ACC-104 Interface cable for SB 2000MKII
ACC -104 mini din for Yaesu :
With ACC104, The CAT doesn’t work directly, because FT847 is different design as other yaesu rigs. This one uses null modem connection. The others all use straight connection. So the solution is to reverse the pin 2 and 3 in the DB9 connector of ACC104. I will recommend to buy a pair of db9 sockets(male and female), then wire them as a null modem to straight adaptor.
