Scanner SDK for Windows - ParameterDefaults


First off let me say thanks to the devs for providing the SDK and all the resources for a fast and easy coding.
I'm using a handheld LI4278 scanner, connected via bluetooth, and I'm having trouble using method #6001 - ParameterDefaults.
In the documentation there aren't any examples for opcodes 6001-6022. They're described in the same table as #6000 so I followed the inXML template described for opcode #6000.
Attached is my call to ExecCommand (Seems like putting xml here is illegal)
It returns with status code 107 - Invalid Argument

Thanks in advance!
