SC-USB USB to CS I/O Opto-isolated Interface
14
sessions. It is currently supported by Pakbus dataloggers and recent versions of the
CR5000 operating system.
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 Updating the Operating System of the SC-USB
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.
4.3 Uploading Datalogger Operating Systems
The SC-USB can be used to load operating systems into CR500, CR510, CR10X
and CR23X dataloggers, using the CSOS or Device Configurator Programs. This
requires the SC-USB utility to be used to set the baud rate to 19200 and the
comms mode to ME comms mode.
After loading the operating systems in the way described in the relevant program,
remember to set the SC-USB back to its default setting to allow normal
communications afterwards.
The SC-USB cannot be used to load operating systems in a similar way for newer
loggers – see Section 5.4.
