Some interfaces use DTR or RTS to power the interface.
Try using the other one for power.
What is your CAT interface used.

That sounds as if you are using RTS on the CAT control port for PTT, but your interface requires RTS on the CAT control port to be always on for it to work. If that is the case, you may not be able to use RTS on the CAT control port for PTT - you may have to use a different serial port for PTT from the port you are using for CAT control.
