Hello All,
Been away from the list for quite some and old Rip Van Winkle here has just awakened. I'm looking to use my venerable OMNI VI Opt.3 with my computer to do logging and rig control. The freeware program by N1MM has been highly recommended to me. Any suggestions or warnings here?
In addition, I believe a serial cable is needed to interface the OMNI VI to the computer. The OMNI has a female DB-25 and my computer has but just one male DB-9 (luckily not being used.) From the wiring diagram at the rear of the OMNI VI manual there appears 2 serial cable diagrams. One using a DB-25 and DB-9, the other using 2 DB-25s. The wiring seems different. Not being knowledgeable about these cables, I put together some cables to give myself a DB-9 female at one end and a DB-25 Male at the other end. The pinout continuities do not match what's in the manual. Does such a cable exist or do I have to fabricate one? Any suggestions are welcomed. 
I can use all the help I can get and I feel this will be a steep learning curve for me. Maybe I don't know what I'm getting myself into!
Again many thanks in advance.
Art, N2KA
