In some cases a PC program may not offer the SC-USB COM port in its selection 

list of available COM ports.  Recent versions of Campbell Scientific packages 

allow you to manually type the COM port into the selection window to overcome 

this. 

 

Older software may also limit you only up to COM4.  In that case you would need 

to free a lower com port numbers (by deinstalling an unused COM port) and move 

the assignment of the SC-USB.  To do this right click on the SC-USB in the 

device manager screen (as shown above) and select properties.  Then select Port 

Settings and then the Advanced button.  In the next screen you have the option to 

change the COM port number to another free number.  ‘OK’ any change you 

make and close the Device Manager screen before reopening it to confirm the 

change (it does not automatically refresh this change). 

 

 

The  Baud  rate  settings  in  the  driver/properties  setting  have  no 

influence  on  the  operation  of  the  SC-USB.    The  speed  of 

communication  to  the  datalogger  is  normally  determined 

automatically by the SC-USB although it can be set in other ways, 

see the sections below. 

3.5  Using the SC-USB with Campbell Software 

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 3.4 above). If using the setup
