Hello,
As far as I know there is no other way to connect Thingworx to the Raspberry Pi.
However I can explain step 5 to you:
Step 5 is used to verify that the unzip operation on the zip file was successful.
The command you're asked to execute "ls -l" lists the files and directories of the current path you're in, the "-l" switch is used to show further details, size, modified date and time, permissions and owners.
In the list provided you should find the folder microserver which indicates a successful unzip operation.
In case your list is too large and not conveniently readable you can pipe the output of the command to a file, that you can then open in a text editor. This can be done like so:
"ls -l >> list.txt" and will create a file called list.txt with the content of the commands output.
In Step 6 you [c]hange [d]irectory by running cd microserver which directs your current shells path to the microserver directory.
Let me know if you still have questions regarding the steps.
Regards,
Pascal
