I purchased a proprietary adapter for lighting control panels, but it was also obsolete, being RJ12-DB25. The pinout was proprietary and undisclosed, so I was stuck with a $65 pricetag. Modifying the interface further would require a DB9 to 25 bridge first and foremost. And at under a buck and a half, this was a necessity -- and it did NOT dissappoint.
ProsSimple, straight forward answer to an obsolete interface.
