Hello! My question is about DB9 serial cables. All I need to do is receive data via DB9 output from an already installed junction box. I soldered my male to receive on pin 3 and ground on 5 and my female end on pin 2 to receive and 5 ground. Now I know this is backwards! I don't have the equipment to solder again and I'll be able to test it tomorrow Will a null modem fix this? Or can I flip the cable and use gender bender on both sides? probably not.. Thanks
