SC-USB USB to CS I/O Opto-isolated Interface
15
4.1.6 Enable SDC Comms Mode
Selecting ‘Enable SDC Comms Mode’ will force the SC-USB to
only
respond
as an SDC communication device at address 9. In this mode asynchronous
communication is used at the chosen bit rate. The Modem Enable line (pin 5)
is not used and is free for other use. SDC mode allows the SC-USB to be
connected in parallel with modem devices. This mode is only supported in
CR510, CR10X and CR23X dataloggers with post-2002 standard (non-
PakBus) operating systems.
4.1.7 Enable ME Comms Mode
Selecting ‘Enable ME Comms Mode’ will force the SC-USB to
only
respond
as a modem-enabled device. This would only be used when all other
connection modes are being used by other peripherals or for compatibility with
an older datalogger or operating system.
4.1.8 Set ID
Set ID is used to make the SC-USB interface unique. This is useful if you have
more than one SC-USB interface connected to the same PC at the same time.
The default ID as supplied is 00000001.
Close the SC-USB utility when you have finished using it, as its
method of polling the SC-USB may cause the PC to become very
slow when running other programs.
4.2 Operating System (OS) Downloads
The OS download button in the Sc_USB.exe utility allows you to upgrade the
OS in the SC-USB to take advantage of new features and allow new product
support.
When using this option, do not unplug the SC-USB or turn
off the computer, otherwise the operating system may be
corrupted and the SC-USB may then need to be returned to
the factory for repair.
5. Using the SC-USB with Campbell Scientific
Software and Hardware
5.1 LoggerNet EZSetup or Standard Setup
In recent versions, the SC-USB appears as a clearly identified special COM
port device within Campbell Scientific software packages. In older versions or
third-party software, it appears as a standard COM port.
To use the SC–USB, if using the EZSetup Wizard, you need to specify a
“Direct Connect” and then select the new COM port number assigned to the
SC-USB (see Section
Determining Which COM Port the SC-USB Has
(p. 11)
). If using the standard Setup screen in
LoggerNet
, you
need to Add a Root device, select the COM port option and select the relevant
