
select the new COM port number assigned to the SC-USB (see Section
Determining Which COM Port the SC-USB Has Been Assigned
(p. 11)
), and then
press Connect.
5.2.2 Downloading a Datalogger OS
The SC-USB can be used to download operating systems to the CR510,
CR10X, and 23X dataloggers using
DevConfig
. This requires that the
SC-USB utility be used to set the baud rate to 19200 and the comms mode to
ME Comms Mode. See Section
(p. 13)
, for information about
changing these settings. After loading the operating system with
DevConfig
,
remember to set the SC-USB back to its default setting to allow normal
communications afterwards.
You cannot load operating systems into the CR6, CR800, CR850, CR1000, or
CR3000 dataloggers by selecting the “Send OS” tab in
DevConfig
because
these dataloggers only support the low-level OS upload via the RS-232 port.
However, you can load an operating system into these dataloggers using the
option to load a program into the datalogger (under Logger Control) and
changing the file type to operating system. (You can load the OS with other
Campbell Scientific programs too using the program load options.) This
technique does not reset as many settings as the lower level “Send OS” option.
5.3 Use with the DSP4
It is possible to use the SC-USB to communicate with most dataloggers when
they are used with a DSP4 Heads-Up Display. As with other means of
communication, display of data on the DSP4 is suspended during
communication.
For the CR5000 it is
not
possible to run any program that sends
data to the DSP4 and then communicate with the SC-USB. This
is because the CR5000 reserves the CS I/O port solely for use by
the DSP4. Contact Campbell Scientific for further information.
