I am looking for the schematic diagram for the Kenwood IF-10d interface. I want to CAT-interface my TS-50, but the IF-10d is a disclosed item at Kenwood.
I managed to find a diagram of the IF-232 by TK5EP (http://tk5ep.free.fr/
), which converts the RS-232 to TTL level, but I have no clue what the IF-10d does. I believe the only thing it should do is buffer the 4 serial data lines (RxD, TxD, CTS and RTS) available on the TS-50's CN6 connector, and perhaps also invert (some of) them. Does anybody own an IF-10d, and wants to take a look at the board layout and the ICs that are on it?
Also, does the TS-50's serial data interface need to be enabled somewhere in the software menu? I see no signals on it whats however, even when I pull CTS high.
Has anybody managed to homebrew a CAT interface for the TS-50? I'd be interested in any suggestions you might have.
