Newbie Question-CDJ and remote

From what I have read it seems that it is possible to control CDJ using a remote. Is this true? If so, can any remote be used,ie. can I use the remote that comes with the CDPCX400 changer or my Sony DVD remote,etc. It seems that a device file is needed. Is this file associated with the remote doing the controlling? Is there one for the above changer/DVD remotes. If all this is so, can someone please provide me the procedure for doing so or a least point me to the appropriate documentation. Thanks for taking the time to help a novice at this.
