Hi stereogeezer,

Your posting is a bit confusing. The original cable for the RC9200 has a minijack at one end and a serial connector at the other. It is the same cable as the Pronto TSU6000!

If you look at this link your cable should look similar [Link: testproducts.com]

The cable for the RC3200, RC5000, RC5000i, RC5200, RC9200 and the Pronto TSU500, TSU1000, TSU2000, TSU6000 all use the same cable.
