An Easy Way to Wire your 6000 for Digital Ops - OUCH!

Dave, I'm not surprised about the grounds. The typical video / audio cables for this connector also have shields for the video and audio lines. And the shields are typically connected together inside the HD15 connector. One of the lines, pin 4 is sometimes also grounded and grounding pin 4 will key the transmitter for CW - not good. I built an interface to key the 6700 from the DTR pin on a PC com port and wanted to have access to all 15 pins on the accessory connector. I used a HD15 extension cable that didn't bond any of the lines together. The interface box allowed me to pick off any of the data lines needed. You could also use one of the "breakout" HD15 connector boards. I have one but didn't use it. I preferred the more standard looking connector to plug into the back of the radio, so built an interface in a project box. I only needed to connect to a DB9 for the COM port but you could connect RCA connectors, or others as needed. The full description of the interface is on the Yahoo forum in the files section but here is the cable info below. Regards, Al / NN4ZZ

Greg, I got one of the straight thru extension cables from Winford for my interface. Simply cut it in half and wired it up. Regards, Al / NN4ZZ

Tim, No good reason. I bought 2 of the extension cables figuring I might want to extend the location of the interface box at some point. And also thought I might want a female connector at some point. But I could have just bought one cable of either type for this immediate project. Regards, Al / NN4ZZ
