The Pixelink SDK includes the tools needed to develop your own applications using the Pixelink API.

This means that the C/C++ header and library files are included so that you can write code in C, C++, or .NET that calls functions in the Pixelink API.  The runtime of the API is in a single DLL, PxLApi40.dll.

Otherwise, Pixelink Capture and the Pixelink SDK contain the same camera control software and tools – Pixelink Capture, Capture OEM, Wizards, etc.
